So I've played with the different ways of doing PLL in liquid.
There are two methods I can see:
- use NCO object which uses a very simple model (Costas loop?)
- use method described in https://liqu…

Hi sergiobd,
Thanks a lot for sharing. I have been able to get the data for a single vive tracker following your tutorial. But this data will shake. Because I want to control the camera using its dat…

在论文里，提到用kalman预测了tracks的新位置，14-16行。
但在代码里，并没有用到预测的新位置。
`# Predict the current location with KF`
` STrack.multi_predict(strack_pool)`
` dists = matching.iou_distance(strack_pool, detections)`

I've been toying with the following SIR-type model in my head, and I want to write it down. The goal is to encapsulate as much of the standard epidemic structure in some time varying parameters. Let `…

The platform may expose both fused and raw(?) sensors. For example, Geolocation is generally a fused sensor (fusing GPS, WiFi, and network data, in a way that's totally opaque to the consumer of the A…

Users don't always have control over the nodes that produce sensor data. Many sensors indicate the absence of measurement of a given variable by inflating its covariance to an extremely large number. …

The sensor-fusion approach of using AHRS taken for the hardware vario described [here](http://pataga.net/imukalmanvario.html) by Hari Nair seems like it would be a good match for improving on the Kalm…
