Embodiment Construction

[0024] This technology uses a digital camera to capture high-dynamic light information in a specified real environment, and simultaneously collects 4π omnidirectional solid angles. The data is imported into a computer for integration.

[0025] see figure 1 , place the camera in the specified real environment, and do 4π omni-directional solid angle data collection at the same time. Connect the camera to the computer

[0026] see figure 2 , the specific steps are:

[0027] (1) Design the lighting environment and design the lighting according to the conditions required by virtual reality.

[0028] (2) Simulate the lighting environment required by virtual reality in the real environment. The specific implementation is divided into indoor and outdoor two situations.

[0029] (3) Adjust the direction of the camera, the focal length, the exposure, and shoot. A total of six directions need to be shot, with three different exposures in each direction, high, medium and low, for ...

Abstract

The invention relates to a technology which collects light information in real environment and applied in virtual reality. The invention is technically characterized by not using artificial light or artificial light dot matrix to directly light, but collecting light information directly from real environment to implement indirect lighting. The invention aims at showing real, accurate and rich light effect in virtual reality. The technical scheme mainly includes the following operation steps: taking a digital camera as a centre of sphere, shooting to six directions including up and down, front and back as well as left and right (different exposure respectively means high exposure, normal exposure and low exposure), combining with the six directions to shoot eighteen digital images, using 32bit data storage format to completely keep the light information in the real environment during the integration process of computers, and finally applying the lighting information into a virtual world.

Description

1. Technical field: [0001] The invention is a method for performing real lighting on virtual reality, and mainly relates to the fields of virtual reality and computer graphics and imaging. 2. Background technology: [0002] The existing method of lighting virtual reality is to use artificial light or artificial light dot matrix lighting for direct lighting. The main disadvantage is that it is difficult to obtain real effects, or the cost of calculation time is too high. 3. Contents of the invention: [0003] The present invention solves the deficiencies in the above-mentioned background technology, and provides a method for collecting lighting information in real scenes and applying it to virtual reality. Take light from the environment for indirect lighting. The lighting information obtained by it is accurate and rich, and can reflect the real effect in virtual reality. [0004] To achieve the above object, the technical solution adopted in the present invention is: ...
