中文摘要:针对三维表面粗糙度评定中表面测量数据量大且计算复杂度高,常用处理方法不能满足实时测量要求的问题,提出了一种基于图形处理器(GPU)的三维表面形貌测量数据快速评定方法,应用CUDA平台开发了基于GPU的并行处理算法,在此基础上实现了三维表面质量的快速评定。实验结果表明,该方法在保证计算精度的同时,运算效率提高了60倍以上,可满足三维表面质量在线评定的要求。

Abstract:Aimed at achieving real-time evaluation on 3-D surface which is difficult due to the large number of surface information and high computational complexity, a GPU-based fast evaluation method was investigated. Rapid surface quality evaluation was realized by the GPU-based fast evaluation method developed by CUDA. The experimental results indicate that the method can significantly improve the calculation efficiency while ensuring the accuracy. It can meet the requirements of online assessment on 3-D surface quality.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
