Hand intelligent 3D information acquisition and measurement device

Abstract

The invention provides a hand intelligent 3D information acquisition and measurement device and method. The acquisition and measurement device comprises an image acquisition device and a bearing plate, and the image acquisition device and the bearing plate are oppositely arranged; the bearing plate is used for bearing hands; the image acquisition device is arranged on the rotating device, and an included angle gamma is formed between the optical axis of the image acquisition device and the rotating plane. A mode of forming an included angle between a camera optical axis and a rotating plane isproposed for the first time to simultaneously improve the synthesis speed and synthesis precision of the hand 3D model. By optimizing the positions of pictures acquired by the camera, it is guaranteed that the 3D synthesis speed and synthesis precision of the hand can be improved at the same time; and when the position is optimized, angle measurement and target size measurement are not needed, sothat the applicability is higher.

Description

technical field [0001] The invention relates to the technical field of hand shape measurement, in particular to the technical field of 3D shape measurement. Background technique [0002] When performing 3D hand measurement, one-dimensional and two-dimensional measurement methods are usually used, such as using measuring tools to measure the length, width, and height of the hand. The data obtained in this way can be used to select gloves of appropriate size for users. However, such gloves are designed by the factory assembly line according to the size regulations, and the industry has not yet carried out further size segmentation. In order to give users a better wearing experience, gloves of different sizes and shapes should be customized for each user. To achieve this, 3D acquisition and measurement of the human hand is necessary. But for customizing thousands of different customers, the requirements for acquisition speed and accuracy are very high, otherwise it will bring...

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
