However, when im trying to run the version 0.1.3, im getting the same warning all the time: <strong>WARNING: failed to track any points</strong>. I even tried to play with the new version 0.1.4 but I got new error and warning: <strong>ERROR in get_data_over_range, requested timestamp must be &gt;0</strong>, <strong>WARNING: Failed to match, dropping frame</strong>.<br />
Could you help me to fix these errors @Matt-Turi?</p>

There is no off the shelf way to do this. You will need to create a to-scale checkerboard that the sensor can see</p>

<p dir="auto">voxl-feature-tracker is a beta project that is under active development, specifically targeting a thermal camera right now. I have not tested with a tof camera, but could you share your config file under <code>/etc/modalai/voxl-feature-tracker.conf</code></p>
