What causes cameras not to enable?

[Comiso90]

After i align photos, the option to Build Dense Cloud is grayed out and none of the photos have a green check mark.

I highlight a photo and go to Enable Camera but nothing happens.

Did the alignment fail? Its says zero Aligned?

Hello Comiso90,

Cameras are not aligned, so you cannot build dense cloud. Can you provide the processing log related to the Align Photos stage (you can copy it from the Console pane) and also screenshot of the Camera Calibration window from the Tools Menu.

[Comiso90]

Thank you for the help.

It processes for over an hour.

I see in the Console area there is an error: empty value

Hello Comiso90,

In the camera calibration window you've got incorrect values input for the sensor pixel. It should be size of the individual pixel on the sensor in mm, not the size of the sensor.

Usually it's about few microns, like 0.0018 mm, for example. So please change the value according to the camera specification and then re-start the alignment.

[Comiso90]

Worked Great!

THANK YOU
