Embodiment Construction

[0033] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The present invention provides a kind of mouse trajectory tracking method based on background modeling, it is characterized in that, comprises the following steps:

[0035] S101. Extract data before a specified frame in the original video, and establish 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 to the specified frame, and extracts all the data in...

Abstract

The invention discloses a mouse trajectory tracking method based on background modeling, and relates to the technical field of intelligent video monitoring. The method comprises the following steps: extracting data before a specified frame in an original video, and establishing a background model; creating a blank image as an initialized thermodynamic diagram of a mouse track; performing foreground detection on each frame of image after the specified frame, and extracting target frames of all foreground moving targets in the current frame of image; establishing a Gaussian mixture distributionmodel for the target box; and accumulating the Gaussian mixture distribution model on an initialized thermodynamic diagram to generate a thermodynamic diagram of the moving target, namely the track ofthe mouse. When the mouse track is detected, the mouse track detection method is not limited by kitchen scenes, is easy to implement, high in operation efficiency and convenient to develop and deploy, and can greatly solve the hidden danger problem in the catering industry.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a mouse track tracking method based on background modeling. Background technique [0002] With the development of computer vision technology and the continuous improvement of people's living standards, food safety issues have 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, identification, tracking, etc., and on this basis through pre-set rules ...
