This paper introduces a low-cost, simple structure, and high-convenience 3D microphone positioning system for scanning acoustic field of sound sources. For the inherent errors caused by motors, mechanical fluctuations, and string deformations this work describes an anti-error method based on experimentally measured data to eliminate the corresponding effect. The method can determine a weighting strategy for every measured data and could be extended to any scanning system.
