Problems solved by technology

[0003] Correspondingly, one of the elements that affect the clarity of the document image information captured by Gaopai is the exposure adjustment of Gaopai; on the one hand, the existing Gaopai has the function of automatic exposure adjustment, but the automatic exposure The scope of application of the adjustment function is small, and for black cards, the clarity of the captured image information is poor; The automatic exposure adjustment function of Gaopai, but the captured image will have reflections in the image information due to the influence of high exposure conditions, which will affect the retention of image information and subsequent recognition; correspondingly, Gaopai The exposure adjustment of the camera supports manual adjustment. Therefore, in view of the above two problems, operators often use manual adjustments to adjust the exposure of the camera, but this method is extremely poor in intelligence, cumbersome to operate, and Consuming labor costs; therefore, a high-precision automatic adjustment method for the high-speed camera that can adjust the exposure according to the color of the card is needed

Abstract

The invention discloses a high-precision exposure regulation and control method and system applied to a high-speed photographic apparatus, and a medium. The method comprises the following steps: setting a photographing mode, first color information and second color information; acquiring a first image based on the shooting mode, the first color information and the second color information; configuring an image processing algorithm and a card identification template; performing region confirmation operation on the first image based on an image processing algorithm and a card recognition template to obtain a first region; configuring a color processing algorithm and a statistical algorithm; acquiring first parameter information; based on a color processing algorithm, a statistical algorithm and the first parameter information, executing negative film color judgment operation on the first area to obtain an exposure judgment reference; executing exposure adaptive matching operation based on the exposure judgment reference and the camera shooting requirement; according to the invention, the high-speed photographic apparatus can be automatically controlled to be adjusted to a proper and accurate exposure degree according to the image information of the card under the condition that the external exposure condition does not need to be adjusted.

Description

technical field [0001] The invention relates to the technical field of image capture and processing, in particular to a high-precision exposure control method, system and medium applied to a high-speed camera. Background technique [0002] In the prior art, the high-speed camera is used on the terminal equipment to capture the information of important card certificates such as bank cards and ID cards. For different types of documents, the adaptive modulation of the shooting parameters of the high-speed camera is particularly critical. [0003] Correspondingly, one of the elements that affect the clarity of the document image information captured by Gaopai is the exposure adjustment of Gaopai; on the one hand, the existing Gaopai has the function of automatic exposure adjustment, but the automatic exposure The scope of application of the adjustment function is small, and for black cards, the clarity of the captured image information is poor; The automatic exposure adjustmen...
