Embodiment 1

[0028] A method for identifying and locating people and robots based on an intelligent optical fiber floor, comprising the following steps:

[0029] S1: if figure 1 As shown, the indoor floor is divided into N×N grids, N is a positive integer, and the size of each grid is LxL cm 2 . Assuming that a person or robot can only be in one grid at a certain moment, this grid is the position of the target. For the convenience of representation, the ijth grid represents the grid in the i-th row and j-th column on the floor.

[0030] S2: According to the floor grid division, lay M optical fiber sensors in the grid, where M is a positive integer.

[0031] S3: Construct the optical fiber sensor measurement model: use an M-bit code y to represent the output of M optical fiber sensors, wherein the nth bit y(n) represents the output of the nth optical fiber sensor, n=1...M; the output of the optical fiber sensor y(n) takes values ​​in {0,1,2}; y(n)=0 means that the nth fiber optic sensor...

Abstract

The invention discloses a human and robot identification and location method based on an intelligent optical fiber floor. The identification and location method comprises the steps of dividing the floor into N*N grids, wherein N is a positive integer; laying M optical fiber sensors into the grids according to the grid partitioning of the floor, wherein M is a positive integer; building an optical fiber sensor measurement model, wherein in the model, the three conditions that the optical fiber sensors are not triggered, are triggered by a robot, and are triggered by a person or by a person and a robot at the same time correspond to different output values; building a unique decodable mark so as to enable the only output of the M optical fiber sensors to correspond to a person and a robot in any grid; according to the total output of the M optical fiber sensors, looking up a table to obtain i1j1 and i2j2, namely, the grids in which a person and a robot are positioned. The method is suitable for identifying and locating a human and a robot indoors in the smart home field, and has the advantages of being high in environmental adaptation, easy to operate, sensitive in detection, etc.

Description

technical field [0001] The invention relates to the field of smart home, and more specifically, to a method for identifying and locating humans and robots based on an intelligent optical fiber floor. Background technique [0002] Smart homes provide people with smart services to improve their quality of life and increase their ability to live independently. Indoor target positioning is an important basis for realizing smart home technology. Currently commonly used indoor target positioning methods are mainly based on computer vision, pyroelectric infrared sensors and radio frequency identification. [0003] For indoor target positioning, the orientation measurement based on computer vision needs to use algorithms with high computational complexity to extract orientation information from redundant image data, and these algorithms are extremely sensitive to changes in illumination and background, and involve personal privacy issues. Measurement methods based on pyroelectric ...
