Embodiment Construction

[0079] The following is a detailed description of the embodiments of the present invention: this embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation methods and specific operation processes. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.

[0080] An embodiment of the present invention provides a vehicle collision early warning method based on monocular vision. The method acquires driving status data and front view image data in real time, and obtains the closest target distance estimation through the set collision risk area range, and then performs vehicle collision detection. Auxiliary early warning for vehicle collisions that occur during driving.

Abstract

The invention provides a vehicle collision early warning method and system based on monocular vision, and the method comprises the steps: obtaining front view image data and carrying out the target detection of the obtained image data; setting a collision risk area range; filtering a target in the collision risk area to obtain a nearest target distance estimation value, and estimating the time required for the vehicle to collide with the target in combination with the speed information and the acceleration information of a vehicle; and integrating the nearest target distance estimation value and the time estimation value required for the vehicle to collide with the target, and performing auxiliary early warning on the vehicle collision situation possibly occurring in the vehicle driving process. According to the method, accidents such as collision and rear-end collision of the vehicle in the driving process are effectively reduced, a collision early warning prompt can be automaticallygiven according to the driving state of the vehicle and the minimum distance, obtained based on monocular vision detection, of the vehicle / pedestrian in the front driving area, a driver is effectivelyreminded, and the accident occurrence probability is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a vehicle collision warning method and system based on monocular vision.
