Structured Light-Based 3D Reconstruction System for Plants

Camera-based 3D reconstruction of physical objects is one of the most popular computer vision trends in recent years. Many systems have been built to model different real-world subjects, but there is lack of a completely robust system for plants. This paper presents a full 3D reconstruction system that incorporates both hardware structures (including the proposed structured light system to enha...

Structured Light 3D Surface Reconstruction of Birds

In my research with the Lentink Lab, I am designing a system that will track the 3D surface of the wings of birds using stereoscopic vision implemented using a high speed projector and camera setup at 3000 Hz. In previous studies, laser scanning has been successfully used to map stationary objects [1], [2] and has also progressed for more rapid data collection [3], [4], but has never been used ...

Coded structured light based uncalibrated stereo system

We present a novel uncalibrated active stereo system using coded structured light. Structured-light-based active stereo systems generally consist of a camera and projector that require precise precalibration. If we can eliminate the precalibration process from the system, the user can merely place the equipment arbitrarily and directly begin scanning the objects and it can greatly improve both ...

Structured Light Techniques for 3D Surface Reconstruction in Robotic Tasks

Robotic tasks such as navigation and path planning can be greatly enhanced by a vision system capable of providing depth perception from fast and accurate 3D surface reconstruction. Focused on robotic welding tasks we present a comparative analysis of a novel mathematical formulation for 3D surface reconstruction and discuss image processing requirements for reliable detection of patterns in th...
