本發明係有關於一種具姿態感應功能之攝影裝置、口腔攝影方法及口腔攝影器，特別是指藉由姿態感應功能使拍攝影像能在顯示單元上以最佳觀測方位輸出之攝影裝置，以及進一步能將局部口腔影像疊合在全齒口腔畫面相對應位置輸出，作為指示口腔拍攝位置之口腔攝影器。The invention relates to a photographing device with an attitude sensing function, an oral photography method and an oral camera, in particular to a photographing device capable of outputting a photographed image on an image display unit with an optimal observation orientation by an attitude sensing function, and further The partial oral image can be superimposed on the corresponding position of the full-tooth oral image as an oral camera indicating the position of the oral cavity.
一般內視鏡醫療、口腔攝影，或者是地質探勘、災後救援時，當使用攝影單元伸入拍攝時，攝影單元為撓性裝置，因此影像輸出的上方與物體的實際上並不一致。另外一般手持式攝影機拍攝時，會因攝影機歪斜拍攝輸出影像會呈現傾斜，例如本案第三A圖所呈現之拍攝影像(B)，甚至呈現上下顛倒的影像，例如本案第三B圖所呈現之拍攝影像(B)。觀察者觀看攝影機的影像輸出時，為了瞭解或是觀看影像的意義或是內容時，常需要將螢幕旋轉一角度(螢幕小時)，或甚至是觀察者旋轉一角度(螢幕大時)，以便得到較佳的觀測影像，不利於觀察者觀察。In general endoscopic medical treatment, oral photography, or geological exploration, post-disaster rescue, when the camera unit is used for projection, the camera unit is a flexible device, so the upper part of the image output is not consistent with the object. In addition, when shooting with a hand-held camera, the output image will be tilted due to the camera's skew, such as the captured image (B) presented in Figure 3A of the case, or even an upside-down image, such as the third B picture in this case. Shoot the image (B). When the observer views the video output of the camera, in order to understand or view the meaning or content of the image, it is often necessary to rotate the screen by an angle (screen hour), or even the observer rotates an angle (the screen is large) to get The better observation image is not conducive to observer observation.
另外，口腔醫療或口腔健康檢查時，為了便於觀察及方便對病患講解說明，因此有口腔攝影機的使用，例如中華民國新型專利公告第M308052號揭露「口腔攝影裝置」；中華民國新型專利公告第M240999號揭露「數位無線傳輸口腔攝影機裝置」。In addition, for oral medical or oral health examinations, for the convenience of observation and convenienceThe patient explained the explanation, so there is the use of an oral camera. For example, the Republic of China New Patent Bulletin No. M308052 discloses "oral photography device"; the Republic of China New Patent Publication No. M240999 discloses "digital wireless transmission oral camera device".
前案的口腔攝影裝置雖然能夠拍攝，並在螢幕上顯示口腔影像，但是仍有以下缺失待克服：其僅能在螢幕上顯示攝影器所拍攝之影像，無法提示所拍攝之位置，醫生需對病人講解，有時容易造成誤解，而產生醫療糾紛。Although the oral photography device of the previous case can shoot and display the oral image on the screen, the following defects are still to be overcome:It can only display the image captured by the camera on the screen, and can not prompt the location of the shooting. The doctor needs to explain the patient, sometimes it is easy to cause misunderstanding, and a medical dispute arises.
基於攝影裝置及口腔攝影器仍有上述缺失待改善，本發明預期提出一種能夠不隨攝影單元翻轉角度變化，而能將拍攝影像維持在水平顯示位置的攝影裝置，達到內視鏡醫療、地質探勘、或者是災後救援時最佳的輸出影像以供觀測或分析，並進一步提出一種能夠提示口腔影像拍攝位置之口腔攝影器。Based on the photographic device and the oral camera, the above-mentioned defects are still to be improved, and the present invention contemplates a photographic device capable of maintaining the captured image at the horizontal display position without changing the angle of the photographic unit, and achieving endoscopic medical and geological exploration.
