Calculation Method for Phenotypic Traits Based on the 3D Reconstruction of Maize Canopies

Abstract: A reasonable plant type is an essential factor for improving canopy structure, ensuring a reasonable expansion of the leaf area index and obtaining a high-quality spatial distribution of light. It is of great significance in promoting effective selection of the ecological breeding index and production practices for maize. In this study, a method for calculating the phenotypic traits of the maize canopy in three-dimensional (3D) space was proposed, focusing on the problems existing in traditional measurement me… Show more

“…(2022) collected 3D point cloud data of maize across extensive fields employing terrestrial laser scanning and obtained the stem diameters by applying elliptical fitting techniques, achieving an R ² in excess of 0.8. Ma et al. (2019) employed a handheld lidar to obtain the diameter of potted maize stems, achieving an R ² of 0.89.…”

“…Miao et al (2022) collected 3D point cloud data of maize across extensive fields employing terrestrial laser scanning and obtained the stem diameters by applying elliptical fitting techniques, achieving an R² in excess of 0.8. Ma et al (2019) employed a handheld lidar to obtain the diameter of potted maize stems, achieving an R² of 0.89. Nonetheless, given that lidar technology utilizes laser beams to gauge object surface distances, its utility is primarily confined to the acquisition of 3D point cloud data of maize plants, with an inherent limitation in gathering chromatic information.…”

“…In this study, the image-based 3D reconstruction method with simple operations was used, where the RGB camera, which was cheap, could be integrated onto the self-established phenotype platform, thereby providing an effective solution to the extraction of crop phenotypes. In addition, studies on 3D reconstruction of maize have been more focused on the ears and grains stage (Ma et al, 2019;Wang et al, 2019;Zhu et al, 2020;Zhang et al, 2022a), while less attention has been paid to 3D reconstruction of seedlings.…”

“…Our method has four advantages. First of all, the 3D mesh model of the plant obtained by ZGScan 717 has higher precision and richer details compared to those reconstructed by the SFM method [24], time-of-flight (ToF) method [22], binocular stereo vision method [27], LIDAR method [34], and FastSCAN hand-held scanner [35]. The 3D mesh model is reconstructed in real-time during data scanning and can be output directly, thus saving data processing time for 3D reconstruction in most contemporary research.…”
