  • Publication number: 20210197811
    Abstract: A course prediction device (1) includes a blind spot calculation unit (11) and a prediction unit (12). The blind spot calculation unit (11) acquires a sensing result sequentially from a sensor which is arranged in a mobile object and which detects whether an object exists, and calculates, based on sensor information, a blind spot area expressing such an area that an object existing therein cannot be detected by the sensor. The blind spot calculation unit (11) also detects an object entering the blind spot area based on the sensor information. The prediction unit (12) predicts a course in the blind spot area of the detected object based on the sensing result.

  • Publication number: 20210141054
    Abstract: A failure detection apparatus (10) acquires, as target data, sensor data output in a past reference period by a sensor (31), such as a millimeter wave radar or LiDAR (Light Detection And Ranging), mounted on a moving body (100). The failure detection apparatus (10) determines whether detected data indicating a characteristic of a detected object indicated by normal data, which is sensor data output when the sensor (31) is normal, is included in the acquired detected data in the past reference period. In this way, the failure detection apparatus (10) determines whether a failure has occurred in the sensor (31).

  • Publication number: 20210065553
    Abstract: An information processing device is mounted on a movable body. A calculation unit acquires sensor data in which detection points are indicated, the detection points being acquired by scanning a periphery of a sensor by the sensor, the sensor being located at the periphery of the movable body, analyzes the acquired sensor data, and calculates a distribution range of the detection points. Based on the distribution range of the detection points calculated by the calculation unit, a removal unit extracts a detection point for the movable body from among the detection points indicated in the sensor data, and removes the extracted detection point for the movable body from the sensor data.

  • Publication number: 20200384990
    Abstract: A driving monitoring device (100) decides an applicable collision pattern that applies to a collision pattern of a case where a vehicle (200) collides with a mobile object, based on a velocity vector of the vehicle, a velocity vector of the mobile object, and so on. Subsequently, the driving monitoring device calculates a time until collision, which is a time taken until the vehicle collides with the mobile object, in the applicable collision pattern. Then, the driving monitoring device calculates a danger level of an accident in which the vehicle collides with the mobile object, based on the applicable collision pattern and the time until collision.

  • Patent number: 10796569
    Abstract: A direction identification unit (21) identifies a traveling direction in which a surrounding vehicle travels in a partial region of a region indicated by image information (42) obtained by photographing using a camera (31). A feature amount acquisition unit (22) acquires a reference feature amount (41) being a feature amount computed from a reference image corresponding to the identified traveling direction. A vehicle determination unit (23) computes an image feature amount being a feature amount of the image information of the partial region and compares the computed image feature amount with the acquired reference feature amount (41), thereby determining whether the surrounding vehicle is present in the partial region.

  • Patent number: 10410072
    Abstract: A driving support apparatus (10) converts at least one of a first map (43) and a second map (53) so that the first map (43) and the second map (53) become three-dimensional maps in a same coordinate system. The first map (43) is a three-dimensional map indicating three-dimensional positions of objects around a vehicle (100). The second map (53) is a three-dimensional map indicating three-dimensional positions of objects around an external apparatus (200) that is one of a roadside apparatus (201) and a different vehicle (202) from the vehicle (100). Then, the driving support apparatus (10) synthesizes the first map (43) and the second map (53) after the conversion, thereby generating a composite map (44).

  • Publication number: 20190043235
    Abstract: An image generation unit generates a support image indicating a reference position of an object. A visibility determination unit determines whether or not a reference range based on the reference position can be visually recognized from a moving body. If it has been determined that the reference range can be visually recognized, a display control unit causes the support image to be displayed, such that the support image without alteration is superimposed on a landscape around the moving body. If it has been determined that the reference range cannot be visually recognized, the display control unit alters the support image, and then causes the altered support image to be displayed, such that the altered support image is superimposed on the landscape around the moving body.
