It's possible to reconstruct visible relief, and trajectory from the Ingenuity drone, using a simple video sequence. The monocular disparity
is obtained by matching images with a reference, measuring optical-
flow. The trajectory is obtained using parameters of the perspective transformation describing successive images...

Since April 19, 2021, the Ingenuity helicopter sent to Mars hasn't
stopped flying over the planet. It was expected taking off only
5 times, to demonstrate that it was possible. In fact, we are in
February 2022, and a final realization of 19th flight over Mars, was attempted. The measurements we take correspond to the 18th flight
over planet Mars, dated 15 December 2021.
The localization of the piloting assistance camera which is obtained,
is not perfect. The lens of this camera has a radial distortion, what
is not taken into account by the perspective kinematics model.

It was planned June 11, 2022, the 29th flight over planet Mars, but
Martian atmospheric conditions produced a failure. Since that, NASA and Ingenuity took winter's vacations, which had not been the case during
2021 summer holidays. The seasons on Earth are different from those on
planet Mars.
Then on August 19, 2022, the 30th takeoff of the helicopter took place:

It gave a brief video, because the takeoff was intended to remove
dust from Ingenuity, after its long period (2 months) of inactivity.
Then on September 6, 2022, the 31st flight over Mars took place:

A video has reached us, and image processing have been processed.
The flying machine survived the Martian winter, which is confirmed
by success of the 32nd flight, on September 18, for which we have
no video yet from Caltech/JPL/NASA lab. This is a spatial experience
that extends beyond all hope :-)

We are in August 2023, and the Ingenuity helicopter still flies over
Mars. There's no GPS satellite system on the planet, and a very little atmosphere compared to Earth, but it is localizing itself with a
grey-scale camera that points to the ground, and it works like that...
Here is a video <https://www.youtube.com/watch?v=TP_ojUa6XtU>
The image processing computations are obtained from interpolation
performed at <https://twitter.com/stim3on/status/1419414689998594051>
by Simeon Schmauß. That's because video are too sparse when it is
transmitted down the JPL/NASA Laboratory at Caltech University...

Ingenuity made its 55th flight on August 12, 2023, what demonstrates the robustness of the control GNU/Linux system, including in particularly
hostile conditions, an unknown environment and minimal supervision,
because the helicopter is almost autonomous, very very far from
everything somewhere in space.
