Problems solved by technology

Users have to hold their mobile phones when taking panoramic photos, and it is difficult to take a complete picture of themselves
During the shooting process, the user cannot guarantee that the imaging focus of the pictures in all directions is on the same spherical surface, so the stitched panoramic photos have distortion and splicing distortion
The mobile phone needs to rely on software to compare two adjacent pictures in real time to estimate the angle between the two, and then guide the user to adjust the orientation of the mobile phone, so it takes a long time
Due to the different light intensity in each direction in the panorama, the exposure time and camera rotation must be adjusted synchronously in real time during the shooting process, which is cumbersome to operate
These methods take too long to capture a single panorama and therefore cannot achieve a high enough frame rate to compose a smooth video

Embodiment 1

[0119] Such as figure 1 and Figure 8 As shown, a device for taking virtual reality photos or virtual reality videos includes: a scanning drive device and a mobile phone, the scanning drive device includes a base 3, a horizontal rotating platform 2 and a vertical flipping platform 7, and the horizontal rotating platform 2 is set On the base 3, the vertical turning platform 7 is arranged on the horizontal rotating platform 2, and a carrier is arranged on the vertical turning platform 7, and two gaps are opened on the side of the carrier 1, and the two gaps are separated by a pupil distance, and the two The line connecting the center points of the gap is parallel to the rotation plane of the horizontal rotation platform;

[0120] The mobile phone is detachably placed in the carrier 1, the camera is set corresponding to the notch, and the width of the notch is greater than the width of the camera.

[0121] Such as Figure 5 As shown, the motor device of the horizontal rotating...

Embodiment 2

[0133] Such as Figure 9 As shown, when shooting, the two mobile phones are respectively fixed at the left eye position and the right eye position of the vehicle, and the device drives the two mobile phones to rotate and shoot in the vertical and horizontal directions, so as to obtain the panoramic picture information of the binocular perspective. Combining the shooting results of the two mobile phones to obtain a virtual reality picture.

Embodiment 3

[0135] Such as Figure 10 As shown, a mobile phone with binocular cameras is fixed on the vehicle. And make the left and right eye positions of the two cameras at the same level. The device drives the mobile phone to rotate and shoot vertically and horizontally, so as to obtain panoramic picture information from the binocular perspective. Combining the shooting results of the two cameras to obtain a virtual reality picture.

Abstract

The invention discloses a method and device for shooting a virtual reality picture or a virtual reality video and a scanning driving device. The problems that existing equipment needs multiple sets oflenses and is high in cost are solved. The shooting process is automated quick and forms image accurately. Videos are smooth, a photographer can photograph himself / herself, and the method comprises the steps that a mobile phone calculates a motor instruction and a photographing instruction according to user parameters and camera parameters, a scanning driving device is controlled to rotate the mobile phone in the horizontal direction and the vertical direction to scan the environment to generate panoramic pictures, and the two panoramic pictures at the left eye view angle and the right eye view angle are combined to generate a virtual reality picture; the virtual reality picture of the background environment is combined with the video of the moving target to generate a smooth virtual reality video; a scanning driving device for the operations comprises a base, a horizontal rotating platform, a vertical overturning platform and a carrier, the number of the mobile phones is one or two,the mobile phones are detachably placed in the carrier, and a camera of each mobile phone corresponds to the left eye or / and the right eye in position.

Description

technical field [0001] The invention relates to the technical field of virtual reality shooting, in particular to a method, device and scanning drive device for shooting virtual reality photos or virtual reality videos. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Virtual reality (vr) pictures are 3D panoramic pictures centered on the viewer's perspective (rather than 3D panoramic pictures centered on the observed object); virtual reality videos are composed of multiple consecutive virtual reality pictures as frames video. They have both three-dimensional and surround effects, which can bring an immersive experience to movie viewers. Virtual reality pictures and vide...
