本文介绍了使用Halcon进行3D视觉断差（高度差）测量的方法，包括实现效果展示、滤波处理、深度图转换以及高度差的计算。涉及的函数有abnormity_filter用于滤波，DepthMapTransformationPointCloud进行深度图转换，difference_height计算高度差。此外，还提到了相关的咸鱼账号tbNick_mtm4n。

计算函数:difference_height

实现效果
- 显示效果
- 输出结果

代码

主函数:dome

import '.'
gen_image_surface_first_order (Image, 'real', 1, 0, 0, 0, 0, 90, 90)
dev_update_window ('on')
dev_get_window (WindowHandle)


read_image (image_Height, '1H.tif')
read_image (image_Gray, '1G.tif')
*3D相机x, y, z分辨率
xResolution:=0.1024
yResolution:=0.1024
zResolution:=0.0008

ScaleFactor:=[xResolution,yResolution,zResolution]
dev_display (image_Gray)

*采样区域_基准区域
create_drawing_object_rectangle2 (300, 120, rad(90), 30, 20, DrawID)
set_drawing_object_params (DrawID, 'color', 'forest green')
set_drawing_object_params (DrawID, 'line_width', 1)
attach_drawing_object_to_window (WindowHandle, DrawID)

*采样区域_测量区域
create_drawing_object_rectangle2 (300, 120, rad(90), 30, 20, DrawID2)
set_drawing_object_params (DrawID2, 'color', 'red')
set_drawing_object_params (DrawID2, 'line_width', 1)
attach_drawing_object_to_window (WindowHandle, DrawID2)

stop ()

*获取基准区域的参数并生成区域
get_drawing_object_params (DrawID, ['row','column','phi','length1','length2'], GenParamValue)
gen_rectangle2 (Region_Zero,GenParamValue[0], GenParamValue[1], GenParamValue[2],\
                GenParamValue[3], GenParamValue[4])

*获取测量区域的参数并生成区域
get_drawing_object_params (DrawID2, ['row','column','phi','length1','length2'], GenParamValue2)
gen_rectangle2 (Region_Delete,GenParamValue2[0], GenParamValue2[1], GenParamValue2[2], \
                GenParamValue2[3], GenParamValue2[4])


*从HALCON窗口中分离现有的图形对象
detach_drawing_object_from_window (WindowHandle, DrawID)
detach_drawing_object_from_window (WindowHandle, DrawID2)

stop ()

*'single':输入区域根据区域个数单独滤波 而不是对整体滤波 输入其他参数将union后再进行滤波
*滤波的目的是去除掉部分异常值
abnormity_filter (image_Gray, Region_Zero, out_RegionZero, 3, 3, 'single')

abnormity_filter (image_Gray, Region_Delete, out_RegionDelete, 3, 3, 'single')


*计算代码
difference_height (image_Height, out_RegionZero, out_RegionDelete, ScaleFactor,\
                   out_MaxValue, out_MeanValue, out_MinValue, out_Result)
