Information processing method, information processing device, non-transitory computer-readable recording medium recording information processing program, and information processing system

An information processing device comprising:

• a video data acquisition unit that acquires video data from a camera that captures surroundings of a vehicle;
• a sensor data acquisition unit that acquires sensor data including at least one of acceleration, speed, and angular velocity of the vehicle;
• a time information giving unit that gives time information indicating time of acquisition to each of the video data and the sensor data;
• an identification unit that identifies a content of an event occurred in the vehicle based on the sensor data;
• a determination unit that determines whether or not the identified event s a predetermined event;
• a specification unit that specifies video data to which time information same as time information given to the sensor data used for identification is given, when the identified event is determined to be the predetermined event;
• and
• a transmission unit that transmits the specified video data.

A non-transitory computer-readable recording medium recording an information processing program causing a computer to function as:

• a video data acquisition unit that acquires video data from a camera that captures surroundings of a vehicle;
• a sensor data acquisition unit that acquires sensor data including at least one of acceleration, speed, and angular velocity of the vehicle;
• a time information giving unit that gives time information indicating time of acquisition to each of the video data and the sensor data;
• an identification unit that identifies a content of an event occurred in the vehicle based on the sensor data;
• a determination unit that determines whether or not the identified event is a predetermined event;
• a specification unit that specifies video data to which time information same as time information given to the sensor data used for identification is given, when the identified event is determined to be the predetermined event;
• and
• a transmission unit that transmits the specified video data.

An information processing system including a terminal device mounted on a vehicle, a data analysis server communicably connected with the terminal device, and a video accumulation server communicably connected with the terminal device,

• wherein the terminal device includes
• a video data acquisition unit that acquires video data from a camera that captures surroundings of a vehicle,
