Problems solved by technology

In the third dimension, it can be found that the patient and the camera are completely still during the recording of successive images, (which) leads to difficulties in clinical operation, especially when the photoelectric components of the camera are moving
As the only 3D system that has been proposed for decades, due to lack of innovation, it is inaccurate, time-consuming and complex to process, and very expensive to implement
All of the security solutions mentioned above, as well as other simple solutions, cannot meet the requirements of dental photogrammetry, which requires fast implementation, high accuracy and measurement of true color and depth of field on a relatively large surface

Abstract

The three dimensional measuring device used in the dental field and aimed at measuring in the absence of projection of active or structured light, includes an image-capturing device and data-processor for images. The image-capturing device is capable of simultaneously, or almost simultaneously, capturing at least two images, one of which is totally or partially included in the other one. The included image describes a narrower field than that of the other one, and has a higher accuracy than that of the other one.

Description

technical field [0001] The invention relates to a new safety measuring device, which is realized by non-contact, high-precision, wide-field unstructured active light projection and light-color effect projection, and is especially suitable for the field of dentistry. [0002] The invention ensures the integrity of the acquired human body structure image and has the accuracy within 1 micron. It is suitable for obtaining pictures of the oral cavity in the medical and dental fields, and is also suitable as a diagnostic aid. [0003] It includes: [0004] 1. A small three-dimensional reading system that does not use active light projection or structured light projection to measure the size of components, including: [0005] a) one or more CCD-type or CMOS-type electronic sensors and associated optical systems, [0006] b) Finally, a LED or OLED illumination source with one or several wavelengths, diagnosing conditions of the tooth or gum surface, [0007] c) One or more acceler...
