Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] A system for measuring the frame delay time of an optical measurement equipment camera system, including a camera system 2, a time system terminal 3, an image recording device 1, a control and display LED light array device 4 and an LED light array 5, and the time system terminal 3 is connected to the recording device 1. The camera system 2 and the control and display LED lamp array device 4 , the output end of the camera system 2 is connected to the image recording device 1 , and the camera system 2 images the LED lamp array 5 .
[0028] In the system for measuring the frame delay time, the turn-on and turn-off time of the LED light is much shorter than one frame time, which is relatively negligible;
[0029] In the system for measuring frame delay time, the recording device can superimpose the collected time information into the digita...
