Object stereoscopic image data acquisition system

The invention relates to an object stereoscopic image data obtaining system, in particular to a system for scanning an outer peripheral surface of an object and scanning a bottom model of the object to obtain an overall stereoscopic image of the object.

The human body structure is quite precise and complicated. Because the human foot needs to carry the weight and the force of the ground impact during the activity, if the joints or bones of the foot are defective due to the lesion or posture, it will cause great damage to human health and quality of life. influences. Therefore, with the rise of health awareness, various techniques for customizing insoles or correcting shoes have been developed, and the insole is customized by obtaining the user's foot model to reduce the impact on the foot due to poor posture during the activity. .

In the prior art, at present, most of the plaster is attached to the sole of the user to obtain the contour of the sole, and the insole is manufactured according to the obtained plaster model. However, the gypsum film can only obtain the contour of the sole of the foot and takes a long time. In addition, when using the gypsum to take the mold, the user needs to be prone to let the sole of the foot hang, and the model obtained in this posture can only present the user to the foot. When the force is applied, the state of the contour of the sole cannot accurately reflect the force state of the contour of the sole of the foot when the user is stressed on the foot (for example, walking or standing), so most of the insoles manufactured by such models cannot cooperate with the user. Or the condition of the foot when standing, so there is room for improvement. Moreover, since the plaster can only obtain the plantar model, in the manufacture of the insole or the corrective shoe, the user is required to continuously try on the sample to finely adjust the insole or the corrective shoe of the user who is more suitable for walking. The manufacturing steps after the modulo change become cumbersome and are not convenient for the user and the manufacturer.

Therefore, it is necessary to provide a model that can simultaneously obtain the actual contour of the foot and other parts of the foot when the foot is stressed, and provide a more accurate basis for the subsequent manufacturing process to solve the problems of the prior art.

The main object of the present invention is to provide a method for scanning the outer peripheral surface of an object and scanning the appearance model of the bottom surface of the object to obtain an overall stereoscopic image of the object.
