物體感應控制的實物攝影機與相關方法Object camera and related method for object sensing control

本發明是有關於一種物體感應控制的實物攝影機與相關方法,且特別是有關於一種在擷取畫面時依據畫面差異實現物體感應控制的實物攝影機與相關方法。The present invention relates to a physical camera and related method for object sensing control, and more particularly to a physical camera and related method for realizing object sensing control according to a screen difference when capturing a picture.

實物攝影機可擷取各種實物的影像,並即時將影像輸出以進行播放/投影。實物攝影機已被廣泛運用於教學與展示、演講等各種用途。The physical camera captures images of various objects and instantly outputs the images for playback/projection. Physical cameras have been widely used in teaching, presentation, and presentations.

在先前技術的實物攝影機中,使用者需經由實物攝影機上設置的實體功能按鍵來控制實物攝影機的各種功能。然而,此種控制技術較為間接,無法為實物攝影機提供友善直覺的人機介面。In prior art physical cameras, the user has to control the various functions of the physical camera via physical function buttons provided on the physical camera. However, this kind of control technology is indirect and cannot provide a friendly and intuitive human-machine interface for physical cameras.

為了減少使用者與實物攝影機間的隔閡,本發明為實物攝影機提供友善的物體感應控制機制,讓使用者能直覺、自然、有效率地以物體的動作直接控制實物攝影機。In order to reduce the gap between the user and the physical camera, the present invention provides a friendly object sensing control mechanism for the physical camera, allowing the user to intuitively, naturally, and efficiently control the physical camera with the motion of the object.

以辨認/追蹤手勢/動作實現的人機介面技術中,包括有基於手套(glove-based)的技術與視覺基礎(vision based)的技術。在基於手套的技術中,使用者需使用裝有感應器的手套來控制機器,但其成本高昂,使用者活動受限,長期配戴手套也會造成使用者的負擔,實用性與方便性均受限。視覺基礎的技術可區分為二,其一是以輪廓為基礎(contour-based),另一則是以模型為基礎(model based)。在輪廓基礎的技術中,由於手勢運動與視覺背景間會相互干擾,必須解決邊緣取出與手指間相互遮蔽的問題。模型基礎的技術中則要設計特殊的模型演算法,且演算法的執行相當複雜耗時,很難達成即時控制。The human interface technology for recognizing/tracking gestures/actions includes techniques based on glove-based technology and vision based. In the glove-based technology, the user needs to use the glove with the sensor to control the machine, but the cost is high, the user's activity is limited, and the long-term wearing of the glove will also cause the user's burden, practicality and convenience. Limited. The technology of visual basis can be divided into two, one is contour-based and the other is model based. In the contour-based technique, since the gesture motion and the visual background interfere with each other, it is necessary to solve the problem that the edge is taken out and the fingers are shielded from each other. In the model-based technology, special model algorithms are designed, and the execution of the algorithms is quite complicated and time-consuming, and it is difficult to achieve immediate control.

本發明的目的之一是提供一種物體感應控制的實物攝影機,包含一攝影裝置、一輸出裝置與一處理器。攝影裝置依序擷取複數畫面;輸出裝置依序輸出各畫面,並於各畫面上顯示預設數目個功能視窗,各功能視窗對應實物攝影機的一項功能。一處理器則可依據畫面間的差異決定是否啟動各功能視窗對應的功能。One of the objects of the present invention is to provide a physical camera for object sensing control, comprising a photographing device, an output device and a processor. The photographing device sequentially captures the plurality of screens; the output device sequentially outputs the screens, and displays a preset number of function windows on each screen, and each function window corresponds to a function of the physical camera. A processor can determine whether to activate the function corresponding to each function window according to the difference between the screens.

一實施例中,處理器提供/實現一濾波模組、一偵測模組與一判斷模組。濾波模組於各畫面上分割出預設數目個偵測視窗,並於各偵測視窗擷取一對應的畫面特徵。其中,各偵測視窗對應一功能視窗。偵測模組依序比較各偵測視窗於兩不同畫面的對應畫面特徵以產生一比較結果,並依據複數個比較結果的堆疊來偵測各偵測視窗是否發生畫面變化。當發生畫面變化的偵測視窗的個數符合一預設值,判斷模組針對有畫面變化的偵測視窗啟動其所對應的功能。再者,判斷模組亦可記錄一或多個視窗組合,每一視窗組合對應實物攝影機的一項功能;當發生畫面變化的偵測視窗符合其中一視窗組合,判斷模組便可啟動相符視窗組合所對應的功能。濾波模組可以是一索貝爾(Sobel)濾波模組。In one embodiment, the processor provides/implements a filter module, a detection module, and a determination module. The filtering module divides a preset number of detection windows on each screen, and captures a corresponding picture feature in each detection window. Each detection window corresponds to a function window. The detection module sequentially compares the corresponding picture features of the two detection windows on the two different pictures to generate a comparison result, and detects whether the detection window changes according to the stack of the plurality of comparison results. When the number of detection windows in which the picture changes occur corresponds to a preset value, the determination module activates the corresponding function for the detection window with the picture change. Furthermore, the judging module can also record one or more window combinations, each window combination corresponding to a function of the physical camera; when the detection window of the screen change conforms to one of the window combinations, the judging module can start the matching window. Combine the functions corresponding to it. The filter module can be a Sobel filter module.

一實施例中,實物攝影機可設置一實體的感應啟始按鍵,控制輸出裝置是否顯示功能視窗,並控制濾波模組、偵測模組與判斷模組是否運作。In one embodiment, the physical camera can be configured with a physical inductive start button, control whether the output device displays the function window, and control whether the filter module, the detection module, and the judging module operate.

本發明的又一目的是提供應用於前述實物攝影機以進行物體感應控制的方法。It is still another object of the present invention to provide a method of applying the above-described physical camera for object sensing control.

為了對本發明之上述及其他方面有更佳的瞭解,下文特舉較佳實施例,並配合所附圖式,作詳細說明如下:In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:

請參考第1圖,其所示意的是依據本發明一實施例的一實物攝影機10。實物攝影機10設有一攝影裝置12、一處理器14與一輸出裝置16。攝影裝置12可以包括感光偵測器矩陣與相關的光學模組,以依照一定的時序(頻率)依序擷取複數畫面,如畫面Fi(t)。處理器14控制實物攝影機10的運作,輸出裝置16則可依照時序將攝影裝置12所擷取的畫面Fi(t)輸出為畫面Fo(t),以形成即時動態影像。Referring to Figure 1, there is shown a physical camera 10 in accordance with an embodiment of the present invention. The physical camera 10 is provided with a photographing device 12, a processor 14 and an output device 16. The photographing device 12 may include a photodetector matrix and an associated optical module to sequentially capture a plurality of pictures, such as a picture Fi(t), according to a certain timing (frequency). The processor 14 controls the operation of the physical camera 10, and the output device 16 outputs the screen Fi(t) captured by the photographing device 12 to the screen Fo(t) in accordance with the timing to form an instant motion image.

為實現本發明的物體感應控制,處理器14可提供/實現一濾波模組18、一比較模組20與一判斷模組22,並使輸出裝置16輸出的畫面Fo(t)上可以顯示出K個功能視窗f(1)、f(2)、...、f(k)至f(K),每個功能視窗f(k)對應實物攝影機10的一項功能。而處理器14即可依據各功能視窗在不同畫面間(如前後相鄰畫面Fi(t-1)與Fi(t)間)的差異而決定是否執行各功能視窗對應的功能,以實現出物體感應控制的人機介面。使用者可以在攝影裝置12的攝影範圍內直接以操控物體26(如手指、筆、指示裝置…等)在各功能視窗的對應位置進行操控;當處理器14由攝影裝置12擷取的影像中感應出某一功能視窗f(k)內已出現操控動作,即可執行該功能視窗f(k)所對應的功能。To implement the object inductive control of the present invention, the processor 14 can provide/implement a filter module 18, a comparison module 20 and a determination module 22, and can display the image Fo(t) output by the output device 16 K function windows f(1), f(2), ..., f(k) to f(K), each function window f(k) corresponds to a function of the physical camera 10. The processor 14 can determine whether to execute the function corresponding to each function window according to the difference between the different screens (such as between the front and rear adjacent screens Fi(t-1) and Fi(t)) to realize the object. Inductively controlled human interface. The user can directly manipulate the object 26 (such as a finger, a pen, a pointing device, etc.) in the corresponding position of each function window within the shooting range of the photographing device 12; when the processor 14 is captured by the photographing device 12, It is detected that a control action has occurred in a function window f(k), and the function corresponding to the function window f(k) can be executed.

在進行前述物體感應控制時,濾波模組18可於各畫面Fi(t)上分割出N個偵測視窗d(1)、d(2)、...、d(n)至d(N),並於各偵測視窗d(n)中擷取一對應的畫面特徵。其中,各偵測視窗d(n)對應某一功能視窗f(k)。偵測模組20比較各偵測視窗d(n)於兩不同畫面(如前後相鄰畫面Fi(t-1)與Fi(t)間)的對應畫面特徵以產生一比較結果,並依據連續複數個比較結果的堆疊來偵測各偵測視窗d(n)中是否發生畫面變化。當使用者在某功能視窗f(k)的對應位置進行操控時,在該功能視窗f(k)所對應的偵測視窗d(n)中會發生畫面變化,而判斷模組22即可依據各偵測視窗d(n)中是否發生畫面變化來判斷使用者是否要執行對應功能視窗f(k)的功能。When the object sensing control is performed, the filtering module 18 can segment the N detecting windows d(1), d(2), ..., d(n) to d(N) on each screen Fi(t). ), and capture a corresponding picture feature in each detection window d(n). Each detection window d(n) corresponds to a certain function window f(k). The detecting module 20 compares the corresponding picture features of the detection windows d(n) on two different pictures (such as between the front and rear adjacent pictures Fi(t-1) and Fi(t)) to generate a comparison result, and according to the continuous A stack of multiple comparison results is used to detect whether a picture change has occurred in each detection window d(n). When the user controls in the corresponding position of a function window f(k), a screen change occurs in the detection window d(n) corresponding to the function window f(k), and the determination module 22 can be based on Whether or not a screen change occurs in each detection window d(n) determines whether the user wants to execute the function corresponding to the function window f(k).

在一實施例中,濾波模組18可以是一索貝爾濾波模組,在畫面Fi(t)的各偵測視窗d(n)中進行索貝爾濾波運作以擷取影像邊緣。偵測模組20則可比較各偵測視窗d(n)於相鄰畫面Fi(t-1)與Fi(t)間的影像邊緣差異。一實施例中,偵測模組20可為各偵測視窗d(n)連續比較一連串的相鄰畫面,如畫面Fi(t-5)與Fi(t-4)、Fi(t-4)與Fi(t-3)、Fi(t-3)與Fi(t-2)、Fi(t-2)與Fi(t-1)、Fi(t-1)與Fi(t),並將各相鄰畫面的比較結果堆疊起來,綜合判斷各偵測視窗d(n)中是否發生畫面變化。In an embodiment, the filter module 18 can be a Sobel filter module, and the Sobel filtering operation is performed in each detection window d(n) of the screen Fi(t) to capture the edge of the image. The detection module 20 can compare the image edge differences between the adjacent frames Fi(t-1) and Fi(t) in each detection window d(n). In one embodiment, the detection module 20 can continuously compare a series of adjacent pictures for each detection window d(n), such as pictures Fi(t-5) and Fi(t-4), Fi(t-4). And Fi(t-3), Fi(t-3) and Fi(t-2), Fi(t-2) and Fi(t-1), Fi(t-1) and Fi(t), and The comparison results of the adjacent pictures are stacked, and it is comprehensively judged whether or not a picture change occurs in each detection window d(n).

例如說,若一物體在時間(t-4)進入至某一偵測視窗d(n),偵測視窗d(n)會在畫面Fi(t-5)與Fi(t-4)之間發生畫面特徵的差異;若畫面Fi(t-4)與Fi(t-3)、Fi(t-3)與Fi(t-2)、Fi(t-2)與Fi(t-1)、Fi(t-1)與Fi(t)的比較結果反映出該物體的影像持續出現在偵測視窗d(n),則可判定視窗d(n)已發生畫面變化。相對地,若畫面Fi(t-4)與Fi(t-3)的比較結果反映出該物體的影像未持續,則可判定視窗d(n)尚未發生變化;畫面Fi(t-5)與Fi(t-4)的畫面特徵差異是由高頻雜訊及/或快速背景改變所形成的誤報。也就是說,利用比較結果的堆疊來判斷各偵測視窗是否有畫面變化,可以有效防止高頻雜訊與快速背景改變影響物體感應控制。For example, if an object enters a detection window d(n) at time (t-4), the detection window d(n) will be between the screens Fi(t-5) and Fi(t-4). The difference in picture characteristics occurs; if the pictures Fi(t-4) and Fi(t-3), Fi(t-3) and Fi(t-2), Fi(t-2) and Fi(t-1), The comparison result of Fi(t-1) and Fi(t) reflects that the image of the object continues to appear in the detection window d(n), and it can be determined that the window d(n) has undergone a screen change. In contrast, if the comparison result of the screen Fi(t-4) and Fi(t-3) reflects that the image of the object does not continue, it can be determined that the window d(n) has not changed; the screen Fi(t-5) and The difference in picture characteristics of Fi(t-4) is a false positive caused by high frequency noise and/or fast background changes. That is to say, using the stack of comparison results to determine whether there is a picture change in each detection window, it can effectively prevent high frequency noise and rapid background change from affecting object sensing control.

為了進一步避免大範圍背景光影變化與雜訊對物體感應控制的影響,當同時發生畫面變化的偵測視窗的個數符合一預設值時,判斷模組22才會針對有畫面變化的偵測視窗執行其所對應的功能。舉例而言,此預設值可以是1;也就是說,若在某一時間中同時有2個或更多個偵測視窗都發生畫面變化,判斷模組22不會執行任何功能。若某一時間中只有一個偵測視窗發生畫面變化,判斷模組22才會執行該偵測視窗/功能視窗所對應的功能。背景光影變化會使多個偵測視窗同時發生畫面變化,故判斷模組22不會予以回應,以避免此種狀況錯誤觸發各項功能。此外,當使用者更換攝影裝置12前的文件或是調整其焦距時,也會使多個偵測視窗皆發生畫面變化;而判斷模組22亦會排除此種狀況。In order to further avoid the influence of large-scale background light and shadow changes and noise on the object sensing control, when the number of detection windows of the simultaneous screen change meets a preset value, the determining module 22 will detect the change of the screen. The window performs its corresponding function. For example, the preset value may be 1; that is, if two or more detection windows are simultaneously changed in a certain time, the determination module 22 does not perform any function. If only one detection window changes the screen during a certain time, the judgment module 22 performs the function corresponding to the detection window/function window. The background light and shadow change will cause multiple screens to change at the same time, so the judgment module 22 will not respond to avoid such a situation from erroneously triggering various functions. In addition, when the user replaces the file before the photographing device 12 or adjusts the focal length thereof, the screens of the plurality of detection windows are also changed; and the judging module 22 also excludes the situation.

再者,判斷模組22也可記錄一或多組視窗組合,每一視窗組合對應該實物攝影機10的一項功能。當發生畫面變化的偵測視窗符合其中一視窗組合,判斷模組22會執行相符視窗組合所對應的功能。例如說,某一視窗組合是將兩個偵測視窗d(n1)與d(n2)對應某一項功能(其中n1與n2為兩定值);當偵測視窗d(n1)與d(n2)同時發生畫面變化且其餘偵測視窗皆未發生畫面變化時,判斷模組22就會執行該項功能。Moreover, the determination module 22 can also record one or more sets of window combinations, each of which corresponds to a function of the physical camera 10. When the detection window of the screen change conforms to one of the window combinations, the determination module 22 performs the function corresponding to the matching window combination. For example, a certain window combination is to associate two detection windows d(n1) and d(n2) with a certain function (where n1 and n2 are two fixed values); when detecting windows d(n1) and d(() N2) When the screen change occurs at the same time and no change occurs in the remaining detection windows, the judgment module 22 performs the function.

在一實施例中,實物攝影機10可設置一實體的感應啟始按鍵24,以控制物體感應控制的啟始與結束。例如說,當實物攝影機10未開始物體感應控制機制時,使用者可按動此感應啟始按鍵24以開始進行物體感應控制;實物攝影機10會在輸出畫面Fo(t)上顯示各功能視窗f(k),而處理器14的濾波模組18、偵測模組20與判斷模組22也會開始運作。當使用者再度按動感應啟始按鍵24後,實物攝影機10可以停止物體感應控制:實物攝影機10不再於畫面Fo(t)上顯示各功能視窗,而濾波模組18、偵測模組20與判斷模組22也會停止運作。濾波模組18、偵測模組20與判斷模組22可用硬體、韌體及/或軟體來實現。In one embodiment, the physical camera 10 can be provided with a physical induction start button 24 to control the initiation and end of the object sensing control. For example, when the physical camera 10 does not start the object sensing control mechanism, the user can press the sensing start button 24 to start the object sensing control; the physical camera 10 displays the function windows f on the output screen Fo(t). (k), and the filter module 18, the detection module 20 and the determination module 22 of the processor 14 also start to operate. When the user presses the induction start button 24 again, the physical camera 10 can stop the object sensing control: the physical camera 10 no longer displays the function windows on the screen Fo(t), and the filtering module 18 and the detecting module 20 The judgment module 22 also stops operating. The filter module 18, the detection module 20 and the determination module 22 can be implemented by hardware, firmware and/or software.

請參考第2圖,其係依據本發明一實施例的流程100;實物攝影機10實現物體感應控制的機制可用流程100來說明。流程100的主要步驟可描述如下:步驟102:開始物體感應控制。例如說,使用者可按動感應啟始按鍵24以開始流程100。Please refer to FIG. 2, which is a flow 100 according to an embodiment of the present invention; the mechanism for implementing object sensing control by the physical camera 10 can be illustrated by the process 100. The main steps of the process 100 can be described as follows: Step 102: Start object sensing control. For example, the user can press the induction start button 24 to begin the process 100.

步驟104:實物攝影機10將功能視窗重疊顯示於攝影裝置12所擷取到的畫面,並將合成畫面輸出予使用者。Step 104: The physical camera 10 superimposes the function window on the screen captured by the photographing device 12, and outputs the synthesized screen to the user.

步驟106:濾波模組18、偵測模組20與判斷模組22進行運作,依據各偵測視窗是否出現畫面變化判斷各功能視窗是否被觸發。若是,則進行至步驟108;反之則遞迴至步驟104以持續進行畫面比較與物體偵測。Step 106: The filtering module 18, the detecting module 20 and the determining module 22 operate, and determine whether each function window is triggered according to whether a screen change occurs in each detecting window. If yes, proceed to step 108; otherwise, return to step 104 to continue the screen comparison and object detection.

步驟108:當某功能視窗已被觸動,便可執行該功能視窗對應的功能。Step 108: When a function window has been touched, the function corresponding to the function window can be executed.

請參考第3至第6圖,其所示意的是依據本發明一實施例的物體感應控制運作情形。在第3圖中,使用者先按動感應啟始按鍵24以啟動實物攝影機10的物體感應控制機制。實物攝影機10會在輸出的畫面28a上顯示兩功能視窗f(a1)與f(a2),例如說,功能視窗f(a1)對應的是選單功能。若使用者想要觸動功能視窗f(a1)的功能,使用者可用操控物體26(如手指、筆、指示裝置…等)重疊於功能視窗f(a1)所對應的偵測視窗d(a1)上;此時,使用者會在輸出的畫面28a上看到功能視窗f(a1)疊合覆蓋於操控物體26上,當然亦可改變顯示為操控物體26疊合於功能視窗f(a1)上。Please refer to Figures 3 to 6, which illustrate the operation of the object sensing control in accordance with an embodiment of the present invention. In FIG. 3, the user first presses the induction start button 24 to activate the object sensing control mechanism of the physical camera 10. The physical camera 10 displays the two function windows f(a1) and f(a2) on the output screen 28a. For example, the function window f(a1) corresponds to the menu function. If the user wants to touch the function of the function window f (a1), the user can superimpose the object 26 (such as a finger, a pen, a pointing device, etc.) on the detection window d (a1) corresponding to the function window f (a1). At this time, the user will see that the function window f(a1) overlaps the manipulation object 26 on the output screen 28a, and of course, the display object 26 is superimposed on the function window f(a1). .

在第4圖中,使用者持續將操控物體26重疊於偵測視窗d(a1),等偵測模組20堆疊的比較結果反映出偵測視窗d(a1)已發生畫面變化後,實物攝影機10於輸出畫面28b上顯示「OK」,代表功能視窗f(a1)已被觸動,並開始執行功能視窗f(a1)對應的功能,例如說是啟動一幕前顯示(OSD,On-Screen Display)系統。In FIG. 4, the user continuously superimposes the control object 26 on the detection window d (a1), and the comparison result of the detection module 20 stack reflects that the detection window d (a1) has undergone a screen change, the physical camera 10 displays "OK" on the output screen 28b, indicating that the function window f(a1) has been touched, and starts to execute the function corresponding to the function window f(a1), for example, to start the screen display (OSD, On-Screen Display). system.

在第5圖中,實物攝影機10啟動幕前顯示系統,在輸出畫面28c上顯示幕前顯示系統的各功能視窗f(b1)至f(b10),分別對應實物攝影機10的各種功能,例如訊源切換、凍結畫面、播放、自動對焦、解析度調整、亮度調整、對比調整等等。各功能視窗f(b1)至f(b10)可沿L形(或例如:U形)排列於輸出畫面的底側與右側及/或左側。使用者要觸動其中一功能時,只要在攝影裝置12之前將操控物體26重疊於各功能視窗對應的偵測視窗即可。In Fig. 5, the physical camera 10 activates the pre-screen display system, and displays the function windows f(b1) to f(b10) of the pre-screen display system on the output screen 28c, respectively corresponding to various functions of the physical camera 10, for example, Source switching, freeze screen, playback, auto focus, resolution adjustment, brightness adjustment, contrast adjustment, and more. Each of the function windows f(b1) to f(b10) may be arranged in an L shape (or, for example, a U shape) on the bottom side and the right side and/or the left side of the output screen. When the user wants to touch one of the functions, it is only necessary to superimpose the manipulation object 26 on the detection window corresponding to each function window before the photographing device 12.

第5圖的功能視窗f(b10)可以對應「關閉幕前顯示系統」的功能。當使用者要結束第5圖的幕前顯示系統,便可如第6圖所示般在輸出畫面28d中將操控物體26重疊至功能視窗f(b10)所對應的偵測視窗d(b10),使實物攝影機10能感應到偵測視窗d(b10)的畫面變化,並執行功能視窗f(b10)的對應功能,退出幕前顯示系統。The function window f (b10) in Fig. 5 can correspond to the function of "turn off the front display system". When the user wants to end the front-end display system of FIG. 5, the control object 26 can be superimposed on the output screen 28d to the detection window d corresponding to the function window f (b10) as shown in FIG. 6 (b10). The physical camera 10 can sense the change of the screen of the detection window d (b10), and execute the corresponding function of the function window f (b10) to exit the front display system.

總結來說,相較於習知實物攝影機的實體按鍵式控制介面,本發明可利用實物攝影機既有的架構實現友善直覺的物體感應控制介面,讓使用者能直接用操控物體方便自然地操控實物攝影機的各項功能。In summary, compared with the physical button control interface of the conventional physical camera, the present invention can realize the friendly and intuitive object sensing control interface by using the existing structure of the physical camera, so that the user can directly and conveniently manipulate the physical object by directly controlling the object. The various functions of the camera.

綜上所述,雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,本發明之保護範圍當視後附之申請專利範圍所界定者為準。In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention.
