Creating a Calibration
Once you have created your session - you'll now need to add a Calibration to it. This stage is necessary as the calibration information initialises the aim platform's computational measurements of the human body and the capture area. For guidance on how to calibrate - press here!
Select the '+ Calibration' icon
Make sure you add the information below
Title: Give your calibration a title
Description: If you wish, you can also add a description
Calibration Actor Height: You must do this in order for the system to accurately extract a person's bone lengths - this information is required in metres (i.e. 1.88m)
Time sync clapping starts: This is the time in the calibration when the clap for syncing starts - this helps to sync all the cameras
Time sync clapping ends: This is the end time of the clap - this will help the system synchronise more easily
Time calibration sequence starts: This is the start time of the calibration
Time calibration sequence ends: This is the end time of the calibration sequence
Hit 'run' and you'll be notified when your calibration is done.
At time of publication - we estimate a 30 second calibration to take 1hr to process.
Clap Sync Explained
When using GoPro Hero8 or Hero9 cameras, the aim platform requires performers to clap at the beginning of a calibration or a take. The aim platform looks for the audio peak from the clap and automatically synchronises all clips for that calibration or take. The aim platform prompts you to set a Clap Start Time and a Clap End Time. Setting this time range i.e. from 00:01 to 00:04 in your Calibration or Take helps narrow down the system’s automatic search window.
Calibration & Take Start/End Time Explained
The aim platform allows you to specify the time range of the take that you wish to extract motion for. I.e. if you have a clip that is 2 minutes (timecode: 02:00) long but you only wish to extract motion for a sub-range such as 00:05-01:10 then you can specify this in the aim UI.
It is best practice to clap at the beginning of any Calibration or Take performance that is undertaken. This allows you to easily search for the Start/End times for both the clap and/or the Calibration/Take.
