Embodiment Construction

[0022] In the drawings, the same or similar reference numerals are used to denote the same or similar elements or elements having the same or similar functions. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] The method for detecting the symmetry of seat body pressure distribution according to the present invention includes:

[0024] Step 1: Obtain body pressure distribution map;

[0025] Step 2: Read the number of rows and columns of the body pressure distribution map;

[0026] Step 3: Read the location coordinates of all maximum pressure values ​​in the body pressure distribution map, and record the total number;

[0027] Step 4: If the total number obtained in the above step 3 is an odd number, it is determined that the body pressure distribution of the seat is asymmetrical and ends; otherwise, the position coordinates of the maximum pressure value and the body pressure centerline are displayed...

Abstract

The invention discloses a method for detecting the body pressure distribution symmetry of a seat. The method comprises the steps of 1, acquiring a body pressure distribution graph; 2, reading the row number and the column number of the body pressure distribution; 3, reading the position coordinates of maximum pressure values in the body pressure distribution graph and counting the total number of maximum pressure values; 4, on the condition that the total number is an odd number, determining the body pressure distribution of the seat to be in the asymmetrical state and stopping the process; otherwise, displaying the position coordinates of the maximum pressure values and the center line of the body pressure in a two-dimensional graph; 5, on the condition that the maximum pressure values are on one side of the center line of the body pressure or the numbers of the maximum pressure values on the two sides of the center line are not equal in the two-dimensional graph obtained in the step 4, judging the body pressure distribution of the seat to be in the asymmetrical state and stopping the process; otherwise, calculating the body pressure distribution symmetry of the seat and quantizing the determined body pressure distribution symmetry of the seat. According to the technical scheme of the invention, on the basis of the measured body pressure distribution of the seat, the body pressure distribution symmetry of the seat can be intuitively and accurately detected through the image processing process.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for detecting the symmetry of seat body pressure distribution. Background technique [0002] Existing methods for detecting the symmetry of seat body pressure distribution cannot intuitively and accurately determine the symmetry of seat body pressure distribution.
