Handball Field Keypoint Annotation
Budget: €30 – €250 EUR
I have a series of photos that focus exclusively on handball field elements, and I need precise keypoint annotations for two things only: every goal and every court line or marking that appears in each frame. 13 keypoints. Players or other objects do not need to be touched.
Your task is to open each image, place consistent keypoints on the selected structures, working on Roboflow platform.
Deliverables
• Annotated image set (keypoints rendered or in a sidecar file)
• Single JSON or CSV file containing all keypoint coordinates, grouped per image
• Brief read-me describing the keypoint order and any tool you used
Acceptance criteria
• Every visible goal and every court line/marking has its full set of keypoints—no misses, no extras
• Pixel-level accuracy; keypoints must sit directly on the feature corners or intersections
• File naming matches the original image list exactly
If you already work with tools like Roboflow, CVAT, LabelMe, or Labelbox, you’ll feel right at home here. Let me know how many images you can comfortably turn around per day and which output format you’ll provide, and we can get started right away.
