System and method for watching unlocking robot by eyes

Abstract

The invention discloses an eye gaze unlocking robot system. The system comprises a human body detection unit, an image acquisition unit and a central processing unit, wherein the human body detectionunit and the image acquisition unit are respectively connected with the central processing unit, and the central processing unit comprises a face detection module, a gaze detection module and a control module. The invention further discloses a method for unlocking the robot through eye gaze, an awakening mode is added, a powerful supplement is formed, and the robot is made to be intelligent; the robot is unlocked very quickly, naturally and intelligently by using the unlocking method disclosed by the invention; when a user watches the face of the robot, the robot can be activated within 2 meters. In the robot awakening process, a gaze judgment method is introduced, and awakening caused by mistaken entering of a user is reduced; for a concerned user, the robot can be automatically unlockedimmediately, and the user feels good.

Description

technical field [0001] The present invention specifically relates to a system and method for watching an unlocking robot with eyes. Background technique [0002] In order to reduce power consumption and prolong the life of the screen, turning on the screen for a long time will cause the aging of the backlight LED tube and partial ablation of the screen, so the robot system will be locked. [0003] At present, the robot is in the locked / sleep / standby / low power consumption state, and the unlocking methods are as follows: [0004] (1) Human body infrared sensing method: When the infrared sensor loaded on the robot receives a human body approach signal, it generates a human body approach signal and notifies it to the main program of the robot, and the main program wakes up the robot. [0005] (2) Face detection method: Real-time detection of the environment through the high-definition camera assembled by the robot. When the movement of people in the field of view is detected a...

Problems solved by technology

[0007] In actual work, it is found that various wake-up technologies have certain shortcomings, for example, (1) Infrared sensing method: when a person enters a distance of 1.5 meters, an alarm is generated and the machine is unlocked

If a person walks around the machine, just strolling, there will be a lot of false alarms and false unlocks, and it will be embarrassing if the voice is broadcast every time

(2) Face detection method: A person just looks at the machine casually, and the face detection algorithm can pass the detection, and it will be unlocked, which is also unlocked by mistake; and the face detection method needs to identify the personnel information, which needs to be entered in advance. People who don't need to use the system can't judge

(3) Voice wake-up method: easy to be affected, easy to be woken up by mistake; and when the user needs the robot to provide services, first call the robot by name, wake up, the feeling is a little worse, and the user experience is not good

[0008] When there are many actual scenes: visitors come in and arrive at the robot service area, but the robot unlock service is not required. When visitors need to use the robot, the first reaction is to go to see the robot. The above-mentioned method of unlocking the robot cannot meet this kind of demand.
