Abstract

The invention discloses an early warning device of a vehicle based on binocular panoramic stereoscopic vision, and relates to the field of intelligent driving. The early warning device comprises an external collection device and an internal control device. The external collection device collects panoramic stereoscopic images around the vehicle through three binocular stereoscopic cameras with horizontal visual angles and same included angles, the images are processed by a central processing unit of the internal control device, image splicing, environment recognition and speed detection and judgment are achieved, and an alarm device gives out early warning. According to the early warning device, a vision-based sensing technology is adopted, the data is easy to obtain, and the information amount is large; meanwhile, due to the adoption of a single sensing technology, the complexity of the system is reduced, and therefore the cost is reduced; meanwhile, real-time early warning on potential danger of the vehicle is achieved, and the driving level of the intelligent vehicle is further increased.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to a vehicle early warning device based on binocular panoramic stereo vision. Background technique [0002] In recent years, with the rapid development of Internet technology, high-precision positioning technology, and intelligent driving technology, the market's demand for active safety and intelligentization of automobiles has continued to increase, and the social and economic value of intelligent driving technology has become increasingly prominent. The research of scientific research institutions on intelligent driving technology is becoming more and more popular. [0003] The intelligent driving system needs to acquire and process the environmental information in real time during the driving process. As for the acquisition method of the environmental information, 60-70% of the current research plans use multiple laser radars to perceive the surrounding three-dimensional space...
