Obstacle detection system and obstacle detection method thereof

Abstract

The invention discloses an obstacle detection system and an obstacle detection method thereof. The system comprises an object detection module, a camera shooting module, a calculation module and an object searching module, wherein the object detection module is used for detecting at least one distance and one direction of at least one obstacle within a range of an outside environment, the camera shooting module captures a camera image containing an image corresponding to the obstacle within the range, the calculation module calculates a first area of the obstacle in the camera image according to the detected distance and the detected direction of the obstacle, the object searching module implements first image processing in the first area to search the position of the obstacle and obtain the image of the obstacle, and if the position of the obstacle can not be searched, the calculation module calculates a second area again according to the distance and the direction and implements second image processing in the second area to search the position of the obstacle and obtain the image of the obstacle. By the aid of the obstacle detection system and the obstacle detection method, a driver can know changes of the surrounding environment clearly, so that the safety and the convenience during driving can be greatly improved.

Description

technical field [0001] The present invention relates to an obstacle detection system and an obstacle detection method thereof, in particular to a combination of radar, sonar and image technology, which can detect obstacles and take images of the surrounding environment of the vehicle, and An obstacle detection system and an obstacle detection method for marking the position and distance of obstacles in an image. Background technique [0002] Today, with more and more advanced technology, the reversing radar has almost become the basic equipment of the car. Generally, the reversing radar is installed with an ultrasonic sensor at the rear of the car. When there is an obstacle, it will turn back and be received by the ultrasonic sensor, and then a sound warning device installed in the car will be used to remind the driver of the obstacle information, so as to assist the driver to complete the parking process smoothly. [0003] At present, there is a preferred reversing radar o...
