Device and method for automatically adjusting parameters of camera

Abstract

The invention discloses a device and a method for automatically adjusting parameters of a camera at different time intervals according to position information of a front end holder device, so that the parameter adjustment of the camera is more accordant with actual condition. The method comprises the steps of: arranging a GPS (Global Positioning System) module on the front end holder device to obtain local longitude and latitude and time information and transferring a parameter predetermined value of the camera in the area and at a specific time interval in a storage module to adjust the parameters of the camera. According to the device and the method for automatically adjusting parameters of the camera, the parameter adjustment time is set according to the actual geographic location and seasonal time information of the holder, so that the parameter adjustment of the camera is more accordant with actual condition; the phenomena of image frequent change, color distortion, instability and the like, caused by the situation that most cameras at present use a certain object in a scene as a reference to automatically adjust the parameters and if the scene is changed, a reference substance has to be searched again, are avoided with relatively mature parameter adjustment experience value and with time as the adjustment watershed; and the adjustment is more ideal, flexible, humanized and pertinent.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a device and method for realizing automatic adjustment of camera parameters by using a GPS module. Background technique [0002] At present, 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. In addition to traditional main application places such as government departments, finance and telecommunications industries , Railway stations, hotels, various leisure and entertainment venues, tourist attractions, squares, streets, companies and individual residences have also become the main application places for security monitoring systems. [0003] The security monitoring system has two key technical points, one is the control of monitoring products, and the other is the display of monitoring images. Therefore, the research...

Problems solved by technology

Although multiple parameters of the camera have been opened to the user and can be adjusted freely, but because the influence of each parameter on the imaging is not well understood, manual adjustment by the user often fails to achieve the desired effect

[0004] On the other hand, even if the image effect is changed by adjusting the camera parameters, the camera will keep looking for another reference point when the field of view changes, the scene changes, the reference scene moves, and the ambient light changes frequently Adjust the current parameters with the new benchmark, so that the image will appear blurred, jittery, color cast, unstable, etc., and the image effect will still not be ideal
