  • How to do 3D Object Detection?

    Generating a 3D Bounding Box in Computer Vision
    If we're working with cameras, 3D Object Detection can be either based on a single image, or a stereo vision setup. You can learn more about stereo vision through my article here. Usually, the algorithms use involve sending an image to a model that directly outputs a box.

  • What is the difference between 2D and 3D Object Detection?

    Unlike in 2D projections, where perspective changes objects' appearance and their perceived size, in 3D they have a consistent size true to their real-world dimensions, no matter the distance to the sensor. Furthermore, the exact orientation of the object with respect to the sensor's position can be estimated.

  • What are the algorithms for 2D object detection?

    The 2D object detection algorithms are divided into three categories: Anchor-based, Anchor-free, and Transformer-based. The 3D object detection algorithms are divided into four categories: monoculor-based, stereo-based, pseudo-LiDAR-based, and multi-view-based.
  • An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two.
