A system and method for testing the fog penetration imaging function of a camera

Abstract

The invention discloses a system and method for testing the imaging function of a camera through fog. Wherein, the method includes the following steps: placing the tested camera in the test scene module, making the tested camera capture the evaluation analysis module to obtain the first imaging effect picture; adding fog in the test scene module, and determining the fog concentration through the feedback adjustment module After stabilization, make the camera under test capture the evaluation analysis module to obtain the second imaging effect picture; open the fog penetration imaging function of the camera under test, capture the evaluation analysis module, and obtain the third imaging effect picture; compare the third imaging effect picture with the first The imaging effect picture is compared with the second imaging effect picture to determine whether the fog penetration imaging function of the camera under test is qualified. This method can effectively test the fog penetration imaging function of the camera. By setting the feedback adjustment module, the closed-loop feedback adjustment can be realized, the stability of the humidity in the test scene module can be ensured, and the accuracy of the test can be 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...

[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
