Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] refer to figure 1 , figure 2 . In the embodiments described below, the composite MEMS-IMU electronic image stabilization device consists of an optical lens 1, an image sensor 2, an image sensor readout circuit 3, a signal processor 4, a MEMS-IMU 5 and a camera structural frame 7. Among them, the optical lens 1, the image sensor 2 and the circuit assembly 6 are assembled into an integral firmware, which is installed on the inner frame of the camera 7 to ensure that the image sensor 2 and the MEMS-IMU5 can maintain a fixed coordinate connection relationship. During the working process, the image sensor 2 converts the incident light signal into an electrical signal, which is sent to the readout circuit 3 of the visible light image sensor, and the output circuit converts the electrical signal into the output original video image data; the original video image data...

Abstract

The invention discloses a compound MEMS-IMU electronic image stabilizing apparatus. The electronic image stabilizing apparatus has a simple structure, low cost, high image stabilizing precision, high anti-interference performance, and small operation amount of image processing motion estimation. The apparatus is integrated by an image sensor reading circuit (3), a signal processor (4), an MEMS-IMU (5) and a circuit component (6). An image sensor (2) converts an optical signal from an optical lens (1) into an electrical signal, and transmits the electrical signal to the reading circuit so as to output original video image data; and the signal processor inputs inertia measurement information of the MEMS-IMU in signal processing of image electronic image stabilization, so as to merge the original video image data with inertia measurement data output by the MEMS-IMU, the motion vector of a camera is solved through MEMS-IMU information, jitter component is separated through adaptive Kalman filter, and motion compensation is performed on the original video data so as to output stable video data.

Description

technical field [0001] The invention relates to an electronic image stabilization device which fuses MEMS-IMU and image information in the field of image processing. Background technique [0002] Image stabilization technology is widely used in robot remote control systems, sight and sight systems, video surveillance systems, and image navigation systems. It is a key preprocessing technology for target detection and tracking, and an indispensable and important video enhancement technology for mobile imaging systems. Obtaining stable and clear video output is of great significance to the development of its follow-up work. The working environment of the camera system is often uncontrollable, and it is inevitably affected by the vibration of the carrier, causing unstable jitter interference to the video image. Vibration interference will cause blurred images, which may lead to false alarms and missed alarms or more serious consequences during target recognition; effectively el...
