【摘要】 结合江苏省《星火计划》提出的“磁芯材料器件──软磁铁氧体磁芯自动分选线”课题，本文在探讨一种无需精确定位的非接触式在线投影测长算法的基础上，提出了测量算式及方案实施中要解决的主要问题的技术途径。模拟实验表明，本文提出的测量原理、方法和方案可转入技术实施。更多还原

【Abstract】 Based on one of the topics of"Star and Fire Plan"for Jiangsu Province which named auto-matically classifying the magnetic material components──soft magnetic ferrite cores,this paper dis-cusses a new non-contacting method without accurate location location to measure on -line the length of the mag-netic cores.The algorithm for measurement and key techmical points solved in the executing scheme areprovided.The model test shows that the prineiple,the way and the scheme of the measurement are ac-curate and feasible and it can be realized in the engineering.更多还原
