Abstract: A ship cabin loading capacity measurement method and apparatus thereof, comprises: acquiring point cloud measurement data of a ship cabin; optimizing the point cloud measurement data according to a predetermined point cloud data processing rule, and generating optimized ship cabin point cloud data; calculating said ship cabin point cloud data with a predetermined loading capacity calculation rule, and getting ship cabin loading capacity data. According to the ship cabin loading capacity measurement method of the present invention, the point cloud measurement data can be acquired by a lidar, and processing the point cloud measurement data of the ship cabin with a predetermined point cloud data processing law and a computation law, and as the point cloud data processing law and the computation law can be deployed in a computer device in advance, after point cloud measurement data acquisition, loading capacity of a ship cabin can be acquired quickly and precisely.

Abstract: A device for measuring volume of spherical tanks, includes a base, four supporting rods, a driving mechanism, a rotating disc and a counterweight mechanism. The base is provided with a first through hole and a circular fixing base with a second through hole. The supporting rods are circumferentially provided on the fixing base, with a sliding rod slidably provided at the lower side. An outer end of the sliding rod is provided with a limiting plate. The driving mechanism can drive the sliding rods to move simultaneously in radial directions. The rotating disc with a third through hole is arranged on the fixing base, and is rotatably provided with a reel around which a steel tape is wound. A free end of the steel tape is provided with a balancing disc whose opposite sides are provided with laser rangefinders. The counterweight mechanism can keep the balancing disc stable.
