US 2019/0056479 A1 · SYSTEM AND METHOD FOR VEHICLE RADAR INSPECTION

Abstract

The present disclosure provides a system and method for a vehicle radar inspection. A system for inspecting an assembled state of a radar sensor mounted in a vehicle may include a center portion configured to align the vehicle to a reference inspection position; a mobile terminal configured to connect with an external source of communication; a scan portion configured to photograph the radar sensor at a plurality of scan positions using a terahertz wave; and a server configured to match a plurality of scan images photographed by the scan portion, to detect a three-dimensional coordinate of the radar sensor, to transmit a sensor correction value through the mobile terminal, wherein the sensor correction value is determined based on an assembly tolerance that compares with a design plan of the vehicle, and to correct a sensor angle value of the radar sensor.

Dependent claims

A system for inspecting an assembled state of a radar sensor mounted in a vehicle, the system comprising:

a center portion configured to align the vehicle to a reference inspection position;
a mobile terminal configured to connect with an external source of communication, wherein the mobile terminal is connected to a communication line within the vehicle;
a scan portion configured to photograph the radar sensor at a plurality of scan positions using a terahertz wave;
and
a server configured to:
match a plurality of scan images photographed by the scan portion;
detect a three-dimensional coordinate of the radar sensor;
transmit a sensor correction value through the mobile terminal, wherein the sensor correction value is determined based on an assembly tolerance that compares with a design plan of the vehicle;
and
correct a sensor angle value of the radar sensor.

A method for inspecting an assembled state of a radar sensor mounted in a vehicle by a server installed on an inspection line, the method comprising:

connecting communication with a mobile terminal that is connected to the vehicle;
aligning, with a center portion, the vehicle to a reference inspection position, wherein the center portion is installed on the inspection line;
moving a terahertz wave scanner to a first scan position to photograph a first scan image and moving the scanner to a second scan position to photograph a second scan image;
recognizing a three-dimensional coordinate of a stereoscopic image that is generated by matching the first scan image and the second scan image;
generating a sensor correction value based on an occurrence of assembly tolerance when the three-dimensional coordinate of the stereoscopic image does not match a design plan of the vehicle;
and
transmitting, with the mobile terminal, the sensor correction value to the radar sensor.
