Abstract

The invention discloses a filtering and denoising method applied to edge detection, which comprises the following steps of: analyzing pictures of pedestrians, vehicles and obstacles on a road shot bya forward-looking camera, respectively filtering and denoising three spatial components of a color image by adopting a wavelet threshold algorithm, and graying the three recombined components by adopting a weighted average method; processing an image by adopting top hat transformation and multiple edge detection methods, and extracting edge features, so the image quality is effectively improved, and the influence of the problem of non-uniform light on recognition is weakened. The filtering and denoising method applied to edge detection provided by the invention performs edge detection on targets such as pedestrians and vehicles on a road with high efficiency and high precision, solves the influence of noise and uneven illumination on image edge detection, improves the detection precision of edge detection, provides a basis for subsequent target identification work, and is remarkable in action effect and suitable for wide popularization.

Description

technical field [0001] The present invention relates to the technical field of edge detection, in particular to a filtering and denoising method applied to edge detection. Background technique [0002] The front-view camera is usually installed behind the front windshield, and the front-view camera can obtain various traffic target information such as vehicles in front, passing vehicles, pedestrians in front, traffic signs, and lane lines. The image information acquired by the front-view camera is recognized and processed by the chip. The boundary between the background of the image and the target image is the edge of the image. [0003] At present, during the image collection process of the front-view camera, due to the influence of the electronic components and electronic circuits of the camera itself, the collected pictures will be noisy, which will affect the detection and recognition results. Due to the variable factors of environmental lighting conditions, the illumi...
