Body surface scanning data are mostly stored in point-cloud format currently. This paper describes a novel body surface profile information recording method for the human body, which called shape map format. It adopts novel surface morphological information processing methodology, which is able to retrieve and store both the two-dimensional (2D) and three-dimensional (3D) information of the waist to hip section. Compared to the point-cloud data format, its presentation is more intuitive; its resolution rate is higher; its sampled point distribution is better for surface modeling and its size is much smaller, which is only about 12% of the original form. We have designed two data processing modules in Matlab that convert the body surface scanning data from point-cloud format to shape map format and conversely. Its performance have been evaluated using the 3D scanning data of the waist to hip human body section sampled using a [TC]2 3D scanner.
