| Abstract: |
| Based on the monocular visual system and the spacecraft image with the marker, this work uses the Convolutional Neural Network(CNN) theory in deep learning to accurately measure the three-dimensional attitude angle of the spacecraft, the distance from the shooting point and the offset from the shooting center. We take the advantage of machine learning theory to realize the network autonomously learning characteristics of samples, which will greatly reduce the error of dynamic measurement. At the same time, this method also avoids the complicated process of manually extracting features, realizing arbitrary, accurate and rapid measurement, and plays a key role in the attitude estimation and distance measurement of the spacecraft during assembly and launch. |
