An object detection device is configured to be mounted to an own vehicle to detect an object present around the own vehicle. The object detection device includes a coordinate acquisition section and an object recognition section. The coordinate acquisition section acquires position coordinates of a detection point corresponding to the object on the basis of a plurality of images captured at different positions along with movement of the own vehicle by one imaging section mounted to the own vehicle. The object recognition section recognizes the object without using position coordinates of a movement point that is a detection point corresponding to a moving object but using position coordinates of a stop point that is a detection point different from the movement point.

Object detection device, object detection method, and storage medium

A control device to be applied to a vehicle equipped with an imaging device and a safety device is configured to, based on moving-object detection information detected from images captured by the imaging device, actuate the safety device for a moving object. In the control device, a control unit is configured to, in response to any of certain information that it is certain that the object is a moving object and uncertain information indicating that it is not certain whether the object is a moving object being acquired as moving-object detection information, actuate the safety device based on a position of the object subjected to detection with the certain information or the uncertain information. An actuation region setting unit is configured to, when the moving-object detection information is the uncertain information, narrow an actuation region as compared to when the moving-object detection information is the certain information.

Control device for controlling safety device in vehicle

A moving object determination device applied to a vehicle, the device includes at least a predicted time calculation unit, a time difference calculation unit, and a moving/stationary determination unit. The predicted time calculation unit calculates a predicted time from when an obstacle starts to be detected by the first sensor to when the obstacle will no longer be detected by the second sensor based on a traveling speed of the obstacle and a length of the obstacle. The time difference calculation unit calculates a real time from when the obstacle has been detected by the first sensor to when the obstacle has no longer been detected by the second sensor, and calculates a time difference between the real time and the predicted time. The moving/stationary determination unit determines that the obstacle is a stationary object in response to the time difference being equal to or greater than a predetermined value.

Obstacle recognition device

An obstacle identification apparatus acquires an image that is captured by a camera that is mounted to a vehicle. The obstacle identification apparatus calculates a first gradient that is a gradient in a first direction of a luminance value of pixels in the image and a second gradient that is a gradient of the luminance value in a second direction orthogonal to the first direction of the first gradient. Based on the first gradient and the second gradient, the obstacle identification apparatus estimates a shadow boundary that is a boundary between an own-vehicle shadow that is a shadow of the own vehicle and an object outside the vehicle. Based on the estimated shadow boundary, the obstacle identification apparatus estimates the own-vehicle shadow.
