Laser Scanning Measurement based on Event Cameras.

This study aims to develop a three-dimensional measurement system based on the principles of dynamic visual sensors and line laser rotation scanning, suitable for high-dynamic and high-speed environments. The system comprises two CeleX-V event cameras, an electric turntable, and a line laser. The event cameras have high resolution and operate in an event pixel with external timestamps mode for high-speed event detection and information output. After successfully calibrating the stereo event cameras, we employed MATLAB for image processing and point cloud data generation. Finally, a self-built measurement system was used for three-dimensional contour recovery and measurement experiments to validate system accuracy. This system provides an efficient approach for dynamic three-dimensional measurement, fully leveraging the advantages of dynamic visual sensors.
