Image stabilization method, device, device and storage medium for infrared products

Abstract

The present application discloses a method, device, equipment and storage medium for anti-shake and image stabilization of an infrared product. The method includes: using a three-axis gyroscope to measure a three-axis angular velocity, and updating a rotation matrix according to the measured angular velocity; The updated rotation matrix is ​​corrected according to the set interval time in turn with the data measured by the three-axis geomagnetometer; the corrected rotation matrix is ​​calculated as the attitude angle, and the attitude angle is multiplied by the focal length of the compensation lens group to obtain the displacement; According to the displacement, the optical anti-shake module is used to adjust the position of the compensating lens group in the opposite direction, so that the compensating lens group is located at the target position, so as to perform optical compensation for the optical path where the shaking occurs. This application supports multi-axis anti-shake, detects motion with the help of three-axis gyroscope, three-axis accelerometer and three-axis geomagnetometer, and performs shift compensation for the detected "up and down displacement" and "forward, backward, left and right tilt" to avoid the vibration of the optical path. , the anti-shake performance is stronger, and the picture is more stable.

Description

technical field [0001] The present invention relates to the technical field of anti-shake, in particular to a method, device, equipment and storage medium for anti-shake and image stabilization of infrared products. Background technique [0002] When the infrared night vision device shakes or the target in the scene suddenly changes from a static state to a moving state, it is easy to cause the picture to be unstable, unclear, and noisy, and the later algorithm correction cannot achieve the desired effect. In order to avoid the blurring of the picture caused by factors such as jitter and improve the clarity of the image, the anti-shake technology came into being. [0003] At present, the existing anti-shake technology is divided into electronic anti-shake and gyroscope-based optical anti-shake. Among them, electronic image stabilization mainly relies on software algorithms to compensate for screen shake. By analyzing and collecting the image on the sensor, the edge image is...

Problems solved by technology

Because the electronic image stabilization uses software algorithms to compensate the shaky scene, and compensates the jitter by reducing the image quality, the anti-shake effect is not as good as the gyroscope-based optical image stabilization; while the general optical image stabilization only supports horizontal and vertical shake compensation, that is, it has two Axis anti-shake effect, does not support multi-axis (that is, more than two axes) anti-shake, resulting in unsatisfactory anti-shake effect
