Abstract

The invention belongs to the technical field of graphic processing, and discloses a building shadow analysis method and device, equipment and a storage medium. When the current moment is the preset sampling moment, the initial interpolation coordinate of the preset interpolation point in the preset coordinate system is obtained, the corresponding transformation matrix is determined according to the current illumination information, coordinate transformation is performed on the initial interpolation coordinate according to the transformation matrix, and the target interpolation coordinate is obtained. Determining the interpolation depth of the preset interpolation point according to the target interpolation coordinate, determining the mapping depth of the to-be-analyzed building under the shadow mapping according to the shadow mapping corresponding to the to-be-analyzed building, and determining the shadow rate of the to-be-analyzed building according to the interpolation depth and the mapping depth. Compared with the prior art that the shadow rate needs to be analyzed through manual statistics of the sun irradiation times, the shadow rate of the to-be-analyzed building is determined according to the interpolation depth of the interpolation point and the depth of the to-be-analyzed building on the shadow map, and the shadow rate analysis speed and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a building shadow analysis method, device, equipment and storage medium. Background technique [0002] With the development of science and technology and the progress of society, the speed of urbanization is getting faster and faster. With the accelerated development of urbanization, the buildings in the city are getting taller and taller, so the shadow ratio analysis of buildings is also more difficult. The current method of analyzing the shadow rate of a building by manually counting the number of sunshine of the building is inefficient, and the analysis accuracy of the shadow rate is poor, which is extremely time-consuming. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose o...
