Apparatus and method detectinc obstacle and alerting collision

Abstract

The invention relates to an apparatus and a method detecting an obstacle and alerting collision. Based on an identification value of a vehicle position, a sensing value of the obstacle and image data from a camera, the apparatus, after detecting the obstacle, detects the short-distance and long-distance obstacle movement in real time accurately and notifies the driver of the detection result by using a machine learning method. According to the invention, based on principal component analysis and obstacle image characteristic value, the performance of obstacle detection is improved greatly, the obstacle can be detected automatically, movement of the obstacle can be detected and the driver can be notified through alarm, so the driver needs not to operate the vehicle additionally and convenience is provided; feature factors of data are extracted and are classified through machine learning algorithm, so that the complexity is reduced; and, based on the sensor and the obstacle image information, different obstacles can be detected accurately through lighting or posture and an alarm can be given, so that the danger of collision between the vehicle and the moving obstacle can be reduced and the errors in the prior art can be reduced greatly.

Description

technical field [0001] The invention relates to an obstacle detection and collision alarm device and method thereof, in particular to an obstacle detection and collision alarm device and method during parking. Background technique [0002] Such as figure 1 As shown, the existing automatic parking system includes an automatic position recognition unit, a parking space judgment unit, a parking route generation unit, a parking route tracking unit and a system management unit. [0003] The automatic position recognition unit receives vehicle information (such as steering angle (Steering Angle), wheel pulse (Wheel Pulse), yaw rate (Yaw rate), temperature (Temperature), etc.) to determine the state and position of the vehicle, and transmits it to the trajectory calculation / control module. [0004] The parking space judging part uses the information received from the sensor to judge the parking space, calculates the parking target point of the vehicle, and sends it to the parkin...

AI Technical Summary

Problems solved by technology

When the parking vehicle located on the left and right sides of the parking vehicle is very complicated or the parking space required to pass through the obstacle is narrow, if the driver is not informed of the location of the active obstacle, then the parking vehicle cannot communicate with the surrounding obstacles. Maintain a predetermined distance, even if the movement of obstacles is detected in real time, the risk of collision with obstacles is still high

[0026] In addition, in the case of sensing an obstacle behind and alerting the driver, the driver only uses the image of the camera to recognize the obstacle. Therefore, the obstacle recognition rate decreases at night or in bad weather such as heavy fog, and a collision may also occur. situation
