Abstract

The authors examine the concept of the orientation of a 2D object from three points of view; a direct axis of geometric shape, the principal axis defined in terms of the principal second movements of area, and the major axis of the fundamental ellipse fitting the boundary of the object. The three methods are implemented on a vision workstation and applied to samples of Pacific salmon. The results are compared with direct measurement orientation. The three methods of orientation measurement are evaluated quantitatively using these results, with respect to accuracy, speed of measurement and appropriateness under various practical conditions.<>
利用图像处理测量方向,并应用于自动化鱼类加工
作者从三个角度考察了二维物体方向的概念;几何形状的直轴,根据面积的主要二次运动定义的主轴,以及拟合物体边界的基本椭圆的长轴。这三种方法在视觉工作站上实现,并应用于太平洋鲑鱼样本。结果与直接测量取向进行了比较。利用这些结果定量地评价了三种取向测量方法的精度、测量速度和在各种实际条件下的适宜性。
