Re: Colab Import Error

There was a bug in the latest version of scipy. I fixed the scipy version and it should work now. Let us know otherwise.

Re: Failed to run gait analysis through Python

We are looking at peaks in processed marker data.

> And how can I change the visualization output to data output in CSV format?
There are some python modules to output csv files.

Re: Failed to run gait analysis through Python

Hi that sounds good. It is very difficult to find settings that work for all cases. Playing with the settings of the detect_gait_peaks function is probably the way to go: https://github.com/stanfordnmbl/opencap ... 90C13-L703

Re: Gait Analysis Code Fail

You are probably not in the right conda environment (base instead of opencap-processing) or something like this.

Re: About cameraintrinsicsextrinsics.pickle file.

Hi, The camera intrinsics are specific to your hardware and to the settings you use when taking the video. We fix them in OpenCap, which allows us to load them from the database. If you use videos not recorded using OpenCap, you will need to compute them somehow. For reference, we use this code to d...

Re: Failed to run gait analysis through Python

hi, I just tested and the gait analysis tool does not seem to be working for your trial with data from children. I have opened an issue, and I will look into that within the next few weeks. https://github.com/stanfordnmbl/opencap-processing/issues/119. I will report back here if I find a solution. A...

Re: Synchronize question

We tested different methods (time delay that maximizes cross-correlations of marker velocities and time delay that minimizes Euclidian distances) to compute the time delay between the two systems, and we selected the method that gave us the lowest error in marker position between the two systems. Do...
