Problems solved by technology

[0003] There are some problems in the existing turnaround shooting or panorama shooting through translation: on the one hand, turnaround shooting technology can only make the captured image extend in one dimension, and finally form a slender picture; especially when using a wide-angle or even fisheye lens When taking a turnaround, the captured picture only changes the perspective of one dimension, and cannot obtain enough pixel information for good distortion correction, so the panoramic picture converted from the captured image has a poor visual experience
[0004] Further analysis shows that the factors that cause the poor visual experience of turnaround shooting and panoramic shooting include: 1. The camera only changes in one dimension, and it is impossible to obtain more image information for cropping and stitching; 2. Fisheye distortion is isotropic, so, In the process of distortion correction of fisheye distortion, it is meaningless to obtain more image information only by translation

Embodiment 1

[0043] Such as figure 1 A shooting turntable for panorama shooting, virtual reality and stereoscopic image stitching is shown, including a power supply module, a control module, a power module and a mobile module, and the mobile module includes a main rotation module and a camera movement fixed on the main rotation module module, a camera is fixed on the camera moving module;

[0044] The power supply module is divided into two parts: the power module power supply module and the control module power supply module. Specifically, the mains power is respectively transformed to the operating voltage of the control module and the power module, and power is independently provided to these two modules to ensure their Can work stably;

[0045] The control module is used to control the power module;

[0046] The power module is used to drive the main rotation module to rotate and the camera to move on the camera moving module.

[0047] The difference in this patent is that, in addit...

Embodiment 2

[0064] Such as Figures 4 to 6 As shown, the difference between this embodiment and Embodiment 1 is that the camera movement module includes a translation module 3, the translation module 3 is vertically fixed on the main rotation module 4, and a camera 2 is installed on one side of the translation module 3, and the power module It includes two motors 0, which are respectively used to drive the main rotation module 4 to rotate and the camera 2 to move between the two ends of the translation module 3.

[0065] The camera 2 moves in two different dimensions through the main rotation module 4 and the translation module 3 during the shooting process to ensure that the content of the shooting is changed in two dimensions.

[0066] For this embodiment, in order to obtain better image information required for distortion correction, the moving range of the camera 2 on the translation module 3 should be as large as possible, which is very meaningful for large-scale shooting of large sc...

Embodiment 3

[0068] Such as figure 2 , 3 , 7 and 8, the difference between this embodiment and embodiment 1 is that the camera moving module includes a connecting rod 5 and a rotating module 1, and the connecting rod 5 is fixed on the main rotating module 4 at a certain angle, and A rotation module 1 is installed on one side, and a camera 2 is fixed on the rotation module 1. Two motors 0 are mechanically connected to the main rotation module 4 and the rotation module 1 respectively, so as to drive the rotation of the main rotation module 4 and the movement of the camera 2 on the rotation module 1. track.

[0069] The camera 2 changes in two dimensions simultaneously through the main rotation module 4 and the rotation module 1 during the shooting process, and can set different motion trajectories according to shooting requirements, so as to capture more image information for distortion Correction and image cropping and splicing can finally obtain an image with better visual experience, a...

Abstract

The invention relates to a shooting rotary camera oriented on panoramic shooting, virtual reality and three-dimensional image stitching. The shooting rotary camera comprises a power supply module, a control module, a power module and a moving module; the moving module comprises a main rotary module and a camera moving module fixed on the main rotary module; a camera is fixed on the camera moving module; the power supply module is used for respectively supplying power to the power module and the control module; the control module is used for controlling the power module; and the power module is used for driving the main rotary module to rotate and the camera to move on the camera moving module. The one-dimensional motion of the camera on the main rotary module is superposed on possible multiple motions different from the dimensionality of the main rotary module on the camera moving module, so that the two-dimensional or more spatial moving trace can be combined; enough pixel information used for distortion correction is also ensured while the fact that more image information can be obtained to perform cutting and stitching can be ensured; and thus, the quality of a processed picture is greatly increased.

Description

technical field [0001] This patent relates to the field of shooting equipment, in particular to a novel shooting turning machine. Background technique [0002] With the popularity of cameras and the strengthening of mobile phone shooting functions, people have higher and higher requirements for shooting, and one of them takes pictures from different angles by rotating the camera lens, and then cuts and stitches these pictures to form a large picture. The shooting technology of pictures is called turn-around shooting or shaking head shooting. This shooting technology has been widely used in various large-scale scene shooting, such as group photos and landscapes. If a fisheye camera is used instead of an ordinary camera to shoot to obtain a wider viewing angle, and multiple pictures are taken by rotation or translation and then cropped and stitched, it is called panoramic shooting. Panoramic shooting and turnaround shooting technologies have been widely used in many fields, e...
