Abstract: Implementations of the subject matter described herein relate to mixed reality rendering of objects. According to the embodiments of the subject matter described herein, while rendering an object, a wearable computing device takes lighting conditions in the real world into account, thereby increasing the reality of the rendered object. In particular, the wearable computing device acquires environment lighting information of an object to be rendered and renders the object to a user based on the environment lighting information. In this way, the object rendered by the wearable computing device can be more real and accurate. The user will thus have a better interaction experience.

Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution of lighting estimation. In the solution, an input image about a real object and a depth map corresponding to the input image are obtained. A geometric structure of the scene in the input image is determined based on the depth map. Shading and shadow information on the real object caused by a light source in the scene is determined based on the determined geometric structure of the scene. Then, a lighting condition in the scene caused by the light source is determined based on the input image and the shading and shadow information. The virtual object rendered using the lighting condition obtained according to the solution can exhibit a realistic effect consistent with the real object.
