halcon 1D测量

1. 一维测量基本流程

2. 基本算子

• 提取垂直于矩形的直边

read_image (Image, 'fuse')
get_image_size (Image, Width, Height)
draw_rectangle2 (3600, Row, Column, Phi, Length1, Length2)
dev_set_draw ('margin')
gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)
*产生测量ROI对象句柄
*参数说明
*Row：矩形ROI中心y坐标
*Column：矩形ROI中心x坐标
*Phi：矩形ROI角度
*Length1：矩形ROI长半轴长
*Length2：矩形ROI短半轴长
*Width：测量图像宽
*Height ：测量图像高
*Interpolation ：插值类型
*MeasureHandle：测量句柄
gen_measure_rectangle2 (Row, Column, Phi, Length1, Length2, Width, Height, 'nearest_neighbor', MeasureHandle)
*提取直边缘
*参数说明
*Image：所测量图像
*MeasureHandle：测量句柄
*Sigma：高斯平滑标准差
*Threshold ：最小边缘幅度
*Transition：找点方式。'all', 'negative', 'positive'
*Select：选择的端点。'all', 'first', 'last'
*RowEdge ：输出边缘中心y坐标
*ColumnEdge：输出边缘中心x坐标
*Amplitude：输出边缘幅度
*Distance：输出边缘中心之间距离
measure_pos (Image, MeasureHandle, 1, 30, 'all', 'all', RowEdge, ColumnEdge, Amplitude, Distance)
gen_cross_contour_xld (Cross, RowEdge, ColumnEdge, 6, Phi)
measure_pairs (Image, MeasureHandle, 1, 30, 'negative', 'all', RowEdgeFirst, ColumnEdgeFirst, AmplitudeFirst, RowEdgeSecond, ColumnEdgeSecond, AmplitudeSecond, IntraDistance, InterDistance)
gen_cross_contour_xld (Cross1, RowEdgeFirst, ColumnEdgeFirst, 16, rad(45))
gen_cross_contour_xld (Cross2, RowEdgeSecond, ColumnEdgeSecond, 16, rad(20))

输出结果

• 提取垂直于环形圆弧的直边缘

read_image (Zeiss1, 'zeiss1')
*频率域滤波增加高频使图像增强
