Description
Technical field
The present invention relates to a kind of methods of minimum LED light quantity needed for calculating VR camera.Belong to the field VR.
Background technique
For fixed venue, in VR camera, LED light, which reaches certain amount, can meet the place；If place converts, LED
Lamp quantity can also change correspondingly.But the existing LED light quantity that fixed VR camera is generally using status, thus has one
A hidden danger, LED light quantity may be more than place requirement, increase cost；Place requirement may also be lower than, increase field
The risk of ground partial region loss marker point.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, a kind of side for calculating minimum LED light quantity needed for VR camera is provided
Method.Solve the problems, such as in existing VR camera LED light quantity fix and caused by place bad adaptability.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A method of minimum LED light quantity needed for VR camera is calculated, is included the following steps:
(a) mark point that can reflect VR camera light intensity is set；
(b) VR camera issues light, captures light by mark point and is reflected into VR camera, minimum needed for obtaining mark point receives light
By force；
(c) by mark point and VR camera maximum distance, minimum needed for binding marker point receives light intensity, it is counter push away VR camera etc.
Imitate light intensity；
(d) minimum LED light quantity needed for VR camera is calculated as the equivalent power of VR camera.
Specifically, the light for being reflected into VR camera by mark point need to reach the minimum light of VR camera identifiable marker point
By force.
Further, in the step (b), minimum needed for obtaining mark point receives the acquisition process of light intensity are as follows:
(b1) light intensity and mark point and VR camera maximum distance are received by VR camera minimum, minimum needed for obtaining mark point
Reflective light intensity；
(b2) by mark point reflection coefficient, minimal reflection light intensity needed for binding marker point, minimum needed for obtaining mark point is connect
By light intensity.
The calculation formula of minimum LED light quantity needed for the VR camera are as follows:
Wherein, NminFor least LED light quantity, L needed for VR cameramaxFor mark point and camera maximum distance；R is label
Reflection coefficient of the point to light；R is mark point radius；IledFor single led lamp luminous intensity；IminLight is subjected to for VR camera minimum
By force.
The mark point is the round reflector that radius is r.
Compared with prior art, the invention has the following advantages:
The present invention is based on light propagation modes in movement capture, determine minimum number needed for place by the variation of light intensity
LED light, the selection of VR camera after determining suitable for place, the present invention, which can provide foundation for reasonably selection VR camera, reduces cost
Waste, it is energy saving, support environmental protection.
Detailed description of the invention
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
Embodiment
As shown in Figure 1, a kind of method for calculating minimum LED light quantity needed for VR camera, comprising steps of
(a) mark point that can reflect VR camera light intensity is set；
(b) VR camera issues light, captures light by mark point and is reflected into VR camera, minimum needed for obtaining mark point receives light
By force, the minimum intensity of light of VR camera identifiable marker point need to be reached by the light that mark point is reflected into VR camera；
Specifically, minimum needed for obtaining mark point as following steps receives light intensity:
(b1) light intensity and mark point and VR camera maximum distance are received by VR camera minimum, minimum needed for obtaining mark point
Reflective light intensity；
(b2) by mark point reflection coefficient, minimal reflection light intensity needed for binding marker point, minimum needed for obtaining mark point is connect
By light intensity.
(c) by mark point and VR camera maximum distance, minimum needed for binding marker point receives light intensity, it is counter push away VR camera etc.
Imitate light intensity；
(d) minimum LED light quantity needed for VR camera is calculated as the equivalent power of VR camera.
The calculation formula of minimum LED light quantity needed for VR camera are as follows:
Wherein, NminFor least LED light quantity, L needed for VR cameramaxFor mark point and camera maximum distance；R is label
Reflection coefficient of the point to light；R is mark point radius；IledFor single led lamp luminous intensity；IminLight is subjected to for VR camera minimum
By force.The mark point is the round reflector that radius is r.
According to above-described embodiment, the present invention can be realized well.It is worth noting that before based on above-mentioned design principle
It puts, to solve same technical problem, even if that makes in structure basis disclosed in this invention is some without substantive
Change or polishing, the essence of used technical solution is still as the present invention, therefore it should also be as in protection model of the invention
In enclosing.
