Title: Undersea acoustic positioning system
Inventor: WADA TOMOHISA
IPC: G01S5/20
Filed: 2021-09-14
Abstract: To measure underwater coordinates of subdevices such as AUV cruising underwater by only two points in total, a first reference point defined as a ship at seat and a second point defined as a buoy towed by the ship.SOLUTION: An undersea acoustic positioning system comprises two reference points of a first reference points and a second reference point that are served references for positioning points and located on the water, and two or more subdevices cruising in water. The subdevices execute: a distance calculation step of calculating a distance between the first reference point and each subdevice, a distance between the respective subdevices, a distance between the second reference point and each subdevice, and a distance between the respective subdevices based on a transmission time when each reference point transmits an acoustic signal and a reception time when each subdevice receives the acoustic signal; and an underwater coordinates determination step of determining underwater coordinates of the subdevice from absolute coordinates received from the respective reference points, a dive depth measured by a depth sensor and an arrival direction of an acoustic signal transmitted from the other subdevice detected by a transducer. Thereby, the undersea acoustic positioning system measures the underwater coordinates of the respective subdevices.SELECTED DRAWING: Figure 1

Title: Laser beam projector and three-dimensional image reproduction method
Inventor: ITO MANABU
IPC: F21S2/00
Filed: 2021-08-10
Abstract: To solve the problem in which: various methods are researched for an imaging technique to show images not in two-dimensional (flat surface) images but in three-dimensional (stereoscopic) images; however, complete three-dimensional (stereoscopic) images are not reproduced in terms of clearness of the images and shape reproducibility.SOLUTION: Image data is obtained by photographing an object with a plurality of cameras from 360° degrees, deleting overlapping images, and editing resulting images as three-dimensional (stereoscopic) images, and the image data is projected by a plurality of projectors toward one point from the 360° directions. A method is proposed for reproducing the three-dimensional (stereoscopic) images on a space where the rays of light intersect with each other. Normally, a projector projects and reproduces images on a screen with illumination light from a light source such as an LED, but in this method, the projector projects and reproduces the images at a specific position of the space with a laser beam from a light source. Since the laser beam is a beam that does not diffuse and has high straightforwardness, images to be reproduced have high sharpness, which solves the problem in a conventional stereoscopic imaging technique.SELECTED DRAWING: None
