Data Collection


The data collection tool is used to upload real traffic sign photos in Macau taken from participants. We provide a friendly user interface to label photos for traffic sign areas, which could be visited by participants’ mobile devices. When participants take some photos around, they could upload photo data and label areas on the spot, while the system will automatically recognize other metadata of photos (e.g., time and place). We hope the data collection tool could help participants start training and testing conveniently. For every team, their members can:

  • Upload photos and label the traffic sign areas
  • Check history records and re-label or delete them
  • Export labeled data for Traffic Sign Classification
  • Change password of team account

Due to differences of weather, period, light, angle and other surrounding factors, a traffic sign should have diverse features for analysis to improve the recognition accuracy. We encourage take enough photos for every single sign object to enrich data quality.



The sign samples are following Driving Theory Test (Fascicule I – Traffic Signs) published by Transport Bureau. An instruction is listed in the Help page.
