Abstract

The invention discloses a video objective generating device, including a main control module, performing information interaction with a host computer through a serial communication interface, initializing a video signal generating module through a data bus, and appointing an operating status for the target information overlaying module; a video signal generating module, outputting video signal components in different formats, and then taking the video signal components as the input of the target information overlaying module, after a driver circuit amplifying the video signal components and increasing its drive capability; a target information overlaying module, composed of a field-programmable logic gate array and a video overlaying module. The field-programmable logic gate array takes the line field blanking signal or a synchronizing signal as the time sequence base, and generates target information and transmits to the video overlaying module; the video overlaying module receives the composite synchronizing signal, and then generates a target; the generated target video information is taken as the video input of the device to be detected. The use of this system is conducive to the development, with a lower cost; and the invention can be used as a general-purpose module which is widely used in a variety of video systems required to generate simulated targets.

Description

technical field [0001] The invention relates to a video object generation technology, in particular to a video object generation device. Background technique [0002] Object tracking is one of the hotter fields in image processing technology. In recent years, various target tracking technologies have emerged in an endless stream, and these new technologies have been effectively applied to several video processing systems. Generally speaking, the tracker of the video processing system takes the input video image (including TV image, infrared image, etc.) as the target extraction medium and tracks it. For a video processing system, an effective way to test its performance in the early stage of development is to use a target generator to generate a video containing target information as input, mark the status of target tracking, and output the tracking result. In order to facilitate system development, a simple and easy-to-use pre-tracking performance test module should be ad...
