Online Length Measurements on an Image of the Shroud of Turin
-- photo taken after the restoration of 2002

You can do online length measurements directly on the image (copyrighted Arcidiocesi di Torino). Its calibration is 1px = 1.985mm.

On the right, the current coordinates $(x,y)$ should be displayed as you move the pointer mouse over the image; with the length in millimeters from the last fixed point. Every time you click on the image, new coordinates are fixed and a length is calculated from the previous coordinates. (You must have Javascript enabled in your browser. Currently it does not work with the Safari browser.)

Unkown coordinates until you click on the image. Unkown coordinates until you click on the image.
