Design and implementation of embedded vision measurement sensor based on ARM system

This paper designs a vision measurement sensor based on vision measurement technology, which consists of the embedded Linux system, ARM kernel microprocessor system, a camera and a line structured light projector. A laser plane is projected on the object surface, and the vision sensor captures the laser stripe images. The images are processed and image features are extracted in the embedded system. The depth information of object surface and 3D coordinates are calculated and obtained by model calibration. The measurement data can be transmitted via Ethernet, serial port and field bus, and an embedded vision sensor is developed for industrial filed applications. The vision sensor prototype and experimental results verify the proposed system.
