Device and method for automatically adjusting auxiliary lighting equipment

Abstract

The invention discloses a device and a method for automatically adjusting auxiliary lighting equipment. The information of the auxiliary lighting equipment such as theoretical irradiation orientation, light source brightness and light source divergence angle can be obtained according to the gain value and the lens focusing and focusing location value of an acquisition camera at a night mode, and thus the auxiliary lighting equipment is controlled for carrying out parameter adjustment, so that the device and the method are optimal in image imaging effect in a night environment. The adjustment for the imaging effect can be automatically achieved in real time by utilizing the acquisition for site environment and location information, so that the adjustment effect accords with the site environment according to mature parameter adjustment experience values, and the adjustment method is more flexible and humanized.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a device and method for automatically adjusting auxiliary lighting equipment. Background technique [0002] With the rapid development of social economy and the enhancement of people's safety awareness, the demand for security monitoring systems is increasing, and its application fields are also expanding, and the performance requirements for equipment are also increasing. Moreover, no blind spot monitoring at night and high imaging effect under low light have gradually become the focus of competition. [0003] At present, there are two main methods to improve the imaging effect at night: one is to adjust the parameters of the camera itself, such as white balance, day and night status, exposure, etc.; the other is to add auxiliary lighting equipment, such as lasers and infrared lights. In a low-light environment, a single adjustment of the camera parameters has a ...

Problems solved by technology

The above method only approximates the focus position of the lens and the fill light position of the auxiliary lighting as a linear function. However, when different manufacturers and models of lenses are used, the number and division methods of the linkage division are also different, which makes the method difficult to transplant. The final adjustment effect is not very satisfactory, the setting of the linkage area is also relatively cumbersome, the operation is not easy, and the programming idea is not very clear
