This article analyzes how the image motion of infrared imaging equipment is generated in detail, and the infrared imaging equipment is fixed on an unstable platform. The method and algorithm of using micromachined accelerometer to get the image motion vector is proposed, and a measurement system of image motion vector which can be fixed on the infrared imaging equipment is developed. The experiments of image motion measurement and image stabilization are conducted, the results of which are compared to image stabilization through software. The effectiveness of theory and equipment are verified.
