1. A data collection apparatus, comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
receive sensor data from a vehicle capable of photographing a road surface, the sensor data being acquired by a sensor mounted on the vehicle;
evaluate a goodness degree of a road surface photographing environment on a basis of the sensor data and control a transmission from the vehicle of a road surface photographed image on a basis of the goodness degree of the road surface photographing environment;
receive information on a distance between the vehicle and a preceding vehicle that is running in front of the vehicle as the sensor data;
evaluate the goodness degree of the road surface photographing environment using the information on the distance between the vehicle and the preceding vehicle;
receive a digest image created from the road surface photographed image as the sensor data; and
estimate the distance between the vehicle and the preceding vehicle on a basis of a size of an image of the preceding vehicle in the digest image.
