Embodiment 1
[0030] see figure 1 , the panoramic image stitching method provided by Embodiment 1 of the present invention includes the following steps:
[0031] S101. Acquire a plurality of images for splicing panoramic images.
[0032] S102. Expand the multiple images into latitude and longitude images respectively.
[0033] In Embodiment 1 of the present invention, S102 may specifically include the following steps:
[0034] Obtain a model that expands the captured image to a latitude-longitude image;
[0035] According to the model, the multiple images are respectively expanded to obtain multiple longitude and latitude images respectively corresponding to the multiple images.
[0036] S103. Extract the spliced areas between the multiple latitude and longitude images respectively, obtain multiple spliced areas, and project the multiple spliced areas onto the unit sphere.
[0037] In Embodiment 1 of the present invention, S103 may specifically include the following steps:
