Anti-collision prediction method and system of laser radar detection target

Abstract

The invention discloses an anti-collision prediction method and system for a laser radar detection target, and belongs to the technical field of laser radar detection target anti-collision. Comprising the following steps: in target position data obtained by continuously scanning omnibearing laser radar pulses, if a group of adjacent target position data is approximately close to each other, and the target position data is approximately close to the same straight line through fuzzy logic operation, judging that the group of adjacent target position data belongs to the same target object; different target objects and contours and speeds of the target objects are recognized, and according to the speed and the contour of the moving object where the laser radar is located, whether the moving object collides with the target objects at the time t is calculated. Aiming at the technical problem of low accuracy in target tracking and collision avoidance, the method only depends on the scanning detection function of the laser radar, does not need excessive sensing devices, reduces the operation performance requirements of the devices, can accurately carry out collision avoidance prediction, is high in accuracy, reduces the use amount of the devices, and is low in cost.

Description

technical field [0001] The invention relates to the technical field of laser radar detection target collision avoidance, in particular to a laser radar detection target collision avoidance prediction method and system. Background technique [0002] The technology of automobile anti-collision has had many developments so far, and it is not difficult to find the target and determine its position and distance. However, it is difficult to track because there are many targets around, and it is very cumbersome to grasp all of their dynamics. It is necessary to process a large amount of data, including identifying whether the same target is the same, and the time allowed for processing is very limited. The automatic collision avoidance system (automaticcollision avoidance system) is a part of the smart car. The car anti-collision system is an intelligent device that prevents cars from colliding. It can automatically detect vehicles, pedestrians, or other obstacles that may collid...

Problems solved by technology

[0004] In the prior art, multiple different types of sensors are often used to detect various types of parameter values ​​during the driving process of the car, and perform operations such as processing, calculation, and prediction, so as to guide the car to drive and prevent collisions. The method of obstacle avoidance and collision avoidance has the following technical problems: the number and types of detection and sensor devices used are large, the performance requirements for device response speed are high, and the performance requirements for devices responsible for processing, calculation and prediction operations are also high. , resulting in high cost, which limits market promotion and application

However, the road conditions in the driving process of the car are often complex, and the number of potential collision targets is also huge. The technical solution of the above patent may be limited when used in real scenes.
