Name of the competing system: iLoc+
Name and email of the responsible person: Stefan Knauth
Date and place: Stuttgart, 25.6.2012
Name | Sensor Raw Data |
Description of the information measured | Ultrasound Time of Flight Data The data Stream received from the about 26 sensors Data is in text format, each line is a dataset and contains: relative time stamp, sensor id, slot number, and the TOF times of the four slots preceeding the current time slot. A time slot is about 50 ms long. |
Units | relative timestamp is a integer number, counting in units of 100 usec the time which has passed since the receiver has been switched on each TOF value is a 4 hex digit number giving the ultrasound time of flight in units of 1 usec, |
Example values |
|
Frequency of generated data in operation | Every 50 msec a dataset is generated. |
Name | Calculated position data raw |
Description of the information measured | Every 50 msec a raw position is calculated and written to the log Dataset contains: time when line is written, slot# and relative reception time of last dataset, calculated position xyz, involved sensor id's |
Units | centimeters |
Example values |
|
Frequency of generated data in operation | Generated every 50ms. |
After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).
- An array of arrays that include: [time, accelerationValue, angularRateValue], every 100ms.
- Others…
Files:
- iloc_sensor_data.txt // append-only file which logs all raw data
- iloc_raw_pos.txt // append-only file which logs all calculated raw positions
- iLoc_xmitted_pos.txt // append-only: this is a log containing the information transmitted to the socket adapter
- iloc_mean_tof_calib.txt // this contains sensor readings generated during calibration phase
- iloc_fixed_nodes_pos // Read Only: this is a pre-engineered file containing positions where reference nodes and marker nodes are/shall be placed
- iloc_nodes_pos // this is the file where the system-estimated node positions are stored after the auto-calibration phase
