  • Publication number: 20220198809
    Abstract: A vehicle speed acquiring unit acquires a vehicle speed. A moving range calculating unit calculates, based on the vehicle speed, a pre-stop moving range within which the vehicle may cover before coming to a stop. A sensor information acquiring unit acquires object detection information indicating a detected object, detected by a sensor, in the surroundings of the vehicle. An image superposing unit superposes the pre-stop moving range and the position of the detected object included in the object detection information on top of each other on a screen. In addition, the image superposing unit generates a superposed image that displays the position of a detected object estimated, based on position information of the detected object included in the object detection information, to have a possibility of overlapping the pre-stop moving range, more saliently than the positions of other detected objects. An image presenting unit presents the generated superposed image.

  • Patent number: 11301692
    Abstract: An information processing apparatus detects an object queue from a video frame and generates tracking information indicating a position of each tracking target object, where each object included in the object queue is the tracking target object. The information processing apparatus generates queue behavior information related to a behavior of the object queue at a first time point using the tracking information at the first time point. The information processing apparatus computes an estimated position of each tracking target object at a second time point later than the first time point based on the tracking information and the queue behavior information at the first time point. The information processing apparatus updates the tracking information based on the position of each object detected from the video frame at the second time point and the estimated position of each tracking target object at the second time point.
