The invention belongs to the technical field of image processing, and particularly relates to a two-dimensional code decoding method and device, a piece of terminal equipment and a computer readable storage medium. According to the method, if the decoding of a current decoded frame fails, an interval frame extracting approach will be adopted. First, the number of two-dimensional code locators identified from the current decoded frame is determined. Then, the number of interval frames between two adjacent decoded frames is determined according to the number of two-dimensional code locators. Finally, an image frame spaced apart from the current decoded frame by the interval frames is determined as a new current decoded frame, and continues to be decoded. The number of interval frames is negatively correlated with the number of two-dimensional code locators. The fewer the two-dimensional code locators identified from the current decoded frame are, the smaller the probability that the adjacent image frame is successfully decoded is. A farther image frame can be determined as a new current decoded frame. Therefore, frame-by-frame decoding of image frames with smaller decoding success probability is avoided, and the time required for decoding is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a two-dimensional code decoding method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the introduction of the UnionPay QR code payment standard, the decoding function of the QR code has become an essential function of various payment terminals, but the processor frequency of some payment terminals is low and the processing capacity is limited. In the case of a high frame rate, it may not be possible to read valid images from the camera in time, resulting in a long decoding process. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a two-dimensional code decoding method, device, and terminal equipment to solve the problem that in the prior art, when the frame rate of the image collected by the camera is high, it may not be possible to read it from the cam...
