本發明是有關於一種量測裝置，特別是指一種用以量測釘體尺寸的量測裝置。The invention relates to a measuring device, in particular to a measuring device for measuring the size of a nail body.
由於釘體之尺寸規格相當多，一般使用者需要使用釘體時，通常很難確定手邊之釘體的長度與直徑等尺寸，所以經常會帶著釘體去找零售商或小型釘廠，這些零售商或小型釘廠為了確認釘體的確實尺寸規格，通常會取用尺規量具進行量測，相當的麻煩。Since the size and size of the nail body are quite large, when the user needs to use the nail body, it is often difficult to determine the length and diameter of the nail body at hand, so the nail body is often taken to the retailer or the small nail factory. In order to confirm the exact size of the nail body, the retailer or the small nail factory usually takes the gauge gauge for measurement, which is quite troublesome.
有鑑於此，有業者試圖將釘體放置在固定高度的拍攝架上，先取得手機或相機鏡頭視野的實際尺寸，再換算成每一個圖素的尺寸。然後再將釘體放入此拍攝架下，用同樣的條件去拍攝，然後用釘體佔用的圖素數量來換算成釘體的實際尺寸。但因為一般相機與手機的鏡頭都具有廣角效果設計，鏡頭邊緣區域的影像容易出現變形失真情況，且拍攝時的對焦距離與鏡頭變焦情況，都會影響所拍攝影像大小，必須透過複雜的影像處理才能得到準確地尺寸資料。In view of this, some operators try to place the nail body on a fixed height shooting frame, first obtain the actual size of the field of view of the mobile phone or the camera lens, and then convert it into the size of each pixel. Then put the nail body under the shooting frame, use the same conditions to shoot, and then use the number of pixels occupied by the nail body to convert to the actual size of the nail body. However, because the lens of the camera and the mobile phone have a wide-angle effect design, the image in the edge area of the lens is prone to distortion and distortion, and the focus distance and the zoom of the lens will affect the size of the captured image, and must be processed through complex image processing. Get accurate size information.
