Automatic morphological trait characterization for corn plants via 3D holographic reconstruction

Corn 3d Reconstruction with Photogrammetry

Corn is a common crop which is often studied in the applications of remote sensing and precision agriculture. In both cases, it is important to know the geometrical structure of the corn, for example, the diameter and height of stem, the leaf areas and leaf directions. It is convenient to measure these geometrical structural data on a 3D corn model. In order to generate such a corn 3D model, an...

3d Reconstruction of Plants

Automatic 3D building reconstruction

We present a knowledge-based system for automatic 3D building reconstruction from aerial images. Our approach relies on combining pairs of stereo images with 2D GIS map and domain knowledge. Since most buildings can be described as aggregation of simple building types, the domain knowledge is represented in a building library containing building primitives (flat, gable, and hip roof building). ...

Digital Holographic Capture and Optoelectronic Reconstruction for 3D Displays

The application of digital holography as a viable solution to 3D capture and display technology is examined. A review of the current state of the field is presented in which some of the major challenges involved in a digital holographic solution are highlighted. These challenges include (i) the removal of the DC and conjugate image terms, which are features of the holographic recording process,...

Automatic 3D Reconstruction for Symmetric Shapes

Generic 3D reconstruction from a single image is a difficult problem. A lot of data loss occurs in the projection. A domain based approach to reconstruction where we solve a smaller set of problems for a particular use case lead to greater returns. The project provides a way to automatically generate full 3-D renditions of actual symmetric images that have some prior information provided in the...
