Question

我在图像上绘制一条线，我希望将线分开/划分5次并得到5点坐标，在脚本中我有线坐标，但我不知道如何继续。我将不胜感激任何帮助。感谢

clc;
clear all;

figure, imshow('pout.tif');
h = imline;
lineEndPoints = wait(h);

x1 = round(lineEndPoints(1,1),2);
y1 = round(lineEndPoints(1,2),2);
x2 = round(lineEndPoints(2,1),2);
y2 = round(lineEndPoints(2,2),2);

Answer 1

它只是将线分成5个相等的段吗？

>> x = lineEndPoints(1:2,1)

x =

    32
   327

>> y = lineEndPoints(1:2,2)

y =

    48
   485


>> a = (0:5)/5

a =

         0    0.2000    0.4000    0.6000    0.8000    1.0000

>> x = x(1) + (x(2)-x(1))*a

x =

    32    91   150   209   268   327

>> y = y(1) + (y(2)-y(1))*a

y =

   48.0000  135.4000  222.8000  310.2000  397.6000  485.0000
