Luckily, the technology it is based on may be replicated — even with a limited expenditure — as we will show you in this article, in which we will propose the construction of a scanner based on Raspberry Pi 2, the well-known prototypation board. The structured light technology offers excellent results but involves a complexity and costs that not always may be acceptable ones, while the ones that proved to be the most affordable ones are the laser technology plus video camera and the video camera one: in the first one, that is the one you will see applied to the project in this article, one or two lasers draw a vertical line on the area to be scanned, and a video camera shoots the surface lighted by the laser. Ultimately, there is no technique being better than the other one, but each one is more indicated for a certain kind of objects to be shot, and for certain scan conditions. Usually, in these systems two lasers tilted with respect to each other are used, and the video camera is placed between the two. Our scanner is born out of an elaboration of the PiClop, an open project composed of a mechanics whose parts to be 3D printed may be downloaded from and of an electronics formed of the Raspberry Pi 2 board and its video camera; PiClop, as implied by the name, is a free interpretation, based on , a 3D commercial laser scanner and a video camera, supplied with a rotating plate. Even Ciclop though it is commercialized is a scanner having an open source information material. We preferred a video camera having an adjustable lens so to optimise the focus of the object, since we realized that the original one in the Raspberry Pi has a focus distance that is greater than the one between the base and the rotating plate that hosts the object to be scanned. Being able to accurately regulate the focus, we are able to obtain the best definition in the calibration stage, before starting the scan. The software implements a web interface, by means of which it is possible to operate with the scanner, that is to say, to carry out the settings and the acquisitions. For each acquisition a file is generated. You will have to adjust the settings during the configuration, according to what we will explain later. The laser integrates a collimating aspheric lens in order to direct the light to a single point, that is then transformed into a line thanks to a cylindrical acrylic lens, placed at the exit of the laser ray, so to create a light beam having a triangular section with an opening of about 45°. In order to acquire all the needed information, the object is rotated by an angle, chosen at your discretion, even though usually a complete rotation 360° is carried out. The linear laser beams are inclined between them by 60° on the horizontal plane, therefore the video camera, since it is centered with respect to the two lasers, is placed with a 30° angle with respect to the beam of each one of them. When the scan is started, Raspberry Pi 2 will begin to acquire the images frame supplied by the video camera, with a periodicity set by the software: the default value is 800 per whole revolution of the plate and therefore, of the object , but we also tried to operate with 2,000 frames per revolution. The need to use a second laser arises when you need to scan, for example, a cube: in this case, in fact, when using a single laser only, some grey areas are created because of the misalignment that is to say, the different angle with which the two elements address the object to be scanned between the video camera and the laser. If we add a second laser, tilted by 30 degrees in the counterclockwise direction, the grey areas disappear: in fact, when the object rotates and goes beyond the critical angle of the first laser, the grey area is scanned by means of the second one. For each frame, Raspberry Pi 2 analyzes the lighted zone, and discards the rest of the image, that is used just for the purpose of verifying the correct sequence for queueing the slices; by putting the slices together the image is reconstructed. The scan preview will appear on the monitor, as well as the file save in the desired format, the first one will be carried out with a resolution that is inferior to the one that will be set for the actual scan. If we approve the preview, we may start the download. In figure you may see what happens when the value set for the Laser Threshold is too low; Figure shows what happens when we set an excessively high one. Finally, in follow figure you may see how the image will appear if the Laser Threshold value is a correct one. Once the lasers have been calibrated, the small yellow and green crosses they may be seen in the test will overlap. If the lasers are not calibrated, the crosses will not appear as overlapping or they are only partially doing it. The values are predefined in the specific drop-down menu, it is possible to access it by clicking on it, they correspond to as many modes: 0. Frames Per Revolution indicates the number of frames shot during the scan 800 is the default value. If the line s turn s out to be discontinuous dotted we need to lower the value, while if they turn out to be jagged or very confused they have an aura we need to raise it. Create Base for Object adds a flat base to the object, so to simplify the 3D printing. Please power the shield with 12Vcc for the motor and with 5Vcc — 1 A for Raspberry Pi 2. Please refer to the table in figure. The two pictures in figure help to clarify the concept. Please make sure that the laser beams perfectly overlap. If you do not place any object on the rotating plate, the system will return the error message shown in figure , above the picture. Please put now the object to be scanned on the rotating plate. Please click on the Test button, in order to verify if the Threshold value is a correct one. At the end of the operation a box will appear — with a miniature of the scanned object — from there it is possible to download the scan files in different formats. The object may be seen again in 3D format, by clicking on the View button or it may be deleted by clicking on the Delete button. The downloaded files may not be immediately used for the printing, however, since they contain some errors: the figure shows the import in Repetier Host and the errors being highlighted; In figure shows the model as repaired and made hermetic. Well, with this we have concluded; in the next installment we will see the scanner version with the video camera only. As for the scan it uses lasers and a video camera and it has a scan accuracy of 0. Many scanners work just like GoScan 3D. Kinect works like this: the infrared projector projects a specific pattern, made of equidistant dots. In order to understand this better, imagine to place a polka dot blanket on a surface of an object: it is possible to identify the shape of the said item on the basis of how the dots are arranged, as the blanket gradually wraps the item itself. In order to acquire with Kinect and similar devices, you need a Personal Computer and the ReconstructMe software with the appropriate software for the sensor that has been used. A program that may be an alternative to ReconstructMe is Kscan3D, but in this case the Trial version does not allow to save the model, therefore it would not allow you to reach the printing stage it is used only to evaluate its functions. In order to carry out the scan via Kinect and similar devices the object must be placed before it on plate or a rotating stool, after that please place Kinect on a stable tripod. In addition to these techniques, there is a laser and video camera scan the lasers are two of the rotating object, that is the subject of this article. A technology that produces excellent results is — on the other hand — given by the fusion of stereoscopic and photometric data that, for example, is implemented on the Fuel3D Scanify scanner; there are still two lasers, but the video camera is a stereoscopic one and is calibrated on them. During the scan it supplies two kinds of data: 3D images and corresponding photometric features; the whole occurs in less than a tenth of a second. Afterwards, it processes the two pieces of data and compares them, so to have a very high accuracy. Such a system is ideal in order to acquire human faces, cloth weaves or natural elements such as flowers and plants. There is also the valued technique of the structured light scanning: a scan projects a known light diagram — typically having horizontal and vertical parallel lines — on the surface to be acquired. A faster and more versatile method is the projection of luminous diagrams that consist in many lines at a single time, or of arbitrary luminous fringes. The light strips may be generated by means of interference of laser sources or via projection method. In the first case, two planar light sources are let to interfere between each other: the result is the creation of regular and equidistant lines. The size of the fringes may be modified by changing the angle between the two beams. This method allows to generate a very accurate pattern that has a great depth, but it is an expensive one, it suffers from reflection and from the typical flaws of the laser sources speckles. The projection method takes advantage of means that generate incoherent light, that is to say the projectors; if on a side some small discontinuities are found in the scan due to the pixel edges that compose the picture , on the other one they may be diminished by lens focusing. In both cases, the picture that is gradually created on the lighted surface is acquired by means of one or more video cameras. About us is the brainchild of a world leader in hobby electronics. Our mission is to become a reference Open Source hacking site with ideas and feedback aimed to enrich the community.

3d scanner selber bauen raspberry pi

Da in meinem Projekt zur , in dem ich des Öfteren meinen 3D-Drucker verwendet habe, mehrmals der Wunsch geäußert wurde, diesen doch einmal vorzustellen, kommt dazu jetzt ein kleines Projekt. Bei diesem Projekt handelt es sich nicht um eine detaillierte Bauanleitung. Eine solche wäre in diesem Rahmen kaum möglich und ich empfehle jedem, der sich ernsthaft für den Bau eines Druckers interessiert, sich gut in diese Thematik einzulesen. Die Anschaffung eines 3D Druckers eröffnet sehr viele, völlig neue Möglichkeiten und der folgende Absatz ist nicht dazu gedacht jemanden davon abzuhalten einen 3D Drucker zu bauen. Es gibt noch unzählige andere Arten, wobei die bekannteste wohl das Prusa Prinzip sein dürfte. Das Prusa Prinzip ist einfach zu bauen, allerdings begrenzt in der maximal möglichen Geschwindigkeit. Die Grundkonstruktion besteht aus Aluprofilen, die miteinander verschraubt sind. Daran werden Halterungen für die Führungswellen befestigt. Beim Zusammenbau ist es besonders wichtig auf korrekte Winkel zu achten. Der Drucktisch besteht aus einer Plangefrästen gegossenen Aluplatte, die auf beiden Seiten aufgehängt ist. Die Platte sollte gegossen sein, da sie sich sonst beim Aufheizen verziehen kann. Zur Aufhängung wurden an beiden Seiten wasserstrahlgeschnittene Aluplatten verwendet die jeweils an 2 Wellen laufen. Wie bereits in der Einleitung geschrieben, arbeitet der Drucker nach dem Ultimaker Prinzip. Die Schrittmotoren sind dazu direkt mit zwei der äußeren Wellen verbunden. Über Zahnriemen wird die jeweils parallel dazu laufende Führungswelle und die bewegliche Welle an der der Kopf befestigt ist bewegt. Die Aufhängungen sind am Profilrahmen mittels Druckteilen befestigt. Hier beißt sich natürlich die Katze in den Schwanz und man benötigt für den Bau Zugriff auf einen bereits fertigen Drucker. Das Gehäuse ist handwerklich nicht anspruchsvoll gestaltet und wurde einfach stumpf verschraubt. Die Platten wurden danach noch mit Osmo Dekorwachs weiß gestrichen. Oben und in der Tür befinden sich Plexiglas Einsätze um dem Drucker beim Arbeiten zuschauen zu können. Integrierte Gehäuselüfter, die zur Temperatursteuerung am Raspberry hängen, verhindern eine zu hohe Bauraumtemperatur. Um den Drucker komfortabel über eine Weboberfläche bedienen zu können, ist zusätzlich ein Raspberry Pi auf dem Octoprint installiert ist verbaut. Durch verbieten des Schreibzugriffes auf die Systempartition ist sichergestellt, dass das System auch bei häufigem Ausschalten ohne Herunterfahren wieder sauber startet. Der Arduino wird mit dem Raspberry verbunden, von wo er auch seinen Strom erhält. Der Raspberry wird über einen Step-Down Regler aus dem 24V Netzteil versorgt, so ist nur ein einziges Netzteil im Drucker notwendig. Die restliche Elektronik ist quasi Standard. Abschließend möchte ich noch kurz auf die wohl häufigste Frage eingehen, die einem zum 3D Drucker gestellt wird. Für vieles gibt es fertige Modelle zu finden, das meiste muss aber selbst erstellt werden. Einsetzen kann man einen Drucker natürlich für Ersatzteile, kleine Werkstatthilfen und Gehäuse. In meiner Werkstatt verwende ich ihn z. Auch beim Bau meiner und den habe ich den Drucker eingesetzt.
