Methods and systems for calibrating vehicle vision systems
View Patent ↗A method for calibrating a vision system of a vehicle includes the steps of projecting a pattern in proximity to the vehicle and calibrating the vision system using an image of the pattern generated by the vision system.
1. A method for calibrating a vision system of a vehicle, the method comprising the steps of:
projecting, from a laser, a pattern in an infrared spectrum on a road in proximity to the vehicle; and
calibrating the vision system using an image of the pattern generated by the vision system.
2. The method of claim 1 , further comprising the step of:
initiating a calibration mode;
wherein the steps of projecting and calibrating the vision system are conditioned upon the initiation of the calibration mode.
3. The method of claim 1 , wherein the step of projecting comprises the step of:
projecting, from the laser, a grid pattern in an infrared spectrum on a road in proximity to the vehicle.
4. The method of claim 1 , wherein the step of calibrating the vision system comprises the step of:
comparing the image to a known reference image.
5. The method of claim 1 , wherein the vision system comprises a first camera and a second camera, and the step of calibrating the vision system comprises the steps of:
processing a first image of the pattern, the first image generated by the first camera;
processing a second image of the pattern, the second image generated by the second camera; and
comparing the first and second images.
6. A non-transitory processor-readable storage medium having processor-readable code embodied thereon for programming at least one processor to perform a method for calibrating a vision system of a vehicle, the method comprising:
projecting a pattern from a laser in an infrared spectrum on a road in proximity to the vehicle; and
calibrating the vision system using an image of the pattern generated by the vision system.
7. The method according to claim 6 , wherein the program is further configured to at least facilitate:
initiating a calibration mode; and
projecting the pattern and calibrating the vision system conditioned upon the initiation of the calibration mode.
8. The method according to claim 6 , wherein the pattern comprises a grid pattern.
9. The method according to claim 6 , wherein the program is further configured to at least facilitate calibrating the vision system by comparing the image to a known reference image.
10. The method according to claim 6 , wherein:
wherein the vision system comprises a first camera and a second camera, and further comprising:
processing a first image of the pattern, the first image generated by the first camera;
processing a second image of the pattern, the second image generated by the second camera; and
comparing the first and second images.
11. A system for calibrating a vision system of a vehicle, the system comprising:
a laser configured to project a pattern in an infrared spectrum on a road in proximity to the vehicle; and
a processor configured to at least facilitate calibrating the vision system using an image of the pattern generated by the vision system.
12. The system of claim 11 , wherein the pattern comprises a grid pattern.
13. The system of claim 11 , wherein the processor is further configured to at least facilitate calibrating the vision system by comparing the image to a known reference image.
14. The system of claim 11 , wherein:
the vision system comprises a first camera and a second camera; and
the processor is further configured to at least facilitate calibrating the vision system by:
processing a first image of the pattern, the first image generated by the first camera;
processing a second image of the pattern, the second image generated by the second camera; and
comparing the first and second images.
