Classification: CPC G | IPC G

Claim 0:
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.
