High-fidelity 3D plants model reconstructed based on color structured light

In order to construct the high-precision and high-fidelity 3D plants model quickly and economically, this study present a new approach to combing the color structured light with silhouette-based method to repair the model´s depth information. First, project the coded color structured light which is coded using spatial code method on the surface of the plants. And photograph the plants using two non-contract cameras from different angles. Second, we need to extract the center of the stripes and decode the structured light base on color space conversion. Then, gain the feature points using the method of color stripes matching base on epipolar constraint. Finally, calibration the camera and computation of feature points´ coordinates. Reconstruct the 3D model of plants base on the feature points. Experimental results show that the method could repair the 3D model´s depth information effectively.
