Embodiment

[0148] The following is an experiment of tracking a moving five-pointed star-shaped moving target. It uses the MPEG4 format introduced earlier and the tracking and recording method of a single moving target track to track and record the five-pointed star-shaped moving target. The software uses Visual C++ 6.0 as the development platform. The program uses the VFW software package provided by Microsoft to process the captured video data according to the process of extracting the contour of a single moving target, performing template matching on the contour of a single moving target and recording the motion track, and respectively Use the MPEG4 format and the tracking and recording method of a single moving target track to record.

[0149] Referring to FIG. 4 , what this figure shows is a screenshot of recording in MPEG4 format and extracting the outline of the target. We can see from the figure that although the MPEG4 format can provide better visual effects, it is not very impor...

Abstract

The invention discloses a tracking and recording method for a single moving target track by adopting a computer program, which aims to overcome the problem that the tracking and recording of a moving target track occupies large storage space. The method adopts the steps of installing a hardware system, extracting a target contour, making template matching and track recording to the target contour. Extracting a target contour is to adopt a tth frame image, a (t-1)th frame image and a (t+1)th frame image of a target video; the steps such as three-frame differencing operation, 'AND' operation, median value filtering and extracting an actual contour and so on, are made. Making template matching and track recording to the target contour adopts to find the centroid position of a target and store the centroid position; the stored information of the centroid position is made a distance transformation and is matched with Hausdorff distance; the actual shape of the target is stored; then the (t+1)th frame image is extracted, the steps such as matching and storage and so on, are made according to the flow of extracting the target contour and the method of making template matching and track recording to the target contour; the steps are circularly made.

Description

technical field [0001] The invention relates to a tracking technology of a moving target and its moving track in the field of computer vision, more precisely, it relates to a tracking and recording method of a single moving target track. Background technique [0002] The detection and tracking of moving targets is one of the core topics in the field of computer vision. It integrates the research results of image processing, pattern recognition, artificial intelligence and other related fields. , meteorological analysis, intelligent transportation and many other fields have a wide range of applications. [0003] In the intelligent traffic management system, the real-time detection and tracking technology of the vehicle is one of the important technologies of the intelligent traffic system. The computer realizes the detection and tracking of the vehicle by analyzing the video sequence recorded by the camera without human intervention or with little intervention. On this basi...
