An object detection device comprising a first detecting part detecting types and positions of objects including a road mirror in an image and a presence of a movable object reflected in the road mirror based on image data of a low resolution image and a second detecting part detecting a type of the movable object in the road mirror and a position of the movable object in the road mirror based on high resolution partial image data obtained by extracting the part of the road mirror from the image if there is a movable object reflected in the road mirror.

Object detection device, object detection method, and non-transitory computer readable medium comprising computer program for object detection-use

A proceedable direction detection apparatus includes a processor. The processor inputs an image acquired from an image capturing unit mounted on a vehicle into a classifier that is pre-trained to output a proceedable certainty degree indicating a proceedable probability of each relative bearing with respect to a predetermined direction relative to a vehicle based on a display status of a traffic signal in the image. The processor calculates, using the classifier, the proceedable certainty degree of each relative bearing based on the display status of the traffic signal in the image. The processor determines the direction in which the vehicle can proceed based on a proceedable certainty degree of each relative bearing.

Proceedable direction detection apparatus and proceedable direction detection method

An object detection device includes a processor configured to calculate, for each of a plurality of regions in a detection range of the sensor represented in the newest sensor signal among a plurality of sensor signals in time-series acquired by a sensor, a confidence indicating a degree of certainty that an object to be detected is represented in the region; track a first object which has been detected, to detect, in the newest sensor signal, a passed region through which the first object has passed; control, for each of the plurality of regions in the newest sensor signal, a confidence threshold according to whether or not the region is included in the passed region, and detect a second object in a region, among the plurality of regions, with respect to which the confidence for the second object is equal to or higher than the confidence threshold.

Object detection device and object detection method

An image selection device includes a processor configured to: input, for each of a series of images acquired from a camera mounted on a vehicle, the image to a classifier to detect a region including an object represented on the image; track the detected object over the series of images; and select, when a period in which the detected object can be tracked is equal to or more than a predetermined period, and a size of a region including the detected object in any one image during the period in which the object can be tracked is equal to or more than a predetermined size threshold value, among the series of images, an image immediately before the period in which the object can be tracked, or an image in which the tracked object is not represented during the period in which the object can be tracked.

Image selection device and image selection method

A training image selection system' comprises: an imaging devicecapturing an outside of a host vehicle to generate images, a storage devicestoring the images generated by the imaging device, a detecting partconfigured to detect operation of signaling lights of the host vehicle, and an image selecting partconfigured to select training images from the images generated by the imaging device. If the detecting part detects operation of signaling lights, the image selecting part is configured to select images generated at timings within a predetermined range from when operation of signaling lights is detected, as training images.

Training image selection system

An object detection devicecomprises a position region detecting partusing a first neural network to detect a position region of an object in the image, a large attribute identification partconfigured using a second neural network to identify a large attribute of the object, a small attribute identification partusing a third neural network to identify a small attribute of the object, and an object judging partjudging a result of detection of the object. The object judging part is configured to judge that a result of identification of the small attribute is the result of detection if a confidence of the result of identification of the small attribute is equal to or more than a threshold value, and judge the result of detection based on a result of identification of the large attribute if the confidence is less than the threshold value.

Object detection device, vehicle control system, object detection method, and non-transitory computer readable medium

An object recognition apparatus is provided with: a first output device configured to output a provisional position of a first object and a tracking priority by using a neural network; and a second output device configured to receive entries of the first image data, the provisional position and the tracking priority, and configured (i) to perform a time-series tracking process and output a position and a speed, for the first object in which the tracking priority satisfies a predetermined condition, and (ii) to output a position without performing the time-series tracking process, for the first object in which the tracking priority does not satisfy the predetermined condition. The neural network is a learned neural network that has learned by using teacher data, wherein the teacher data includes second image data, and correct answer data.
