Hi,

This is a large sequence of images from a drone in the forest:

This image computing looks like SLAM (Simultaneous Localization and
Mapping) method. We obtain both the location (trajectory) and the
visible relief (3D depth map). However, we're dealing with a monocular
(single camera) image sequence, not a stereoscopic (human vision) one.

The sequence is constituted of 10 000 images at 60 frames per second.
It is both large and high-resolution.

Here's the drone's trajectory in space: <https://skfb.ly/pDCwR>

Best regards,

This is a sequence of images from a drone in the forest:

The drone flies very slowly compared to the acquisition rate of 30
frames per second. This makes it much easier to observe the trajectory
and visible depth. The successive images in the sequence are highly
correlated. It is not necessary to frequently reset the reference image
selection over time, as the correlation between this image and
subsequent images remains well above the 60% threshold chosen for
resetting.

Best regards,
