摘　　要：皮革类材质在检测收缩温度时，需要通过测量皮革试样长度的形变量来判定是否收缩．从而锁定收缩时所对应的温度。针对皮革收缩温度测定仪的设计一直面临的精确测量皮样收缩微小位移的技术难题．通过视觉技术结合光学器件，非接触性地实现微小位移的高精度测量。试验结果表明可以达到0．01mm精度的要求，证明该方法具有可行性。During leather shrinkage temperature testing, the length changes of leather samples need to be tested thus determining whether it shrinks, so as to determining the shrinkage temperature. The accurate measurement of leather samples＇ mini length changes is the technical problem of leather shrinkage temperature testing. The non-con- tact high-precision measurement of small displacement is achieved by using visual technology and optical device. The results show that the proposed method is feasible and can meet the requirement of O. Olmm precision.
