Problems solved by technology

[0002] The photoelectric tracking system is widely used in imaging-guided weapon systems and fire control systems. It has the characteristics of good concealment and strong anti-electromagnetic interference. It plays a vital role, and its miss-target output data rate determines the tracking performance of the photoelectric tracking system, such as tracking accuracy, maximum tracking speed, and transition characteristics; but due to the limitation of photoelectric imaging devices, most of the current ordinary cameras use In the CCIR system, the field frequency is 50Hz, and the output data rate of the target miss amount of the video tracking system based on this camera is also 50Hz; and the high field frequency camera is also quite expensive in addition to the disadvantages of low sensitivity.

Embodiment 1

[0019] Such as figure 1 As shown, the front objective lens I receives external parallel light to obtain parallel light A, and parallel light A passes through a half mirror II installed at an angle of 45° to obtain two identical parallel light B and parallel light C, wherein parallel light C is refraction The parallel light is projected onto the target surface of the camera 1 after being converged by the first mirror group III. The parallel light B is reflected parallel light, and the parallel light D is obtained through a total reflection mirror IV installed at an angle of 45° with it. The parallel light D is converged by the second mirror group V and projected onto the target surface of the camera 2; the camera 1 and the camera 2 are two cameras with the same technical index, and the scene signal is converted into a video signal It is required to ensure that the optical axes of the two cameras are parallel to each other when the system is installed and adjusted.

Embodiment 2

[0026] The difference from Example 1 is:

[0027] The camera is: a camera that works in an internal synchronous mode, separates a synchronous signal from its output video signal, and generates a synchronous signal based on this to synchronize another video camera that works in an external synchronous mode ;Such as Figure 4 As shown, an internal synchronous camera 1 and an external synchronous camera 2 can be used; as shown in 5, an external synchronous camera 1 and an internal synchronous camera 2 can also be used.

Abstract

The present invention discloses one kind of method and device for raising the data rate of video tracking system. The video tracking method is that the outer scene is first formed into one parallel light beam through the front objective, the parallel light beam is then formed into one refracted parallel light beam and one reflected parallel light beam in the 45 deg half-reflecting mirror, the refracted parallel light beam is converged to the target plane of the first video camera, the reflected parallel light beam is reflected with one holophote and converged to the target plane of the second video camera; these two video cameras are synchronous and have the same field period but a phase difference of half a field period; the video signals from these two video cameras are processed in the video tracker to obtain the target-missing quantities; and the target-missing quantities are fed to the servo system to complete the tracking to the target. The video tracking system obtains one time raised data rate and has raised tracking performance.

Description

technical field [0001] The invention belongs to the construction technology of photoelectric tracking equipment, specifically a method for increasing the data rate of a video tracking system and the device used. The video tracking system constructed by this method can obtain twice the output data rate of the target miss amount, so as to improve tracking System tracking performance purposes. Background technique [0002] The photoelectric tracking system is widely used in imaging-guided weapon systems and fire control systems. It has the characteristics of good concealment and strong anti-electromagnetic interference ability. It plays a vital role, and its miss-target output data rate determines the tracking performance of the photoelectric tracking system, such as tracking accuracy, maximum tracking speed, and transition characteristics; but due to the limitation of photoelectric imaging devices, most of the current ordinary cameras use In the CCIR system, the field frequen...
