A method of electronic anti-shake based on gyroscope

Abstract

The invention provides a gyroscope-based electronic anti-shake method, the method comprising the following steps: the X, Y, and Z axes of the gyroscope coincide with the Sensor respectively; and the rotation angles of the X, Y, and Z axes of the Sensor are detected by the gyroscope ;Match the rotation angle with the current lens field of view; use the feature point matching method to do motion estimation between two frames, and calculate the projection matrix P-Matrix of the two frames; pass the gyroscope rotation angle and P-Matrix through the method The weights are fused together; use the fused projection matrix to project the current frame, and then cut out the image of the target size, so as to achieve the anti-shake effect. Using the anti-shake method of the present invention can effectively solve the background drag caused by the movement of large-area objects, and at the same time reduce the influence of image noise on the feature point matching method at night.

Description

technical field [0001] The invention belongs to the technical field of security monitoring, and in particular relates to a gyroscope-based electronic anti-shake method. Background technique [0002] As the security monitoring field has more and more complex requirements for camera application scenarios, the vibration of the installation environment will have more and more influence on the image. In order to ensure that the vibration in the environment can be filtered out in various complex environments, it is particularly important to collect clear and stable images. [0003] During the shaking process, the data collected by the Sensor will change with the swing of the lens, which will cause shaking and blur the image, making it impossible to achieve the purpose of monitoring. [0004] Simple electronic anti-shake cannot solve the problem of background dragging and low-light noise caused by large objects passing through the lens, so adding a gyroscope can directly determine...
