Coordinate matching method of airborne laser radar and hyperspectral imager all-in-one machine

The invention relates to the technical field of remote sensing surveying and mapping, and particularly provides a coordinate matching method of an airborne laser radar and hyperspectral imager all-in-one machine. The method comprises the following steps of: S1, letting an imaging center of a laser radar and an imaging center of a hyperspectral imager pass through a same original point in space; acquiring first angle data and first distance data from the imaging center of the laser radar to a ground object point corresponding to point cloud and second angle data and spectral data from the imaging center of the hyperspectral imager to a ground object point corresponding to a pixel at the original point; S2, acquiring third angle data from the imaging center of the laser radar to a ground object point corresponding to the point cloud and fourth angle data from the imaging center of the hyperspectral imager to a ground object point corresponding to the pixel; S3, determining second distance data of the hyperspect
