A stop detection device includes: an acquirer that acquires multiple captured images captured in chronological order by a camera mounted on a vehicle; an image processor that performs image processing on acquired multiple captured images; and a detector that detects vehicle speed of a vehicle at a stop position based on a result of image processing. The image processor includes a stop position identification unit that detects a marking indicating a stop position from a captured image to identify a stop position, and a vehicle speed calculation unit that calculates vehicle speed by comparing captured images in chronological order. The vehicle speed calculation unit excludes a specific region from each of multiple captured images to compare captured images.

Stop detection device and stop detection method

In an information processing device (a server device), a first acquirer acquires multiple captured images of the outside of a vehicle. A detector detects, from acquired multiple captured images, multiple images related to unsafe driving using a learned model. An image extractor extracts, from detected multiple images related to unsafe driving, an image to be a candidate for relearning data of the learned model.

Information processing device and information processing method

A driving evaluation device includes a first memory and a first processor that is coupled to the first memory. The first processor is configured to cause driving information pertaining to dangerous driving incidents collected from a vehicle to be stored in a storage unit together with types and danger ratings of the dangerous driving incidents, generate evaluation information pertaining to a driver of the vehicle based on the driving information collected from the vehicle, retrieve dangerous driving incidents pertaining to the driver based on at least one of the types or the danger ratings, and provide to a user the evaluation information that has been generated and driving information pertaining to the dangerous driving incidents that have been retrieved.

A flood sensing device includes: an acquiring section that acquires plural types of traveling state data relating to traveling of a vehicle; and a sensing section that senses flooding of a road on which the vehicle travels by using (a) a physical quantity that is estimated on the basis of (i) a vehicle behavior model, which is configured by driving force of the vehicle and traveling resistance that includes air resistance applied to the vehicle, slope resistance applied to the vehicle and rolling resistance applied to the vehicle, and which determines the physical quantity that varies due to the vehicle traveling, and (ii) the plural types of traveling state data of the present time that are acquired by the acquiring section, and (b) the physical quantity that is obtained from the traveling state data of the present time that is acquired by the acquiring section.

Flood sensing device, flood sensing system, and non-transitory computer readable medium

A flood detection device and method that acquires meteorological data; acquires traffic volume data representing vehicle traffic volume; and determines that an area, in which a vehicle traffic volume during or after rain is less than or equal to a predetermined number of vehicles, is flooded based on the meteorological data and the traffic volume data, when a probability, that the vehicle traffic volume in a normal time is less than or equal to the predetermined number of vehicles, is less than a predetermined value, the normal time being a state in which a rainfall amount is less than a predetermined value.
