Second Example implementation on TDA4VM

This SFM based OG mapping application is available in the SDK under the PTK demos section. The documentation for this algorithm can be found here. This particular application constructs a world-centric accumulated 2D OG map, as opposed to the instantaneous map created by the above application. This algorithm uses almost an identical chain to the one described above, with minor differences. A sample output of this application is shown in Figure 8-1. Here, the camera is mounted on the side of the vehicle and also runs on saved data captured in a parking lot inside TI. Here, free cells are marked green, occupied red and unknown black.
