Description of the Invention: [Technical Field] The present invention relates to an imaging method, and more particularly to a multi-view imaging method and system. [Prior Art] With the rapid development of digital imaging technology, the combination of audio and video multimedia applications in TV broadcasting and the Internet is increasingly diverse. Among the many types of image display, the ring image is displayed as a processing technique that turns the picture from flat to solid. The installation program first acquires images of different perspectives of a specific scene, and then uses the auxiliary software to perform image comparison and reconstruction, and then stitches into a smooth stereoscopic image. The completed image object can be displayed through animation or interface operation to show the different perspectives of the scene, so that the viewer can feel close to reality. Multi-view images can be used as a material for stereoscopic 3D video content in addition to ring image display. To put it simply, stereoscopic 3D images are based on one-dimensional images, providing left and right eyes to view different transient or parental images, allowing viewers to produce stereoscopic vision. Stereoscopic 3D imagery is a new generation of video development key projects. Currently, the dedicated organization is already drafting standards. ° Ding's stereoscopic 3D video content specifications are broadcasted through various consumer systems such as TV, computer and mobile phones. Generally, the multi-view image capture can be performed in two ways, one of which is to set the camera device around the target to operate the image of the individual position of the 201109817 angle image; the other way is to carry the camera device by the photographer. Around the scene, stop shooting the target along different points of view. Referring to the first figure, the figure is a schematic view of a multi-view image capturing environment of a prior art. As shown in the figure, the trace p is an arc centered on the target scene ,, and each of the upper positions corresponds to a different angle of view of the target scene 10. When it is necessary to obtain the specific viewing images corresponding to the positions A1, A2, and A3, the imaging devices u, 12, and 13 can be divided at the positions A1, A2, and A3 toward the mesh.
