The invention discloses an image debouncing method and device, which are used for solving the problems of high cost and high complexity of rolling shutter effect correction in image debouncing processing. According to the embodiment of the invention, curve fitting is carried out on discrete points formed by feature points of a current frame image and corresponding offsets; the rule formed by the obtained fitting result is suitable for the whole picture, namely, a correction matrix for calibrating any dimension in the imaging direction in the image can be determined according to the fitting result; and finally, pixel calibration is performed on the dimension by using a correction homography matrix obtained by the global homography matrix and the correction matrix of the dimension, and correction matrixes of other dimensions are determinedaccording to a proportional relation between distances between other dimensions and the dimension of the determined correction matrix after the correction matrix of a part of dimensions is determined. Calculation parameters are few, the calculation process is simplified, calibration fineness is high, the method is not limited by scenes, and finallyobtained video images are high in stability.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for deshaking an image. Background technique [0002] Image de-shaking technology refers to the removal of undesired unintentional motion from the actual motion of the camera, so that the processed video will become visually smooth, reducing the sense of jumping between pictures caused by unintentional motion. [0003] Existing debounce methods are mainly divided into two categories: optical debounce and electronic debounce. Optical anti-shake is to sense camera shake through the built-in instrument of the lens, and then achieve the de-shake effect by adjusting the position of the lens in the lens. Electronic debounce is to process the image by electronic means to reduce the influence of shake on the image. There are many methods of electronic anti-shake. One way is to sense the current camera shake through sensors such as a gyroscope, so as...
