[0020] figure 2 This is a schematic flowchart of the image stitching processing method in the first embodiment of this application. Such as figure 2 As shown, the image stitching processing method in this embodiment includes:

[0021] Step S11: Obtain images corresponding to multiple scene points. The image corresponding to each scene point includes a reference image and an image to be spliced. The reference image and the image to be spliced ​​are collected by image acquisition devices with different viewing directions, and The reference image and the image to be spliced ​​have an overlapping area.

[0022] In the embodiments of the present application, the images corresponding to the same scene point are derived from images collected by image acquisition devices (including cameras, image sensors, etc.) with different viewing directions of the same scene at the same shooting point. The shooting point refers to the shooting location of the image, that is, the geographic location ...

[0035] Figure 4 This is a schematic flowchart of the image stitching processing method in the second embodiment of this application. Such as Figure 4 As shown, the image stitching processing method in this embodiment includes:

[0036] Step S21: Acquire images corresponding to a plurality of scene points, the image corresponding to each scene point includes a reference image and an image to be spliced, the reference image and the image to be spliced ​​are collected by image acquisition devices with different viewing directions, and The reference image and the image to be spliced ​​have an overlapping area. This step is the same as the corresponding step in the first embodiment, and will not be repeated here.

[0037] Step S22: Extract the matching interest points between the reference image corresponding to each scene point and the image to be spliced.

[0038] In this embodiment, step S22 may further include:

[0057] Figure 5 This is a schematic structural diagram of an image stitching processing device in the third embodiment of this application. Such as Figure 5 As shown, the image stitching processing device 30 in this embodiment can implement the image stitching processing method in the first embodiment of the present application. The image stitching processing device 30 may specifically include: an image acquisition module 31, a matching interest point extraction module 32, and a matrix The calculation module 33 and the image stitching module 34.

[0058] The image acquisition module 31 is used to acquire images corresponding to multiple scene points. The image corresponding to each scene point includes a reference image and an image to be spliced. The reference image and the image to be spliced ​​are captured by image acquisition devices with different viewing directions. Collecting, and the reference image and the image to be stitched have an overlapping area. The matching in...

Abstract

The invention provides an image stitching processing method and device. The method comprises the following steps of: acquiring images which correspond to multiple scene points, wherein an image which corresponds to each scene point comprises a reference image and to-be-stitched images, the reference image and the to-be-stitched images are acquired by different image acquisition devices in the view direction, and the reference image and the to-be-stitched images have overlap areas; respectively extracting matching interest points between the reference image and the to-be-stitched images which correspond to each scene point; estimating rotation matrixes and offset matrixes among the different image acquisition devices in the view direction by utilizing the matching interest points which correspond to the scene points; and respectively stitching the images which correspond to all the scene points according to the rotation matrixes and the offset matrixes. According to the image stitching processing method and device provided by the invention, external references of the image acquisition devices are estimated by utilizing the matching interest points of the images which correspond to the scene points to stitch the images which correspond to all the scene points, and therefore, errors brought by the image acquisition devices can be more equally dispersed, and the stitching quality of the images is improved.

Description

Technical field [0001] This application relates to the field of image processing technology, and in particular to an image mosaic processing method and device. Background technique [0002] With the progress and development of the Internet, electronic maps have become an Internet application that is closely related to people's lives. People's daily life and travel are gradually inseparable from electronic maps. However, the traditional two-dimensional electronic map, due to abstract symbolic representation and insufficient precision, can only display limited information such as roads and buildings. For many users, two-dimensional electronic maps are relatively obscure to use, and cannot meet people's needs for more accurate, detailed, and better-use maps. Panoramic maps have emerged. [0003] As a new electronic map service, panoramic map has gradually become a hot spot for Internet map manufacturers. At present, most panoramic maps need to splice the images collected by the imag...
