An embedded CPU based automatic ranging system for vehicles

Based on the structure and theory of optical-mechanical-electrical automatic ranging system of vehicles, paper has a discussion and research of the architecture and design of auto ranging system with risk estimation and decision making basing on embedded CPU. The solution of embedded system has got a good real-time performance and it can promote the data processing capability of the system. Paper mainly introduces the defects of SCM (Single Chip Micyoco) based ranging system and the hardware architecture, software architecture and some other key technology of the embedded system based ranging system, etc. It also introduces the solution of using two lidars light detection and ranging method.
