Claim 21:
22. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to:
collect a two-dimensional image of a vehicle occupant in a vehicle;
input the collected two-dimensional image to a machine learning program trained to output one or more reference points of the vehicle occupant, each reference point being a landmark of the vehicle occupant;
output, from the machine learning program, one or more reference points of the vehicle occupant in the two-dimensional image;
determine a location of the vehicle occupant in an interior of the vehicle based on the one or more reference points;
actuate a vehicle component based on the determined location;
for each of the one or more reference points, determine a similarity measure between the reference point and a three-dimensional reference point, the similarity measure based on a distance between the reference point and the three-dimensional reference point; and
reactivate a three-dimensional image sensor when a similarity measure between a new three-dimensional reference point and one of the one or more reference points of the vehicle occupant in the image is below a threshold.
