Harris Filtering Support #248
Comments
+1 for this getting prioritized sooner than later. |
This is now possible on luxonis/depthai-python#317
|
Testing this with dai::FeatureTrackerConfigData::CornerDetector::SHI_THOMASI doesn't succeed. The first few frames of tracks show up when printing, but then no new tracks appear. Sometimes it starts at the beginning for a few frames, then ends for a while, then starts back up after 10 seconds or so. Inconsistent. |
After working with it more it appears there is a temporal filter on the quantity that are on screen at any one time and they are slowly added, one at a time till tracking a few hundred on an 800_P frame in my environment. They do look cleaner than the harris corners. Nice! |
Well, that might have just been because I was running the Left tracker with SHI_THOMASI and the right one with HARRIS for comparison. Setting them both to SHI_THOMASI seems to solve the issue. Sorry for the noise! |
Implemented in: luxonis/depthai-python#317 |
Start with the
why
:Corner detection (Harris corner filtering) is often useful in a variety of CV/AI pipelining usecases and DepthAI has hardware which allows hardware acceleration of this CV function.
