摘要： Image processing method and device are disclosed. The method comprises a step of projecting a first image and a second image onto a first hemispherical projection model and a second hemispherical projection model, respectively; a step of determining a set of waiting-for-stitching surface region pairs on the first hemispherical projection model and the second hemispherical projection model; a step of generating a customized projection model based on the set of waiting-for-stitching surface region pairs; and a step of projecting the first image and the second image onto the customized projection model so as to create a third image. The first image and the second image are fisheye images captured in opposite imaging directions from the same position.

摘要： A method and an apparatus for constructing a three-dimensional channel, and a non-transitory computer-readable recording medium are provided. In the method, a depth image corresponding to a first panoramic image is generated. Then, channel object detection is performed on the first panoramic image to obtain channel object boxes in the first panoramic image. Each of the channel object boxes is four annularly interconnected arc-shaped sides, and each of the arc-shaped sides is a circular arc of a great circle. Then, a three-dimensional point cloud of a channel object in the first panoramic image is generated based on the first panoramic image, the channel object boxes and the depth image.

摘要： A method and an apparatus for determining a connection relation of subspaces, and a non-transitory computer-readable recording medium are provided. In the method, a plurality of sets of panoramic images respectively corresponding to two respective adjacent subspaces are obtained. Each set of the panoramic images includes two first panoramic images, and a second panoramic image photographed at a connection opening. Orientations of the connection openings are determined based on positions of the connection openings, and orientations of a camera. Relative positions of the two adjacent subspaces are determined based on correspondence relations between the two first panoramic images and parts of the respective second panoramic images. The connection relation of the subspaces is determined based on the connection relation determined based on the same subspace, the orientations of the connection openings, and the relative positions of the two adjacent subspaces.
