Example values

(2.5m,2.1m,0.1rad)

Frequency of generated data in operation

2Hz.

 

Name

2D Position and orientation from RFID alone

Description of the information measured

2Hz.

 

Name

2D Position and orientation from the fused algorithm

Description of the information measured

The 2D Position and orientation estimated using both IMU and RFID by trajectory matching.

Units

Position (meters), orientation (rad)

Example values

(2.5m,2.1m,0.1rad)

Frequency of generated data in operation

2Hz.

 

  1. 1. 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…).
  2. A log_file containing several arrays that include: [accelerations, angularRates, RSS, Pos, Pos_RFID, Pos_Fused] at different sampling intervals (100Hzfro raw IMU data, 1Hzpor RFID data, and 2Hz for positions).

Files:

-          One text file with the data sent to the server by TCP/IP

-          One file containing all intermediate samples in mat format (a binary Matlab format).
