摘要

In order to solve the problem of illumination consistency in Augmented Reality, a method of realtime render virtual object based on HDR image is proposed in this paper. According to the camera imaging function, the HDR image is generated by using normal camera, and is fast generated by limiting dynamic range and reducing the exposure time. The light source information and radiance map are obtained on the basis of the pixel value and location of the generated HDR image, and are used to render the virtual object The virtual object is displayed by using tone mapping technology. Experiments demonstrate that the system can realtime update HDR image when the illumination environment changed dynamically, so that the virtual object have ideal shade and shadow effects.
