In this paper, we propose a novel method for 3D human joint estimation using part seg-mentation, and introduce an application for size measurement based on the obtained joints. A human segmentation dataset is first prepared as training set for the advanced neu-ral network architecture. Different human parts yielded from the neural network are uti-lized to extract human joints. In the proposed method, the joints are categorized into the active joints and inert joints. In the extraction process of the active joints, the mathe-matical analysis method is adopted to calculate the joint positions. The geometric features of different human segments are further used to extract the inert joints. Moreover, we test on the dataset to compare its performance with our previous method based on geometrical features. The results show the average error of the joints is less than 4.2 cm, which is sig-nificantly improved from 5.8 cm demonstrated in our previous research. We also investi-gate the human size measurement. The distance between the joints is used to calculate the length, and the ellipse fitting method based on multi-frame point cloud is adapted to calculate the human girths. Compared with the manual measurement data, the size error is less than 4.1 cm.(c) 2022 Elsevier Inc. All rights reserved.
