Beschreibung
Zusammenfassung:	The invention provides an indoor space actual measurement real quantity index automatic measurement method and device, and relates to the technical field of data processing, and the method comprises the steps: aligning point cloud coordinates (# imgabs0 #, # imgabs1 # and # imgabs2 #) outputted by a laser radar to points (# imgabs3 #, # imgabs4 # and # imgabs5 #) in a world coordinate system through a rotation matrix R by using acceleration information alpha and angular velocity information omega of an IMU; and according to the point cloud coordinates, calculation of actual measurement indexes and removal of error noisy points are carried out. The precision of laser radar measurement data can be improved, real-time point cloud three-dimensional reconstruction and on-line calculation of various actual measurement indexes are carried out on the indoor space, the method can be used for portable and efficient automatic measurement in the civil engineering quality inspection stage, and the labor cost and subjectiv
