| 英文摘要 | In the field of aerospace and planetary science, precise measurement of the motion state of a moving carrier represents an important part of scientific exploration missions. the paper presents a fusion of the stereo vision and IMU to measure the velocity, angle, and angular velocity of a moving carrier precisely. First, a stereo camera self-calibration model with additional geometric constraints is developed, which accuracy of better than 0.379 pixels is achieved. Then, a three-dimensional reconstruction with accuracy of better than 0.727 pixels is achieved. Finally, the spatial relationship between the carrier, the stereo camera, and the IMU is used to determine the absolute pose change of the moving carrier relative to the center of the Earth. The proposed method ensures high measurement accuracy of the velocity, angle, and angular velocity of the moving carrier of better than 0.19 mm/s, 0.09 degrees, and 0.127 degrees /s, respectively, which can provide reliable technical support for the motion state estimation of deep space moving vehicles. |
