Abstract

The invention belongs to the technical field of image processing, and relates to a multi-source target tracking measurement system and tracking method based on active vision. The system comprises a photoelectric assembly and a stable platform, wherein the photoelectric assembly is composed of a visible light camera, an infrared thermal imager, a laser range finder, an information processor and a photoelectric cabin structure; the visible light camera, the infrared thermal imager, the laser range finder and the information processor are all installed inside the photoelectric cabin structure; the stable platform consists of an orientation motion assembly, a pitching motion assembly and a control assembly; and the control assembly receives an instruction sent by the information processor, andcontrols the orientation motion assembly and the pitching motion assembly to enable visual axes to stably point to a target. The invention further provides the multi-source target tracking method based on the active vision. The orientation motion assembly and the pitching motion assembly are driven to rotate according to the control instruction, so that the visual axis of the visible light cameraand the visual axis of the infrared thermal imager point to the target, and the target is always kept in the center of a shot image.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an active vision-based multi-source target tracking measurement system and a method for measuring and tracking targets. Background technique [0002] At present, image-based target tracking and measurement technology is more and more widely used, and the mutual verification and fusion of different source data has become an effective method to meet the requirements of stable tracking and measurement in all-weather and complex background scenes. [0003] With the advancement of science and technology, aircrafts play an increasingly important role in our lives, and with it, there are more and more demands for aircraft tracking and measurement. For example, the monitoring and measurement of aircraft takeoff and landing in the airport, the tracking of consumer drones that have emerged in recent years, and the tracking of missile seekers to targets and other application scenario...
