@Alexander, thank you for sharing a screenshot of the rayCloud.
It looks like you are unable to see your ground control points in your images for a different reason than Brian. In Brian’s case, the images did not appear in the Properties Menu because of a significant discrepancy between the images’ computed position, which was largely defined by the images’ geotag, and the ground control points’ initial position, which is defined by the measurements that you collected onsite.
I anticipate that you do not see any images in the Properties Menu because Pix4D Desktop is not normalizing the images correctly for the sake of visualizing them in the software’s interface. If that is the case, you can get back up and running with the following modifications to your project’s .p4d.
- Save the project and close Pix4D Desktop
- Open the project’s .p4d file with a text editor, e.g. Notepad
- Find the
<cameraModelSource> line and enter the following string directly above this line:
<pixelValue pixelType="uint16" min="0" max="0"/>
Save the modified .p4d file and close the text editor
Launch Pix4D Desktop
Reopen the project via the modified .p4d file
Verify that you can see the image content in the image thumbnails in the Properties Menu by selecting a ground control point or in the rayCloud's 3D environment (you'll notice that all of the image thumbnails are black in the rayCloud's 3D environment in the screenshot that you shared).
If you do not see any difference in the visualization of your images, please process Step 1 again so that the new image normalization can be taken into account. The recommended modification should enable you to see your image content and should have no effect on your project's results.
Please let us know if you can see images in the Properties Menu after changing the project's image normalization settings.
