Embodiment 1

[0094] See figure 2 , the embodiment of the present invention provides a panoramic image stitching method, which can be applied to a panoramic image stitching device, such as a video camera, a multi-eye camera, etc., wherein the implementation process of the method can be described as follows.

[0095] S101: Acquire a source image video stream, and determine a preset location information set, wherein one piece of location information is used to indicate a specific coordinate position of a source image block in the source image video stream;

[0096] S102: Based on each location information in the location information set, intercept corresponding source image blocks from the source image video stream;

[0097] S103: Generate multiple target images based on the acquired source image blocks, and stitch the multiple target images to obtain a corresponding panoramic image.

[0098] In S101, the panoramic image stitching devices at different positions, such as multiple source imag...

Embodiment 2

[0154] See Image 6 , based on the same inventive concept, an embodiment of the present invention provides a panoramic image stitching device, including an acquisition module 61 , a matching module 62 and a stitching module 63 .

[0155] Wherein, the acquisition module 61 is used to obtain the source image video stream, and determine a preset position information set, wherein a position information is used to indicate a specific coordinate position of a source image block in the source image video stream;

[0156] A matching module 62, configured to intercept corresponding source image blocks from the source image video stream based on each position information in the position information set respectively;

[0157] The stitching module 63 is configured to generate a plurality of target images based on the acquired source image blocks, and stitch the plurality of target images to obtain a corresponding panoramic image.

[0158] In a possible implementation manner, the device f...

Embodiment 3

[0187] Based on the same inventive concept, an embodiment of the present invention provides a panoramic image stitching device, which includes:

[0188] at least one processor, and

[0189] a memory, a communication interface communicatively connected to the at least one processor;

[0190] Wherein, the memory stores instructions executable by the at least one processor, and the at least one processor uses the communication interface to execute the method described in Embodiment 1 by executing the instructions stored in the memory.

Abstract

The embodiment of the invention provides a panoramic image splicing method and device to solve the low efficiency of panoramic image splicing in the prior art. The method includes acquiring a source image video stream and determining a preset position information set, wherein one piece of position information is configured to indicate the specific coordinate position of a source image block in thesource image video stream; and cutting a corresponding source image block from the source image video stream based on each piece of position information in the position information set; generating aplurality of target images based on the obtained source image blocks, and splicing the plurality of target images to obtain a corresponding panoramic image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a panoramic image stitching method and device. Background technique [0002] At present, the methods of obtaining a panoramic image of a wide viewing angle scene containing various image information mainly include: 1. Using a single optical system to realize a hyperhemispheric imaging system, such as a fisheye lens system, can form a wide viewing angle scene exceeding 180° Panoramic image; 2. Adopt the method of "recklessly spelling", that is, the overlapped image sequences collected by multiple cameras are directly spliced ​​without any processing to form a panoramic image of a scene with a wide viewing angle; 3. Use the central processing unit (Central Processing Unit, CPU) and graphics processing unit (Graphics Processing Unit, GPU) perform coordinate transformation on overlapping image sequences collected by multiple cameras, project the source image onto a t...
