Problems solved by technology

Traditional methods such as shadow-based vehicle detection can deal with this kind of problem, but in the driving environment, the vehicles may be dense and the weather conditions may be bad. In these cases, the accuracy of traditional methods is not very high.

Embodiment Construction

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detection of common small cars on urban roads is taken as an example. figure 1 (010) is the image Image_edge after edge extraction from step C011 to step C013. Before getting Image_edge, the color image Image was obtained through the on-board camera. exist figure 1 It can be seen that in addition to the horizontal edge of the vehicle, there are many short and fragmented false edges. Since the number of horizontal edges of the car body is large and relatively regular, the horizontal edge is a good feature to express the vehicle. The upper 1 / 3 area of ​​the image is the sky, in order to reduce the amount of calculation, the lower 2 / 3 area of ​​the image is set as the detection area Detection_area. Count the number of horizontal edge pixels on each column of the detection area, and get the following figure 2 The statistical histogram His_hor of the edge pixels in the horizontal direction of the region is shown. Th...

Abstract

The invention relates to a method for detecting vehicles in a driving dead zone based on a vehicle-mounted camera under a driving environment. The satisfactory precision degree can be obtained even under the situation that the vehicles are dense and the weather is not good. The dead zone vehicle detecting method can be widely applied to detecting the vehicles in the driving dead zone under the driving environment, analyzing analogy of pictures and the like. The requirements for the environment and devices of the method are very low, and the application occasions of the method are enlarged.

Description

technical field [0001] The method of the present invention relates to a method for detecting a vehicle in a driving blind spot based on a vehicle-mounted camera in a driving environment, and can obtain a satisfactory degree of accuracy even when the vehicles are relatively dense and the weather condition is bad; the present invention The method can be widely used in the detection of vehicles in the blind spot in the driving environment, and in the similar analysis of pictures, such as: the detection of vehicles in the blind spot of driving, etc.; at the same time, the method has very low requirements on the environment and equipment, which broadens the application occasions . Background technique [0002] In recent years, digital image processing technology has become more and more mature, and the effect of various target detection algorithms is getting better and better. Some edge detection algorithms can also extract the clear outline of the image, which provides a basis ...
