基于 MEMS 陀螺仪的实时电子稳像技术
Real-time Video Stabilization System Based on MEMS Gyroscope
摘要
采用MPU-6050 MEMS 陀螺仪和Xilinx FPGA 实现了一套实时电子稳像系统。该系统可对视频序列中的横向、纵向以及旋转方向的非意向运动(抖动)进行有效补偿,并保留操作者的意向运动。针对PAL 视频时,补偿范围为横向±240 像素,纵向±240 像素,旋转±45°,系统延时小于20 ms。给出了实现过程、硬件使用情况以及实验效果。
Abstract
A real-time video stabilization system is realized by using MEMS gyroscope (MPU-6050) and Xilinx FPGA. Unwanted camera motion (jitter) in horizontal, vertical, and rotation direction could be compensated, and wanted camera motion by the operator could be reserved. The compensation ranges are ±240 pixels in horizontal and vertical direction, and ±45°in rotation direction for PAL video. Time delay of the system is within 20ms. Implementation process, hardware consumption, and the experimental result are given.
