After you click this button you will be prompted to provide a description. This value can be changed using the provided table for saved values.
The geometry exported from this measurement tool is the approximated invert.
Remember, all saved measurements can be exported in a variety of formats.
This tool produces reference objects in the form of a line (the selected chord) and a point (the selected crown) in both images. This Clear button can be used to remove these reference objects.
Clearing the reference objects will not remove your ability to save a measurement, but completing subsequent measurement will.
This tool is used to approximate the azimuth (or heading) of the spherical image. This azimuth is the heading directly at the center of the image.
The intial azimuth that you gave the image on loading will be overwritten with this new value.
It is necessary that the relative bearing of an object in the image is known for this tool to work.
Step 1: On either side, use the reticle to aim at an object in the scene with a known azimuth with respect to the image location.
It is not necessary that the target object be the same for any individual image.
The left and right canvases are completely independent of one another during the use of this tool.
Step 2: Use these input forms to enter the target object's heading (do not click enter when entering your value).
It is not necessary that the target object be the same for any individual image.
The left and right canvases are completely independent of one another during the use of this tool.
Step 3: These buttons will start the calculation once you've finished the previous steps.
Your image will be reloaded with the corrected azimuth.
You can always change it back to the original value using the Image Information Panel (don't forget to reload if you do!).
