Embodiment Construction

[0019] Such as figure 1 As shown, a multi-target dynamic tracking method based on a ball-borne platform includes a manual frame selection target tracking method and an automatic detection and tracking method. If the warning area is selected to draw a snapshot warning and the video is saved in real time during the tracking process, the described The warning area drawing capture warning is to draw a warning area on the image of the high-altitude dome camera monitoring scene in advance, and all tracking targets passing through the warning area will be captured and warned;

[0020] (1) if figure 2 As shown, the manual frame selection target tracking method uses an efficient tracking algorithm to select the moving target of interest from the image transmitted by the high-altitude ball camera in real time for tracking. The manual frame selection target tracking method requires real-time tracking Robustness and background shaking, and if the tracking target enters the drawn warning...

Abstract

The invention discloses a multi-target dynamic following method based on a balloon platform. The multi-target dynamic following method comprises a manual frame selection target following method, and an automatic detection following method; according to the manual frame selection target following method, a following target is manually marked on a balloon platform video and is then followed; the compression dimensionality reduction method is adopted to perform dimensionality reduction on the characteristics of the foreground target and the background through the compression dimensionality reduction theory to obtain the positive sample and negative sample of an on-line study update categorizer; then the training categorizer is adopted to predict the target position of the image of the next frame; according to the automatic detection following method, an initialization detection zone is manually set on an image downloaded from a high-altitude balloon camera, and movement target in the designated zone is detected in a real-time manner; detected movement target is marked; the same on-line study following method is adopted for following. The multi-target dynamic following method can effectively overcome the following problem caused by vibration of balloon video vibration while following real-time performance and certain degree of accuracy are ensured.

Description

technical field [0001] The invention relates to the field of moving target detection and tracking, in particular to a multi-target dynamic tracking method based on a ball-borne platform. Background technique [0002] Ball-borne platform floating air balloons belong to the category of aviation products. It can be equipped with different electronic equipment to perform specific tasks. It has the advantages of long space time, large load capacity, good safety, and low operating cost. It has the advantages that other platforms such as aircraft and satellites cannot replace. Disaster reduction and remote sensing, radio and television, surveying and mapping and other fields have broad application prospects, and are the focus and hot spot that countries around the world are competing to develop. According to CCTV reports, Russia is developing a giant airship, and my country has also listed it as one of the 17 major scientific and technological projects one. [0003] At present, the...
