Embodiment
[0023] Such as figure 1 As shown, a method for calculating the minimum number of LED lights required by a VR camera, including steps:
[0024] (a) Set a mark point that can reflect the light intensity of the VR camera;
[0025] (b) The VR camera emits light, which is captured by the marked point and reflected to the VR camera to obtain the minimum light intensity required for the marked point. The light reflected from the marked point to the VR camera needs to reach the minimum light intensity that the VR camera can recognize the marked point ;
[0026] Specifically, the minimum accepted light intensity required by the marking point is obtained by the following steps:
[0027] (b1) From the minimum light intensity accepted by the VR camera and the farthest distance between the mark point and the VR camera, the minimum reflected light intensity required for the mark point is obtained;

The invention discloses a method for calculating number of least required LED lamps for a VR camera. The method comprises the steps of (a), setting a mark point which reflect light strength of the VRcamera; (b), emitting light from the VR camera, capturing the light and reflecting the light to the VR camera by the mark point, and acquiring a required least receiving light strength of the mark point; (c), back-deriving the equivalent light strength of the VR camera according to the longest distance between the mark point and the VR camera and the required least receiving light strength of themark point; and (d), calculating the number of least required LED lamps for the VR camera according to the equivalent light strength of the VR camera. According to the method of the invention, based on a light propagation mode in motion capturing, the number of the least required LED lamps for a field is determined according to the light strength change. The method of the invention is suitable forselecting the VR camera after the field is determined. The method can supply a basis for reasonably selecting the VR camera, thereby reducing cost, waving energy and realizing environment-friendly performance.
Description
technical field [0001] The invention relates to a method for calculating the minimum number of LED lights required by a VR camera. It belongs to the field of VR. Background technique [0002] For a fixed venue, a certain number of LED lights in the VR camera can satisfy the venue; if the venue changes, the number of LED lights will also change accordingly. However, the existing application status is generally the number of LED lights of the fixed VR camera, so there is a hidden danger, the number of LED lights may exceed the number required by the site, increasing the cost; it may also be lower than the number required by the site, increasing some areas of the site Risk of losing markers. Contents of the invention [0003] The purpose of the present invention is to overcome the above defects and provide a method for calculating the minimum number of LED lamps required by a VR camera. Solve the problem of poor site adaptability caused by the fixed number of LED lights in...
