Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] see figure 1 , figure 1 It is a flowchart of a moving target recognition method, and the moving target recognition method includes the following steps:

[0030] S101, according to the obtained color difference between the pixel block where each pixel is located in the current frame image and the surrounding pixel blocks, and the distance between the pixel block where the pixel is located and the surrounding pixel blocks, calculate the color and distance difference of each pixel measure value.

[0031] There are often color differences between moving target pixels and background pixels, su...

Abstract

The invention relates to a moving object recognition method, an early-warning method and an automobile rear-end collision prevention early-warning device. The moving object recognition method includesthe steps of calculating a difference measurement value of the color and the distance of each pixel according to the color difference between the pixel blocks of each pixel in an acquired frame imageand the surrounding pixel blocks and the distance between the pixel blocks and the surrounding pixel blocks, calculating a plurality of reference difference measurement values of each pixel by takinga plurality of pixel blocks with the difference measurement value smaller than the difference measurement threshold value as reference, obtaining a remarkable characteristic value of each pixel, obtaining a color and distance significant information graph according to the pixels with the obvious characteristic value larger than the characteristic threshold value and the remarkable characteristicvalues of the pixels, determining the motion characteristic image by utilizing the continuous multi-frame color and the distance significant information diagram, and determining the moving target in acurrent frame image. According to the moving object recognition method, a target can be accurately and efficiently recognized from a frame image by combining color difference of the target and the background, larger similarity probability with closer the pixel blocks and target motion characteristics.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a moving target recognition method, an early warning method and an automobile rear-end collision prevention early warning device. Background technique [0002] Target recognition technology based on image feature information extraction has a wide range of applications in various fields. Target recognition technology can use image analysis methods to extract and recognize targets in images. For example, in terms of safety monitoring and early warning, especially in the field of car anti-rear collision warning, video monitoring of vehicles, pedestrians and other information in the front and rear of the car can be used to extract the target and predict the movement state of the target, and issue an early warning when the target may collide with the rear , which requires that the moving target recognition method used in the video target recognition has a high degree of real-...
