201126451 六、發明說明： 【發明所屬之技術領威】 本發明係有關於一種具傷初始定位的擴增實境系統及 方法’特別是有關於一種具锖初始定位的擴增實境系統及 方法可藉由擴增實境内容分別具有虛擬空間之座標對應於 實體空間之座標，而直接在顯示螢幕上看到所對應的專屬 的擴增實境的内容。 【先前技術】 近年來三維影像處理技術漸趨成熟，因此有許多廠商 選擇改以立體化影像來取代原本二維（平面）的行銷與宣 傳，而此行銷手法的突破，擴增實境(Augmented Reality) 技術的成熟乃佔了相當重要的地位，實際上，擴增實境技 術乃是以VR虛擬實境(Virtual Reality)為出發的新互動技 術，透過虚擬實境設備，係得將實際上並不存在現場的物 件或景象，投影在指定的真實空間，如此一來，操作者便 可藉由擴增實境系統，進行資訊展示或取得。 擴增實境發展至今也有近十數年的時間，跟虛擬實境 不同的是，虛擬實境是無中生有，從頭創造出一個不存在 的世界，擴增實境則是著重在與真實世界的結合，增強真 實世界裡的資訊顯示與互動經驗。多數人較為熟悉者乃是 虛擬實境，相關的應用也較為廣泛，像是三百六十度的環 場全景、虛擬攝影棚、飛行模擬器，以及大型社交平台 Second Life等，都是虛擬實境的變形與應用，然而虛擬實 201126451 境發展表較成熟，但是限制也越來越明顯。首先，可以讓 人感動的虛擬實境，大多需要特定的環境跟設備，才有辦 法真正重建一個環境，並且提供堪稱豐富的互動跟内容， 要做一個虛擬實境不難，但是產製出一個豐富且吸引人， 或是可以達成特定目的（像是飛行訓練等）的虛擬實境，那 得從頭打造一個環境，甚至是一個自成一格的小小世界， 難度真的很高，而且虛擬跟真實差距太遠，沒有辦法跟曰 常生活相連結，虛擬畢竟只是虛擬，實際的空間感、光感， 甚至是第六感，還是到現場最清楚。 現階段習知擴增實境系統，先拍攝一影像之標記，辨 識該影像之標記，然後取出該標記所對應之擴增實境影 像，其中所對應之擴增實境影像與該影像互相疊合。然而， 在進行大範圍之擴增實境影像的應用時，則須先提供許多 標記作為不同影像之拍攝，如此將造成使用上之不便。 因此，便有需要提供一種具備初始定位的擴增實境系 統及方法，能夠解決前述的問題。 【發明内容】 本發明提供一種具備初始定位的擴增實境系統，其包

20拍攝實體標記完成初始定位之後，可利用『位置感知裝 置（例如陀螺儀）』量測虛擬標記56拍攝點之位置及角度， 以定位該虛擬標記56於該實體空間之座標。使用者即可在 9 201126451 附近自由活動，並直接在顯示螢幕22上看到所對應的『專 屬的』擴增實境影像的内容。此時，使用者就不需要再一 直拍攝實體標記而可自由活動。 該具備初始定位的擴增實境系統100另包括一時間計

例如每30秒，在同一空間位置，更換所對應之擴增實境影 像於該顯示螢幕中。圖4顯示在30秒時所對應之擴增實境 内容於該顯示螢幕中。 請參閱圖5，該資料庫10另包括一第二資料，該第二 資料儲存有複數個擴增實境内容，該些擴增實境内容分別 具有一第二虛擬空間之座標(X”，y’’，z”）。該攝影裝置20 另拍攝一第二實體影像(例如小花），該第二實體影像包括 一第二標記54。該辨識及定位模組30用以辨識該第二實 體影像之第二標記54，並初始定位該第二標記54於一實 體空間之一座標（x2, y2, z2)，其中該實體空間之該座標(x2, y2, z2)對應於該虛擬空間之座標（x2”，y2”，z2”）該影像建 構模組40依據該虛擬空間之座標（x2’’，y2”，z2”）對應於該 實體空間之座標(x2, y2, z2)，從該資料庫之第二資料中取 201126451 出該第二標記54所對應之擴增實境影像，其中該第二標記 54所對應之擴增實境影像與該第二實體影像互相疊合於該 顯示螢幕中。 請參閱圖1及圖6，該位置感知裝置24可定位該虛擬 標記56於該實體空間之預定座標(x3,y3,z3)，其中該實體 空間之該預定座標（x3，y3，z3)對應於該虛擬空間之座標 (x3’’，y3’’，z3”）。該影像建構模組40依據該虛擬空間之座 標（x3”，y3”，z3”）對應於該實體空間之座標(x3, y3, z3)，從 該資料庫10内之第二資料中取出該虛擬標記56所對應之 擴增實境影像(例如小貓之虛擬影像），該虛擬標記56所對 應之擴增實境影像呈現於該顯示螢幕中。詳細而言，當攝 影裝置20拍攝實體標記完成初始定位之後，可利用『位置 感知裝置（例如陀螺儀）』量測虛擬標記56拍攝點之位置及 角度，以定位該虛擬標記56於該實體空間之座標。 請注意，第一標記52(實體標記）完成初始化設定之 後，轉動攝影機到該某一定位點所顯示的是虛擬標記5 6 (如 圖3所示），其對應一個"擴增實境内容而第二標記54(實 體標記）完成初始化設定之後，轉動攝影機到前述該相同定 位點，亦顯示的是虛擬標記56(如圖6所示），則是對應另 一個π擴增實境内容"。意即，雖然攝影機對準同樣虛擬標 記的位置，但如果初始化設定不同的實體標記，其擴增實 境内容會是不同的。舉例，具有該虛擬空間之座標（x3”，y3’’， z3”）的擴增實境内容（例如小貓之虛擬影像）不同於具有該 11 201126451 虛擬空間之座標(x3’，y3’，z3’）的擴增實境内容（例如小狗之 虛擬影像）。 請參閱圖7,其繪示本發明之一實施例之具備初始定 位的擴增實境方法流程圖。一種具備初始定位的擴增實境 方法，包括下列步驟：

The coordinates. Users can freely move around 9 201126451 and directly see the contents of the corresponding "Actual Augmented Reality Image" on the display screen 22. At this point, the user does not need to take the physical mark again and is free to move. The augmented reality system 100 with initial positioning further includes a time counting device 42 whereby the augmented reality content can be a time series, each having a virtual time coordinate, the virtual time coordinate (t' Corresponding to a physical time coordinate (t), the image construction module 40 corresponds to the coordinates of the physical time (X, according to the coordinates of the virtual space and time (X', y', z', t'). y, z, t), the corresponding augmented reality images are taken out from the augmented reality images at the same spatial location in the display screen. In detail, the corresponding augmented reality image is replaced in the display screen at a same spatial position as time varies, for example every 30 seconds. Figure 4 shows the augmented reality content corresponding to the display at 30 seconds. Referring to FIG. 5, the database 10 further includes a second data, where the second data is stored with a plurality of augmented reality contents, and the augmented reality contents respectively have coordinates (X" of a second virtual space. y'',z"). The camera device 20 also captures a second physical image (e. g., a small flower), and the second physical image includes a second indicia 54. The identification and positioning module 30 is configured to identify the second mark 54 of the second entity image, and initially locate the second mark 54 in a coordinate space (x2, y2, z2) of the physical space, wherein the physical space The coordinates (x2, y2, z2) correspond to the coordinates (x2", y2", z2" of the virtual space. The image construction module 40 corresponds to the coordinates (x2'', y2", z2") of the virtual space. The coordinates (x2, y2, z2) of the physical space are taken from the second data of the database, and the augmented reality image corresponding to the second mark 54 is taken out from the second data of the database, wherein the second mark 54 corresponds to the amplification The real image and the second entity image are superimposed on each other in the display screen. Referring to FIG. 1 and FIG. 6, the position sensing device 24 can position the virtual marker 56 at a predetermined coordinate of the physical space (x3, y3, z3). ), wherein the predetermined coordinates (x3, y3, z3) of the physical space correspond to coordinates (x3'', y3'', z3") of the virtual space. The image construction module 40 extracts the second data in the database 10 according to the coordinates (x3, y3, z3") of the virtual space corresponding to the coordinates (x3, y3, z3) of the physical space. The augmented reality image corresponding to the virtual marker 56 (for example, a virtual image of a kitten), and the augmented reality image corresponding to the virtual marker 56 is presented in the display screen. In detail, when the photographing device 20 captures the physical marker After the initial positioning is completed, the position and angle of the virtual marker 56 can be measured by a position sensing device (eg, a gyroscope) to locate the coordinates of the virtual marker 56 in the physical space. Note that the first marker 52 ( Entity Mark) After the initial setting is completed, turning the camera to the certain anchor point displays a virtual marker 56 (as shown in Figure 3), which corresponds to an "augmented reality content and a second marker 54 (entity marker) After the initialization setting is completed, the camera is rotated to the same positioning point as described above, and the virtual mark 56 (shown in FIG. 6) is displayed, which corresponds to another π augmented reality content. The camera is aimed at the same virtual mark, but if the entity mark is initialized and set, the augmented reality content will be different. For example, the coordinates of the virtual space (x3", y3'', z3") Augmented content (such as a virtual image of a kitten) is different from augmented reality content (such as a virtual image of a puppy) with coordinates (x3', y3', z3') of the 11 201126451 virtual space. 7. A flow chart of an augmented reality method with initial positioning according to an embodiment of the present invention. An augmented reality method with initial positioning includes the following steps: In step 200, a plurality of amplifications are stored. The content of the augmented reality has a coordinate of the virtual space; in step 202, a camera device is provided for capturing a first entity image, wherein the first entity image includes a first mark; In step 204, the first mark of the first entity image is identified, and the first mark is located at a first coordinate of a physical space, wherein the first coordinate of the physical space corresponds to the first mark a first one of the coordinates of the virtual space; and in step 206, extracting the expansion corresponding to the first mark from the augmented reality content according to the coordinate of the virtual space corresponding to the coordinate of the physical space The augmented reality content, wherein the augmented reality content corresponding to the first mark and the first entity image overlap each other in the display screen. The augmented reality method with initial positioning further includes the following steps: a virtual mark in a predetermined coordinate of the physical space, wherein a predetermined coordinate of the physical space corresponds to a second one of the coordinates of the virtual space; and a coordinate corresponding to the physical space according to a coordinate of the virtual space 12 201126451 The augmented reality content corresponding to the virtual mark is extracted from the augmented reality content, and the augmented reality content corresponding to the virtual mark is presented on the display screen. The augmented reality system and method with initial positioning according to the present invention, wherein the database stores a plurality of augmented reality contents, and the augmented reality contents respectively have coordinates of the virtual space corresponding to the physical space. Coordinates, when measuring the position and angle of the shooting point of the virtual marker, you can directly see the corresponding "exclusive" augmented reality content on the display screen, so you can still do it without many physical markers.
