Design of a novel testing system for measuring dynamic drift of gyroscope

Based on analysis of the traditional measuring method for dynamic drift of gyroscope, the principle and structure design of a novel testing system for dynamic drift of gyroscope in the conditions of high and low temperature is introduced. The system is controlled by computer software. The core parts of the system are CCD camera, image collection and processing. The software of image processing is written using VC. By adopting a fast algorithm not only the movement track of target is captured and plotted, but also the dynamic drift of gyroscope can be calculated automatically. The experimental results show that test system is very simple and practical and its resolution of the small angle measurement is better than 18′.
