Target image real time transmission and tracking method based on digital signal processor (DSP) and target image real time transmission and tracking device based on digital signal processor (DSP)

Abstract

The invention discloses a target image real time transmission and tracking method based on a digital signal processor (DSP) and a target image real time transmission and tracking device based on the DSP. A method of an image tracking part combines a connected domain algorithm with a template matching algorithm, and the connected domain algorithm is used to obtain a target to be tracked, establishes an image template of a target object, and uses the template matching method to track the target. A target movement track predicted by using a least square method is combined to search the target in a wave gate. If the template matching method fails to track, the connected domain algorithm is used to capture the target again, and the connected domain algorithm establishes the image template again and continues to track till the tacking is finished. The target image real time transmission and tracking device based on the DSP comprises an image processing unit, a sighting telescope, a servo system, a switchboard, a remote terminal and an integrated management personal computer (PC). The target image real time transmission and tracking method based on the DSP and the target image real time transmission and tracking device based on the DSP are capable of tracking a moving target and transmitting the tracking process to an Ethernet network, a user on the network can remote control the tracking process of the target, and the integrated management PC can further change the target to be tracked and switch a tracking mode.

Description

technical field [0001] The invention belongs to an image processing and image transmission technology, in particular to a DSP-based target image real-time transmission and tracking method and device thereof. Background technique [0002] A general image tracking system uses a camera as an imaging sensor and uses an image tracker to generate a tracking error signal as a photoelectric tracking device. The image tracking system is mainly composed of four parts: camera, image tracker, servo system and monitor. The camera is a key part of the image tracking system. It is used to capture the image of the scene (including the target), and convert the optical image into a video signal that conforms to the TV standard. Generally, a CCD camera, an infrared imager, a laser camera, etc. are used. The image tracker is the core part of the entire image tracking system. Its main function is to process the collected images, including image preprocessing, image recognition (image segmentati...

Problems solved by technology

[0004] The existing technology systems generally can only automatically select the tracking target, and cannot manually select the tracking target; generally use a single connected domain algorithm or template matching algorithm, and do not combine the two algorithms; the system generally does not have an Ethernet transmission function
