AI Technical Summary

Technical Problem

In the traditional external parameter calibration method, the tire pressure value changes frequently and the amplitudes vary, resulting in changes in the camera's external parameter, affecting the surround view splicing effect.

Method used

Through the dynamic surround view splicing method based on tire pressure monitoring, the tire pressure value is quantified using preset vehicle information, a mapping relationship table of tire pressure data segments is constructed, and matching and searching is performed based on real-time tire pressure data to realize surround view splicing.

Benefits of technology

The calculation amount caused by changes in tire pressure value is reduced, the speed and accuracy of circumferential splicing are improved, and the external parameter drift problem is avoided due to changes in tire pressure.

Abstract

The invention provides a dynamic look-around splicing method and system based on tire pressure monitoring, and the method comprises the steps: carrying out the quantitative processing of a tire pressure value according to the preset vehicle information of a target vehicle, so as to obtain a tire pressure data segment array of the target vehicle; the tire pressure data segment array comprises a plurality of tire pressure data segments; according to each tire pressure data segment, respectively constructing a mapping relation table of each tire pressure data segment to obtain a total mapping relation table; performing matching search according to the real-time tire pressure data of the target vehicle and the total mapping relation table to obtain a target mapping relation table of the real-time tire pressure data; and performing all-round stitching of the target vehicle according to the target mapping relation table. By quantifying the tire pressure value in the tire pressure monitoring system, the calculation amount of the Map mapping lookup table caused by frequent change of the tire pressure value is reduced, and the calculation amount of subsequently establishing the tire pressure value and the Map mapping lookup table is also reduced.
