测试系统及测试方法Test system and test method

技术领域technical field

本发明涉及本发明涉及一种测试系统及测试方法。具体而言,本发明涉及一种在一光箱中设置多个光板的测试系统及测试方法。The present invention relates to a test system and a test method. Specifically, the present invention relates to a test system and a test method in which a plurality of light panels are arranged in a light box.

背景技术Background technique

一般而言,各种相机上的传感器敏感度不同,即使同一型号的相机也可能有质量不一的情形。此外,相机中的传感器容易受到拍摄场景的光源环境、相机距离拍摄物的远近等因素的影响,而使得不同相机在同一场景所拍摄出来的影像也不一致。因此,相机出厂前的测试尤为重要。In general, sensors on various cameras have different sensitivities, and even cameras of the same model may have varying quality. In addition, the sensor in the camera is easily affected by factors such as the light source environment of the shooting scene, the distance between the camera and the subject, etc., which makes the images captured by different cameras in the same scene inconsistent. Therefore, the test of the camera before leaving the factory is particularly important.

此外,在测试相机模块时,往往需要使用多种光箱分别对应不同测试项目,以配置不同的情境,再通过待测相机模块对此些光箱一一进行拍摄,以分别取得对应各种测试项目的影像信息。然而,此测试方法需在多个不同光箱中设置不同的测试情境,拍摄结果也可能因各个光箱本身的差异,或是待测相机模块在每个光箱的设置位置稍有不同而受影响,导致测试结果不准确。此外,由于待测相机模块需要对应配置不同测试项目的光箱一一进行拍摄,传统的测试方法也实为费时。In addition, when testing a camera module, it is often necessary to use a variety of light boxes corresponding to different test items to configure different scenarios, and then use the camera module to be tested to shoot these light boxes one by one to obtain the corresponding test results. Image information for the item. However, this test method needs to set up different test situations in many different light boxes, and the shooting results may also be affected by the differences of each light box itself, or the slightly different setting position of the camera module under test in each light box. influence, leading to inaccurate test results. In addition, since the camera module to be tested needs to be photographed one by one corresponding to light boxes configured with different test items, the traditional testing method is really time-consuming.

因此,如何改善传统的相机模块测试方法,并提供一种测省时且准确的测试方法及测试系统,成为业界需解决的问题。Therefore, how to improve the traditional camera module testing method and provide a time-saving and accurate testing method and testing system has become a problem to be solved in the industry.

Refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a schematic diagram of a light box according to an embodiment of the present invention. FIG. 2 is a bottom view of the light panel accommodating space of the light box shown in FIG. 1 . The test system 100 includes a light box 120 , a plurality of light boards 220 , 240 , 260 and a load base 122 . Wherein, the light panels 220 , 240 , 260 are respectively arranged in the light box 120 , and the light panels 220 , 240 , 260 are respectively located in different depths in the light box 120 . The carrying bottom 122 is used to fixedly carry a lens module to be tested 140, and make the lens module to be tested 140 face the light box 120 and the light boards 220, 240, 260. The distances are not the same. Wherein, when the lens module 140 under test captures the first image frame, the first image frame includes images of the light panels 220 , 240 , 260 .

更具体而言,如图1所示,在一实施例中,光板220、240、260放置在光板容置空间200中,光板容置空间200的顶部即为光箱120的顶部124,而待测相机模块140可放置在底部122。然而,待测相机模块140与光板容置空间200的摆放方式并不局限于此,在另一实施例中,待测相机模块140仅需放置在能够拍摄到各光板220、240、260的位置即可。由此,当待测镜头模块140往光板容置空间200拍摄影像画面时,其拍摄到的影像画面可同时包含光板220、240、260的影像。More specifically, as shown in FIG. 1 , in one embodiment, the light panels 220, 240, 260 are placed in the light panel accommodating space 200, and the top of the light panel accommodating space 200 is the top 124 of the light box 120, and to be A camera module 140 may be placed on the bottom 122 . However, the arrangement of the camera module 140 to be tested and the light panel accommodating space 200 is not limited thereto.

接着,回到图4的步骤S420。在步骤S420中,依据第二影像画面,计算一景深信息,并将影像景深信息与一已知景深信息相比较,以取得一近景校正值、一中景校正值及一远景校正值。Next, return to step S420 in FIG. 4 . In step S420 , according to the second image frame, a depth information is calculated, and the image depth information is compared with known depth information to obtain a close-range correction value, a middle-ground correction value, and a far-field correction value.

在一实施例中,待测镜头模块140通过其所包含的多个摄像镜头分别拍摄光板220、240、260,使各个摄像镜头各自取得一第二影像画面,并以处理单元(未绘示),依据此些第二影像画面中的至少二影像画面中的多个定位点与待测镜头模块140之间的夹角,以计算一影像景深信息。其中,影像景深信息包含一远景景深信息、一中景景深信息、一近景景深信息。In one embodiment, the lens module 140 to be tested takes pictures of the light panels 220, 240, and 260 through a plurality of camera lenses included in it, so that each camera lens obtains a second image frame, and uses a processing unit (not shown) An image depth information is calculated according to the included angles between a plurality of positioning points in at least two image frames of the second image frames and the lens module 140 to be tested. Wherein, the image depth information includes far-field depth information, middle-field depth information, and near-field depth information.

在另一实施例中,待测镜头模块140具有四个摄像镜头,此四个摄像镜头都分别拍摄所有光板220、240、260,以各自取得一第二影像画面。由于各光板220、240、260上都至少包含有定位图500及解析图510,因此每个四个摄像镜头所拍摄的第二影像画面,也都包含有定位图500及一解析图510。处理单元可通过此四个摄像镜头分别拍摄第二影像画面中,任选至少两张第二影像画面中的定位图500以计算出一影像深度信息。In another embodiment, the lens module 140 under test has four camera lenses, and the four camera lenses capture all the light panels 220 , 240 , and 260 respectively to obtain a second image frame. Since each light board 220 , 240 , 260 at least includes a positioning map 500 and an analysis map 510 , the second image frame captured by each of the four camera lenses also includes a positioning map 500 and an analysis map 510 . The processing unit can respectively capture at least two positioning maps 500 in the second image frame through the four camera lenses to calculate an image depth information.

以下说明产生景深信息的具体实施方式。请参阅图6~8。图6为图4的步骤S420的子步骤流程图。图7为根据本发明一实施例的景深校正方法的示意图。图8为根据本发明另一实施例的景深校正方法的示意图。The specific implementation manner of generating the depth information is described below. Please refer to Figures 6-8. FIG. 6 is a flowchart of sub-steps of step S420 in FIG. 4 . FIG. 7 is a schematic diagram of a depth-of-field correction method according to an embodiment of the present invention. FIG. 8 is a schematic diagram of a depth-of-field correction method according to another embodiment of the present invention.

在步骤S421中,处理单元由各个第二影像画面中取得远景定位点、中景定位点及近景定位点的坐标位置。In step S421 , the processing unit obtains the coordinate positions of the far view anchor point, the middle view anchor point and the near view anchor point from each second image frame.

举例而言,如图7所示,定位图500a~500d系为分别属在四张第二影像画面中的定位图。定位图500a~500d中,饼图样代表远景定位点,方形图样代表中景定位点,三角形图样代表近景定位点。在一实施例中,处理单元选择以所有第二影像画面的定位图500a~500d进行运算,并由各个第二影像画面中取得远景定位点、中景定位点及近景定位点的坐标位置。应可理解的,一般而言,选择用以进行运算的第二影像画面数越多,则在后续步骤中,景深深度计算的精准度越高。For example, as shown in FIG. 7 , the positioning maps 500 a - 500 d are positioning maps respectively belonging to four second image frames. In the positioning maps 500 a - 500 d , the pie pattern represents the long-range positioning point, the square pattern represents the middle-ground positioning point, and the triangle pattern represents the near-view positioning point. In one embodiment, the processing unit selects all the positioning diagrams 500 a - 500 d of the second image frame for calculation, and obtains the coordinate positions of the distant anchor point, the middle-ground anchor point and the near-view anchor point from each second image frame. It should be understood that, generally speaking, the more the number of second image frames selected for calculation, the higher the accuracy of the depth of field calculation in the subsequent steps.

在步骤S422中,处理单元计算至少二第二影像画面中的多个定位点与待测镜头模块140之间的夹角,以得到一影像景深信息。其中,影像景深信息包含远景景深信息、中景景深信息、近景景深信息。In step S422 , the processing unit calculates angles between a plurality of positioning points in at least two second image frames and the lens module 140 to be tested to obtain an image depth information. Wherein, the image depth-of-field information includes far-field depth-of-field information, middle-field depth-of-field information, and near-field depth-of-field information.

举例而言,如图8所示,基在摄影成像概念而言,以分别两个拍摄位置拍摄物体时,将所摄得的两张画面810、820,经迭合产生画面830后,距离摄像镜头较远的物体的两个成像811、821与一定点831的夹角x1较小,距离摄像镜头较远的物体的两个成像812、822与定点831的夹角x2较大。据此,可通过此成像特性,将多个以不同拍摄位置所摄得的多张画面进行重合,并依据迭合画面中同一物体的多个成像与摄像镜头或某一定点的夹角,以辨别物体在影像画面中系为远、中、近景的关系,以计算出影像景深信息。For example, as shown in FIG. 8 , based on the concept of photography and imaging, when shooting an object at two shooting positions respectively, the two captured pictures 810 and 820 are superimposed to generate a picture 830, and the distance camera The included angle x1 between the two images 811, 821 of the object farther away from the camera lens and the fixed point 831 is smaller, and the included angle x2 between the two images 812, 822 of the object farther from the camera lens and the fixed point 831 is larger. Accordingly, through this imaging characteristic, a plurality of pictures captured by different shooting positions can be superimposed, and according to the included angle between multiple imaging of the same object in the superimposed picture and the camera lens or a fixed point, the Distinguish the relationship between objects in the image frame as far, middle, and near, so as to calculate the image depth information.

在一实施例中,如图7所示,定位图500a~500d为此四个摄像镜头分别拍摄第二影像画面中的定位图。处理单元可依据定位图500a~500d中的各个定位点坐标位置,将定位图500a~500d迭合为一合并定位图500e。基于前述的任两张第二影像中各自的远景定位点与待测镜头模块140(或任一定点)的夹角较小,任两张第二影像中各自的近景定位点与待测镜头模块140的夹角较大的概念,可由合并定位图500e得知各种定位点距离待测镜头模块140的远近关系。In one embodiment, as shown in FIG. 7 , the positioning maps 500 a - 500 d are the positioning maps in the second image frame respectively captured by the four camera lenses. The processing unit may superimpose the positioning maps 500a-500d into a merged positioning map 500e according to the coordinate positions of each positioning point in the positioning maps 500a-500d. Based on the angles between the respective long-range anchor points in the aforementioned any two second images and the lens module 140 (or any fixed point) to be tested are relatively small, the respective close-range anchor points in any two second images and the lens module to be tested Based on the concept that the included angle of 140 is relatively large, the distance relationship between various positioning points and the lens module 140 to be tested can be known from the combined positioning diagram 500e.

例如,合并定位图500e中,饼图样的定位点较为密集,且任两个饼图样的定位点与待测镜头模块140(或任一定点)的夹角较小,密集度较高,故可判断此些饼图样的定位点代表远景定位点;方形图样的定位点的密集程度次之,故可判断此些方形图样的定位点代表中景定位点;三角形图样的定位点最为松散,且任两个三角形图样的定位点与待测镜头模块140的夹角较大,密集度最低,因此可判断三角形图样的定位点代表近景定位点。For example, in the merged positioning map 500e, the positioning points of the pie pattern are relatively dense, and the angle between any two positioning points of the pie pattern and the lens module 140 (or any fixed point) to be tested is relatively small, and the density is relatively high, so it can be It is judged that the anchor points of these pie patterns represent the distant anchor points; the anchor points of the square pattern are less intensive, so it can be judged that the anchor points of these square patterns represent the middle ground anchor points; the anchor points of the triangle pattern are the loosest, and any The angles between the anchor points of the two triangle patterns and the lens module 140 to be tested are relatively large, and the density is the lowest. Therefore, it can be determined that the anchor points of the triangle patterns represent close-range anchor points.

据此,可通过多个第二影像中的定位图重合后,依据定位点的密集程度或是两定位点与镜头的夹角,以判别各定位点系属在画面中的远景、中景或近景。Accordingly, after overlapping the positioning maps in multiple second images, it can be determined whether each positioning point belongs to the distant view, middle ground or close shot.

在步骤S423中,处理单元将影像景深信息与一已知景深信息相比较,以取得一近景校正值、一中景校正值及一远景校正值。In step S423 , the processing unit compares the image depth information with known depth information to obtain a close-range correction value, a middle-ground correction value, and a far-field correction value.

举例而言,如前述对应图3所叙及的段落,光板220、240、260与待测镜头模块140的实际距离为已知,可作为已知景深信息。因此,处理单元可将在步骤S422中所取得的影像景深信息与已知景深信息相比较,即可计算出近景校正值、中景校正值及远景校正值。For example, as mentioned above in the paragraph corresponding to FIG. 3 , the actual distances between the optical panels 220 , 240 , 260 and the lens module 140 to be tested are known, which can be used as the known depth of field information. Therefore, the processing unit can compare the image depth information obtained in step S422 with the known depth information, and then calculate the close-range correction value, middle-ground correction value and distant-view correction value.

在步骤S424中,储存器(未绘示)用以储存校正参数,校正参数包含近景校正值、中景校正值及远景校正值。In step S424 , the memory (not shown) is used to store the correction parameters, and the correction parameters include a close-range correction value, a middle-ground correction value, and a distant-view correction value.

其中,处理单元及储存器可以放置在光箱120内或是独立置在光箱120外,与待测镜头模块140电性耦接。处理单元可以由体积电路如微控制单元(microcontroller)、微处理器(microprocessor)、数字信号处理器(digital signalprocessor)、特殊应用集成电路(application specific integrated circuit,ASIC)或一逻辑电路来实施。此外,储存器用以储存各种数据,例如是内存、硬盘、随身碟记忆卡等。Wherein, the processing unit and the storage can be placed inside the light box 120 or independently placed outside the light box 120 , and are electrically coupled with the lens module 140 to be tested. The processing unit may be implemented by a bulk circuit such as a microcontroller, a microprocessor, a digital signal processor, an application specific integrated circuit (ASIC), or a logic circuit. In addition, the storage is used to store various data, such as internal memory, hard disk, flash memory card and so on.

接着,回到图4的步骤S430。在步骤S430中,将远景景深信息、中景景深信息、近景景深信息通过近景校正值、中景校正值及远景校正值进行校正,以输出一全景深影像,全景深影像包含校正后的此些第二影像。Next, return to step S430 in FIG. 4 . In step S430, correct the far-field depth information, middle-field depth-of-field information, and near-field depth-of-field information by using the near-field correction value, mid-field correction value, and long-field correction value to output a full-depth image, which includes the corrected Second image.

在步骤S440中,处理单元依据全景深影像中的第二影像中的解析图,以计算全景深影像的清晰度,并将校正后的第二影像进行互补,以产生一互补全景深影像,并计算互补全景深影像的一景深分布图。其中,景深分布图可以例如为互补全景深影像的对应景深直方图或其他以数值方式呈现的分布图。In step S440, the processing unit calculates the resolution of the full depth image according to the analysis map in the second image of the full depth image, and complements the corrected second image to generate a complementary full depth image, and Computing a depth distribution map of the complementary full depth image. Wherein, the depth-of-field distribution map may be, for example, a corresponding depth-of-field histogram of the complementary panoramic depth image or other distribution maps presented in a numerical manner.

在一实施例中,处理单元可以利用至少两张校正后的第二影像进行互补,互补的方式可以为投票法、计算像素平均值或其他可将影像进行互相补偿的算法。举例而言,处理单元利用三张校正后的第二影像进行互补,且此三张校正后的第二影像中都具有一相同的对象;若此对象只有在两张校正后的第二影像中的位置为相同,则以此两张校正后的第二影像中的对象位置为准,将另一张校正后的第二影像中的对象位置,调整为与此两张校正后的第二影像相同。In one embodiment, the processing unit may use at least two corrected second images to perform complementation, and the complementation method may be voting method, pixel average calculation, or other algorithms that can compensate images for each other. For example, the processing unit uses three rectified second images for complementation, and the three rectified second images all have a same object; if the object is only present in the two rectified second images If the positions are the same, then the object positions in the two corrected second images shall prevail, and the object position in the other corrected second image shall be adjusted to be the same as the object position in the two corrected second images same.

在步骤S450中,处理单元将互补全景深影像中的远景景深信息及中景景深信息进行一模糊化处理,以产生一合成分段景深图。In step S450 , the processing unit performs a blurring process on the distant field depth information and the middle field depth information in the complementary full depth image to generate a composite segmented depth map.

通过此方式,可使输出的合成分段景深图中,具有近景景深信息的对象更为突显,而其他画面部分系为模糊,并通过人眼或处理单元判断是否合成分段景深图中的近景部分正确,在一实施例中,判断的方式是将合成分段景深图中的近景部分与已知的实际近景部分进行比对,以判断是否合成分段景深图与实际环境的误差小于一误差门坎值。例如,分段景深图中的近景部分为一颗篮球,且已知的实际近景部分确实为一颗篮球,则判断合成分段景深图与实际环境的误差小于一误差门坎值。由此使用者可得知经由互补全景深影像所产生的合成分段景深图,其与实际环境的误差是否在可接受的范围内。In this way, the objects with near-field depth information in the output composite segmented depth-of-field map can be more prominent, while other parts of the picture are blurred, and the human eye or processing unit can judge whether to synthesize the close-up in the segmented depth-of-field map Partially correct. In one embodiment, the way of judging is to compare the foreground part in the synthesized segmented depth map with the known actual foreground part to determine whether the error between the synthesized segmented depth map and the actual environment is less than one error Threshold value. For example, if the foreground part in the segmented depth map is a basketball, and the known actual foreground part is indeed a basketball, it is determined that the error between the synthesized segmented depth map and the actual environment is less than an error threshold. In this way, the user can know whether the error between the synthetic segmented depth map generated by the complementary full depth image and the actual environment is within an acceptable range.

在步骤S460中,处理单元将已知景深信息与合成分段景深图中之一远景画面、一中景画面及一近景画面进行比对,以产生一分析结果,且利用显示器(图未示)以显示分析结果。由此,可判断经由校正、互补等步骤而产生的合成分段景深图是否在远景画面、中景画面及近景画面的表现正确且清晰,并将分析结果显示出来。In step S460, the processing unit compares the known depth information with a long-range frame, a mid-range frame, and a close-range frame in the synthesized segmental depth map to generate an analysis result, and utilizes a display (not shown) to display the analysis results. In this way, it can be judged whether the composite segmental depth map generated through the steps of correction and complementation is correct and clear in the long-range picture, middle-ground picture and close-range picture, and the analysis result is displayed.

通过上述的测试系统及测试方法,本发明可通过包含多重景深的单一光箱内,撷取一张画面即可取得多种不同深度信息,并可利用此些深度信息以检测待测像机模块在远、中、近景的摄像表现,并可应用此些深度信息以对待测像机模块进行校正。Through the above-mentioned testing system and testing method, the present invention can obtain a variety of different depth information by capturing a frame in a single light box containing multiple depths of field, and can use this depth information to detect the camera module to be tested The camera performance in the far, medium and close range, and can use this depth information to correct the camera module to be measured.
