3d scanners

historischer markt aarau 3d coin scanner

objective of the project to 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 only part of the object is illuminated and the rest remains dark. the transition from bright to dark is […]

scanner4 3d scanner #4

this 3d laser scanner is the most sophisticated system i have ever built. it features a calibration system to calibrate the camera and to find the laser relative to the camera, no matter how the laser was placed. the components of the system are the following: line laser with drive usb webcam calibration object control […]

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 really just some kind of proof of concept device. therefore it’s a relatively simply setup with a usb camera, a stepper motor on which a line laser is mounted, a stepper motor controller and some software. it doesn’t use any kind of automatic calibration. the calibration is done for […]

scanner1 3d scanner #1

my first 3d scanner is a touch probe scanner that scans very accurately due to the very high resolution along each axis and a very fine touch probe. the scanner works very slowly. the reason is that the touch probe has to contact the object at every point of the x-y coordinate grid. some of […]
