An accuracy of detection of a road surface or the like is improved even in a state where a peak power of reflected light is low. A sensor control device is configured to be mounted in a vehicle capable of acquiring a current location and configured to control a LiDAR-having a light source which emits light to a predetermined region and a light receiving element which receives reflected light of the emitted light, and the sensor control device includes an adjustment unit which acquires map information and adjusts a light receiving level of a light receiving signal of the light receiving element. The adjustment unit determines, based on the map information, a region for which the light receiving level with respect to the light receiving signal is to be adjusted.

Sensor control device

The present invention identifies a danger spot effectively. In a navigation devicea danger spot identification unitidentifies a jump-out danger spot on the basis of past information which is acquired by a past information acquisition unitand indicates a situation of a jump-out accident in the past, and surrounding information which is acquired by a surrounding information acquisition unitand indicates a surrounding situation of a vehicle. Here, the past information includes surrounding facility identification information (information related to an identification planimetric feature) used for identifying a jump-out danger spot and information related to a jump-out object. As a result, the danger spot identification unitcan identify a danger spot of a jump-out which can occur due to a planimetric feature (a facility) in a jump-out accident. Therefore, the navigation devicecan identify a jump-out danger spot effectively.

Dangerous place identification device, map data, dangerous place identification method, and program

A server device efficiently acquires information of a surrounding area of a movable body for updating map information while suppressing communication load. Condition information indicating a condition of autonomous driving is received from a first movable body capable of autonomous driving based on a state of a surrounding area of the first movable body and a map, and a request for state information is transmitted to a second movable body capable of transmitting the state information indicating a state of a place where the first movable body has moved, and when the received condition information indicates that the autonomous driving has been possible, transmission of the request is prevented.

Provided is a 3D data generating device and the like capable of generating 3D data having a small data size. When generating three-dimensional (3D) data in which a predetermined space is expressed by a plurality of cuboids obtained by partitioning the predetermined space, a position in the height direction for partitioning the predetermined space is decided on the basis of heights corresponding to predetermined objects, and the predetermined space is partitioned at the decided position in the height direction.

In a content delivery method in a P2P network, a node managing a content causes a downstream node to manage a volume of a divided content; this volume is according to a situation of the downstream node (for example, a line speed to which a node is connected). A node managing a content holds, as management information, partial information of the divided content managed by its own node, and location information indicative of a location at which a content itself is presented. Next, when a content transfer request is sent to a node managing a content, the node accesses a content holding node in accordance with the held location information, downloads a volume of a divided content indicated by the partial information, and uploads the volume of the divided content to a node that sends the content transfer request.

Content delivery apparatus, content delivery method, and content delivery program

A network configuration management method has a step of sequentially propagating a network ticket that a network configuration monitoring node has issued to each of a predetermined number of nodes (predetermined number of nodes&#x3c;number of all nodes) from the node to the node so as to cover all nodes of a P2P network, a step in which each of the nodes having received the network ticket plays a role to investigate the node adjacent to its own node, creates information on a network configuration around its own node, and transmits the information on the network configuration created by each of the nodes to the network configuration monitoring node. Furthermore, in the network configuration management method, the network configuration monitoring node grasps the configuration of the entire P2P network from the collected information on the network configuration.

In a content delivery method in a P2P network, a content publishing node divides a publish content according to a situation of each downstream node adjacent thereto, and causes each downstream node to hold a divided content, and a content downloading node simultaneously downloads in parallel the divided contents from the plurality of downstream nodes. When a plurality of pieces of tag information on a plurality of divided contents of a same content is received form a downstream node, the plurality of pieces of tag information are merged to be distributed in upstream nodes.
