Embodiment Construction

[0012] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. see figure 1 , the steps of the embodiment include:

[0013] S11: Detect the human body image in the video image;

[0014] S12: Determine the feature vector of the human body image, and match the determined feature vector with multiple reference vectors in the pre-collected database according to the weights of different colors;

[0015] S13: Taking the successfully matched human body image in the database as the recognition result.

[0016] Through the above steps, the human body image can be determined in the database, and the determined human body image can be used as the detected human body image. Therefore, a unique human body image can be determined among multiple human body images in the video. For foggy conditions, the accuracy of recognition is improved by adding color weights.

[0017] Preferably, in an embodiment, the st...

Abstract

The invention provides a human body reidentification method in foggy days. The method comprises that: detecting human body images in a video image; determining feature vectors of the human body images, and matching the determined feature vectors with multiple basic standard vectors in a data base collected in advance according to weight function of different colors; and using the human body images successfully matched in the data base as an identification result. Through the steps, the human body images can be confirmed in the data base, and the confirmed human body images are used as the detected human body images. Therefore, movement tracks and the activity range of each human body image in a video can be mastered especially in the foggy days. Due to the fact that the foggy days have a weakening effect on colors, human bodies are not easy to distinguish.

Description

technical field [0001] The invention relates to the field of video surveillance, in particular to a method for re-identifying a human body in foggy weather. Background technique [0002] For security in public places, cameras are usually used to collect images. [0003] Due to the current video recognition technology, it can only recognize the human body image in the video, but cannot confirm the individual corresponding to the human body image, which leads to the inability to distinguish the movement trajectory of each person, and cannot determine the corresponding individual of the human body image in the current video. identity. Especially in foggy days, because foggy days have a weakening effect on the color, it is not easy to distinguish. Contents of the invention [0004] The present invention aims to provide a method for human body re-identification in foggy days, so as to solve the problem that the individual of the human body image cannot be confirmed. [0005]...
