NOTE

Use a raw image writing tool (for example, Win32DiskImager) to copy

these files from Windows OS to Linux OS (i.MX board) via an Ethernet

cable.

6. System calibration

The system calibration is performed using the Automatic Calibration application. It is a one-shot, stand-

alone application which executes the whole preprocessing calculation and generates the “mask” and

“array” files for texture mapping located in the /App/Build folder finally.

6.1. Arrangement

To perform the extrinsic calibration of the 4-camera system, a square poster of a known size is used

(see Figure 11).
