  • What is 3D reconstruction in computer vision?

    In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction.

  • How is 3D reconstruction done?

    3D reconstructions can be obtained by directly interfering with the environment using light projectors. Active reconstruction systems that include an integrated RGB camera are called RGB-D sensors as both a color and a depth value can be associated with each image pixel.

  • Why is 3D reconstruction useful?

    Three-dimensional object reconstruction
    Reconstruction allows us to gain insight into qualitative features of the object which cannot be deduced from a single plane of sight, such as volume and the object relative position to others in the scene.
  • A cornerstone technology for the Metaverse is 3D reconstruction—capturing real-world objects and environments in digital 3D form. This process involves a blend of hardware, software, and algorithms to create accurate virtual replicas.
