Abstract

The invention belongs to the field of artificial intelligence, and relates to a panoramic picture generation method and device based on a single PTZ camera, and the method comprises the steps: enabling the PTZ camera to shoot a plurality of pictures, so as to obtain a first picture set which is arranged according to a shooting sequence; deleting pictures of which the texture sparsity does not meet a first preset condition in the first picture set to obtain a second picture set; extracting adjacent pictures in the second picture set as picture pairs, performing region matching and feature matching on each picture pair, and judging whether feature points of effective feature matching of each picture pair determined according to a joint matching result of region matching and feature matching meet a second preset condition; and if so, sequentially splicing and fusing the pictures contained in the picture pair as to-be-spliced pictures according to a shooting sequence to obtain a panoramic picture. The invention further relates to a block chain technology, and the to-be-spliced picture can be stored in a block chain. The panoramic picture can be spliced by adopting the single PTZ camera, the hardware cost can be reduced, the application range is wide, and the splicing speed is high.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a method, device, computer equipment and storage medium for generating panoramic pictures based on a single PTZ camera. Background technique [0002] Panoramic stitching refers to a fixed observation point that can provide panoramic pictures with an azimuth angle of 180 degrees in the horizontal direction. There are two types of panoramic cameras currently on the market: fisheye panoramic cameras and multi-lens panoramic cameras. The fisheye panoramic camera is a fisheye panoramic camera that is equipped with a special ultra-wide-angle fisheye lens with a single sensor and relies on image correction technology to restore the image. The panoramic image finally generated by the fisheye panoramic camera still has a certain degree of distortion and distortion even after correction. Unnatural; and although the multi-lens panoramic camera can avoid the sh...
