Problems solved by technology

In order to avoid the poor viewfinder effect caused by the shaking of the handheld device, or the inconvenience caused by the user holding the mobile phone for a long time to watch the video, it is often necessary to install the mobile phone on a bracket to keep it stable. Ordinary users often use a simple mobile phone bracket to achieve the required The viewfinder effect and stable support effect, while the usual simple bracket is located on the mobile phone protective case, or pasted on the back of the mobile phone with super glue, more and more users are due to the increasingly strong mobile phone glass, mobile phone heat dissipation, and mobile phone aesthetics. Instead of using a phone case and an adhesive simple stand

Abstract

The embodiment of the invention provides an optimization method and device of illumination information, and electronic equipment. The method comprises the following steps: acquiring a target picture,decomposing the target picture into a first preset amount of sub-pictures; acquiring a geometric center of each sub-picture, and determining a light intensity weighting center according to an image moment center of the sub-picture, and determining the illumination angle of the sub-picture according to the light intensity weighting center and the geometric center of the sub-picture; performing grayprocessing on the sub-picture, and obtaining the illumination intensity of the sub-picture according to the gray value of each point on the sub-picture; acquiring the illumination intensity weight value of the sub-picture, and obtaining the illumination intensity of the target picture according to the illumination intensity of the sub-picture and the illumination intensity weight value of the sub-picture; and obtaining the illumination angle of the target picture by computing the illumination angle of the sub-picture.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a lighting information optimization method, device and electronic equipment. Background technique [0002] Augmented Reality (AR for short) technology can put the virtual world on the screen and interact with the real world. Users can perceive the existence of virtual objects by using AR devices. However, in the process of implementing the present invention, the inventors found that in related technologies, it is generally necessary to obtain the environmental information, location and time of the picture or video in advance, and determine the lighting information corresponding to the picture or video through the above information, and then observe the virtual object. rendering of shadow effects. The above methods are not only inefficient, but also may cause deviations between the light and shadow effects of the virtual object and the scene due to the inability ...
