Способ бесконтактных измерений размерных параметров фигуры по проекционным изображениям на основе модели исс
Аннотация
В статье описывается способ дистанционного измерения антропометрических параметров фигуры человека по проекционным изображениям. Данный способ измерения основывается на комбинировании двух методов антропометрических вычислений — прямых измерений координат антропометрических точек поверхности фигуры по ее проекционным снимкам и аналитического описания размерных параметров фигуры. Отличительной чертой предлагаемого способа определения трехмерных координат поверхности фигуры по проекционным снимкам является использование дополнительных измерителей координат точек, разработанных на основе модели имитатора световых меток.

The article describes the method of remote measurement of anthropometric parameters of a human figure from projected images. A new method for remote measurement of the dimensional parameters of a human figure from projected images with use of projected light marks is proposed. At core of the developing technology of three-dimensional scanning of objects of complex spatial form is the solution to the problem of obtaining information about the coordinates of any point of the examining object surface and their reciprocal position relative to each other on the figure projection images based on the model of LSI (light structure imitators). A distinctive feature of the proposed technology for determining the three-dimensional coordinates of the surface of a figure from projected images is the use of additional measuring points for the coordinates of the points on the surface of the figure, developed on the basis of the LSI model, in order to improve the accuracy of calculating the dimensional parameters of the figure. The additional measurer consists of a light pointer projecting light marks onto the surface of a figure or equivalent to them marks placed on the surface of the measuring object. This method of measurement is based on the combination of two methods of anthropometric calculations — direct measurements of the coordinates of the figure surface anthropometric points from its projection images and an analytical description of the dimensional parameters of the figure. Herewith, the spatial coordinates of the light marks are determined by the method of optical triangulation. The triangulation method for measuring distances realized in a triangulation measurer is based on calculating the required distance through the ratio of the triangle formed by the optical axis of the camera, by the design line of the light label and by the baseline of the measurement — the distance between the photo detector axis and the axis of the light pointer.The measured coordinates of the surface points by the method of optical triangulation are used to calculate the anthropometric parameters of the figure, including the girth and longish geometric characteristics of the figure. On the basis of the proposed method of contactless measurements of anthropometric parameters of a human figure from a projection image using a simulator of light marks and the method of optical triangulation, the 3D Body measuring system was developed. The measurement error of the 3D scanning system is not more than 0.3 cm, which corresponds to the standard requirements in the garment industry. Measurement speed is up to 30 sec. As a result, it was possible to increase the efficiency of anthropometric research conducting and clothes designing.
