CPC G06T 7/80 (2017.01) [G06T 7/20 (2013.01); G06V 20/588 (2022.01); G06T 2207/30256 (2013.01)] | 20 Claims |
1. A method for detecting a calibration requirement for at least one image sensor, comprising:
detecting a ground pattern in a generated image associated with a surrounding view of a vehicle;
extracting at least one key point associated with the detected ground pattern, from the generated image;
determining a relative motion parameter associated with the extracted at least one key point based on tracking of the extracted at least one key point over a period of time, further comprising:
detecting a first location of the at least one key point at a first-time instance in the period of time;
detecting a second location of the at least one key point at a second time instance in the period of time;
generating a line extending between the first location and the second location; and
determining the relative motion parameter associated with the extracted at least one key point based on an orientation of the generated line with respect to the vehicle's body;
detecting calibration requirement for the image sensor based on the determined relative motion parameter; and
generating an output signal based on the detected calibration requirement.
