Abstract

The invention relates to an intelligent image compression device combined with a television tracker, wherein a first digital signal processor of the device reads images in an image storing device to perform object acquisition tracking; the first digital signal processor stores the images in an object area and the size and the position of an object in an object storage area through a programmable logic array, fills the object area of real-time images, and stores the filled images into a background storage area as images in a background area; and a second digital signal processor reads the images in the object area and the images in the background area by programmable logic array, and compresses and codes the images in the object area and the images in the background area respectively; and code stream data is output through a communication terminal. The intelligent image compression device can code the images in the object area and the images in the background area respectively while performing real-time tracking on the object, thus the compression ratio is improved as much as possible on the premise of ensuring the image quality of the tracking object, and the storage space of the images and the network transmission bandwidth are effectively reduced.

Description

technical field [0001] The invention relates to a TV tracker, in particular to an intelligent image compression method combined with the tracker. Background technique [0002] The TV tracker is a system that uses photoelectric imaging technology to track various targets within the working range of the tracker. The improvement of the algorithm and the proposal of a new algorithm are used in the software, and the development and replacement of the high-speed digital signal processor are used in the hardware. , so that not only the detection, extraction, recognition and tracking of targets can be carried out under real-time conditions, but also the parameters of each target can be accurately calculated. [0003] With the continuous improvement of digital signal processor (DSP) chip integration, computing speed, data throughput and other performance, DSP has been widely used in the field of real-time image processing. [0004] Chinese Patent Gazette discloses an "image recognit...
