| Research Abstract |
A 3D shape measurement system employing a digital camera and multiple mirrors was developed, and the 3D shape of cabbage seedlings was successfully reconstructed from 2D images using the volume intersection method. The seedlings had thin leaves, which required high measurement precision. The calibration method using a cubic calibration guide proposed in this study was found to be effective and the R hard points seemed to be effective for volume intersection for obtaining the 3D shape of the leaves.
