在这个示例代码中,我们使用find_shape_model_3d操作符来查找3D形状模型在输入图像中的匹配位置。参数1到参数5依次是算子的输入参数,参数6和参数7是算子的输入参数(在示例中使用了一个包含两个元素的数组),参数8到参数10是算子的输出参数。 Image是输入参数,表示待搜索的输入图像。 ShapeModel3DID是输入参数,表示3D...
例如,对于基于形状的匹配,你可以用clear_shape_model去销毁它。 // // File generated by HDevelop for HALCON/DOTNET (C#) Version 10.0 // using HalconDotNet; namespace VsHelper { void Match() { HTuple Width, Height, WindowHandle3, Row1, Column1, Row2, Column2, hv_ModelId,row,col,angle,s...
halcon中的find_shape_model算法基于边缘梯度相似性进行模版匹配,在处理2D刚体变换时具有很好的效果,如果匹配的物体存在大小缩放时则可以应用find_scaled_shape_model()和find_aniso_shape_model()等算法。 但上面提及的算子在处理物体存在变形时效果不好,虽然find_shape_model()的SubPixel参数支持设置一个max_deformatio...
更具体地说,find_scaled_shape_model在进行计算机视觉和图形学任务时,如模板匹配等,能够根据不同尺度对3D模型进行尺度变换,同时保持其原有形状。它不同于find_shape_model(行列方向均无缩放的模板匹配)和find_aniso_shape_model(行列不等比例缩放(各向异性缩放)的模板匹配),find_scaled_shape_model在进行模板匹配时...
HALCON中最实用的算子find_shape_model,该算子通过模板在图像中寻找没有几何缩放的目标。本文重点对其主要参数进行了归纳整理。通过对该参数的分析,得出通过优化匹配角度、金字塔层数以及贪婪度可减少模板寻找的时长。 find_shape_model(Image : : ModelID, AngleStart, AngleExtent, MinScore, NumMatches, MaxOverlap...
探究算子find_shape_model中参数MaxOverlap的准确意思 基于形状的模板查找算子: find_shape_model(Image : : ModelID, AngleStart, AngleExtent, MinScore, NumMatches, MaxOverlap, SubPixel, NumLevels, Greediness : Row, Column, Angle, Score) MaxOverlap:意思是允许的最大... ...
halcon中的三维匹配大致分为两类,一类是基于形状的(Shape-Based),一类是基于表面的(Surface-Based)。基于形状的匹配可用于单个2D图像中定位复杂的3D物体,3D物体模型必须是CAD模型,且几何边缘清晰可见,使用的…
