System for testing anti-fog function of video device

Abstract

The invention discloses a system for testing an anti-fog function of a video device. The system comprises an airtight haze environment test box, a haze generation chamber and a haze waste gas treatment chamber are arranged on the outside of the haze environment test box, a tripod head is arranged on the outside of the haze environment test box, the video device is installed on the tripod head, a turbine air circulation fan, an anti-deposition fan, a movable guide rail and a movable objective table are arranged on the bottom surface of the inside of the haze environment test box, a lamp box is arranged on the side, right opposite to the video device, of the movable objective table, a test graphic card is installed on the lamp box, an illumination lamp is arranged at the top of the inside of the haze environment test box, and an air exchange device and a sealing push-pull door are arranged on the top surface of the outside of the haze environment test box. The system solves the problems that an existing anti-fog test device can only test in a fixed point and cannot test in a dark chamber environment and provides a flexible and effective test method for researches of anti-fog capacity of the video device.

Description

technical field [0001] The invention relates to the research field of fog penetration of video equipment, in particular to a fog penetration function test system for video equipment. Background technique [0002] The emergence of smog has caused serious harm to the society, not only directly affecting human health, but also indirectly affecting traffic safety, security monitoring systems, especially video monitoring systems. In order to solve this application dilemma, many video equipment manufacturers have carried out research and development of fog penetration functions from the aspects of physical technology, data structure and algorithm, and achieved certain results. But so far, most of the defogging capabilities of these fog-permeable video devices have been evaluated from a qualitative perspective. There are few reports on the quantitative evaluation of relevant indicators for the quality of the acquired images, and there is no mature detection and evaluation standard ...
