摘　　要：针对掌形识别采集过程存在的掌形平移、旋转、缩放的问题,提出了变换坐标域的概念,将手指轮廓点重新定义坐标.此方法有效的解决了掌形识别过程中存在的三种仿射变化问题,从而去掉了目前采集过程中的固定栓,使得采集过程更加灵活,方便,人性化.Tosolve the shifting, rotating and zooming problems of the in hand geometry recognition, a concept of coordinate domain transformation is put forward in this paper to redefine the hand geometry coordinate. The three affine changes in hand geometry recognition can be eliminated effectively, so the fixed poles widely used in hand geometry acquisition process can be removed to make the process more flexible, convenient and user-friendly.

关 键 词：掌形识别 坐标域变换 仿射变化
