The invention discloses an image processing method. The method includes determining a disturbance variable of a second image collection module on an image collected by a first image collection modulein advance in a condition that the first image collection module does not emit light and the second image collection module adjacent to the first image collection module emits light through acquiringimage data of a current to-be-detected object collected by the first image collection module; according to the disturbance variable, removing interference for data of each pixel point in the acquiredimage data and generating actual image data. According to the invention, influence on the image collection module on the other side by light sources of different modules in a condition that the imagecollection modules are placed in adjacent conditions is eliminated, so that mutual interference is eliminated, and real images of cash and bills are restored reliably through the acquired images. Therefore, cash and bill authentic identification capability is ensured. Besides, the invention also provides an image processing device and an image processing system having the above technical advantages.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and system. Background technique [0002] At present, automatic deposit and withdrawal machines for cash receipts are widely used, and cash receipt sorting machines for counting and sorting cash receipts are also widely used. These machines generally use CIS image sensors to obtain image information of cash receipts. In order to improve the accuracy of image recognition and the speed of image recognition, these machines generally use two or more CIS image sensors to acquire the image information of the front and back sides of the cash bill at one time. However, with the development trend of equipment miniaturization, high speed and low cost, it is an inevitable trend to reduce the length of the transmission channel of cash notes in the equipment. Among the existing equipment, the image sensors that collect the image information...
