Traffic Light recognition

Pre-requisites:

  • Vector Map
  • NDT working
  • Calibration publisher
  • Tf between camera and localizer

Traffic light recognition is splitted in two parts

  1. feat_proj finds the ROIs of the traffic signals in the current camera FOV
  2. region_tlr checks each ROI and publishes result, it also publishes /tlr_superimpose_image image with the traffic lights overlayed
    2a. region_tlr_ssd deep learning based detector.
