Background technique

Traditional remote sensing earth observation is mostly a single-angle vertical observation, which can only obtain the information of one angle direction of the ground object, and only obtain the information of the ground object in the two-dimensional space. However, the ground object exists in the three-dimensional space. The model of expressing the three-dimensional vegetation structure on the three-dimensional plane will inevitably lead to the lack of information on the structure of the ground object. Therefore, the amount of information obtained by the sensing measurement method is insufficient, which can easily lead to low precision and large uncertainty in the remote sensing inversion results. It is difficult to meet the needs of various remote sensing applications. As a frontier field of remote sensing technology, multi-angle earth observation is a hot spot in remote sensing research at home and abroad. As a relatively new observation method, multi-angle remote sensing adds angle information to remote sensing data. By observing ground targets in multiple directions, it enriches the three-dimensional structural feature information of the target, so it has the potential to invert the structural parameters of ground objects. , which provides the possibility to improve the inversion accuracy of parameters.
