Usage:

• The ImageSampler is in many cases used to verify 2D and 3D reference systems.
• It can be used to resample a specific plane in 3D machine vision

ImageResampler can dynamically resample the image - to look at the dice from the top.

The Calibrator tool is often the first reference when using the ImageResampler.

Demonstration Profile

• ImageMixer - T1 - ImageFilter, Resampler and Division_001.zip

Setup

Reference - Reference system selection

ROI - image for calculation and ROI (region of interest)

• Whole image - ignore ROI settings and use all of the image
• Center-X - x
• Center-Y - y
• dX - height
• dY - width

The ROI can be managed by the buttons

• Paste - paste the ROI from the image to the scorpion clipboard
• Copy - copy the ROI to the image from the scorpion clipboard

Point & Click Clipboard Support

The rectangular ROI is defined by four points.

 One point will change the center point.

 

Output Image

• Output to image - name of image to present result
• Pixel size (pitch) - X and Y - correspondence between input reference units and output image pixels. A value of 1 means one output pixel per input unit, 2 means one output pixel per two input units.
• Resulting image in pixels - the actual image size is shown

Example: An image with reference system in mm will be resampled to a pitch of 1 mm with the default value of 1. With a value of 0.01 the resulting image will have a constant pitch of 0.01 mm. This is independant of the original pixel resolution.
