elevation problem

[fberna]

hello,

I have been surveying a rather large area and did it in two days.

First day around 1000 images, second day 800.

If I import the pictures and align them, I find two planes which are aligned on the x and y coordinates but off by some 40 meters on the z one.

This because the z parameters is taken by the drone from its barometric altimeter.


The cumbersome way is to divide them in two chunks,  reference them with a set of ground points, align the chunks and merge them.

However, aside from the lost time in doing it, I would give up some accuracy, compared to having all the pictures align themselves.

Is there a way to align all the pictures ignoring the elevation parameter?

Hello fberna,

You can uncheck all cameras in the Reference pane prior to the alignment and use Generic preselection option. In this case the coordinate information will be ignored during the Align Photos operation.

Alternatively you can shift all cameras from one of the image sub-sets to fit the elevation level of the second one.

Thank you, my fault. Most obviously...
