Recently, a Github host in Russia opened source a DIY lidar project, from PCB to PC software is open source. The lidar effect is as follows:

 

The performance indicators of the lidar are as follows:

  • Scanning speed: 15 times per second
  • Resolution: approximately 1% of detection distance, but no better than ±2 cm
  • Minimum detection distance: 5 cm
  • Maximum detection range: approx. 25 m (white reflection plane)
  • Angular resolution: 0.5 degrees
  • Scanning frequency: approx. 11 kHz
  • Scanning Angle range: about 230 degrees, change the corresponding structure has some room for improvement
  • Power: 5 V/0.1 A (i.e. 0.5 watt), voltage may exceed 0.8A at startup
  • Size: 50x50x120 mm

The lidar structure rendering is as follows:

Lidar uses the TOF (Time-of-flight) rangefinder principle. This type of rangefinder is actively used by the military. They are used in geodesy, earth remote sensing, industry, autonomous vehicles and other fields.
