Embodiment 1

[0071] This embodiment provides a personnel search method, such as figure 1 shown, including the following steps:

[0072] S1. Receive an image containing a person to be searched; the image may come from the Internet, mobile phone, historical query images, etc.

[0073] S2. Segment the image to obtain the whole body region of the person, or the upper body region or the lower body region of the person, or all the body region, upper body region and lower body region of the person.

[0074] S3. Separately extract various types of feature information of the person's whole body region, the person's upper body region and / or the person's lower body region. Preferably, if one or more regions of the person's whole body region, the person's upper body region and the person's lower body region are obtained in step S2, multiple types of feature information of the image in the region are correspondingly extracted. Regions that are not obtained in step S2 are not extracted, and cannot be ...

Embodiment 2

[0123] Corresponding to Embodiment 1, this embodiment provides a personnel search device, such as figure 2 shown, including:

[0124] A receiving unit 1, configured to receive an image containing a person to be searched;

[0125] Segmentation unit 2, configured to perform segmentation processing on the image to obtain a person's whole body region, a person's upper body region and / or a person's lower body region;

[0126] The feature extraction unit 3 is used to extract various types of feature information of the person's whole body region, the person's upper body region and / or the person's lower body region;

[0127] The first calculation unit 4 is used to separately calculate the similarity between each type of feature information of each area and the corresponding feature information in the database, and the database is used to store a variety of images including images in the whole body area of ​​the person corresponding to all the person images. Types of feature informa...

Embodiment 3

[0152] This embodiment provides a personnel search system, such as image 3 As shown, it includes a camera 10 and a processor 20 deployed at multiple points;

[0153] Camera 10 is used to collect images containing people (pedestrians, etc.) in real time. For example, the camera has the function of intelligent capture, which can automatically extract the pedestrians in the surveillance video, and obtain the pictures of pedestrians that are deducted; the images collected in real time are sent to the processor;

[0154] A processor 20, including a real-time processing device 201 and a personnel search device 202;

[0155] The real-time processing device 201 is used to receive the real-time captured image sent by the camera; perform segmentation processing on the image to obtain the whole body region, the upper body region and the lower body region of the person; extract the whole body region, the upper body region and the lower body region of the person respectively Various typ...

Abstract

The present invention discloses a person searching method, apparatus and system. The method comprises: receiving an image that contains a to-be-searched person; performing segmentation processing on the image, so as to obtain a person whole-body region, a person upper-body region and / or a person lower-body region; separately extracting various types of feature information of images in the person whole-body region., the person upper-body region and / or the person lower-body region; separately calculating a similarity degree between each type of feature information of each region and corresponding feature information in a database; performing a weighted operation according to a preset weight value of the similarity degree, so as to obtain a fusion similarity degree of images in the person whole-body region, the person upper-body region and / or the lower-body region that correspond to each person image in the database; and separately obtaining searching results of person images, which is sorted according to the fusion similarity degree, in the database. The method, apparatus and system disclosed by the present invention have the advantages of an accurate retrieval result and high retrieval efficiency.

Description

technical field [0001] The invention relates to the fields of picture search and video surveillance, and in particular to a personnel search method, device and system. Background technique [0002] With the extensive construction of safe cities and the popularity of surveillance in various places, the amount of video surveillance data has become larger and larger, which has brought great challenges to criminal investigation and detection. How to quickly and accurately extract target suspects from these massive databases become the key to solve the case. [0003] The traditional video investigation mode of manual browsing requires a lot of manpower and time, and it is easy to delay the time to solve the case. Personnel search technology facilitates video investigators to quickly and accurately discover the moving pictures and trajectories of suspected targets, which is of great significance for the public security department to improve the detection rate and maintain the saf...
