Assignee: AITRONX INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. An apparatus for detecting a calibration requirement for at least one image sensor, the apparatus comprising:
a memory configured to store computer-executable instructions; and
at least one processor configured to execute the computer-executable instructions to:
detect a ground pattern in a generated image associated with a surrounding of a vehicle;
extract at least one key point associated with the detected ground pattern, from the generated image;
determine 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, wherein the instructions to determine the relative motion parameter associated with the extracted at least one key point further comprise instructions to:
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;

detect calibration requirement for the at least one image sensor based on the determined relative motion parameter; and
generate an output signal based on the detected calibration requirement.
