Embodiment Construction
[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0050] The technical solution of the present invention provides a method for testing the dynamic range of a camera with a closed LED light source light box, which specifically includes: setting a closed box structure; The airtight box is divided into two adjacent and independent first test space and second test space; by setting two adjacent airtight test spaces, two independent airtight light box systems are formed, providing Isolated closed test light source environment;
[0051] At the front of the first / second test space, a front panel with a camera test hole is arranged;
[0052] In the first / second test space, the first / second LED light sources are set respectively; by setting two groups of controlled LED light sources whose light domains are independent of each other, mutual crosstalk between the two groups of test light sources can be avoided, ...
