Tiling Pipeline

Single Scale Tiling

Single scale tiling FHD Gstreamer pipeline demonstrates splitting each frame into several tiles which are processed independently by hailonet element. This method is especially effective for detecting small objects in high-resolution frames.

Model

The VisDrone dataset consists of only small objects which we can assume are always confined within an single tile. As such it is better suited for running single-scale tiling with little overlap and without additional filtering.

Options

./tiling.sh [OPTIONS] [-i INPUT_PATH]
  • -i --input is an optional flag, a path to the video file displayed.
  • --print-gst-launch prints the ready gst-launch command without running it
  • --show-fps optional - enables printing FPS on screen
  • --tiles-x-axis optional - set number of tiles along x axis (columns)
  • --tiles-y-axis optional - set number of tiles along y axis (rows)
  • --overlap-x-axis optional - set overlap in percentage between tiles along x axis (columns)
  • --overlap-y-axis optional - set overlap in percentage between tiles along y axis (rows)
  • --iou-threshold optional - set iou threshold for NMS.
  • --sync-pipeline optional - set pipeline to sync to video file timing.

Run

cd $TAPPAS_WORKSPACE/apps/h8/gstreamer/rockchip/tiling
./tiling.sh

The output should look like:
