Abstract
A method, a mixed reality (MR) system, and a recording medium for detecting a real-world light source in MR are provided. The method is applicable to the MR system having a computing apparatus and a head-mounted display (HMD). In the method, a plurality of light regions of a plurality of continuous images is analyzed, and each of the light regions is projected according to a coordinate position of the HMD corresponding to the plurality of continuous images to generate three-dimensional vectors. Then, the three-dimensional vectors are clustered to predict a directional light in a current image. Finally, a plurality of intersection points between the three-dimensional vectors is calculated, and a point light in the current image is predicted according to the intersection points.
