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

some of the results can be seen in the following pictures.

3d laser scanner with rotating table

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 a case around the scanner to shut out ambient light.
one of the biggest challenges in building this scanner was the bending of the cylindrical front door. in order to bend the acrylic i had to build an aluminum model on which i placed the acrylic in the oven.

some of the results can be seen in the following pictures.

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 a whole. the laser is positioned relative to the camera very approximately.
