Low FPS in TAG recognition mode on the HuskyLens 2

Check your firmware version first — the latest is v1.2.2 from February. If you're on an early release (some units shipped with 0.9.0), the TAG algorithm may not be optimized yet. The firmware update page has the K230 burning tool and the .img file.
If you're already on the latest firmware, the bottleneck is likely in the AprilTag decoder itself. The algorithm is memory-hungry and scales exponentially with resolution. The HuskyLens 2 runs a 640×480 screen and a 2 MP sensor, so the decoder might be chewing through a much larger frame buffer than the HuskyLens 1 did at 320×240.
