Purpose

EChecker2 is a golden template inspection algorithm.

This sample program demonstrates how to:

□

Specify the inspection area.

□

Select fiducials for the localization and the alignment of the inspection area.

□

Train the method and apply it on new images.

Code highlights

Initialize an object EChecker2 with a reference image, a vector of ERegion corresponding to the fiducials and an ERegion corresponding to the region to inspect.

// Put fiducial regions in vector
std::vector<ERegion*> fiducials;
fiducials.push_back(regions_[RegionID_Fiducial1]);
fiducials.push_back(regions_[RegionID_Fiducial2]);

// Initialize training
checker_.Initialize(referenceImage_, fiducials, *(regions_[RegionID_Inspection]));

Train the checker with a vector of training images.

NOTE:

As all the parameters of EChecker have an influence on how the model is built, you must restart the model creation if any of these parameters is changed.

// Train
checker_.SetInspectionTolerance(5.0f);
checker_.Train(images);

Inspect an image and filter the list of defects based on their area.

►

The result of a EChecker inspection is an object EasyObject ECodedImage2.

// Inspect Image
checker_.Inspect(image, codedImage_);

// Clear defect selection
defects_.Clear();

// Select defects on area
defects_.AddObjects(codedImage_);
defects_.RemoveUsingUnsignedIntegerFeature(EFeature_Area, 25, ESingleThresholdMode_Less);
