Traffic obstacle avoidance method and system

Abstract

The invention relates to a traffic obstacle avoidance method and a traffic obstacle avoidance system. The method comprises the steps of: emitting invisible light (3) by an invisible light emitter (2)arranged on an object (1); detecting the invisible light by a detector (5) provided on the vehicle (4); and guiding the driving of the vehicle (4) according to the detection result so as to ensure thesafe distance of the vehicle relative to the object (1). The system correspondingly comprises the invisible light emitter, the detector and a guiding device. According to the method and the system, the object can be detected only by detecting invisible light without a complex object recognition algorithm, so that the method and the system are simple and rapid to implement, high in reaction speedand relatively low in cost. Moreover, due to the fact that invisible light is adopted, pedestrians and drivers cannot see the traffic light, extra indication except for normal traffic indication is formed under the condition that the normal traffic order is not affected, and traffic safety is better guaranteed.

Description

technical field [0001] The invention relates to the field of road traffic safety, in particular to a traffic obstacle avoidance method and system for ensuring a safe distance between a vehicle and obstacles such as surrounding vehicles or infrastructure in road traffic to prevent traffic accidents. Background technique [0002] With the rapid development of computer technology, unmanned driving technology has developed rapidly. In unmanned driving technology, sensing devices such as cameras, radars, lidars, etc. are used to sense road conditions such as surrounding vehicles and buildings, and the sensing results are sent to the computer system. Objects are generated and combined with information such as electronic maps for path planning, commanding vehicles to automatically drive on the planned path. At the same time, in non-autonomous ordinary vehicles, there are also some vehicle auxiliary driving systems or warning systems, which prompt or warn the driver by sensing surr...

AI Technical Summary

Problems solved by technology

[0003] However, the sensing and recognition of surrounding vehicles, buildings and other road conditions requires complex algorithms, which require a large amount of calculation and calculation time, and have high requirements for the computing speed and capability of the processor, which increases the System complexity and technical difficulty

At the same time, the cost of high-precision camera devices or laser radars is relatively high.
