* 读取图像
read_image (Image, 'path/to/your/image.bmp')
* 二值化,调整阈值以分离小珠子
threshold (Image, Regions, 0, 59)
* 连接区域(将相邻的像素点连成一个区域)
connection (Regions, ConnectedRegions)
* 按尺寸过滤区域(根据宽度和面积筛选珠子)
select_shape (ConnectedRegions, SelectedRegions, 'width', 'and', 5, 100)
select_shape (SelectedRegions, SelectedRegions, 'area', 'and', 50, 5000)
* 计算每个珠子的区域中心(质心)
area_center (SelectedRegions, Area, Row, Column)
num_elements (Area, NumberOfBeads) * 统计珠子的数量
* 形态学腐蚀和膨胀,用于分离珠子
erosion_circle (SelectedRegions, RegionErosion, 5)
dilation_circle (RegionErosion, RegionDilation, 5)
* 为储存长轴和短轴直径创建空数组
RA := []
RB := []
* 遍历每个区域,拟合椭圆并提取长短轴信息
gen_empty_obj (EmptyObject)
for Index := 1 to NumberOfBeads by 1
* 获取单个区域
select_obj (RegionDilation, ObjectSelected, Index)
* 生成区域轮廓
gen_contour_region_xld (ObjectSelected, Contours, 'border')
* 拟合椭圆并计算长轴、短轴
fit_ellipse_contour_xld (Contours, 'fitzgibbon', -1, 0, 0, 200, 3, 2, Row1, Column1, Phi, Radius1, Radius2, StartPhi, EndPhi, PointOrder)
* 存储长轴和短轴
RA := RA.TupleConcat(Radius1 * 2) * 长轴直径
RB := RB.TupleConcat(Radius2 * 2) * 短轴直径
* 显示拟合的椭圆轮廓
gen_ellipse_contour_xld (ContEllipse, Row1, Column1, Phi, Radius1, Radius2, 0, 6.28318, 'positive', 1.5)
concat_obj (EmptyObject, ContEllipse, EmptyObject)
endfor
* 显示结果
dev_display (EmptyObject)
stop()
