Facial thermography device using a plurality of thermal imaging cameras

An infrared thermal imaging diagnostic device is a device that displays minute changes in body heat occurring in the human body as a color image using infrared rays.

In general, the infrared thermal imaging diagnostic device can objectively and accurately diagnose the presence or absence of pain syndrome, and is a useful test device that can visually confirm the progress of treatment and whether or not it is fully cured by comparing the progress before and after early diagnosis of various diseases. It is currently preferred by domestic and foreign western/oriental clinical medical staff, and the demand for it is rapidly increasing.

In recent years, infrared thermal imaging devices have been able to take pictures without contact with the body, and can quantitatively measure minute changes in body heat in all diseased parts of the human body. However, infrared cameras are precision and high-difficulty technology-integrated fields that are used for the US military, and are quite expensive, and there are no domestic manufacturers of infrared cameras. Imported and supplied for medical use.

However, since the conventional apparatus for measuring body heat takes a thermal image of the front of the subject's face using only one thermal imaging camera, it is difficult to obtain information on the temperature distribution on the side of the face, and a rather complicated image processing algorithm Since this is applied, there is a disadvantage in that it takes a relatively long time to process information.

As described above, when the photographing unit 260 rotates the first thermal imaging camera 111 by the associated rotating unit, the second thermal imaging camera 112 is also rotated together, so that the thermal imaging cameras can be set more easily.

The description of the presented embodiments is provided to enable any person skilled in the art to use or practice the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not to be limited to the embodiments presented herein, but is to be construed in the widest scope consistent with the principles and novel features presented herein.

100: Facial body heat imaging device using a plurality of thermal imaging cameras
110: shooting unit
111: first thermal imaging camera
112: second thermal imaging camera
120: image providing unit
121: display unit
