4DHumanOutfit: A multi-subject 4D dataset of human motion sequences in varying outfits exhibiting large displacements

Protocols for High-Quality Indoor and Outdoor Scanning of Clothed People

“…The planning requires defining clear goals and motivation to carry out the project, specifying the list of scanning equipment which will be used or ordered, assigning the roles to the core team members, and defining a timeline with a sequence of steps to carry out the data(set) acquisition protocol. Depending on the application, it is recommended to hire actors for the acquisition (scanning) stage [18]. The actors can consistently repeat defined sequences of actions without significant oscillations.…”

“…For 3D body scanning, the person usually takes one of the standard poses (T-pose, A-pose, I-pose, or sitting positions) [5]. Using the standard poses simplifies the postprocessing stage, body measurement extraction algorithms, and separating body from clothing [18]. For 4D scanning, the actor should be precisely instructed how to carry out the motion sequence, which includes the initial body pose, the speed and the sequence of movements (which affects the overall sequence duration), and the final pose.…”

“…Studies have even shown that the scanning technology of the human body has become comparable in accuracy to the expert measurers [2,3,4], which are still the golden standard [5]. These remarkable technological improvements and the availability of the high-quality scanners to smaller laboratories have resulted in several, publicly available, free, and high-quality 3D and 4D datasets of human bodies in tight or minimal clothing [6,7,8,9,10,11] and in everyday clothing [12,13,14,15,16,17,18]. The publicly available datasets are particularly useful for the research community, fostering advancements in anthropometry, textile research, computer vision, fitness, and medicine [1].…”

“…Nevertheless, the acquisition of high-quality human scanning datasets is still time-consuming, complicated, and potentially costly due to mandatory compliance with the data regulations, the need to hire actors which can consistently repeat certain sequences of motions and engineers which can postprocess the data, while also managing the entire process over extended periods of time [18]. To simplify scanning protocols, the standards for human body measurement have already been established [5,19].…”

“…There are several surveys, reviews, and books that overview the scanning protocols and recommend the best practices for particular applications [1,20,21,22,23]. Specific to 3D and 4D scanning of people in loose clothing, there are a few successful methods which also discuss the protocols but also the limitations of the technology and the postprocessing algorithms [12,13,17,18].…”
