Abstract

The invention discloses a method for setting a dynamic exposure compensation digital camera. According to the method, the shutter speed and iso sensitivity value of a camera can be automatically adjusted according to the intensity of ambient light, and when the intensity of the ambient light is less than a certain value, the device can automatically turn on a supplement lamp to implement image acquisition of all-weather field environments at the scene; the acquired low-light image information can be automatically gained through an automatic gain control (AGC) unit; the exposure time can be automatically controlled through an automatic exposure control (AEC) unit in a low-light state, and images can be automatically shot in the low-light state; and the image acquisition of the all-weather environments can be implemented through a low-power supplement lamp, an existing data acquisition operation of water and rainfall information is basically powered by solar energy and has high requirements on the power consumption of products, the digital camera that adopts the technology only needs the low-power supplement lamp (3-8W), a traditional camera needs a supplement lamp with the power ofmore than 30W, and thus the scheme of the invention has an obvious advantage.

Description

technical field [0001] The invention relates to a monitoring digital camera of an outdoor natural disaster early warning system, in particular to a method for setting a dynamic exposure compensation digital camera. Background technique [0002] There are many natural disaster-prone areas in our country, and it is necessary to strengthen disaster monitoring to minimize the loss of personnel and property. In recent years, with the rapid development of the mobile Internet and the emergence of various intelligent terminals, disaster monitoring technology has been continuously improved, basically overcoming a large number of disadvantages caused by early manual survey and alarm. At present, in related technologies, rain gauges and water level gauges are used to monitor on-site water and rain conditions, and relatively accurate data can be obtained, but the understanding of the on-site environment is not intuitive. Later, with the development of electronic technology, camera techn...
