Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Please refer to figure 1 , the embodiment of the present invention provides a service robot active service method based on the degree of drowsiness, using this method, the robot can actively provide corresponding services for the user according to the user's needs, including the following step:

[0035] A1: Use the PERCLOS indicator to determine the user's sleepiness.

[0036]

[0037] Among them, t i Indicates the duration of human eye closure, n represents the time window is t i The number of times the person closes their eyes generated within T is the length of the entire time window.

[0038] In order to obtain n in PERCLOS, it is first necessary to take a picture of the user. This embodiment takes video shooting and picture taking of t...

Abstract

The invention provides a service robot active service method based on sleepiness degree, comprising the following steps: A1, judging sleepiness degree of a user by using PERCLOS index; A2: obtain thatfuzzy relationship between the sleepiness degree of the user and the us's demand from the beginning to the time when the sleepiness degree is generated; A3: The robot actively provides correspondingservice for the user according to the fuzzy relation. The invention has the beneficial effects of enabling the robot to actively provide the corresponding service for the user according to the requirement of the user and under the condition that the user does not send out instructions, thereby contributing to the improvement of the learning and working efficiency of the user.

Description

technical field [0001] The invention relates to the technical field of service robots, in particular to an active service method for a service robot based on drowsiness level. Background technique [0002] As service robots enter every aspect of daily life, people have put forward higher requirements for robots. Traditional service robots basically use command-time services, but now people expect robots to have the ability to perceive human emotions and intentions and actively serve people. Therefore, it is an important breakthrough to improve the intelligence of service robots to enable robots to perceive the surrounding environment, understand human emotions, intentions and service needs, and provide active and high-quality services according to user needs and changes in environmental information. [0003] Drowsiness is a state that accompanies physical or mental fatigue. The appearance of drowsiness will reduce people's alertness, decision-making ability and memory to a...
