3d scanners

historischer markt aarau 3d coin scanner

objective build a cheap 3d scanner to scan small objects, such as coins, at a very high resolution. scanning principle the scanner projects light onto the surface of an object such that it is partially illuminated. the transition from bright to dark is analyzed and a 3d section of the object is reconstructed via triangulation […]

scanner4 3d scanner #4

this 3d laser scanner is the most complete system i have built so far. it features a calibration system that is used to calibrate the camera as well as the position of the laser relative to the camera. the main components of the system are: line laser with drive usb webcam calibration object control software […]

scanner3 3d scanner #3

it seemed interesting to scan an object not just from one side but all around in one pass. a rotating table on which the object can be placed would do just fine. other than that this scanner is very similar to the 3d scanner #2. in order to improve capturing of dark surfaces i built […]

scanner2 3d scanner #2

my first 3d laser scanner was a proof of concept device. therefore it’s a relatively simple setup with a usb camera, a stepper motor controller, a stepper motor on which a line laser is mounted and a simple program to run the system. camera distortions are partially corrected but the system is not calibrated as […]

scanner1 3d scanner #1

my first 3d scanner is a touch probe scanner that scans very accurately at a very high resolution along each axis. the scanner works very slowly since the probe has to be moved into contact with the object at every point on the xy-coordinate grid. some of the results can be seen in the following […]
