  • Publication number: 20210190535
    Abstract: An information processing apparatus includes an update unit and an obtaining unit. The obtaining unit obtains a second position of a map feature point included in map information based on the map information and information obtained from a vehicle sensor. The map information includes a map feature point first position measured in an environment including a closed route along which the vehicle travels. The sensor-obtained information includes a sensor feature point measured by the sensor mounted on the vehicle while the vehicle travels along the closed route. Where a distance between an estimated vehicle first position and an estimated vehicle second position is greater than a threshold, map information updating is restrained. Where the vehicle traveling near the vehicle first position continues traveling along the closed route, the update unit updates the map information between when the vehicle leaves the vehicle first position and nears the vehicle second position.

  • Patent number: 11003939
    Abstract: There is provided with an information processing apparatus. From an image capturing apparatus which can move, a captured image of an object is obtained. The position of the image capturing apparatus is derived using the captured image and a three-dimensional map. The three-dimensional map is corrected using information indicating a reliability of: information indicating the three-dimensional position of the feature included in a predefined area in the three-dimensional map held by the holding unit; and information indicating a three-dimensional position of another feature of the object, the information obtained based on the captured image from an expanded area of the predefined area in the three-dimensional map held by the holding unit.

    Abstract: There is provided with an information processing apparatus. An acquisition unit acquires a first processing result including information for identifying the position of the mobile object and a second processing result including information for identifying the position of the mobile object. The first processing result is obtained by executing a first processing method on an image obtained by measuring at least surroundings of the mobile object by using a light receiving sensor installed on the mobile object. The second processing result is obtained by executing a second processing method different from the first processing method on an observation result obtained by observing the mobile object by using a light receiving sensor installed at a location at which it is possible to observe the mobile object.

    Abstract: There is provided with an image processing apparatus. A captured image of a target object that is captured by an image capturing apparatus is obtained. Information that indicates a deterioration degree of the captured image is obtained for a position in the captured image. A feature of the target object is extracted from the captured image based on the deterioration degree. The feature of the target object and a feature of the three-dimensional model observed when the three-dimensional model is arranged in accordance with a predetermined position and orientation are associated. A position and orientation of the target object with respect to the image capturing apparatus are derived by correcting the predetermined position and orientation based on a result of association.
