Title:
Building height calculation method, equipment and storage media
Document Type and Number:
Japanese Patent JP6336117
Kind Code:
B2
Abstract:
Embodiments of the present invention disclose a building height calculation method, device, and storage medium. The method includes: acquiring an original picture including an image of a building; projecting the original picture to a surface of a preset sphere to form a projected picture; performing an edge detection on the image of the building in the projected picture to acquire a pixel height of the building; determining a projection angle of the projection on the preset sphere based on the pixel height of the building; and determining a height of the building based on the projection angle and a distance between the building and a capturing position of the original picture. In the embodiments of the present invention, a projection angle of a building is determined based on an original picture including an image of the building, and the height of the building is determined based on the projection angle and a distance between the building and a capturing position of the original picture. Hence, the height of the building can be obtained automatically and quickly based on the picture without manual involvements, thus reducing the cost of acquisition while improving the acquisition efficiency.
