Description

Multi-lens oral cavity observation system

Technical Field

The invention relates to an oral cavity observation system, in particular to a multi-lens oral cavity observation system for shooting faces and oral cavities.

Background

Along with the increasing importance of people on oral health, various oral cavity observation devices are brought forward, the state in the oral cavity is shot through the camera system and is displayed on the display in real time, so that the clinical examination of doctors and the daily oral health monitoring of people are facilitated.

Because the oral cavity space is small, in order to better observe the condition in the oral cavity, the lens of the existing oral cavity observation equipment is generally a near-focus lens so as to be beneficial to small-space near-focus shooting in the oral cavity.

However, with the popularization of oral observation and monitoring at present, especially when the oral cavity of people with large sample size is generally checked, for example, in kindergarten, primary school, and the like, pictures or videos shot by the oral observation instrument or the oral endoscope in the prior art are pictures or videos inside the oral cavity, and meanwhile, the pictures or videos processed by a large number of almost similar pictures and videos are easy to be confused and indistinct from the pictures or videos of other people. Therefore, if the facial morphology of the detected person can be shot before the internal observation of the oral cavity is carried out, the confusion of the collected oral cavity data can be well avoided. However, the existing oral cavity observation instrument or oral cavity endoscope often cannot shoot objects in a long distance due to the limitation of the focal length, such as shooting images of human faces, so that it is difficult to clearly shoot the facial features of people subjected to oral cavity examination while shooting clear teeth, and therefore, the existing oral cavity observation equipment needs to be improved, so that an oral cavity observation system, or called oral cavity observation instrument or oral cavity endoscope, can clearly shoot the conditions of teeth and oral cavity, can clearly shoot head images, is convenient to record, and can store data.

Disclosure of Invention

The multi-lens oral cavity observation system aims to solve the problem that the existing oral cavity observation system cannot simultaneously take near-focus shooting and far-focus shooting into consideration, and the multi-lens oral cavity observation system can switch between the near-focus lens and the far-focus lens through the multi-lens design, so that the oral cavity observation system can shoot at a long distance and meet the requirements of short-distance shooting and observation in the oral cavity.

The multi-lens oral cavity observation system of the invention is characterized in that: the multi-lens oral cavity observation system 100 comprises a shell 1, a power supply system 2, an illumination system 3, an observation system 4, a circuit system 5 and a switch 6;

A. the observation system 4 is a camera system 41, and the camera system 41 comprises a data processing system 41-1 and at least 2 cameras 41-2;

B. the lighting system 3, the observation system 4, the circuit system 5 and the power supply system 2 are installed in the shell 1, and the switch 6 is installed on the shell 1; the lighting system 3, the viewing system 4, the power supply system 2 and the switch 6 are connected together by the circuitry 5;

C. different cameras 41-2 can take pictures or images of different objects.

Further, the camera 41-2 at least comprises 1 near-focus lens 41-21. The close-focus lenses 41-21 can well meet the requirements of small space, close-range observation and shooting in the oral cavity.

The multi-lens oral cavity observation system combines the near-focus lens 41-21 and the common far-focus lens through the special design of at least 2 cameras 41-2, can be switched between the far-focus lens and the near-focus lens, can clearly shoot the facial profile morphology by selecting the far-focus lens when the facial morphology of a person needs to be shot according to the needs, and can clearly shoot each part in the lower oral cavity, particularly teeth and peripheral tissues thereof at a short distance by switching to the near-focus lens for working when the internal state of the oral cavity needs to be shot.

The illumination system 3 is arranged in the vicinity of the in-focus lenses 41-21. The illumination system 3 is arranged directly in the vicinity of the said in-focus lenses 41-21, in particular around the lenses; direct illumination may be provided to the near-focus extremities 41-21, particularly for auxiliary illumination deep in the mouth.

The illumination system 3 is an LED light source 31. Compared with the common lighting light source, the LED light source has the characteristics of small volume, high luminous efficiency, strong light source directivity and the like, and particularly has the incomparable advantages of the common light source in the aspect of safety. Firstly, the LED light source is supplied with low-voltage direct current, and the supply voltage is only 6 to 24V; secondly, mercury is not added in the LED light source, so that poisoning and other injuries to a human body cannot be caused; in addition, more importantly, the LED light source is a cold light source, can not generate heat seriously in the working process, can be safely touched, and can not cause accidental high-temperature scald to human bodies. Therefore, the LED light source has safety while meeting the lighting requirement, and the LED light source can directly enter the oral cavity of a human body.
