Embodiment 1

[0055] combined with figure 1 , this embodiment proposes a method for tracking and backtracking personnel movement trajectory based on domestic CPU environment, and its implementation includes:

[0056] Step S1. Based on the personnel information and the identifiable face images of the personnel, a personnel feature database is established.

[0057] Personnel information includes required information and optional information, among which:

[0058] Necessary information includes the name of the person and the ID number of the person.

[0059]Optional information includes age, gender, home address, work unit, personnel number, and hobbies.

[0060] After storing the necessary information and the identifiable face image of the person in the person feature database, the unique ID of the person will be generated in the person feature database as the retrieval index and unique identification of the person.

[0061] Step S2, based on the actual spatial layout of the park, use HTML...

Embodiment 2

[0072] combined with figure 2 , the present embodiment proposes a system based on domestic CPU environment to track and trace personnel movement trajectory, and its implementation structure includes: acquisition building module 1, drawing module 2, camera module 3, image comparison module 4, acquisition and drawing module 5, storage module 6. Trajectory backtracking module7.

[0073] The collection building block 1 is used to collect personnel information and identifiable facial images of personnel, and then establish a personnel feature library based on the collected information. Personnel information includes necessary information and optional information, among which: necessary information includes personnel name and personnel ID number; optional information includes personnel age, gender, home address, work unit, personnel number, hobbies; After the recognized face image is stored in the personnel feature database, the unique ID of the person will be generated in the per...

Abstract

The invention discloses a method and a system for tracking and backtracking a personnel motion trajectory based on a domestic CPU environment, and relates to the technical field of trajectory tracking, and the implementation content comprises the following steps: S1, based on personnel information and personnel recognizable face images, establishing a personnel feature library; s2, drawing a park schematic diagram based on the actual spatial layout of the park; s3, acquiring face images of the personnel through a plurality of cameras in the park, and comparing the face images with identifiable face images of the personnel in the personnel feature library to realize personnel identity identification; s4, drawing a movement track of the person in the park based on an identity recognition result of the same person by the plurality of cameras in the S3; and S5, storing the movement tracks of all personnel in the park in a database according to a naming format of'personnel name + time ', and retrieving and backtracking the corresponding movement track in the database by inputting the personnel name and the starting time point. According to the invention, the complexity of a conventional trajectory tracking backtracking algorithm is simplified, and the pressure of a domestic server is reduced.

Description

technical field [0001] The present invention relates to the technical field of trajectory tracking, in particular to a method and system for tracking and retracing personnel movement trajectory based on a domestic CPU environment. Background technique [0002] In recent years, with the rapid development of artificial intelligence, face recognition technology has been widely used in the field of security monitoring. With the popularization of broadband, the development of computer technology, and the improvement of image processing technology, video surveillance is penetrating into education, government, entertainment, medical care, hotels, sports and other fields more and more widely. [0003] However, most of the traditional video surveillance systems can only provide functions such as switching between multiple cameras and pan-tilts, recording, playback, and processing of images through the control host. [0004] With the introduction of more personalized requirements suc...
