Problems solved by technology

The stereoscopic video shot by this solution is collected in time-sharing, and it is impossible to collect 360 panoramic stereoscopic images at the same time. Therefore, it is generally suitable for shooting static scenes, but not suitable for restoring dynamic scenes in virtual reality applications.
Moreover, this panoramic stereo camera system is complex and cannot be taken portablely.
[0005] 2. Multi-cameras are used to simultaneously acquire the video data of the left and right eyes for post-processing. Therefore, an array composed of dozens of cameras has also appeared for stereoscopic shooting. Although the problem of simultaneous shooting has been solved, high-speed data transmission and acquisition equipment are required, and the price is high. , and the overall volume is also very large, which is not conducive to carrying
[0006] The main disadvantages of the prior art are: 1. The panoramic video shot by the fisheye camera is monocular imaging without stereoscopic effect; 2. The stereo camera shot by the binocular circular track cannot take panoramic shots in real time, and the system is complicated and cannot be taken portablely; 3. At present, the existing multi-camera stereo camera solutions in foreign countries are expensive and bulky, which is not conducive to portability

Embodiment 1

[0032] Such as figure 1 , figure 2 , Figure 7 As shown, the present invention provides a head-mounted panoramic 360-degree stereo camera device, comprising: a horizontal camera group 1, a head ring 2, a horizontal camera bracket 3, a fisheye camera 4 and a fisheye camera bracket 5; the horizontal camera bracket 3 In addition to fixing the horizontal camera group and the fisheye camera bracket, it is also used for fixing when the user wears it; the head ring 2 is used as a fixed auxiliary part, which can be adjusted in size to adapt to the shape and size of the user's head to achieve the best The fixation effect and comfort. The present invention adopts 8-16 camera groups composed of horizontal cameras 1 that are evenly arranged in the radial direction in the horizontal direction. The circumferential direction is evenly arranged in the horizontal camera support 3; and the fisheye camera support 5 is arranged on the top of the middle part of the head ring 2, and the fisheye...

Embodiment 2

[0034] On the basis of the above-described embodiments, the head-mounted 360-degree stereoscopic camera device of the present invention also includes a control module and a signal processing module, and the control module is used to control the synchronous shooting of each horizontal camera 1 and fisheye camera 4 to ensure that the image or Each frame of the video is collected at the same time, and all pixels correspond to the same scene; the control module is also used to complete other operations other than the functions of the signal processing module; the signal processing module is used to control the data compression of each horizontal camera 1 and fisheye camera 4, Storage and transmission; realizing stitching of panoramic images and presentation of stereoscopic images.

Embodiment 3

[0036] Such as image 3 , Figure 4 and Figure 5 , Figure 6 As shown, on the basis of the foregoing embodiments, the present invention also provides a head-mounted panoramic 360-degree stereo camera processing method, the specific steps are as follows:

[0037] Step 1: Obtain the image data of the horizontal camera group and the fisheye camera respectively;

[0038] Step 2: Calibrate the internal parameters of each camera in the horizontal camera group 1 and the fisheye camera 4, remove the lens distortion and compensate the directional deviation between each lens; drive the horizontal camera group 1 and the fisheye camera 4 by the synchronous signal, and collect After storing the image / video data, all the images of the horizontal camera group are stitched together; the images of the fisheye camera are stitched into it;

[0039] Step 3, after equirectangular projection is performed, a panoramic image is acquired.

[0040] The correction in the above step 2 refers to obtai...

Abstract

The invention provides a head-mounted panoramic stereoscopic 360-degree photographing device and photographing processing method. The device includes horizontal cameras, a headband, a horizontal camera bracket, a fisheye camera and a fisheye camera bracket. The device has the horizontal camera bracket and the fisheye camera bracket for fixing. The size of the headband can be adjusted to adapt to the head shape and size of a user. By adopting the above scheme, the invention has the advantages that 1, a head-mounted design is adopted, wearing is convenient, photographing at anytime and anywhereis facilitated, and a head-top camera is additionally installed, and realizes a panoramic photographing effect of 360 degrees + 180 degrees together with a horizontal ring-shaped radiation-type-installed camera group; 2, a distributed storage processing scheme avoids the bottleneck problem of video transmission in high definition; and 3, two-way image or video signals are generated through left-right eye simulation, a human eye parallax principle is utilized to generate a panoramic stereoscopic image or video effect after two eyes respectively obtain different two-way signal input, and a panoramic stereoscopic function is realized.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a head-mounted panoramic 360-degree stereo camera device and a camera processing method. Background technique [0002] Traditional single-eye panoramic 360-degree cameras generally use dual fish-eye cameras, and the images obtained by stitching together fish-eye photos are processed by software to obtain 360 real scenes, which retain the authenticity of the scene and have a certain impact on the popularization of virtual reality. Meaning, although the video it shoots can fully display the scenery within the 360-degree spherical range, it lacks three-dimensional effects, and it still seems powerless in occasions that require a high sense of immersion. [0003] In the prior art, in order to achieve a 360-degree stereoscopic effect, there are two implementation methods: [0004] 1. The binocular camera is used to move along the circular track, and the 360-degree stereoscopic video...
