Description
Technical field
The present invention relates to a kind of field of virtual reality, particularly relate to the laying method of a kind of VR panoramic camera camera lens.
Background technology
Virtual reality technology is a kind of can establishment and the computer simulation system in the experiencing virtual world, and it utilizes computer
Generate interactively Three-Dimensional Dynamic what comes into a driver's and the system emulation of entity behavior that a kind of simulated environment is a kind of Multi-source Information Fusion
User is made to be immersed in this environment.Virtual reality technology (VR) mainly includes that simulated environment, perception, natural technical ability and sensing set respectively
Etc. aspect.Simulated environment is generated by computer, the 3 D stereo photorealism of Real-time and Dynamic.Perception refers to that preferable VR should
This has the perception that all people are had.In addition to the visually-perceptible that computer graphics techniques is generated, also audition, sense of touch, power
The perception such as feel, motion, the most also include olfactory sensation and the sense of taste etc., the most perception.Natural technical ability refers to the head rotation of people, eye
Eyeball, gesture or other human body behavior acies, processed, by computer, the data that the action with participant adapts, and to user
Input make real-time response, and feed back to the face of user respectively.
When shooting VR video, especially during the three-dimensional VR video of shooting, it would be desirable to use at least 2 or 4 cameras,
Each camera includes a camera lens, for 360 degree of video images within the vision of shooting, is positioned at not coordination to each the most again
The two field picture of the camera synchronization shooting put carries out splitting, splicing.
VR video camera the most on the market, is assembled by some mm professional camera specials.
During nodal distance minimum between adjacent imaging device, the seam between VR panoramic camera image is the least, figure
As effect is the best.Amass relatively large in view of existing camera and its lens body, when the arranged distribution of camera, it would be desirable to
Consider following 2 points: one is owing to the volume of camera is fixing, so when the arranged distribution of camera, it would be desirable to by minimum
The VR panoramic camera lens assembly of volume goes to place camera lens so that the nodal distance of adjacent cameras is minimum, meets simultaneously and carries
Convenience；Two be parallax between the nodal distance human body to be met two of adjacent cameras camera lens away from, in order to form parallax.
Summary of the invention
In order to solve above technical problem, the present invention proposes the laying method of a kind of VR panoramic camera camera lens.
The present invention solves that its technical problem be employed technical scheme comprise that,
The laying method of a kind of VR panoramic camera camera lens, sets including Liang Tai and more than two imagings arranged in alternating expression
Standby, described imaging device is provided with a camera lens, and the node of described camera lens is positioned on same circumference, and the node of each imaging device
Extension line is through the center of circle of described circumference.
Owing to the shooting node of all camera lenses is positioned on same circumference, and the extension line of each camera lens node is through described circle
The center of circle in week so that the field range of shooting can cover 360 degree of panoramic range.Place in alternating expression between imaging device, phase
For the direct splicing between imaging device, the pitch between adjacent camera lens is less so that Panorama Mosaic seam is little, viewing
Effect is more preferable, the most also can effectively reduce the volume of video camera.
Further, the number of imaging device is 2, and described imaging device is that alternating expression is distributed back-to-back.
Further, the number of imaging device is 4.
Further, the number of imaging device is 6.
Further, described camera lens is fish eye lens.
Further, the camera lens Radix Rumicis of described imaging device is more than 180 degree.
Further, described camera lens is fish eye lens.Select fish eye lens or camera lens Radix Rumicis can make the visual field more than 180 degree
Scope is the broadest.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Close diagram and specific embodiment, the present invention is expanded on further.
Embodiment 1:
As it is shown in figure 1, for the VR video camera that is made up of 4 cameras on the market, by first camera 11, second camera 12, the
Three camera the 13, the 4th cameras 14 assemble, and four cameras are arranged in order one square shape of composition, the Inner Constitution of camera
One square ABCD, it is assumed that the length of side (wide) of camera is m, a height of n, the most foursquare length of side is m.Assume that 11O is the first phase
The shooting node of machine 11,12O is the shooting node of second camera 12, and the distance of nodal distance camera is f, and node 11O is to node
The pitch of 12O is
As shown in Fig. 2 a, 2b, VR panoramic camera, including 4 imaging devices, it is respectively as follows: first camera 21, second camera
22, third camera the 23, the 4th camera 24, each camera includes a camera lens, the respectively first camera lens 21b, the second camera lens 22b,
Three-lens 23b, the 4th camera lens 24b.The angle close to 90 degree is formed between adjacent camera lens.Arrange in alternating expression between adjacent cameras
Row so that the shooting node of four cameras is positioned on same circumference, and the extension line of the shooting node of each camera is through upper
State the center of circle of circumference.
Four camera internal constitute a square A ' B ' C ' D ', it is assumed that the foursquare length of side is that 2s, 2s are far smaller than phase
