Piikkio2023 lettuce 3D pointcloud dataset for fresh weight estimation

The dataset is a supplementary material for the paper "A method for phenotyping lettuce volume and structure from 3D images" (https://doi.org/10.1186/s13007-025-01347-y) and includes 402 3D point clouds of lettuce with reference fresh weight values ranging from 62.3 to 276.5 g. Additional 3D images of these plants recorded throughout their growth were made, though they do not have reference values.
