Abstract: The present invention provides a driving assistance apparatus that assists driving of a vehicle, comprising: an image capturing unit configured to capture an image of the front of the vehicle; an identification unit configured to identify a traffic light in the image obtained by the image capturing unit; a detection unit configured to detect, from the image, an installation height of the traffic light identified by the identification unit; and a determination unit configured to determine whether or not the traffic light identified by the identification unit is a target traffic light indicating whether or not the vehicle travels, based on the installation height detected by the detection unit.

Abstract: A driving assistance device comprises: a recognition unit configured to recognize a lighting color of a traffic light from an image captured by a camera that images an outside world of a vehicle; and an alarm output unit configured to output an alarm to a driver of the vehicle when the lighting color is red and there is no braking operation of the vehicle. When a plurality of traffic lights are recognized from the image by processing of the recognition unit, the alarm output unit controls the output of the alarm based on a combination of lighting colors of the plurality of traffic lights.

Abstract: An information providing device includes an external environment recognition unit that recognizes an external environmental situation of a movable body, an information providing control unit that provides a notification of recommended stopping information based on a current indication of traffic signals recognized by the external environment recognition unit, and a determination unit which determines, in the case that a first intersection and a second intersection are positioned in a travel direction of the movable body, whether or not a degree of proximity of the first intersection and the second intersection satisfies a predetermined condition. In the case it is determined by the determination unit that the predetermined condition is satisfied, the information providing control unit prevents the recommended stopping information based on a current indication of the traffic signal belonging to the second intersection from being provided.

Abstract: A drive assist device includes: a marking recognition unit configured to recognize a road marking on a driving lane and a road marking on a first adjacent lane from an image of a pavement captured from a vehicle and specify a permitted travel direction of the driving lane and a permitted travel direction of the first adjacent lane; a detection unit configured to detect a lane change performed by the vehicle; and an information management unit configured to cause a storage unit to store first information indicating the permitted travel direction of the driving lane and second information indicating the permitted travel direction of the first adjacent lane specified by the marking recognition unit, and in a case in which the detection unit detects the lane change to the first adjacent lane, update the information stored in the storage unit to change the second information as the permitted travel direction of the driving lane and the first information as the permitted travel direction of a second adjacent lane.

Abstract: An information providing device is equipped with an information providing control unit that, in the case that a provision starting condition for starting to provide recommended stopping information is satisfied by a current indication of a traffic signal and a travel state, initiates the provision of the recommended stopping information, whereas in the case that a provision termination condition for stopping to provide the recommended stopping information is satisfied, terminates the provision of the recommended stopping information. After the provision of the recommended stopping information is initiated by having satisfied the provision starting condition, in the case that the provision of the recommended stopping information is terminated by having satisfied the provision termination condition, and further thereafter, the provision starting condition is satisfied again, the information providing control unit restricts re-providing of the recommended stopping information.

Abstract: A flying object position measuring apparatus includes an optical sensor, a storage, an orientation calculator, and a position calculator. The optical sensor obtains an image of a flying object. The flying object performs flight along a ballistic trajectory. The storage stores, in advance, basic trajectory information regarding a basic trajectory of the flying object. The basic trajectory information includes position information of a start point at which the flying object starts the flight. The orientation calculator calculates an orientation of the flying object as viewed from the optical sensor on the basis of the image obtained by the optical sensor. The position calculator calculates, as a position of the flying object, an intersection of a plane of rotation with the orientation of the flying object. The plane of rotation is a plane based on a rotation of the basic trajectory around a vertical axis that travels through the start point.
