Abstract
A system for inspecting a LIDAR sensor for correcting an error of the LIDAR sensor in a vehicle includes: a centering unit which aligns the vehicle equipped with a communication terminal to match a reference inspection position of the LIDAR sensor; screen panels miniaturized so that an uppermost end point of a LIDAR beam according to an irradiation angle of the LIDAR sensor is projected on a center portion of the screen; a Near Infrared camera which captures the LIDAR beam; and a server which detects an installation error in which the uppermost end points of the LIDAR beams are different, generates a sensor correction value, and transmits the sensor correction value to the LIDAR sensor.
Claims20
A system for inspecting a LIDAR sensor for correcting an error of the LIDAR sensor installed in a vehicle, the system comprising:
- a centering unit which aligns the vehicle entering an inspection process to match a reference inspection position of the LIDAR sensor;
- a plurality of screen panels installed at a set distance and a set height with respect to the LIDAR sensor and sized so that an uppermost end point of a LIDAR beam according to an irradiation angle of the LIDAR sensor is projected on a center portion of each of the screen panels;
- a Near Infrared (NIR) camera which captures the LIDAR beam projected on the screen panel through the LIDAR sensor;
- and
- a server which detects an installation error of the LIDAR sensor based on the uppermost end point of the LIDAR beam irradiated to each of the screen panels by comparing LIDAR beam images acquired from the plurality of screen panels through the NIR camera, generates a sensor correction value for self-correcting the installation error, and transmits the sensor correction value to the LIDAR sensor through a communication terminal equipped in the vehicle.
A method of inspecting a LIDAR sensor for correcting an error of the LIDAR sensor installed in a vehicle, the method comprising the steps of:
- a) performing communication with a communication terminal of the vehicle entering an inspection process and aligning the vehicle to a reference inspection position of the LIDAR sensor through a centering unit;
- b) capturing a LIDAR beam image irradiated from the LIDAR sensor to a screen panel through a Near Infrared (NIR) camera, wherein the screen panel is installed at a set distance and a set height with respect to the LIDAR sensor;
- c) detecting an installation error of the LIDAR sensor based on an uppermost end point of a LIDAR beam irradiated to the screen panel by comparing LIDAR beam images acquired from the plurality of screen panels;
- and
- d) generating a sensor correction value for self-correcting the installation error, and transmitting the sensor correction value to the LIDAR sensor through a communication terminal.
A system for inspecting a LIDAR sensor for correcting a LIDAR sensor error of a vehicle, the system comprising:
- a centering unit which aligns a vehicle entering an inspection process to match a reference inspection position of a LIDAR sensor;
- a Near Infrared (NIR) camera configured in an integrated module with a screen panel installed at a set distance and a set height within an operation range around the LIDAR sensor and captures a LIDAR beam image irradiated to the screen panel;
- and
- a server which collects the LIDAR beam image captured by the NIR camera, inspects an installation error by comparing an uppermost end point of the LIDAR beam captured by each of the screen panels in front of and at a side of the LIDAR sensor and the uppermost end point of a normal LIDAR beam, generates a sensor correction value for self-correcting the installation error, and transmits the sensor correction value to the LIDAR sensor through a communication terminal equipped in the vehicle.
