摘要：The definition of the quality parameters of a point cloud acquired using the airborne laser scanning is the element of almost every terms of reference involving airborne spatial data acquisition. The quality of the LiDAR data should not be identified only with accuracy and should be examined in a wider aspect taking into account other parameters of the point cloud that was acquired as a result of a flight. For instance the Polish legal regulations provide the requirements concerning the coverage of the strips and the point density. The above mentioned parameters of the LiDAR data can be influenced to some extent by many factors concerning the flight itself such as a varying speed as well as the horizontal and vertical deflections from the planned flight line. However,vibrations and angular deflections seem to influence the point cloud quality to the highest extent. LiDAR data acquisition without required stabilizing system makes keeping the required quality parameters very hard. Within the research project which aimed to develop the prototype of the ultralight,stabilized mapping platform for the gyrocopter,a number of analyses concerning the optimal stabilization scenario were carried out. Tools including scripts and computer programs for analyzing the impact of the deflections on the data quality have been developed. The proper stabilization variant has been established taking into account three separate deflection components,i.e.: roll,pitch and yaw.
