ContextInsights in Orbit3DM Feature Extraction Pro

Concepts

Jobs

A ContextInsights job will leverage machine learning to execute different types of detection in your reality data. There are various types of jobs available in Orbit Feature Extraction Pro:

  • Image 2D Objects: Will detect elements as regular 2D-bounding boxes in images
  • Image 2D Segmentation: Will detect regions in images and deliver segmented raster
  • Point Cloud 3D Segmentation

Each job type requires a suited detector to be executed on reality data

Detectors

A detector is a frozen model that is pre-trained by Bentley Systems. Running on your reality data through a ContextInsights job, it will automatically recognize elements of interest. List of pre-trained detectors is available here:

A detector is specific to a certain job type. The quality of the detection will depend on the similarity between your dataset and the training dataset’s description.
