Method, device and electronic equipment for determining light information

Abstract

Examples of the present invention provide a method, device and electronic device for light information, which include: obtain the target picture, decompose the target picture into the first preset number of sub -pictures, where the sub -picture is from the sub -picture fromThe pixel composition of the second preset quantity; determine the light intensity of the sub -picture, and calculate the image torque to determine the light weighted center of the sub -picture;The geometric center determines the light angle of the sub -picture; calculates the light intensity and light angle of the sub -pictures, and obtains the light information corresponding to the target picture.There is no need to obtain the environmental information, location and time of pictures or videos, nor do you need to collect and label the face image or other specific hardware resources.In areas without light, this method can also be used to obtain light intensity.Compared with existing technology, the cost of the present invention is low, and it is more convenient and accurate.

Description

Technical field [0001] The present invention relates to the field of image processing technology, in particular to a method, device and electronic equipment for determining light information. Background technique [0002] Augmented Reality (AR) technology is a technology that calculates the position and angle of the camera image in real time and adds corresponding images, videos, and 3D models to 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 inventor found that in the related technology, since virtual objects are generated in advance by a computer, it is impossible to obtain the environment information of the scene during use by the user, or it is impossible to accurately detect the light intensity and light intensity of the scene. Direction, so it cannot match the scene in the video or the real world. [0003] In addi...

Problems solved by technology

In order to avoid poor framing effect caused by the shaking of the handheld device, or the user’s physical strength caused by watching videos with the mobile phone for a long time, it is often necessary to install the mobile phone on a fixed bracket to keep it stable. The special camera bracket is quite effective, but it is expensive and common Users often use simple brackets for mobile phones to achieve the desired viewfinder effect, and the usual simple brackets are located on the protective case of the mobile phone or pasted on the back of the mobile phone with strong glue. problems, phone aesthetics rather than using a phone case and sticky simple stand
