摘要： A first light projector projects first slit light that spreads in the width direction of a vehicle in a direction other than a direction parallel to a contact ground surface. A second light projector projects second slit light that spreads in the width direction of the vehicle in a direction parallel to the contact ground surface. An obstacle detection unit detects an obstacle using a captured image of an area surrounding the vehicle where the first slit light and the second slit light are projected.

摘要： An object detection device, detecting an object based on an image from a stereo camera on a vehicle, includes a parallax calculator, a first road parameter estimator, a road parameter storage, a second road parameter estimator, and an object detector. The parallax calculator calculates three-dimensional information of a scene in the image. The first road parameter estimator calculates a first road parameter based on the three-dimensional information. The road parameter storage associates the first road parameter with vehicle information to store therein. The second road parameter estimator calculates, based on stored information, a second road parameter using the first road parameter under a predetermined condition for the vehicle. The object detector detects the object using the second road parameter. The predetermined condition includes that an angular difference between a road surface observed from the stereo camera and a contact surface of the vehicle at observation is within a predetermined angle.

摘要： A storage device stores capturing conditions including a viewpoint position and a shooting direction of the camera, model data including a shape of a segmented mirror, and feature point data representing a positional relationship among a viewpoint position and feature points. A camera captures the segmented mirror having a reflective surface to obtain a captured image including at least a part of the reflective surface. A marker object has feature points, and is fixed at a predetermined position with respect to the camera. A feature-point extracting unit extracts multiple feature points from a captured image in which the feature points are reflected in the reflective surface, and determines positions of the feature points within the captured image. A position measuring unit calculates a position of the segmented mirror, based on the capturing conditions, the model data, the feature point data, and the positions of the feature points within the captured image.
