Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention provides a mouse trajectory tracking method based on background modeling, which is characterized by comprising the following steps:

[0035] S101, extracting data before a specified frame in the original video, and establishing a background model. The establishment of the background model can be realized with only one image, but in order to establish a more stable background model, the present invention uses the original video data to start running into a specified frame, and extracts all th...

Abstract

The invention discloses a mouse trajectory tracking method based on background modeling, and relates to the technical field of intelligent video monitoring. It includes the following steps: extracting the data before the specified frame in the original video, and establishing a background model; creating a blank image as the initialization heat map of the mouse trajectory; performing foreground detection for each frame image after the specified frame, and extracting all the images in the current frame image. The target frame of the foreground moving target; establish a mixed Gaussian distribution model for the target frame; accumulate the mixed Gaussian distribution model on the initialization heat map to generate the heat map of the moving target, that is, the mouse's trajectory. When detecting the mouse trajectory, the invention is not limited by the back kitchen scene, is easy to implement, has high operation efficiency, and is convenient for development and deployment, and can greatly solve the hidden troubles in the catering industry.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a mouse trajectory tracking method based on background modeling. Background technique [0002] With the increasing development of computer vision technology and the continuous improvement of people's living standards, food safety issues have also attracted more and more attention. The public's requirements for the catering industry have also increased, and businesses also hope to solve the most important hygiene problems in the food field through computer technology. Intelligent video surveillance technology with intelligent analysis has begun to play a very active role in the catering industry. Intelligent video surveillance technology refers to the use of computer vision analysis methods to automatically analyze video sequences without human intervention to achieve moving target detection, classification, recognition, tracking, etc. The behavior of the tar...
