Abstract
A method of processing a panoramic map based on an equirectangular projection is provided. The method comprises the following steps. A first and a second equirectangular projected panoramic images are captured through at least one lens at different time, respectively. The first and the second equirectangular projected panoramic images are perspectively transformed based on at least one horizontal angle, respectively. A plurality of first and second feature points are extracted from the first and the second equirectangular projected panoramic images, respectively. A plurality of identical feature points in the first and the second feature points are tracked. A camera pose is obtained based on the identical feature points. A plurality of 3D sparse point maps, in binary format, are established based on the at least one horizontal angle. The camera pose and the 3D sparse point maps are exported to an external system through an export channel.
