Rocket engine spraying pipe motion vision measuring method and portable infrared light emitting device used in same

The invention discloses a rocket engine spraying pipe motion vision measuring method and a portable infrared light emitting device used in same and relates to the rocket engine spraying pipe motion vision measuring field. The rocket engine spraying pipe motion vision measuring method and the portable infrared light emitting device used in the same solve the problem that a cooperative target cannot be correctly identified from a camera image plane due to the huge difference between a cold and hot trial running process and a simulated spraying pipe operating condition of the rocket engine when motion parameters of the rocket engine spraying pipe are measured. According to the rocket engine spraying pipe motion vision measuring method, a plurality of infrared luminous points are arranged on the outer surface of the rocket engine spraying pipe, an infrared optical filter is arranged before a lens of an image collecting device which collects images of the plurality of infrared luminous points which are arranged on the outer surface of the rocket engine spraying pipe, collected images are sent to a vision measuring system controlled computer, the rocket engine spraying pipe motion vision measuring purpose is achieved, and the infrared luminous points are achieved through a high luminance infrared light emitting device. The rocket engine spraying pipe motion vision measuring method is applicable to rocket engine spraying pipe motion vision measuring.
