Intelligent acquisition method and device for vehicular photographing equipment, and car digital video recorder

Abstract

The invention discloses an intelligent acquisition method and device for vehicular photographing equipment, and a car digital video recorder. The intelligent acquisition method comprises the following steps of: performing photographing according to a photographing frequency so as to generate video data, and sampling the video data according to a sampling frequency so as to obtain sample images; calculating the brightness average value of the sample images, wherein the brightness average value of the sample images is an average value of brightness values of continuous X-frame sample images, and X is a positive integer; and determining a pre-set photographing frequency corresponding to the brightness average value according to the brightness average value, and performing photographing according to the pre-set photographing frequency corresponding to the brightness average value so as to generate the video data. According to the intelligent acquisition method disclosed by the invention, the brightness values of the continuous X-frame sample images in the video data are acquired, so that the brightness average value is obtained and used for adjusting the photographing frequency in real time; therefore, the better video data is obtained; and recorded data with relatively high referential meanings is provided for users.

Description

technical field [0001] The present invention relates to the technical field of electric communication, and more specifically, relates to an intelligent collection method and device for vehicle-mounted camera equipment and a driving recorder. Background technique [0002] With the continuous development of mobile technology, the continuous increase of motor vehicles, and the continuous complexity of traffic conditions, the recording and processing of driving data by vehicle-mounted intelligent systems will become the main direction of future development in the transportation field, as one of the important parts of vehicle-mounted intelligent systems. Vehicle-mounted camera equipment has gradually become a hot spot of current research. The on-board camera equipment can help the driver to record the driving scene in real time, and can restore the driving state at each moment when necessary, as a driving reference. [0003] The vehicle-mounted camera equipment currently on the ...

Problems solved by technology

Obviously, when the light is relatively strong, such as backlighting, and the shooting frequency of the on-board camera equipment is low, the exposure will transition and become white, resulting in the loss of a large amount of driving data; when the light is weak and the shooting frequency of the on-board camera equipment is low When it is too large, it will make the picture quality rough, grainy and even make it difficult to see the subject clearly.

In either case, the data recorded by the on-board camera equipment will lose its reference value
