Information processing apparatus, information processing method, and program

An information processing method, comprising:

• acquiring first data including at least one of position information of an object present in a vehicle surrounding environment or road surface tilt information and a time stamp indicating date and time of acquisition of the information, the position information and the road surface tilt information being generated by using sensing data of one or more sensors mounted on a vehicle;
• acquiring second data including at least one of position information of the object present in the vehicle surrounding environment or road surface tilt information and the time stamp indicating the date and time of acquisition of the information, the position information and the road surface tilt information being generated by using sensing data of one or more sensors other than those of the vehicle;
• acquiring, from an information processing device installed along a road surface and that acquires position information of a marker in advance, the position information of the marker as the second data;
• comparing the first data with the second data on a basis of the time stamp included in each of the first data and the second data;
• detecting an abnormality related to a sensor mounted on the vehicle on a basis of a result of the comparison;
• starting the acquiring of the first data based on the vehicle being positioned within a reference data range in which the vehicle can acquire the position information of the marker;
• determining a completion of the acquiring of the first data based on the first data being acquired for a predetermined period of time;
• and
• starting the acquiring of the second data from the information processing device installed along the road surface based on the determined completion.

A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute an information processing method, the method comprising:

• acquiring first data including at least one of position information of an object present in a vehicle surrounding environment or road surface tilt information and a time stamp indicating date and time of acquisition of the information, the position information and the road surface tilt information being generated by using sensing data of one or more sensors mounted on a vehicle;
• acquiring second data including at least one of position information of the object present in the vehicle surrounding environment or road surface tilt information and the time stamp indicating the date and time of acquisition of the information, the position information and the road surface tilt information being generated by using sensing data of one or more sensors other than those of the vehicle;
• acquiring, from an information processing device installed along a road surface and that acquires position information of a marker in advance, the position information of the marker as the second data;
• comparing the first data with the second data on a basis of the time stamp included in each of the first data and the second data;
• detecting an abnormality related to a sensor mounted on the vehicle on a basis of a result of the comparison;
• starting the acquiring of the first data based on the vehicle being positioned within a reference data range in which the vehicle can acquire the position information of the marker;
• determining a completion of the acquiring of the first data based on the first data being acquired for a predetermined period of time;
• and
• starting the acquiring of the second data from the information processing device installed along the road surface based on the determined completion.
