Dynamic goal simulator

Abstract

The invention relates to a dynamic target simulator. The technical proposal adopted by the invention is as follows: a drift angle rotary bench is arranged on a work top, and the rotation axis of the drift angle rotary bench is in movable fit with a round hole in the work top; a precise turn table is fixed on the drift angle rotary bench; a dynamic target revolving drum is fixed on the precise turn table, and a plurality of target plates are fixed on the circumferential face of the dynamic target revolving drum; a drift mirror is positioned fixedly on the axial line of the drift angle rotary bench, and a first reflector is fixed on the central shaft of the drift angle rotary bench; the light from a light source irradiates the target plates, and the target plates form image on the drift mirror via the reflection of the first reflector. The dynamic target simulator can simulate a dynamic infinite high-accuracy target, provide a forward moving target for the photochronograph detection of an aero camera, and simultaneously realize the drift action of the target, thereby realizing the dynamic resolution detection of the aero camera in the lab, greatly saving development and detection cost, improving work efficiency and shortening the development cycle.

Description

technical field [0001] The invention relates to a dynamic target simulator, in particular to a long-distance target formed with a collimator to simulate ground objects to be photographed by an aerial camera at different flying heights and speeds, and to realize dynamic resolution detection of the aerial camera. Background technique [0002] At present, the detection of the dynamic resolution of the aerial camera is mainly through the method of flying in the external factory, laying targets on the ground, flying on the plane to take images of the ground targets, and returning to the ground by detecting the aerial images taken during the flight. Check the dynamic photography resolution of the aerial camera. This approach has several disadvantages: [0003] 1) The cost is high. The cost of each flight sortie is about tens of thousands of dollars, and at least a few or even a dozen sorties are required for one inspection, which will inevitably greatly increase the inspection c...

AI Technical Summary

Problems solved by technology

[0003] 1) high cost

The cost of each flight sortie is about tens of thousands of dollars, and at least a few or even a dozen sorties are required for one inspection, which will inevitably greatly increase the inspection cost and development cost of aerial cameras

[0004] 2) long cycle

Since the number of flight sorties is greatly affected by the route and climate environment, the time of each flight sortie cannot be determined in advance, and must be determined at any time according to the current route and climate environment, which will greatly prolong the detection cycle of aerial cameras and reduce work efficiency
