Abstract: A position detection unit detects positions of right and left shoulders of a driver, and positions of at least two body parts of the driver from a driver image obtained by capturing an image of the driver. A shoulder width calculation unit calculate a width of shoulders of the driver based on the detected positions of the right and left shoulders. A threshold determination unit determines at least one determination threshold based on the calculated width of shoulders. A determination unit determines a driving state of the driver by using the positions of the at least two detected body parts detected by the position detection unit and the at least one determination threshold determined by the threshold determination unit.

Abstract: A movement vector calculation unit calculates movement vectors between frames of a video image of an area ahead of a vehicle. The video image is input as a moving image. An area inference unit infers an area indicating a movable object included in the video image of the area ahead of the vehicle. A vector excluding unit excludes, from among the calculated movement vectors, movement vectors in an area inferred as being the area indicating the movable object. A behavior inference unit infers behavior of the vehicle based on the movement vectors from which those in the area inferred as being the area indicating the movable object have been excluded.

Abstract: An object recognition system 80 includes: a recognition device 30 that recognizes an object in an image; and a server 40 that generates a learning model. The recognition device 30 includes: a first object recognition unit 310 that determines a type of the object in the image using the learning model; and an image transmission unit 320 that transmits a type-indeterminable image, which is an image in which the type has not been determined, to the server 40 when an object included in the type-indeterminable image is an object detected as a three-dimensional object. The server 40 includes: a learning device 410 that generates the learning model based on training data in which a teacher label is assigned to the type-indeterminable image; and a learning model transmission unit 420 that transmits the generated learning model to the recognition device 30. The first object recognition unit 310 determines the type of the object in the image using the transmitted learning model.

Abstract: A dangerous scene prediction device 80 for predicting a dangerous scene occurring during driving of a vehicle includes a learning model selection/synthesis unit 81 and a dangerous scene prediction unit 82. The learning model selection/synthesis unit 81 selects, from two or more learning models, a learning model used for predicting the dangerous scene, depending on a scene determined based on information obtained during the driving of the vehicle. The dangerous scene prediction unit 82 predicts the dangerous scene occurring during the driving of the vehicle, using the selected learning model.

Abstract: An object recognition device 80 includes a scene determination unit 81, a learning-model selection unit 82, and an object recognition unit 83. The scene determination unit 81 determines, based on information obtained during driving of a vehicle, a scene of the vehicle. The learning-model selection unit 82 selects, in accordance with the determined scene, a learning model to be used for object recognition from two or more learning models. The object recognition unit 83 recognizes, using the selected learning model, an object in an image to be photographed during driving of the vehicle.

Abstract: An image generation apparatus (20) includes an acquisition unit (210) and a data processing unit (220). The acquisition unit (210) repeatedly acquires analysis data from at least one sending apparatus (10). The analysis data include at least type data and relative position data. The data processing unit (220) generates, each time analysis data are acquired, a reconfigured image by using the analysis data, and causes a display (230) to display the reconfigured image. Further, the data processing unit (220) requests the sending apparatus (10) for a captured image, when a criterion is satisfied.

Abstract: Data transmission means divides data into one or more transmission packets in units of a predetermined size in conformity with a predetermined protocol, transmits the transmission packets to a reception apparatus, and receives an acknowledgement packet returned from the reception apparatus. Data size acquisition means acquires a data size of transmission data. Acknowledgement reception time acquisition means acquires a reception time of an acknowledgement packet. An available bandwidth calculation means calculates the available bandwidth in a network using the reception time of the acknowledgement packet when a sum of the data sizes of the transmission data in the predetermined time is double or more the predetermined size.

Abstract: An object recognition unit recognizes an object included in an image captured by a camera mounted on a vehicle. A first distance estimation unit estimates a distance between the vehicle and the recognized object based on the image. A second distance estimation unit estimates the distance between the vehicle and the recognized object based on the image by using an estimation method different from that of the first distance estimation unit. A combining unit combines a result of estimating the distance obtained by the first distance estimation unit and a result of estimating the distance obtained by the second distance estimation unit based on at least one of an amount of change in the distance estimated by the second distance estimation unit, a steering wheel angle of the vehicle, and information about an acceleration in an up-down direction, and outputs a result of the combination as a ranging result.
