Field estimation of maize plant height at jointing stage using an RGB-D camera
文献摘要：
Plant height can be used for assessing plant vigor and predicting biomass and yield.Manual measure-ment of plant height is time-consuming and labor-intensive.We describe a method for measuring maize plant height using an RGB-D camera that captures a color image and depth information of plants under field conditions.The color image was first processed to locate its central area using the S component in HSV color space and the Density-Based Spatial Clustering of Applications with Noise algorithm.Testing showed that the central areas of plants could be accurately located.The point cloud data were then clus-tered and the plant was extracted based on the located central area.The point cloud data were further processed to generate skeletons,whose end points were detected and used to extract the highest points of the central leaves.Finally,the height differences between the ground and the highest points of the cen-tral leaves were calculated to determine plant heights.The coefficients of determination for plant heights manually measured and estimated by the proposed approach were all greater than 0.95.The method can effectively extract the plant from overlapping leaves and estimate its plant height.The proposed method may facilitate maize height measurement and monitoring under field conditions.
