Target simulation method for photoelectric theodolite

Abstract

The target simulating method for photoelectrical theodolite features the simultaneous simulation of the target locus, target characteristic and the background, the simulation results are fed to the target image synthesizing module, and the target image synthesizing module superposes the target image onto the background image based on the results from the target position calculating module, target characteristic calculating module and the background image selecting module to create the complete image. The final image is fed to the TV image processing system, the computer data processing system and tracking control system in the photoelectrical theodolite for the theodolite to track the simulated target. The present invention provides real-time target simulating image, and is suitable for simulation of various kinds of targets with different kinematics characteristics and imaging characteristics.

Description

Technical field [0001] The invention relates to a target simulation method for a photoelectric theodolite, in particular to a target trajectory, target characteristics and background image simulation method. Background technique [0002] A photoelectric theodolite is usually composed of an optical system, a photodetector, a television image processing system, an angle encoder, a computer data processing system and a tracking control system. In the design and development of modern photoelectric theodolite, it generally needs to go through the stages of system design and processing, indoor joint debugging, outfield flight calibration, operator training and actual tasks. In the process of indoor joint debugging, field calibration and operator training, because the actual target image is difficult to obtain, optical static and dynamic targets are generally used to simulate the target to test the performance of the instrument and equipment. [0003] During indoor joint debugging...

Problems solved by technology

The image quality of the target produced by the signal flare is good, but the target is highly maneuverable, and only the visible light detector can extract the target; the target moves very slowly when the balloon target is released, and the target flight does not have an obvious and smooth target trajectory; The target image generated during the test is generally a surface target, which is different from the target image of a missile. The cost of signaling flares or using an aircraft for flight calibration is very high; the use of live ammunition testing is not only costly, but also risky, and the test results are difficult to reproduce.

[0005] In short, the existing various target simulation technologies are difficult to conveniently and completely generate conditions similar to real tasks, and cannot comprehensively and conveniently integrate the performance of key parts such as the TV image processing system, computer data processing system and tracking control system of the testing instrument. , the cycle from the completion of instrument production to formal use is long, and the cost of field calibration and operator training is high
