1. A method comprising:
obtaining first camera images of a parking location before a vehicle is parked at the parking location;
obtaining second camera images of the parking location after the vehicle is parked at the parking location;
detecting, via a processor, a fluid leak for the vehicle based on a comparison of the first camera images and the second camera images, including by utilizing computer vision techniques to compare an exposure and white balance between the first camera images and the second camera images along with a library of color data pertaining to fluid information for the vehicle;
obtaining sensor data via one or more sensors of the vehicle; and
scheduling an assessment, via the processor as to whether to perform an intelligent health scheduler using vision technology in order to ascertain whether there is a fluid leak for the vehicle, based on whether a plurality of health scheduler conditions are satisfied, including: (i) location data of the sensor data indicates that a parking spot is nearby; (ii) a current time of day is consistent with vehicle parking; (iii) a road inclination is less than a predetermined threshold; (iv) a light condition level exceeds a predetermined threshold; (v) weather conditions are sufficient for capturing images of any fluid leak; (vi) one or more camera conditions are satisfied for proper camera operation; and (vii) the vehicle is stationary at the parking spot for at least a predetermined amount of time;
wherein the steps of obtaining the first camera images, obtaining the second camera images, and detecting the fluid leak based on the comparison of the first camera images and the second camera images are performed based on whether each of the plurality of health scheduler conditions are satisfied.
