A foot intelligent 3D information collection and measurement device

Abstract

The invention provides foot intelligent 3D information acquisition and measurement equipment which comprises an image acquisition device and a background plate, and is characterized in that the imageacquisition device and the background plate are oppositely arranged and synchronously rotate; the background plate and the image acquisition device are kept oppositely arranged in the rotating process, so that the background plate becomes a background pattern of an image acquired by the image acquisition device during acquisition; and the image acquisition device and the background plate rotate around feet. The mode that the background plate rotates along with a camera is added for the first time to improve the synthesis speed and the synthesis precision of a foot 3D model at the same time. Byoptimizing the size of the background plate, while the rotating burden is reduced, it is guaranteed that the foot 3D synthesis speed and the foot 3D synthesis precision can be improved at the same time.

Description

technical field [0001] The invention relates to the technical field of shape measurement, in particular to the technical field of 3D shape measurement. Background technique [0002] When performing 3D measurement of feet, one-dimensional and two-dimensional measurement methods are usually used, such as measuring the length, width, and height of the foot with measuring tools. The data obtained in this way can be used to select shoes of the appropriate size for the user. However, such shoes are designed according to the size regulations of the factory assembly line. Even users who wear the same size shoes have different foot sizes. However, the industry is not currently subdivided in this way. [0003] In order to give users a better wearing experience, shoes of different sizes and shapes should be customized for each user. To achieve this, 3D acquisition and measurement of the human foot is necessary. [0004] For foot 3D information collection, currently commonly used met...

Problems solved by technology

However, in practical applications, it is found that unless there is an accurate angle measurement device, the user is not sensitive to the angle, and it is difficult to determine the angle accurately; the size of the target object is difficult to accurately determine, especially in some applications where the target object needs to be replaced frequently. A lot of extra work is required, and professional equipment is required to accurately measure irregular targets

Measurement errors lead to camera position setting errors, which will affect the speed and effect of acquisition and synthesis; the accuracy and speed need to be further improved
