O3D The breaking down of the motion. The corporeal dynamism and the morphometric structures by 3D laser scanner survey

The movement, as motion, action and gesture, is the expression of the will of mind and of the raw manifestations of unconscious. As the stream of consciousness carries the seeds of what will happen later, the motion of the body is an endless process where every gesture rises and develops itself from the previous; it already leads the semblance of following actions, in a continuous cycle. The 3D survey representation of the corporeal dynamism is indissoluble and indistinct magma of fragmented and seemingly incomprehensible corporal outlines. So far studying this confused collected data turns out to be a complicated process. It is necessary to study a strategy of research to fragment the continuity of the motion in a series of isolated sequences. A matching representative methodology must produce clear results. To break down the complexity of the motion and to understand its mechanisms, the study of the morphometry of the figure is required as starting point to understand the fragmentation before observing the whole body, otherwise the difficulty in recognizing the morphometric disintegration would be excessive. The research started from the survey of the human figure in static positions by means of laser scanner based on the time of flight technology. During the acquisition process the observation of the way in which the data was collecting on the screen of the computer, allowed the researcher to have the necessary experience to comprehend the subsequent survey procedure to acquire body in a dynamic condition. In a static condition the scanning of human figure is made of singles corporal outlines. They are added up in order to create the complete survey in the three dimensions of the space. In the dynamic condition the survey shows mixed corporeal outlines: the scan procedure doesn’t involve a single person but people. The outline of each person is not to be considered added up, but mixed up. This is the reason why, in order to create a date base about the corporal dynamism, the research has been articulated by topics analysed by means of increasing scales: starting from the motion of a single figure, for instance, in the case of steps. Then interactions between two people and groups of people (corporeal flows in spaces like an aisle) have been studied. The confusion that initially characterized the data, once decoded, it becomes a matrix of knowledge to be analysed through several levels of investigation. By means of the recognizing of the position of the corporeal articulations in a three-dimensional measurable space, like the point clouds, it is possible to point out the different corporeal outlines of each subject and then to identify the 3D model taking place in space and time, to rebuild the real dynamic process and in the case of interaction with other subjects, the proxemics development of their relation.
