Problems solved by technology

This invention mainly focuses on the design of the radar, without mentioning specific detection methods, etc. The accuracy of the radar is 10 cm, which is acceptable in applications such as measuring vehicle distance or lane lines, but if the current system is more and more The more highly integrated the trend, the accuracy is obviously unable to meet the demand
In addition, the four-line lidar is a kind of non-imaging radar, and the detected results lack good visualization effects. If only the way of animation is used, the lack of intuitive effect

Abstract

The invention relates to a system for detecting a lane line based on a laser radar and a realization method thereof. The system comprises a control module which is formed by an image processing module and a central processing module. The input end of the image processing module is connected to the output end of a vehicle-borne laser radar. The data output end of the image processing module is connected to the data input end of the central processing module. The output end of the image processing module is connected to the input end of a display module. The input end of the central processing module is connected to the output end of a speed measurement sensing module. The output end of the control module is connected to the input end of an early warning module. According to the system and the method, through the cooperative use of the vehicle-borne laser radar, the image processing module and the central processing module, the condition of a road surface can be detected in different light conditions, the condition of a road surface ahead can be predicted, and the system can play a warning role earlier than a general system.

Description

technical field [0001] The invention relates to a system for detecting lane lines based on laser radar and an implementation method thereof. Background technique [0002] With the vigorous development of the automobile industry, the traffic volume continues to increase, the incidence of traffic accidents also increases, and the pressure on drivers is also increasing. In the past, car safety technology focused more on reducing losses caused by car accidents, such as seat belts, airbags, anti-lock (lock) braking systems, etc. These technologies are called passive safety technologies and cannot prevent effect of the accident. With the development of electronic technology, navigator car radar and other technologies are widely used in the automotive industry to assist driving. This type of technology does not have the ability to automatically control the vehicle in an emergency, but only displays information that the driver is likely to ignore or blind spot information to the d...
