Hi,

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.

Best regards,
