Description
本發明涉及照相機領域，尤其係涉及一種全景相機。 The present invention relates to the field of cameras, and more particularly to a panoramic camera.
傳統相機多由單個鏡頭組成，在成像過程中與被攝物成相對靜止狀態，其拍攝角度取決於單個鏡頭之視角大小，而通常之標準鏡頭之視角約50度左右，故其無法應用於拍攝風光及集體紀念照等場景。 Conventional cameras are mostly composed of a single lens. They are relatively stationary with the subject during imaging. The angle of view depends on the angle of view of a single lens. Normally, the angle of view of a standard lens is about 50 degrees, so it cannot be used for shooting. Scenes such as scenery and collective commemorative photos.
廣角鏡頭之拍攝角度會寬廣很多，一般之廣角鏡頭視角可超過90度，魚眼鏡頭可以超過180度，但目前卻無360度視角之全景相機。如果使用者需要拍攝360度全景之照片，則拍攝時需要使用平穩之三腳架水平旋轉鏡頭拍攝，然後通過接圖軟體對圖像進行處理，但旋轉鏡頭需要使用複雜之驅動裝置且製造難度較高。 Wide-angle lens shooting angle will be much wider, the general wide-angle lens angle can exceed 90 degrees, the fisheye lens can exceed 180 degrees, but currently there is no 360-degree panoramic camera. If the user needs to take a 360-degree panoramic photo, then a smooth tripod horizontal rotation lens is required for shooting, and then the image is processed by the connection software, but the rotating lens requires a complicated driving device and is difficult to manufacture.
有鑑於此，有必要提供一種結構簡單及製造難度較低之全景相機。 In view of this, it is necessary to provide a panoramic camera that is simple in structure and less difficult to manufacture.
一種全景相機，其包括一外殼及複數設置於外殼上之相機模組，該每個相機模組從物側方到像側方依次收容有至少一鏡片、一反光鏡及一影像感測器，該複數相機模組之鏡頭之視角之和大於或等於360度，該全景相機還包括複數與該複數相機模組對應之觀景窗及一圖像處理器，當該反光鏡與該影像感測器之受光面之間 之夾角為90度時，入射光線最終入射至該影像感測器，當該夾角為一銳角時，入射光線經過該反光鏡反射後最終進入對應觀景窗，該圖像處理器用於將每個相機模組所拍攝之照片進行處理從而得到全景照片。 A panoramic camera includes a casing and a plurality of camera modules disposed on the casing, wherein each camera module sequentially houses at least one lens, a mirror, and an image sensor from the object side to the image side. The sum of the angles of view of the lens of the plurality of camera modules is greater than or equal to 360 degrees, and the panoramic camera further includes a plurality of viewing windows corresponding to the plurality of camera modules and an image processor, and the mirror and the image sensing Between the light receiving surfaces of the device When the angle is 90 degrees, the incident light is finally incident on the image sensor. When the angle is an acute angle, the incident light is reflected by the mirror and finally enters the corresponding viewing window, and the image processor is used to The photos taken by the camera module are processed to obtain a panoramic photo.
相較於先前技術，本發明使用之全景相機通過複數相機模組同時拍攝各自視角之圖像，然後通過圖像處理器對複數圖像進行處理，從而得到全景照片，其省去了複雜之需旋轉鏡頭之機械裝置，結構簡單且製造難度較低。 Compared with the prior art, the panoramic camera used in the present invention simultaneously captures the images of the respective angles of view through the plurality of camera modules, and then processes the plurality of images through the image processor to obtain a panoramic photo, which eliminates the complicated need. The mechanical device for rotating the lens has a simple structure and is less difficult to manufacture.

下面將結合附圖，對本發明實施例作進一步之詳細說明。 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
請一併參閱圖1至圖4，本發明第一實施例提供之一種全景相機100。該全景相機100包括一外殼11，該外殼11具有一圍合起來之側壁112與與該側壁112相連之上底板113及下底板114。該側壁112垂直設置在該上底板113與該下底板114之間。沿著該圍合側壁112之四週排佈有四個相機模組12。在下底板104上與該四個相 機模組12相對應之位置設置有四個觀景窗13。該全景相機100還包括一圖像處理器14。 Referring to FIG. 1 to FIG. 4 together, a panoramic camera 100 according to a first embodiment of the present invention is provided. The panoramic camera 100 includes a housing 11 having an enclosed side wall 112 and a bottom plate 113 and a lower floor 114 connected to the side wall 112. The side wall 112 is vertically disposed between the upper bottom plate 113 and the lower bottom plate 114. Four camera modules 12 are arranged along the circumference of the enclosed side wall 112. On the lower base plate 104 and the four phases Four viewing windows 13 are disposed at corresponding positions of the machine module 12. The panoramic camera 100 also includes an image processor 14.
每個相機模組12從物側方到像側方依次收容有一鏡片122、一反光鏡124及一影像感測器126。該影像感測器126具有一個受光面1262。該反光鏡124與該影像感測器126之受光面1262具有一夾角θ。該反光鏡124可在一馬達(圖未示)之驅動下沿著一垂直於該相機模組12之光軸方向之旋轉軸旋轉，從而實現θ角之改變。 Each camera module 12 receives a lens 122, a mirror 124 and an image sensor 126 in sequence from the object side to the image side. The image sensor 126 has a light receiving surface 1262. The mirror 124 has an angle θ with the light receiving surface 1262 of the image sensor 126. The mirror 124 can be rotated by a motor (not shown) along a rotation axis perpendicular to the optical axis of the camera module 12, thereby achieving a change in the angle θ.
該相機模組12之視角大於90度，或者該四個相機模組12之視角之和大於或等於360度。當相機模組12所收容之鏡片多於一個時，需考慮複數鏡片所組成之鏡頭之視角大小。 The camera module 12 has a viewing angle greater than 90 degrees, or the sum of the viewing angles of the four camera modules 12 is greater than or equal to 360 degrees. When the camera module 12 accommodates more than one lens, it is necessary to consider the angle of view of the lens composed of the plurality of lenses.
該圖像處理器40分別與每個相機模組12之影像感測器126電連接，用於將每個相機模組12所拍攝之照片進行處理從而得到全景照片。 The image processor 40 is electrically connected to the image sensor 126 of each camera module 12 for processing the photos taken by each camera module 12 to obtain a panoramic photo.
該全景相機100之具體使用方法為：在快門按鈕(圖未示)未被按下時，θ角為45度。此時，入射光線60經過該反光鏡124反射後最終進入觀景窗30，使我們可以透過觀景窗30看到想要拍攝之畫面。當快門按鈕(圖未示)被按下後，調節θ角為90度，即該反光鏡124與該影像感測器126之受光面1262垂直，使光線60可以成像在影像感測器126上。然後通過該圖像處理器40對每個影像感測器126之成像進行處理，得到全景照片。由於該觀景窗30設置於該全景相機100之下底板104上，所以拍照者本身不會影響拍攝。可以理解，通過按下快門按鈕而實現反光鏡124之作動，從而調整θ角為90度為先前技術，例如可以通過一控制器分別與該快門與驅動該反光鏡124之馬達連接，當收到快門按鈕按下之訊 號後該控制器控制該馬達工作從而驅動該反光鏡124旋轉至θ角為90度。先前技術中有很多技術手段用來實現該目的，在此不再贅述。 The specific use of the panoramic camera 100 is such that when the shutter button (not shown) is not pressed, the angle θ is 45 degrees. At this time, the incident light 60 is reflected by the mirror 124 and finally enters the viewing window 30, so that we can see the picture to be photographed through the viewing window 30. When the shutter button (not shown) is pressed, the angle θ is adjusted to 90 degrees, that is, the mirror 124 is perpendicular to the light receiving surface 1262 of the image sensor 126, so that the light 60 can be imaged on the image sensor 126. . The imaging of each image sensor 126 is then processed by the image processor 40 to obtain a panoramic photo. Since the viewing window 30 is disposed on the bottom plate 104 below the panoramic camera 100, the photographer itself does not affect the shooting. It can be understood that the action of the mirror 124 is achieved by pressing the shutter button, thereby adjusting the angle of θ to 90 degrees. For example, the controller can be connected to the motor that drives the mirror 124 by a controller. Shutter button press The controller then controls the operation of the motor to drive the mirror 124 to rotate to an angle θ of 90 degrees. There are many technical means in the prior art for accomplishing this purpose, and details are not described herein again.
在本實施例中，相對之兩個相機模組12之光軸在同一直線上，相鄰之兩個相機模組12之光軸相互垂直。該四個相機模組12中之每個鏡片122分佈於同一圓週上。當然，該四個相機模組12之排佈方式也可以為其他形式，可以為三個相機模組12之鏡片分佈於一圓週上，另外一個相機模組12之鏡片分佈於一與上述圓週之同心圓週上；也可以係該四個相機模組12分佈於一橢圓上。 In this embodiment, the optical axes of the two camera modules 12 are on the same straight line, and the optical axes of the adjacent two camera modules 12 are perpendicular to each other. Each of the four camera modules 12 is distributed on the same circumference. Of course, the four camera modules 12 can be arranged in other forms. The lenses of the three camera modules 12 can be distributed on one circumference, and the lenses of the other camera module 12 are distributed on the circumference. On the concentric circumference, the four camera modules 12 can also be distributed on an ellipse.
請參閱圖5，本發明第二實施例提供之一種全景相機200。該全景相機200包括三個相機模組22及與該三個相機模組22相對應之三個觀景窗23。其中，相鄰之兩個相機模組22之光軸夾角為120度。該每個相機模組22鏡頭之視角均大於120度。當然，該相機模組之數量不局限於本發明實施例中之四個與三個，也可以為兩個、或者多於四個，其可根據相機模組鏡頭之視角之大小來進行選擇。 Referring to FIG. 5, a panoramic camera 200 according to a second embodiment of the present invention is provided. The panoramic camera 200 includes three camera modules 22 and three viewing windows 23 corresponding to the three camera modules 22. The optical axis of the two adjacent camera modules 22 has an angle of 120 degrees. The angle of view of each of the camera modules 22 is greater than 120 degrees. Of course, the number of the camera modules is not limited to four or three in the embodiment of the present invention, and may be two or more than four, which may be selected according to the size of the camera module lens.
相較於先前技術，本發明使用之全景相機100或200通過四個或三個沿著該側壁102之四週排佈之相機模組12或22同時拍攝各自視角下之圖像，然後通過圖像處理器40對該四個或三個圖像進行處理，從而得到全景照片，其省去了複雜之需旋轉單個鏡頭之機械機構，結構簡單且製造難度較低。 Compared with the prior art, the panoramic camera 100 or 200 used in the present invention simultaneously captures images of respective angles of view through four or three camera modules 12 or 22 arranged along the circumference of the side wall 102, and then passes the image. The processor 40 processes the four or three images to obtain a panoramic photo, which eliminates the complicated mechanical mechanism for rotating a single lens, has a simple structure and is less difficult to manufacture.
