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 the camera alone and then the laser is placed at a certain distance from the camera.
some of the results can be seen in the following pictures.
