Problems solved by technology

The existing technology is to pre-process the jitter through software anti-shake technology, but the hardware itself has not been significantly improved, which cannot fundamentally remove the influence of jitter, and also increases the difficulty for subsequent AR image processing

Abstract

The embodiment of the invention provides an AR imaging method, a device and electronic equipment. The method comprises the following steps: detecting a face image taken by a mobile terminal and extracting a sub-image of a nose region in the face image; determining a light intensity weighting center of the sub-image based on the light rays, comparing the light intensity weighting center with the weighting center of the face image to obtain a light estimation angle; obtaining a ray angle of a real scene according to the ray estimation angle and the rotation angle of the mobile terminal, whereinthe real scene is the real world currently photographed by the mobile terminal; a shadow image of the virtual object is generated according to a light angle of the real scene and a preset position ofthe virtual object in the real scene. No additional hardware is required, and only the mobile terminal using the existing dual-camera can obtain the light information in the real world, which providesmore realistic effect for AR, reduces the cost and requires low performance for the mobile terminal equipment.

Description

technical field [0001] The present invention relates to the field of augmented reality technology, in particular to an AR imaging method, device and electronic equipment. Background technique [0002] A common problem in computer vision, especially in augmented reality applications, is the detection of the intensity and direction of light that affects the imaging of virtual objects. Existing light detection algorithms generally rely on specific sensors and hardware, or make assumptions about the position and time of light sources (such as the sun or moon) based on environmental information in the scene. In the field of augmented reality applications, the estimation of light information mainly focuses on light intensity and hue. It only calculates the average brightness of the entire real scene image, rather than the actual ambient light direction, which has nothing to do with the actual position of the real scene light source. It does not provide enough information guarante...
