摘要： An advanced map DB 43 stored on a server device 4 includes pulse type information that is configuration information for detecting a landmark using a LIDAR 2. By sending request information D1 including own vehicle position information, the vehicle mounted device 1 receives response information D2 including pulse type information corresponding to a landmark around the own vehicle position and controls the LIDAR 2 on the basis of the received pulse type information.

摘要： The light control device emits a light from the emission unit, and receives the light reflected by an object by the light receiving unit. The acquisition unit acquires inclination information related to an inclination of the movable body, and the controller controls an emission direction of the light emitted by the emission unit based on the inclination information.

摘要： An acquisition unit acquires a light path length rij corresponding to an emission direction of emitted light, which is surrounding information of a moving body obtained by using a laser radar mounted on the moving body, a traffic mirror information including a center position N of a traffic mirror on a map, and position information of the moving body on the map. Then, on the basis of the acquired traffic mirror information and the acquired position information of the moving body on the map, an extraction unit extracts a light path length acquired via the traffic mirror from the acquired light path length rij, and then calculates an object reflection position corresponding to the extracted light path length. This makes it possible to obtain surrounding information in a blind spot for a driver while increasing robustness with respect to the surrounding information, and thus advanced driving assistance can be implemented.

摘要： The light control device is installed in a movable body, and comprises a light transmission/reception unit including an emission unit and a light receiving unit. The emission unit emits a light, and the light receiving unit receives the light reflected by an object around the movable body. The control unit controls the emission unit to continuously shift the light emitted by the emission unit in a first direction and a second direction crossing the first direction such that a transition locus of the light emitted by the emission unit becomes helical.

摘要： The information processing device includes a plurality of light transmission/reception units and an information processing unit. Each of the light transmission/reception unit includes an emission unit which emits a light, a scanning unit which scans the light emitted by the emission unit, and a light receiving unit which receives the light reflected by an object. The information processing unit obtains at least one of a distance to the object and an angle of the object based on light receiving results of the light receiving units. Each of the scanning units is arranged at a position where there is a direction in which the light scanned by the scanning unit is blocked by a vehicle itself, and scans the light omnidirectionally in a horizontal direction in a manner shared by the scanning units.

摘要： A LIDAR unit includes: an LD driver, a laser diode, and a scanner corresponding to an emission unit; a photo detector, a current/voltage conversion circuit, a A/D converter and an valuable segmenter that correspond to a light receiving unit; a landmark position prediction unit and landmark map acquisition unit that acquire position information indicating the position of a landmark on a map; and a synchronization controller that generates a valuable pulse trigger signal and a segment extraction signal. Based on a predicted current vehicle position value and the position of the landmark on the map, the landmark position prediction unit determines a predicted angular range of the landmark. The synchronization controller generates the valuable pulse trigger signal and the segment extraction signal such that the scan density of the light pulse is higher in the predicted angular range than the scan density of the light pulse in the other range.
