• We are pleased to announce the AGIUSEP 2022 Object Detection in Images Challenge (Task 1). This competition is designed to push the state-of-the-art in object detection with drone platform forward. Teams are required to predict the bounding boxes of objects of ten predefined classes (i.e.pedestrianpersoncarvanbustruckmotorbicycleawning-tricycle, and tricycle) with real-valued confidences. Some rarely occurring special vehicles (e.g.machineshop truckforklift truck, and tanker) are ignored in evaluation. 
  • The challenge containing 10,209 static images (6,471 for training, 548 for validation and 3,190 for testing) captured by drone platforms in different places at different height, are available on the download page. We manually annotate the bounding boxes of different categories of objects in each image. In addition, we also provide two kinds of useful annotations, occlusion ratio and truncation ratio. Specifically, we use the fraction of objects being occluded to define the occlusion ratio. The truncation ratio is used to indicate the degree of object parts appears outside a frame. If an object is not fully captured within a frame, we annotate the bounding box across the frame boundary and estimate the truncation ratio based on the region outside the image. It is worth mentioning that a target is skipped during evaluation if its truncation ratio is larger than 50%. Annotations on the training and validation sets are publicly available.

A team can only register one account. Quota can be obtained by joining the WeChat group.

In order to prevent the problem of a team registering multiple accounts, this competition requires all members of the participating team to join the WeChat group. If the QR code is invalid, we will update it in time. And the old account cannot be used, you need to re-register a new account.

If you do not have WeChat, please send your application to tju.drone.vision@gmail.com. The application information should include account name, real name, institution, country, email address and the name and institution of team members.

Challenge Guidelines

  • The object detection evaluation page lists detailed information regarding how submissions will be scored. To limit overfitting while providing researchers more flexibility to test their algorithms, we have divided the test set into two splits, including test-challenge and test-dev. 
  • Test-dev (1,610 images) is designed for debugging and validation experiments and allows for unlimited submission. The up-to-date results of the test-dev set are available to view on the leaderboard. 
  • Test-challenge (1,580 images) is used for workshop competition. We encourage the participants to use the provided training data, while also allow them to use additional training data. The use of external data must be indicated during submission. 
  • The train+val images and corresponding annotations as well as the images in the test-challenge set are available on the download page. Before participating, every user is required to create an account using an institutional email address. If you have any problems in registration, please contact us. After registration, the users should submit the results in their accounts. The submitted results will be evaluated according to the rules described on the evaluation page. Please refer to the evaluation page  for detailed explanation.
