This object detection device includes: a radar erroneous detection determination unit which sets, as true, a radar erroneous detection suspicion flag for radar detected object information determined to be suspected as erroneous detection; a fusion processing unit which outputs fusion object information on the basis of second sensor detected object information and the radar detected object information acquired from the radar erroneous detection determination unit; and a radar erroneous detection removal unit which removes fusion object information determined to be suspected as erroneous detection. When a fusion object is determined to be an object detected by only a radar, the fusion processing unit sets a single-sensor detection flag for the fusion object information, as true. The radar erroneous detection removal unit removes the fusion object information for which the radar erroneous detection suspicion flag is true and the single-sensor detection flag is true.

Object detection device, object detection method, and computer-readable storage medium

An object detection apparatus includes a distance calculation unit (), a position coordinate calculation unit (), and a noise removal unit (). The distance calculation unit () regards as a target reception signal, each of a plurality of reception signals received by each of a plurality of receivers, detects as a target peak, each of at least one of peaks corresponding to the target reception signals, and calculates as a calculated distance, a distance corresponding to the target peak. The position coordinate calculation unit () calculates a detection point indicating position coordinates indicating a position at which an object is estimated to be present, based on each combination of the calculated distance corresponding to each of the plurality of reception signals and each position of the plurality of receivers, and regards as a detection result point group, a set that consists of the calculated detection points. The noise removal unit () removes from the detection result point group, a detection point corresponding to noise, based on the position coordinates of each detection point included in the detection result point group.

Object detection apparatus, object detection method, and non-transitory computer readable-medium

Conventionally, a method in which pieces of point group information for use in position matching between a white line position detected by an object detection sensor and a white line position on a map are extracted from the white line positions according to a travel environment, has not been taken into account. In the present disclosure, a point group extraction condition is changed according to change in the travel environment so that: a process of position matching that exhibits robustness with respect to change in the travel environment can be realized; and an own position and a white line position existing at a long distance from an own vehicle can be detected with high accuracy.

Own position inferring device

A control device includes: an object detector to output a signal for causing a transmitter to transmit an object detection ultrasonic wave, obtain an output signal from a receiver, and detect an object; an abnormality detector to perform, as an abnormality detection process, outputting a signal for causing the transmitter to transmit an abnormality detection ultrasonic wave whose transmission time is longer than that of the object detection ultrasonic wave, obtaining, from the receiver, an output signal in a period in which the abnormality detection ultrasonic wave is to be received as a direct wave, and detecting an abnormality in the transmitter or receiver when no signal of the direct wave is included; and a determiner to obtain a speed of a vehicle including the transmitter and receiver, and when the speed is not greater than a threshold, cause the abnormality detector to start the abnormality detection process.

Control device for object detection device, object detection device, and non-transitory computer-readable storage medium

A first image-data acquisition unit () acquires a plurality of pieces of image data in which different areas in a facility in which an autonomous driving vehicle conducts autonomous traveling are shown. A priority setting unit () analyzes a status shown in each of the plurality of pieces of image data and sets a priority to each image data. A first image-data display unit () decides a display mode at a time of displaying the plurality of pieces of image data according to the priority set by the priority setting unit ().

Information processing device, information processing method, and computer readable medium

A reception unit receives, with an ultrasonic sensor, received signals including a reflected wave obtained when an acoustic signal emitted from a mobile body is reflected by an object. A disturbance judgment unit judges whether a jamming attack in which a jamming signal is transmitted from outside is being made, on the basis of the received signals. An object detection unit detects an object in surroundings of the mobile body on the basis of the received signals if it is judged that no attack is being made and does not perform object detection if it is judged that an attack is being made.
