Portable apparatus for measuring an infrared light emitting method and a moving visual rocket nozzles used in the process

Portable apparatus for measuring an infrared light emitting method and a moving visual rocket nozzles used in the method involving measuring the visual field of rocket engine nozzle movement. Solve the problems of the rocket engine nozzle motion parameters measured, since there is a huge difference between hot and cold nozzle testing process and simulate the working conditions rocket engine nozzle, resulting in the camera image plane can not correctly identify cooperative target. A plurality of infrared light emitting surface is disposed on the outer points rocket nozzles, an infrared filter, a lens image acquisition device prior to the image capture device the plurality of infrared light emitting points on the outer surface of the rocket engine nozzle motion image acquisition, and transmits the acquired images to the control computer vision measurement system, to achieve the purpose of the rocket engine nozzle moving visual measurement of the infrared light emitting point of infrared light emitting device with high brightness achieved. The present invention is applicable to the measurement of visual motion rocket engine nozzle.
