SYSTEM AND METHOD OF CALIBRATING AN OPTICAL SENSOR MOUNTED ON BOARD OF A VEHICLE
One embodiment provides a method for calibrating an optical sensor mounted on board of a vehicle, including the steps of: positioning the vehicle in a test station; arranging a projection surface for images or videos opposite the test station; identifying the type of optical sensor; selecting in a memory an image or video associated with the type of optical sensor; projecting the image or video selected onto the projection surface; and adjusting the position of the optical axis of the optical sensor starting from the projected image or video. Other aspects are described and claimed.
1 . A calibration system that calibrates an optical sensor mounted on board of a vehicle, comprising:
a test station consisting of a horizontal or inclined support zone for supporting the vehicle;
a projection surface for images or videos, said projection surface being located in front of said test station;
at least one memory containing a plurality of images and/or videos archived by type of optical sensor;
a calibration unit for calibrating the optical sensor configured to adjust the position of the optical axis of said optical sensor; and
a control unit which, in response to a signal representing the type of said optical sensor, is configured to:
search in said memory for at least one image or video archived in association with the type of said optical sensor;
command the projection onto said projection surface of the image or video found in said memory or a processed version of said image or said video;
interface with said calibration unit; and
adapt or deform the image or video found in said memory to the size of the projection surface.
2 . The calibration system according to claim 1 , further comprising a screen or monitor located in front of said test station, said projection surface being the display of said monitor.
3 . The calibration system according to claim 2 , further comprising a television set, said monitor being the monitor of said television set.
4 . The calibration system according to claim 2 , further comprising a multimedia interactive board, said monitor being the monitor of the multimedia interactive board.
5 . The calibration system according to claim 2 , further comprising a computer, said monitor being the monitor of the computer.
6 . The calibration system according to claim 1 , wherein said projection surface is obtained from a sheet made of PVC.
7 . The calibration system according to claim 1 , further comprising a projector or a luminous board, said control unit being configured to command the projector or luminous board to project the image or video found in said memory onto said projection surface.
8 . The calibration system according to claim 1 wherein, in response to the signal representing the type of said optical sensor, said control unit is configured to project a set of parameters or initial calibration conditions onto said projection surface.
9 . The calibration system according to claim 8 , further comprising a projector or a luminous board, said control unit being configured to command the projector or luminous board to project the image or video found in said memory onto said projection surface.
10 . A method of calibrating an optical sensor mounted on board of a vehicle, comprising the steps of:
positioning the vehicle in a test station consisting of a horizontal or inclined support zone for supporting the vehicle;
arranging a projection surface for images or videos in front of said test station;
identifying the type of said optical sensor;
selecting in a memory an image or video associated with the type of said optical sensor;
adapting or deforming the image or video selected in said memory ( 6 ) to the size of the projection surface;
projecting the image or video selected or the adapted or deformed version thereof onto said projection surface; and
adjusting the position of the optical axis of said optical sensor starting from said projected image or video.
