Calculating point cloud object volume using the co-opposite-direction slicing method
Although the Slicing Method (SM) is effective for calculating the volume of point cloud objects (PCOs), it is restricted in terms of applicability and practicability because of certain contingencies and directional defects. The paper proposes the Co-Opposite-Direction Slicing Method (CODSM) an improved method that calculates PCO volume by increasing parallel (co-opposite-direction) observation and considering the two-way mean as the result. The proposed method fullyexploits the mutual offsetting of random errors and the compensation of systematic directional errors, which can effectively overcome (or mitigate) the effect of random errors and reduce the effect of systematic errors in SM. Two typical objects, a cone model and a stone lion base, are used as examples for calculating the PCO volume using CODSM. The results show that CODSM has all the inherent advantages of SM and effectively weakens the volatility of random errors and the directionality of systematic errors from SM, which verifies that CODSM is a robust configuration upgrade of SM.
