以下將參照相關圖式，說明依本發明較佳實施例之一種電子鎖裝置，其中相同的元件將以相同的參照符號加以說明。DETAILED DESCRIPTION OF THE INVENTION An electronic lock device in accordance with a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein like reference numerals will be used.
圖1為本發明較佳實施例之一種電子鎖裝置1的方塊示意圖。電子鎖裝置1包含一取像單元11、一分析單元12、一電磁鎖13以及一鎖具驅動單元14。電子鎖裝置1可例如應用於門鎖、或電子裝置的啟動鎖，電子裝置例如為平板電腦、手機等等。
1 is a block diagram of an electronic lock device 1 in accordance with a preferred embodiment of the present invention. The electronic lock device 1 includes an image taking unit 11, an analyzing unit 12, an electromagnetic lock 13, and a lock driving unit 14. The electronic lock device 1 can be applied, for example, to a door lock, or a start lock of an electronic device such as a tablet computer, a mobile phone or the like.
取像單元11係可取得一使用者之手指的影像。取像單元11包含攝像鏡頭，攝像鏡頭之元件例如為電荷耦合元件（charge-coupled device, CCD）。取像單元11主要係取得使用者手部的影像，特別是手勢的影像。
The image capturing unit 11 can obtain an image of a user's finger. The image capturing unit 11 includes an imaging lens, and an element of the imaging lens is, for example, a charge-coupled device (CCD). The image capturing unit 11 mainly acquires an image of the user's hand, particularly an image of a gesture.
在取像單元11取得影像之後，分析單元12可分析影像並得到一密碼並比對該密碼與一預設密碼。在本實施例中，影像分析主要是取得手掌影像中手指的數目以對應一密碼，密碼包含數字，特別是1～5的整數。在分析一連串的影像並得到一組含數字之密碼之後，可比對該密碼與一預設密碼，若二組互相吻合，則依據一第一比對結果輸出一比對確認信號。
After the image capturing unit 11 acquires the image, the analyzing unit 12 can analyze the image and obtain a password and compare the password with a preset password. In this embodiment, the image analysis mainly obtains the number of fingers in the palm image to correspond to a password, and the password includes a number, especially an integer of 1-5. After analyzing a series of images and obtaining a set of passwords containing numbers, comparing the password with a preset password, if the two groups match each other, an alignment confirmation signal is output according to a first comparison result.
然後，鎖具驅動單元14可接收比對確認信號以驅動電磁鎖13，進而解鎖。
Then, the lock driving unit 14 can receive the comparison confirmation signal to drive the electromagnetic lock 13 to unlock.
圖2A為分析單元12進行手勢影像分析的辨識過程示意圖。其中，分析單元12係依據影像之一特定灰階值在一方向（例如水平方向）連續的數量來分析影像。當取像單元11取得的手勢影像經二值化影像處理後可得到一個黑白的影像，此黑白影像的處理可強化手勢外形、並適度降低其餘位置之雜訊。然後，由左向右、由下往上掃描整個影像，當每一水平掃描線上之連續黑色像素（特定灰階值）數量大於一預定值時，可代表掃描到手腕、手掌區域，並可將此一區域清除。而當連續黑色像素數量小於某一預定值時，係將此一區域清除，此為可能之雜訊。當全圖掃描完後，可得到分離之區塊，計算分離區塊數量後即可轉換為數值，即代表手指之數目。如此即得到該組密碼之其中一數字。
FIG. 2A is a schematic diagram of an identification process of the gesture unit analysis performed by the analysis unit 12. The analyzing unit 12 analyzes the image according to the number of consecutive grayscale values of one of the images in a direction (for example, a horizontal direction). When the gesture image acquired by the image capturing unit 11 is processed by the binarized image, a black and white image can be obtained, and the processing of the black and white image can enhance the shape of the gesture and moderately reduce the noise of the remaining positions. Then, scanning the entire image from left to right and from bottom to top. When the number of consecutive black pixels (specific grayscale values) on each horizontal scan line is greater than a predetermined value, it can represent scanning to the wrist, palm area, and This area is cleared. When the number of consecutive black pixels is less than a predetermined value, the area is cleared, which is a possible noise. After the whole image is scanned, the separated blocks can be obtained, and the number of separated blocks can be calculated and converted into a numerical value, that is, the number of fingers. Thus, one of the numbers of the set of passwords is obtained.
另外，圖2B為分析單元12進行手勢影像分析之另一辨識過程的示意圖。其中，分析單元12係依據影像之二特定灰階值之交界處之折返次數來分析影像。在二值化的黑白影像邊緣上，由下往上順時鐘方向追蹤黑、白像素（二特定灰階值）交界處，並記錄“下→上→下…”的折返次數（”下”請注意實線箭頭，”上”請注意虛線箭頭），即可得知影像中的手指數目，再轉換為數值。
In addition, FIG. 2B is a schematic diagram of another identification process of the gesture unit analysis by the analysis unit 12. The analysis unit 12 analyzes the image according to the number of foldbacks at the intersection of the two specific grayscale values of the image. On the edge of the binarized black and white image, track the black and white pixels (two specific grayscale values) at the intersection of the clockwise direction from bottom to top, and record the number of folds of "down → up → down..."("下" Pay attention to the solid arrow, "up" please pay attention to the dotted arrow), you can know the number of fingers in the image, and then convert to a value.
需注意者，上述特定灰階值除了定義為一特定值之外，也定義為一特定範圍。
It should be noted that the above specific grayscale value is defined as a specific range in addition to being defined as a specific value.
