Description
Technical Field
The invention relates to the fields of three-dimensional foot shape scanning and computer processing, in particular to an accurate station position automatic monitoring and prompting system and method of a three-dimensional foot shape scanner.
Background
Nowadays, the internet in China is rapidly developing online in the consumer industry. The technology which is essential and indispensable as the link of purchasing shoes and/or measuring feet on line through three-dimensional foot shape scanning is greatly improved, and the precision is continuously improved and the cost is reduced.
In the actual measurement process, the process of acquiring the human body data has particularity and complexity. In order to enable the acquired human body data to be well applied in the future (ensure the continuity of the data), on one hand, the accuracy of single sample data is ensured; on the other hand, the consistency of the group data is also ensured, namely the sample data in the data set is obtained under the same condition of the same environment of the sample. It is possible for such a data set to be sorted and analyzed to obtain a certain regularity and mathematical model.
Currently, the improvement of the technology and the precision of the instrument can only ensure that the three-dimensional shape of an object put into the equipment is restored as truly as possible, namely the accuracy of single sample data is ensured. However, the human body is a complex flexible body composed of bones, muscles, and the like. The shape of the body in real space at a certain time is greatly related to environmental factors such as external or weight pressure, the degree of contraction of muscles, and the temperature and humidity to which the body is exposed. These influencing factors cause complex and inaccurate predictable deformations of the body shape over a range.
Therefore, if the consistency of the posture of the human body and the stress and force applying states of the scanned organ during scanning, that is, the deformation of the body is inconsistent, even if the device can accurately acquire the three-dimensional shape of the object, the intrinsic regularity and value of the data of the whole sample set are greatly reduced.
Specifically, the shape of the human foot is greatly affected by factors such as the posture of the body, the load, and the direction of the central axis of the foot during scanning. Generally, for a user, the body is required to be in a standing posture, feet are as wide as shoulders, the feet are parallel to a central axis, the head and the chest are raised, the hands naturally droop, and the body in front is kept relaxed as much as possible by visual observation. In such a body posture, the weight of the person can be uniformly applied to the left and right feet and uniformly transmitted to the load-bearing plane through the sole, so that the deformation of the feet is also uniform. Moreover, in the practical application of the three-dimensional foot type scanner, the user can easily adjust the body to the posture relative to other postures, and the understanding error is less, so that the consistency of the stress and the force application of the feet of different samples is ensured.
In the existing three-dimensional foot type scanner, the device does not have any constraint requirement on the posture of a human body during scanning in the using process according to the principles of laser, white light and the like, so that oral explanation and reminding are required for an operator, the complexity of operation is increased, and the automatic measuring degree of the device is reduced.
