Embodiment Construction

[0092] The present invention will be further described below in conjunction with the accompanying drawings.

[0093] refer to Figure 1-12 , a multi-target object tracking system for panoramic video sequence images, including an omnidirectional camera device for acquiring a large-scale scene, a microprocessor for underlying conceptual processing of the panoramic images captured by the omnidirectional camera device, and a system for A PC that performs formal processing and behavior semantic processing on the underlying conceptual processing results. The panoramic vision processing flow is as follows: figure 1 As shown, the system hardware structure is as follows figure 2 shown; the omni-directional camera device, such as image 3 As shown, referred to as ODVS, it is placed above the middle of the monitoring scene, so that ODVS can capture the panoramic video image of the target object in the entire scene. The captured panoramic image is as follows Figure 4 A circle as show...

Abstract

A multi-target object tracking system of a panorama video sequence image comprises a panorama camera shooting device and a microprocessor. The panorama camera shooting device is used for acquiring a scene in a large area, and the microprocessor is used for video analyzing and processing a panorama image shot by the panorama camera shooting device. During the processing process of moving target object extracting and simple multi-target object tracking, an MHoEI (motion history or energy images) algorithm which is low in computation complexity, simple in parameters and threshold value selection and convenient to realize in a system-on-chip is utilized. In order to effectively track multi-target objects in the scene in cases of shielding, separating and merging, the multi-target objects are sequentially tracked via motion characteristics, color characteristics and shape characteristics of the target objects according to matched results, and while tracking efficiency is improved, robustness for tracking the multi-target objects is improved.

Description

technical field [0001] The invention relates to the application basic technology of technologies such as computer vision and omnidirectional vision in panoramic intelligent video analysis, and in particular to a multi-target object tracking system in panoramic video sequence images. Background technique [0002] Target object tracking is the premise of the analysis and recognition of target object behavior, and it plays an extremely important role in intelligent video analysis. Target object tracking is to construct a target object matching problem based on attributes such as shape, size, position, motion direction, speed, color, texture, etc. by analyzing the dynamic image sequence captured by the camera. [0003] A highly robust target object detection system needs to have graphics processing functions such as motion detection, shadow and noise elimination, etc. At present, various parameters need to be adjusted in advance to realize the above functions. However, the exis...
