Embodiment Construction

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] In order to solve the problem of high cost of estimating distance in the prior art and inability to distinguish whether it is a face or not, in this embodiment of the present invention, an image collected by a camera on a terminal is acquired, and according to a preset face recognition algorithm, it is determined that the Whether a face is detected, if it is determined to be detected, the size of the face is calculated, and based on...

Abstract

The present invention relates to the field of intelligent terminals, in particular to a method and device for distance estimation and processing based on face detection. , when it is determined that a human face is detected on the image, calculate the distance between the human face and the camera; when it is determined that the distance between the human face and the camera conforms to a preset rule, perform a corresponding processing operation. The camera of the terminal collects images, and according to the face recognition algorithm, detects whether it is a human face, and then calculates the distance between the face and the camera according to the size of the face, without additional hardware equipment, reducing costs, and can distinguish whether it is a human face, And when it is determined that the distance between the face and the camera conforms to the preset rules, corresponding processing is performed, which solves the problem that the user is too close to the screen to easily cause visual impairment when viewing the content on the screen on the terminal.

Description

technical field [0001] The present invention relates to the field of intelligent terminals, and in particular, to a method and device for distance estimation and processing based on face detection. Background technique [0002] Users, especially children, are prone to get too close when viewing content on a small screen through a terminal, which will lead to visual impairment of the user. , In the existing smart phones and visual robots, various sensors are generally used to perceive the distance. There are mainly several types: 1) using a proximity sensor; 2) using an infrared or ultrasonic distance sensor; 3) using a binocular camera for depth measurement. [0003] However, in the prior art, although a proximity sensor, infrared or ultrasonic distance sensor can be used to measure the distance to an object, additional hardware equipment is required, and it cannot distinguish whether the object is a human face or not. In the prior art, using a binocular camera to measure ...
