  • Publication number: 20240175687
    Abstract: A data structure of the voxel data VD according to this example is a map data structure which is a data structure of map data to be referred to by an information processing device 1, and includes position information indicating a position of a structural object and attribution information indicating whether or not the structural object is a floating object on a water surface. If the attribute information indicates that the structural object is a floating object on a water surface, the attribute information is used by the information processing device 1 to identify the position of the structural object by using the position information as relative position information relative to a position of the water surface.

  • Publication number: 20240175984
    Abstract: In the information processing device, the point cloud data acquisition means acquires point cloud data generated by a measurement device provided on a ship. The water-surface reflection data extraction means extracts data obtained by measuring a position which is a predetermined distance away from a shore and which is within a predetermined distance from a measurement position of the measurement device, as a water-surface reflection data measured by reflection at a water surface. Then, the water-surface height calculation means calculates a water-surface height based on the water-surface reflection data.

  • Patent number: 6631153
    Abstract: The invention offers a low-noise, compact, high-efficiency light generating device and an irradiation method thereof for use in medical applications. A fundamental harmonic laser head 106 is composed of a quasi-continuous wave oscillation mode laser diode (QCW-LD) 101, a laser crystal 103, a rear mirror 104 and an output mirror 105. The QCW-LD 101 is driven by an LD power source 102 capable of modulating the pulse waveform in time. A beam adjusting portion 108 comprises a wave plate, a polarizer, a lens and an isolator. A wavelength converting portion 112 is an optical parametric oscillator (OPO) comprising a non-linear optical crystal 109, an OPO input mirror and an OPO output mirror 111.

  • Patent number: 5832400
    Abstract: In an apparatus and method utilizing a navigation system for controlling a driving force to be exerted at an estimated position at which the vehicle is to pass to reach to a destination at which the vehicle is finally to reach, a running road estimating block estimates a future position of the own vehicle in which the vehicular driving force controlling apparatus is mounted on the basis of a present position of the own vehicle. The estimated future position is a point of a road for the vehicle to pass several seconds after a time at which the own vehicle is placed at the present position specified from a recorded content of an electronic road map stored in, for example, CD-ROM. A driving force predicting block determines a present vehicular load state derived by a running resistance measuring block as a required driving force at the estimated position by correcting the present vehicular load state by a height difference between the estimated position and the present position.
