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 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 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 camera with high field frequency has the disadvantages of low sensitivity, and the price is also quite expensive

Embodiment 1

[0017] Such as figure 1 As shown, the front objective lens I receives the first parallel light from the outside world to obtain parallel light A, and the first parallel light A passes through a half mirror II installed at an angle of 45° to obtain two identical second parallel light B and third parallel light C, wherein the third parallel light C is a refracted parallel light, which is projected onto the target surface of the first camera 1 after being converged by the first mirror group III, and the second parallel light B is a reflected parallel light, which forms a 45° angle with it through a The total reflection mirror IV installed at an angle obtains parallel light D, and the parallel light D is projected onto the target surface of the second camera 2 after being converged by the second mirror group V; the first camera 1 and the second camera 2 are two sets with the same technical index The camera completes the function of converting the scene signal into a video signal, ...

Embodiment 2

[0024] The difference from Example 1 is:

[0025] Described video camera is: a video camera that works in internal synchronous mode, separates synchronous signal from the video signal of its output, on the basis of this, generates synchronous signal synchronously to another video camera that works in non-synchronous mode; Figure 4 As shown, the first camera 1 for internal synchronization can be used for external synchronization of the second camera 2; as shown in 5, the first camera 1 for external synchronization can also be used for the second camera 2 to be internally synchronized.

Abstract

The invention discloses a method and a device used for increasing the data rate of a video tracking system. The method is: the external scene first passes through the front objective lens to form a beam of parallel light, and then the parallel light passes through a half-reflection mirror installed at an angle of 45° to obtain the other two paths of the same refracted parallel light and reflected parallel light, wherein the refracted parallel light The light is converged and projected onto the target surface of the camera through the mirror group, and the reflected parallel light is reflected by a total reflection mirror installed at an angle of 45° with it, and then converged and projected onto the target surface of the camera through the mirror group; The synchronization timing of two cameras differs by half a field cycle, and the field cycle is the same; the video signals output by them are processed by the video tracker to obtain the target miss amount, and the output miss target amount of the video tracker is sent to the servo system to complete the tracking of the target . The video tracking system constructed by the invention can obtain twice the output data rate of the target miss amount, so as to achieve the purpose of improving the tracking performance of the tracking system.

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 the CCIR system , its field frequency...
