通过halcon助手读取文件夹图片，做减法处理

两张图片相减，显示灰度值不同的区域

增加三种方法手敲

第一种方法
ImagePath:=[]
ImagePath[0]:='D:/images/by000.bmp'
ImagePath[1]:='D:/images/by001.bmp'
ImagePath[2]:='D:/images/by002.bmp'
ImagePath[3]:='D:/images/by003.bmp'
ImagePath[4]:='D:/images/by004.bmp'
ImagePath[5]:='D:/images/by005.bmp'
ImagePath[6]:='D:/images/by006.bmp'
ImagePath[7]:='D:/images/by007.bmp'

for i:=0 to 7 by 1
   read_image(Image,ImagePath[i])
endfor


第二种方法
for i:=0 to 7 by 1
   read_image(Image,'D:/images/'+i+'.bmp')
endfor

第三种方法

NumImages :=8

for I :=1 to NumImages-1 by 1

   read_image (Image, ' D:/images1/a ' + I$'03d')

endfor
