The purpose of this disclosure is to easily calculate draft information with a simple configuration. The draft information generation device (10) comprises multiple range-finding sensors (20) and an information processor module (30). The range-finding sensor (20) is mounted on the side of a vessel (80) and measures the distance to water surface (91) using a range-finding signal. The information processor module (30) calculates draft height Hdr using the distance to the water surface (91) and the mold depth Hmd of the vessel (80).

A device for producing a triangular laser sheet. The device has an optical transmitter with a pair of plano-convex cylindrical lenses for circularizing infrared laser light and a plano-concave cylindrical lens for shaping the circularized light to produce a triangular laser sheet. A tilt sensor measures departure of the triangular laser sheet from a horizontal reference. The device projects a triangular sheet of infrared light that is useful for detecting over-height vehicles that are approaching a structure, such as a bridge.

The present technology relates to an imaging control device and method, and a vehicle that enable distance measurement with higher accuracy. An imaging control unit controls imaging by a stereo camera system including at least a set of cameras arranged in a vertical direction, the set of cameras including at least one camera arranged to have an optical axis directed obliquely downward, and a monitoring processing unit performs monitoring processing on the basis of an image captured by the stereo camera system. For example, distance measurement processing is performed on the basis of an image captured by at least the set of cameras arranged to have at least one optical axis directed obliquely downward on a side surface of the vehicle. The present technology can be applied to driving assistance of a vehicle.

A method for measuring a measurement distance between a rotating laser, which emits a first laser beam that can be rotated about a rotational axis and/or a stationary second laser beam, and a laser receiver, which has a detection field with a measurement function. The rotating laser is inclined in a direction of inclination by an inclination angle. The position of incidence of the inclined laser beam on the detection field of the laser receiver is determined as a measurement point. The distance between the measurement point and a zero position of the detection field is stored as the height, and the measurement distance between the rotating laser and the laser receiver is determined using the inclination angle and the height.
