Stanford Drone Dataset

The Stanford Aerial Pedestrian Dataset consists of annotated videos of pedestrians, bikers, skateboarders, cars, buses, and golf carts navigating eight unique scenes on the Stanford University campus: https://cvgl.stanford.edu/projects/uav_data/

Scenes

The eight scenes are:

  • bookstore
  • coupa
  • deathCircle
  • gates
  • hyang
  • little
  • nexus
  • quad

Each video for each scene in the videos directory has an associated annotation file (annotation.txt) and exemplary frame (reference.jpg) in the annotations directory.

Annotation File Format

Each line in the annotations.txt file corresponds to an annotation. Each line contains 10+ columns, separated by spaces. The definition of these columns are:

1   Track ID. All rows with the same ID belong to the same path.
2   xmin. The top left x-coordinate of the bounding box.
3   ymin. The top left y-coordinate of the bounding box.
4   xmax. The bottom right x-coordinate of the bounding box.
5   ymax. The bottom right y-coordinate of the bounding box.
6   frame. The frame that this annotation represents.
7   lost. If 1, the annotation is outside of the view screen.
8   occluded. If 1, the annotation is occluded.
9   generated. If 1, the annotation was automatically interpolated.
10  label. The label for this annotation, enclosed in quotation marks.

Homography

In order to project the trajectories into real-world coordinates, you should use the values provided in estimated_scales.yaml.

  • Note: The certainty values, are supposed to recall if the scale is reliable or not. Some of the scales are estimated using google maps, and some are just a rational guess!

Load Dataset with Toolkit

In order to the load the datasets, we provided the loader_sdd.py

import os, yaml
from toolkit.loaders.loader_sdd import load_sdd, load_sdd_dir

scene_name = 'hyang'
scene_video_id = 'video6'
# fixme: replace OPENTRAJ_ROOT with the address to root folder of OpenTraj
sdd_root = os.path.join(OPENTRAJ_ROOT, 'datasets', 'SDD')
annot_file = os.path.join(sdd_root, scene_name, scene_video_id, 'annotations.txt')

# load the homography values
with open(os.path.join(sdd_root, 'estimated_scales.yaml'), 'r') as hf:
    scales_yaml_content = yaml.load(hf, Loader=yaml.FullLoader)
scale = scales_yaml_content[scene_name][scene_video_id]['scale']

traj_dataset = load_sdd(annot_file, scale=scale, scene_id=scene_name + '-' + scene_video_id,
                        drop_lost_frames=False, use_kalman=False)
