[0040]Application overview
[0041]Simultaneous Localization and Mapping (SLAM) is widely used in the construction of high-precision maps. At present, when using SLAM to build high-precision maps, pinhole imaging models are often used to represent the imaging process of the camera. The imaging principle of the pinhole imaging model limits the angle of view of the camera. In practice, in order to obtain a better de-distortion effect, the angle of view of the pinhole camera is generally less than 90°. Therefore, when constructing a high-precision map, multiple movem...
