Optical signal injection type simulation method

Abstract

The invention discloses an optical signal injection type simulation technology applicable to a photoelectric theodolite, and provides a step-by-step implementation scheme. The step-by-step implementation scheme includes calculating a possible space mapping relationship between the theodolite and a simulated target when the target is tracked by the theodolite according to a motion trail of the simulated target and tracking performance of the theodolite, projecting a corresponding target and a corresponding scene by a target simulator, and creating a target and scene image database after photographing of the theodolite; during simulation testing, measuring and calculating a space mapping relationship between the tracking axis of the theodolite and the target and a relative motion speed, calling a stored target scene image, performing motion blurring effect processing on the image according to the relative speed, and injecting the image into a video collection processor of the theodolite synchronously to achieve optical signal injection type simulation testing of the theodolite. The problem of difficulty in simulation testing of tracking systems of large-diameter tracking-mode photoelectric theodolites is solved. A tracking system is used for measuring a time difference between target time (TN) and collection time of the image, and accordingly, the optical signal injection type simulation technology is achieved. The technology is also applicable to television tracking systems and infrared tracking systems with same working principles, such as television guided weapon, infrared guided weapon and onboard weapon tracking systems and ground weapon tracking systems.

Description

technical field [0001] The simulation method involves various technologies such as image fitting, high-speed image fusion, precise stitching of video images, synchronous injection of video images, and modeling of the spatial mapping relationship between the target and the tracking system. This simulation technology is applicable to the tracking performance simulation test of tracking systems on various platforms, such as vehicle tracking systems and airborne tracking systems. The invention belongs to the simulation test field of photoelectric tracking system. Background technique [0002] For the large-aperture tracking photoelectric theodolite, the tracking speed, tracking acceleration and tracking accuracy are the key indicators of the tracking system. In the laboratory test, due to the long focal length of the system under test, the performance of the projector and the size of the dome screen are restricted by factors such as the performance of the dome screen projection...

AI Technical Summary

Problems solved by technology

There are errors in the prediction, which makes the target track observed by the theodolite oscillate around the planned track, which will reduce the detection accuracy. Therefore, there is no optical signal injection simulation system at home and abroad.
