以下结合附图对本实用新型的技术方案作进一步描述。Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
如图1所示的一种手持三维扫描装置工作结构示意图，包括：手持设备本体2(此例中可以例如是手机或平板电脑)，手持设备本体2的背面设有第一摄像头5和照明光源4。在照明光源4的出光窗上贴有散斑底片3，以便将散斑底片3上的散斑图像投影到被测物体7上，所述第一摄像头5获取由被测物体7表面形貌调制的散斑图像(参见图2)。手持设备本体2通过第一摄像头5采集由被测物体7表面形貌调制的散斑图像，并根据采集到的信息获得被测物体7的三维形貌信息。手持设备本体2上还可以设置第二摄像头6或更多的摄像头，由此获取更多的被测物体7的三维形貌信息，从而提高三维图像的精度。上述多个摄像头中至少一个是彩色摄像头，其余的黑白摄像头。采用更多的黑白摄像头可以改善三维图像的精度并且降低成本。A schematic diagram of the working structure of a hand-held three-dimensional scanning device as shown in Figure 1, comprising: a hand-held device body 2 (such as a mobile phone or a tablet computer in this example), the back of the hand-held device body 2 is provided with a first camera 5 and an illumination source 4. A speckle film 3 is pasted on the light exit window of the illumination source 4, so as to project the speckle image on the speckle film 3 onto the measured object 7, and the first camera 5 acquires speckle image (see Figure 2). The handheld device body 2 collects the speckle image modulated by the surface topography of the measured object 7 through the first camera 5, and obtains the three-dimensional topography information of the measured object 7 according to the collected information. The handheld device body 2 can also be provided with a second camera 6 or more cameras, thereby obtaining more three-dimensional shape information of the measured object 7, thereby improving the accuracy of the three-dimensional image. At least one of the plurality of cameras is a color camera, and the rest are black and white cameras. Using more monochrome cameras can improve the accuracy of 3D images and reduce costs.
手持设备本体2上还可设置第二光源1和时序控制模块(未示出)。时序控制模块交替地发出第一周期信号和第二周期信号。在第一周期内，手持设备本体2根据第一周期信号点亮照明光源4以照亮散斑底片3在被测物体7上投影散斑图像，同时控制第一摄像头5(任选地和第二摄像头6)采集被测物体7上由被测物体7表面形貌调制的散斑图像，并据此生成被测物体7的三维图像数据。在第二周期内，手持设备本体2根据第二周期信号关闭照明光源4，然后点亮第二光源1，将第二光源1发出的白光照射到被测物体7上，同时控制第一摄像头5或第二摄像头6采集被测物体7的彩色纹理信息。手持设备本体通过计算将在第一周期获得的三维图像数据与第二周期获得彩色纹理信息匹配，从而获得被测物体7的彩色三维图像。A second light source 1 and a timing control module (not shown) can also be arranged on the handheld device body 2 . The timing control module sends out the first period signal and the second period signal alternately. In the first period, the handheld device body 2 lights up the illumination light source 4 according to the first period signal to illuminate the speckle film 3 to project a speckle image on the measured object 7, and at the same time controls the first camera 5 (optionally with the second The second camera 6) collects speckle images modulated by the surface topography of the measured object 7 on the measured object 7, and generates three-dimensional image data of the measured object 7 accordingly. In the second period, the handheld device body 2 turns off the illumination light source 4 according to the second period signal, then lights up the second light source 1, and illuminates the white light emitted by the second light source 1 onto the measured object 7, while controlling the first camera 5 Or the second camera 6 collects the color texture information of the measured object 7 . The handheld device body matches the three-dimensional image data obtained in the first cycle with the color texture information obtained in the second cycle through calculation, so as to obtain a color three-dimensional image of the measured object 7 .
申请人已经注意到现有的部分移动终端的背面设有两个摄像头，可以通过该两个摄像头获得两维图像。因此，在本申请的另一优选实施例中，一种移动终端(例如是手机、PDA或平板电脑等)，包括：第三摄像头、第四摄像头，以及第三照明光源、第四照明光源，和控制开关。其中，第三照明光源为闪光灯，在第四照明光源的出光窗上贴有结构光底片(例如散斑底片)，以便将结构光底片上的结构光图像投影到被测物体上。The applicant has noticed that there are two cameras on the back of some existing mobile terminals, and two-dimensional images can be obtained through the two cameras. Therefore, in another preferred embodiment of the present application, a mobile terminal (such as a mobile phone, a PDA or a tablet computer, etc.) includes: a third camera, a fourth camera, a third lighting source, a fourth lighting source, and control switches. Wherein, the third illumination source is a flashlight, and a structured light film (such as a speckle film) is pasted on the light exit window of the fourth illumination source, so as to project the structured light image on the structured light film onto the measured object.
移动终端的两个摄像头具有两种工作模式，控制开关用于控制移动终端在这两种工作模式下拍摄。在第一种工作模式中，第四照明光源处于关闭状态，第三及第四摄像头获取被测物体的普通二维图像。在第二种工作模式中，点亮第四照明光源，所述第三及第四摄像头获取由被测物体表面形貌调制的结构光图像(例如散斑图像)。移动终端通过第三及第四摄像头采集由被测物体表面形貌调制的散斑图像，并根据采集到的信息获得被测物体的三维形貌信息。通过该优选实施例，可以将具有两个摄像头的移动终端升级为获得三维图像并进行三维测量的移动终端，而且升级成本低。The two cameras of the mobile terminal have two working modes, and the control switch is used to control the mobile terminal to shoot in the two working modes. In the first working mode, the fourth illumination source is turned off, and the third and fourth cameras acquire ordinary two-dimensional images of the measured object. In the second working mode, the fourth illumination light source is turned on, and the third and fourth cameras acquire structured light images (such as speckle images) modulated by the surface topography of the measured object. The mobile terminal collects speckle images modulated by the surface topography of the measured object through the third and fourth cameras, and obtains three-dimensional topography information of the measured object according to the collected information. Through this preferred embodiment, a mobile terminal with two cameras can be upgraded to a mobile terminal that obtains three-dimensional images and performs three-dimensional measurement, and the upgrade cost is low.
所述摄像头经设置以获取被测物体表面的由被测物体表面形貌调制的散斑图像，所述数据处理模块经设置以处理来自所述摄像头的由被测物体表面形貌调制的散斑图像并得到被测物体的三维图像。The camera is configured to acquire speckle images on the surface of the measured object modulated by the surface topography of the measured object, and the data processing module is configured to process speckle images from the camera modulated by the surface topography of the measured object image and obtain a three-dimensional image of the measured object.
