[0046] For this type of infrared ranging sensor, the relationship between the data input into the single-chip microcomputer and the distance of the obstacle directly in front can be fitted as an inverse proportional function, and the detected original data is set as value, then the segmented function (when value<30, f( value)=30; when value≥30, f(value)=[67870.0 / (value-3.0)]-40.0) after processing, the processed data f(value) is positively correlated with the obstacle distance at 10-80cm .
[0047] A certain experimental data processing process: At this time, the car is relatively close to the obstacle on the left, and the initial data obtained by the single-chip microcomputer is 143 left rear, 114 left front, 30 right rear, and 35 right front; firstly, the obstacle is obtained by processing the function f(value) Distance parameters: At this time, the left rear distance parameter is 434, the left front distance parameter is 571, the right rear distance parameter is 2473, and t...
