Embodiment 1

[0026] figure 1 It is a schematic diagram of the imaging of the front lens of the present invention, figure 2 It is a schematic diagram of the imaging of the rear lens of the present invention. It can be seen from the accompanying drawings that the panoramic lens assembly includes a first fisheye lens 1 and a second fisheye lens 4. The first fisheye lens 1 is fixed in front of the front lens 2. And located on the same horizontal line, expand the field of view angle of the front lens 2 of the mobile device, image on the front image sensor 3 of the mobile device, and obtain the first fisheye image. The second fisheye lens 4 is fixed on the rear of the rear lens 5 of the mobile device, and is located on the same horizontal line, expands the field of view angle of the rear lens 5 of the mobile device, and forms an image on the rear image sensor 6 of the mobile device to obtain the second fisheye lens 4. Two fisheye images, the application program with panorama generation functio...

Embodiment 2

[0031] The optical axes of the first fisheye lens 1 and the front lens 2 of the mobile device coincide as much as possible, and the optical axes of the second fisheye lens 4 and the rear lens 5 of the mobile device coincide as much as possible.

Embodiment 3

[0033] The structure of the lens holder 7 is further designed, combined with image 3 and Figure 4 , the lens bracket 7 is provided with one or more pressing parts 8, the pressing parts 8 are elastic parts, the pressing parts 8 and the lens bracket 7 are integrally formed, and the connection between the pressing parts 8 and the lens bracket 7 is a section of vertical Straight segment, the free end of the vertical segment is a V-shaped or C-shaped curved segment, under normal conditions, the vertical segment of the pressing member 8 is parallel to the side wall of the lens bracket 7, when the mobile device 9 is inserted into the lens bracket 7 , the mobile device pushes the curved section to move, and the curved section presses the mobile device 9 against the side wall of the lens holder 7 under the action of its own internal force, so that the mobile device 9 and the lens holder 7 are closely matched.

[0034] When there is only one pressing member 8, the width of the pressi...

Abstract

The invention discloses a panoramic lens assembly and a panoramic generation method. The panoramic lens assembly comprises a first fisheye lens and a second fisheye lens, the first fisheye lens is overlapped with a front lens of the mobile device, the second fisheye lens is overlapped with a rear lens of the mobile device, the view field angles of the front lens and the rear lens of the mobile device are respectively expanded, imaging is carried out on a front image sensor and a rear image sensor of the mobile device, and first fisheye images and second fisheye images are obtained. The panorama generation method comprises the steps of 1, obtaining a first fisheye image and a second fisheye image; 2, obtaining first/second latitude and longitude images; 3, obtaining two groups of overlappedregions; 4, calculating and fusing the displacement values of the overlapped regions; and 5, combining the fusion area and the non-fusion area to generate a panoramic picture. According to the invention, a group of extended large-field-angle lenses is combined to form a group of panoramic lens assemblies, and the mode is low in cost and strong in applicability.

Description

technical field [0001] The invention relates to a panoramic lens assembly and a panoramic generating method, and belongs to the technical field of panoramic cameras. Background technique [0002] Panoramic pictures and videos have received more and more attention and applications because they can record 360-degree information and can be viewed with VR equipment to obtain an immersive experience. At present, panoramic pictures and videos are mainly taken by panoramic cameras. There are two types of panoramic cameras: stand-alone and plug-in. The price of stand-alone panoramic cameras is relatively high, and the post-processing generally needs to be realized on the computer side, which is suitable for more professional applications. ; Since the plug-in camera only includes a sensor and a lens module, and does not contain a processor, a battery, etc., the price is slightly lower, and it is suitable for general consumer needs. However, for consumers who want to try panoramic sh...
