Portable recording equipment for law enforcement plays a key role in the law enforcement process of evidence, but because it is worn on the body, the recorded video shakes seriously, which affects the subsequent viewing and processing. In order to improve the anti-shake effect of portable recording equipment for law enforcement, a scheme combining two-axis mechanical anti-shake and video anti-shake was proposed. At the same time, a dynamic calibration scheme was proposed to improve the stability of anti-shaking effect of law enforcement instrument in complex environment. In order to solve the IMU data distortion problem caused by the restriction of collision to the two-axis mechanical anti-shake of the instrument, a fast recovery scheme was proposed.
