DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a three-dimensional measurement technique, and more particularly to a variable-focus three-dimensional imaging device. °[Previous technology] With the development of three-dimensional digital brooming technology and the development of reverse-vehicle technology, the three-dimensional digital scanning cat has gradually entered the industry, for the design process - ring, the product section , model (four) hair, etc., Yiyi does not have a close combination with three-dimensional digital scanning. However, in recent years, the digital three-dimensional scanning technology has been presented in different fields and four-inch color into various fields, such as the digital preservation of culture and art (the ancient bronze statue of Italy, the digital image of ancient Chinese Buddha statues) Modeling and preservation of three-dimensional dynamics, three-dimensional dynamic model construction (movies such as Luo Jiyuan, space warriors), dental research in medical research, bone scanning, and even archaeological research applied to anthropology, etc. A digital 3D scanner broom and construction model. In addition, in response to the rapid increase in broadband and computer speed, the digital 3D scanning technology has been expanded to include e-commerce, product port presentations, video games, etc., and then the importance of digital 3D scanning technology is displayed. Sex. U.S. Patent No. 6,529,280 discloses a three-dimensional measuring device for measuring a two-dimensional coordinate of a test object and a measuring method thereof, wherein the three-dimensional/shell J-coating system adopts a single-lens zoom control mode with visible light. The strip scans the object to be tested from top to bottom, and then passes through the plurality of images S that receive the reflected scanning band to determine the phase value of each object point, and the triangle geometry 5 18977 1297803 Each phase value is converted into a complex height information to calculate a three-dimensional coordinate of the object to be tested. The three-digit coordinates can then be output to a drawing software such as CAD to construct a three-dimensional image. The disc "quasi" and patent A cases adopt a single fixed-focus lens design, and the scanning range "the resolution is depreciated, and it is impossible to provide adjustment according to the volume of the object to be tested or the measurement of the demand." Without scanning range and resolution The elastic adjustment function and the single-focus lens design are also easy to cause the image dead angle to affect the amount) Ά In addition, since the image capturing speed depends on the scanning speed, it is time consuming and only suitable for active measurement. Does not meet the economic benefits of use. t. In the case of China’s invention patent No. 576729, it is proposed to adopt a multi-mirror group. A two-dimensional contour scanning device like a sensing element, however, because the same focus lens design is adopted, the scanning range and resolution are also fixed, and can only be applied to the wheel of the special object (teeth), which cannot be applied to The larger volume of the object to be treated also has no elastic adjustment function of the scanning range. Since the 7th century, there have been several companies and scientists who have been working on three-dimensional, and the world’s most advanced three-dimensional stereo camera has still reported many defects and ills, such as It is a problem such as distortion of the image speed of the camera. Although some products have been able to break through one of them, for example, using a laser scanner to take a three-dimensional image, although it is a good month, it is a slap in the face, and it takes at least a jk to take a portrait. Moreover, the clock shot has a lot of harm to the human body, and it is not good for the second application. Another example is a laser three-dimensional digital camera, although

Color bar code image to supply other devices for use in the three-dimensional coordinate data of the object to be tested' or even provide, for example, C too private, like. In other embodiments, the varifocal three-dimensional image capturing device may also include an operation-like "image _step _ the color bar code light projecting unit 2 and each of the early elements 3 for capturing The color bar code image operation 18977 13 1297803 The three-dimensional information of the object to be tested. The varifocal three-dimensional image capturing device of the present invention may also include an operation control unit, and the varifocal three-dimensional image capturing device provided by the foregoing invention is integrated only by the foregoing implementation, and the f color bar code light projecting unit is integrated. a plurality of image capturing units and a focal length adjusting unit in the body and through the focus adjusting unit can synchronously adjust the zoom and focus of the color bar light projecting unit and each of the image capturing units, and thus have elastic adjustment and image capturing The range and resolution functions, and the design of the operation is easy to use and ensures stable image quality. In addition, the use of the complex (four) (four) unit to capture the color bar code image design, not only can reduce the image dead angle, but also because the image capture speed depends on its shutter time, compared to the scanning method of the prior art can greatly shorten the image The time and the complex are applicable to both active and passive measurement applications, and the prior art is present in the prior art. rWi «Sn η ^ ^ The above embodiments are merely illustrative of the principles of the invention and are not intended to limit the invention.
