Abstract

The embodiment of the invention provides a soft shadow processing method and device for augmented reality equipment. The method comprises the steps that a motion vector of augmented reality equipmentis acquired, a first motion vector of an AR scene camera of the augmented reality equipment is acquired according to the motion vector, and the AR scene camera moves along with movement of the augmented reality equipment; a second motion vector of the shadow camera is determined according to the first motion vector; and after the shadow camera is controlled to move the second movement vector, a shadow map is generated, wherein the shadow map generated after the shadow camera moves the second movement vector is compared with the shadow map generated before the shadow camera moves the second movement vector, an integer number of pixels are moved, and an image frame is generated and output according to the shadow map. According to the method provided by the embodiment of the invention, the flicker of the soft shadow edge when the AR equipment moves is eliminated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a soft shadow processing method and device for an augmented reality device. Background technique [0002] In augmented reality (Augmented Reality, referred to as: AR) applications, it is necessary to superimpose the virtual scene and the real scene. The real scene comes from the photos of the real scene taken by the camera, and the virtual scene is usually represented by some models. If the model is directly superimposed on the scene In the photo, there will be obvious dissonance due to the lack of shadows. In order to enhance the reality of the AR scene, shadows can be added to the AR scene. Furthermore, the soft shadow (Soft Shadow) technology can be used to create a virtual effect around the shadow, so as to simulate the shadow gradient in the real scene, and further enhance the realism of the AR scene. [0003] The existing shadow algo...
