Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039]The first embodiment of the present invention provides an exposure method S10 based on scene depth to solve the situation of exposing objects to be exposed based on scene depth in the field of intelligent visual recognition.

[0040] In the present invention, the depth of scene refers to the clear range before and after the focus. The farther the depth of scene is, the clearer the whole image will be from the distant view to the near view; Blur to make the subject stand out more. The focal point physically refers to the converging point where parallel light rays are refracted by a lens o...

Abstract

The invention relates to the field of intelligent visual recognition, in particular to an exposure method and system based on scene depth and an electronic device thereof. The exposure method based onthe scene depth includes the following steps: obtaining a depth map of a to-be-exposed scene, and obtaining a mask map by comparing the sizes of depth values of corresponding pixel points in the depth map; calculating the depth values of all pixel points in the depth map corresponding to the mask map to obtain corresponding weight maps; and adjusting the exposure value of the to-be-exposed scenebased on the weight maps. The exposure method based on the scene depth provided by the invention can carry out exposure value adjustment according to the scene requirements, has a small calculation amount, is especially suitable for the field of intelligent containers, and further achieves the exposure adjustment of the characteristic parts of commodities for sale.

Description

【Technical field】 [0001] The invention relates to the field of intelligent visual recognition, in particular to a method, system and electronic device for setting an image change area detection threshold. 【Background technique】 [0002] Now the new retail industry is gradually emerging, and unmanned containers have also been widely promoted. At present, the unmanned containers on the market can identify the products displayed on the container through the product pictures. Therefore, it is particularly important to clearly and accurately obtain the product pictures. Whether the exposure is normal during the image acquisition process directly affects the effect of the image; overexposure, the image looks too bright, and underexposure, the image looks too dark, and the exposure value directly affects the accuracy of image recognition. [0003] Existing exposure methods are mainly divided into two schemes: global statistics or local weighted statistics. Global statistics is a ...
