Large scale photogrammetry projects

[[Ca...]]

I've a large photogrammetry and scanning task upcoming and wanted to get views on the size of coded targets that people use with there Tritop systems?

Hello Mr. Mason,

this is difficult to answer, because it depends on the focus distance, lens and resolution of your tritop system:

Simple answer: Just get sure that, the diameter of the un/coded points is about 10 pixels. Take one image at

a meaningful distance of your part and check the pixel-diameter of your points. 

Then adjust the focus distance or use larger/smaller points. 

What about the size of your part? What diameters of points are available at your site?

Best regards,

Jens Heidler
