Vehicle surveillance system and method thereof

Abstract

The present invention relates to a vehicle monitoring system and a method thereof for monitoring the position and the distance of at least one monitored object surrounding a vehicle through an eagle view system. The vehicle surveillance system includes a plurality of image capturing units, an image processing unit, and a display unit for monitoring a position of at least one target around a vehicle and measuring a distance between the at least one target and the vehicle. The vehicle surveillance system utilizes a space domain determination module, a time domain determination module, and a ground surface elimination module to transform original images of the target around the vehicle into the eagle view panorama, and further detects variation of an optical pattern incident onto the target through a light beam emitted by a light source so as to effectively remind a driver on the on-going vehicle of the position of the target and the distance, and real-time detect and capture an image of any person approaching the vehicle, thereby achieving driving safety and securing lives and personal properties.

Description

technical field [0001] The present invention relates to a vehicle monitoring system and its method, in particular to a vehicle detection system that uses a panoramic bird's-eye view image overlooking the vehicle and an optical pattern projected by a light source to display the existence and distance of the monitored object and its method.

[0002] By the way, in today's society, mobile vehicles have become an indispensable means of transportation for Chinese people. Whether it is tourism, passenger transportation or freight transportation, etc., they all rely heavily on the help of mobile vehicles; , Accidentally enter a dead-end or narrow alley and cannot move, or some bulky vehicles must reverse or turn around in crowded places due to factors such as bad weather or blind spots. Accurately knowing the real situation around the vehicle results in many accidents of varying severity; therefore, there are currently many solutions to install video capture devices such as video cameras or cameras around the mobile vehicle to solve the above problems; however, traditional video There are still many blind spots when the device is used in the monitoring of vehicle safety, and there is a need for further improvement; in order to solve the above-mentioned problem of blind spots, many studies use multiple cameras set around the vehicle to combine the acquired images into a bird's-eye view The method of imaging, such as the "vehicle image security system" of Taiwan Patent No. M479253, takes this as the starting point. This patent mainly installs multiple camera modules around the vehicle, and then captures the camera modules through a central control module. Combining images of the above and generating a bird's-eye view image to warn drivers of driving safety; however, this patent does not clearly explain how the image is converted into a bird's-eye view image, and how to capture the image of obstacles in the bird's-eye view image

[0003] In addition, the anti-theft device used in general vehicles sends out a loud alarm sound when the vehicle is shaken or the door is opened, so as to remind drivers or passers-by, and to deter criminals; however, traditional anti-theft devices cannot effectively conduct instant search. When the vehicle is parked on the side of the road and is damaged by gangsters, even if the anti-theft device sounds an alarm, if the owner cannot arrive at the scene to stop it in time, he will not be able to effectively know the appearance of the gangster; therefore, how to effectively use the hardware The design can accurately and comprehensively detect the position and distance of the monitored objects around the vehicle while the vehicle is moving, and immediately detect unknown people approaching when the vehicle stops, so as to warn the driver to pay attention to driving safety and protect life and property. Issues that developers and researchers in related industries such as vehicle detection systems need to continue to work hard to overcome and solve
