Abstract

The invention relates to a dynamic scene simulating device, especially relates to a mobile visible-light / infrared dual-wave-band dynamic scene simulating device, and belongs to the technical field of dynamic scene simulation. The device comprises a computer image generation system, a visible light dynamic scene generator, an infrared dynamic scene generator, a visible-light / infrared composite system, a projection optical system, a three-shaft displacement bench, an electric control subsystem, an environment control subsystem and a mobile elevating vehicle. The device provided by the invention is mobile, has radiation characteristics of two wave bands and is capable of providing clear and lifelike objects and background images for a tested composite imaging device. The mobile visible-light / infrared dual-wave-band dynamic scene simulating device is portable in size and is placed on the mobile elevating vehicle, convenient transportation among different experiment positions is realized, and testing work can be finished in different testing environments. The simulating device appears as an integrated unit on the mobile elevating vehicle, and after the transferring process is finished, the simulating device does not need to be calibrated again, so that the usage is very convenient.

Description

technical field [0001] The invention relates to a dynamic scene simulation device, in particular to a mobile visible light / infrared dual-band dynamic scene simulation device, which belongs to the technical field of dynamic scene simulation. Background technique [0002] The hardware-in-the-loop simulation technology of imaging system is the key technology of imaging system development, which can be used to evaluate the working characteristics of imaging system, so as to shorten the product development cycle and save product development funds. [0003] In recent years, the development of visible light / infrared composite imaging technology has been widely favored. As we all know, visible light images are rich in high-frequency components, which can better reflect the detailed information of the scene, but because they come from the reflection of ambient light, when the illumination is low, the imaging contrast will be seriously reduced; while infrared images come from the scen...
