The invention discloses a three-dimensional point cloud data acquisition device and a three-dimensional point cloud data acquisition method by means of a two-dimensional laser scanner, wherein a coordinate conversion method of laser point cloud data from two-dimensional data to three-dimensional data is presented. Influences of factors such as sensor working mode difference and hardware process level to a conversion process are analyzed, and furthermore a corresponding settlement method is presented. The settlement method comprises the steps of approximating true speed of a turntable through Kalman filtering; correcting serial-port data acquisition time; compensating an angle change amount of a laser point in one period; and calculating angle deviation and position deviation of the laser scanner in a horizontal axis and a longitudinal axis. Experiments represent a fact that a spatial three-dimensional point cloud structure can be accurately acquired in static three-dimensional laser scanning by means of a rotating platform. In moving scanning, because of relatively small size, the position of a moving platform can be obtained through data registration in acquiring the three-dimensional data, thereby realizing synchronous map acquisition and positioning.
