System and method used for camera fog-penetrating imaging function testing

Abstract

The invention discloses a system and a method used for camera fog-penetrating imaging function testing. The method comprises the steps of: placing a tested camera in a testing scene module, and enabling the tested camera to candidly photograph an evaluation analysis module to obtain a first imaging effect picture; adding fog in the testing scene module, determining fog concentration stability by afeedback adjustment module, and then enabling the tested camera is taken to candidly photograph the evaluation analysis module to obtain a second imaging effect picture; starting a fog-penetrating imaging function of the tested camera, and candidly photographing the evaluation analysis module to obtain a third imaging effect picture; and respectively comparing the third imaging effect picture with the first imaging effect picture and the second imaging effect picture, and determining whether the fog-penetrating imaging function of the tested camera is qualified. According to the method, the fog-penetrating imaging function of the camera can be effectively tested, closed-loop feedback adjustment is realized through arranging the feedback adjustment module, stability of humidity in the testing scene module is ensured, and accuracy of testing is further improved.

Description

technical field [0001] The invention relates to a system for testing the fog penetration imaging function of a camera, and at the same time relates to a corresponding function testing method. Background technique [0002] At present, dense fog has an increasing impact on road traffic safety and urban security monitoring. In the scene surrounded by dense fog, how to make the camera-based security monitoring equipment clearly display the monitoring picture has become a problem that many video equipment manufacturers need to solve. [0003] In order to solve this problem, many video equipment manufacturers have carried out targeted research in terms of hardware and software, and have achieved certain progress and results. However, the fog-penetrating imaging function of the camera is a relatively newly developed function, and currently there are few test methods for this function on the market. [0004] In the prior art, the closest method is to use artificial fog-making equi...

Problems solved by technology

[0005] However, the existing methods do not have clear requirements for the size, shape, and color of objects, nor do they have clear requirements for the clarity of clear objects, and cannot clearly evaluate the imaging effect of cameras in dense fog scenes; The fog imaging function has always been controversial, which has caused many cameras without fog penetration imaging function to be used as fakes, disrupting the order of the security market
