Classification: CPC G | IPC G

Claim 16:
17. A non-transitory computer-readable medium having stored thereon computer-executable instructions which when executed by at least one processor, cause the at least one processor to conduct operations for detecting a calibration requirement for at least one image sensor, the operations comprising:
detecting a ground pattern in a generated image associated with a surrounding 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:
detect a first location of the at least one key point at a first-time instance in the period of time;
detect a second location of the at least one key point at a second time instance in the period of time;
generate a line extending between the first location and the second location; and
determine 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 at least one image sensor based on determined relative motion parameter; and
generating an output signal based on the detected calibration requirement.
