Lindenthal Camera Traps


This data set contains 775 video sequences, captured in the wildlife park Lindenthal (Cologne, Germany) as part of the AMMOD project, using an Intel RealSense D435 stereo camera. In addition to color and infrared images, the D435 is able to infer the distance (or “depth”) to objects in the scene using stereo vision. Observed animals include various birds (at daytime) and mammals such as deer, goats, sheep, donkeys, and foxes (primarily at nighttime). A subset of 412 images is annotated with a total of 1038 individual animal annotations, including instance masks, bounding boxes, class labels, and corresponding track IDs to identify the same individual over the entire video.

Data format

The videos are captured using an Intel RealSense D435 stereo camera and stored as RealSense rosbag files. Each video contains intensity (RGB at daytime, IR at nighttime) and depth image streams with durations of 15 to 45 seconds at 15 frames per second. The depth images are computed on the RealSense D435 in real-time. Sequences recorded from December 17, 2020 additionally contain the raw left / right IR intensity images to facilitate offline stereo correspondence. The file names correspond to the local time, formatted as %Y%m%d%H%M%S.

A subset of videos is labeled with instance masks, bounding boxes, class labels, and track ids in the COCO JSON format. The first 20 frames of the video were skipped during annotation such that the annotated images are not affected by the automatic exposure process of the D435. After two seconds, every 10th frame was annotated with instance masks and track IDs. Together with the COCO JSON annotation files we provide the corresponding extracted still image files in JPEG (intensity) and OpenEXR (depth) format. The included Jupyter Notebook demonstrates how to load and visualize these images and the corresponding annotations.
