Where certain terms are used throughout the description and claims to refer to particular components, those skilled in the art will appreciate that manufacturers may refer to the same components by different names. In the present specification and claims, the difference in name is not used as a means for distinguishing between components, but a difference in function of a component is used as a reference for distinguishing between components. The present invention will be described in detail below with reference to the accompanying drawings and examples.
Fig. 1 is a flowchart of a method for testing an included angle between two cameras according to an embodiment of the present invention, where the method is based on two cameras, a range-increasing lens and a test picture, the range-increasing lens is disposed between the two cameras and the test picture, and the two cameras include a first camera and a second camera. It should be noted that the method of the present invention is not limited to the flow sequence shown in fig. 1 if the results are substantially the same. As shown in fig. 1, the method comprises the steps of:
step S101: and adjusting the center of the first camera, the center of the distance-increasing lens and the center of the test picture to be on the same straight line.
In step S101, the test picture is preferably an ISO12233 resolution test card (ISO12233Chart), and the center of the test picture is at the center of the central focus area of the ISO12233 Chart. The central focusing area is concentric circles with two different frequencies to assist focusing.
The operation of adjusting the center of the first camera, the center of the range extender and the center of the test picture on a straight line is specifically as follows: fixing a test picture; arranging a laser device on the range-increasing lens and controlling the laser device to emit laser to the test picture from the center of the range-increasing lens; adjusting the position of the distance-increasing lens to ensure that the laser emitted by the laser device is opposite to the center of the test picture and then fixing the distance-increasing lens; adjusting the laser device and controlling the laser device to emit laser to the first camera from the center of the range extender; and adjusting the position of the first camera so that the laser emitted by the laser device is opposite to the center of the first camera.
Preferably, the laser device and the range-increasing mirror have the same size, wherein the laser device and the range-increasing mirror are arranged concentrically when the laser device is arranged on the range-increasing mirror.
Preferably, the edge of the laser device is provided with a clamping position, and the clamping position of the laser device is clamped with the distance-increasing mirror so as to fix the laser device on the distance-increasing mirror.
Step S102: focusing the center of the test picture to be shot and shooting the test picture, and determining the coordinate value of the first imaging point of the center of the shot test picture.
In step S102, after the center of the first camera, the center of the range finder and the center of the test picture are ensured to be aligned, the mobile terminal focuses the center of the test picture and photographs the test picture, and then determines a first imaging point coordinate value (x1, y1) of the center of the test picture in the photographed test picture.
Referring to fig. 2, fig. 2 is a schematic focusing reference diagram of the first camera and the test picture. As shown in fig. 2, the mobile terminal 11 is provided with dual cameras including a first camera C1 and a second camera C2. The range-increasing mirror 12 is disposed between the dual cameras 111 and the test picture 13. Wherein, the center of the first camera C1, the center of the range-increasing lens 12 and the center of the test picture 13 (i.e. at O1) are on a straight line, and the center of the rectangular focusing frame A1B1C1D1 of the mobile terminal coincides with the center of the test picture (i.e. at O1).
Preferably, after the center of the first camera, the center of the range-increasing lens and the center of the test picture are ensured to be on a straight line, and the mobile terminal focuses on the center of the test picture, the method further comprises the following steps: judging whether the focusing operation on the center of the test picture is successful or not; if the focusing operation is successful, continuing to execute the shooting operation; and if the focusing operation is unsuccessful, displaying prompt information of 'included angle test failure'.
Those skilled in the art can understand that the coordinate value of the imaging point of the center of the test picture taken by the mobile terminal after the focusing operation fails is inaccurate, so that when the focusing operation fails, subsequent tests do not need to be performed continuously, that is, the mobile terminal can be determined to be a defective product and not meet the factory requirements.
Step S103: and adjusting the center of the second camera, the center of the distance-increasing lens and the center of the test picture to be on the same straight line.
In step S103, the step of adjusting the center of the second camera, the center of the range-increasing mirror, and the center of the test picture on a straight line includes: and controlling the second camera to move a preset distance towards the first camera along a direction perpendicular to a connecting line of the center of the first camera and the center of the range extender and towards the first camera, wherein the preset distance is a standard distance between the center of the first camera and the center of the second camera in the design process of the double cameras.
That is to say, the mobile terminal moves horizontally for a predetermined distance along a direction perpendicular to a connecting line of the center of the first camera and the center of the range-extender, so that the second camera is located at a position where the first camera takes a picture of the test picture.
Step S104: and after focusing and shooting the center of the test picture to be shot, determining a second imaging point coordinate value of the center of the shot test picture.
In step S104, after the center of the second camera, the center of the range finder and the center of the test picture are aligned, the mobile terminal focuses the center of the test picture and photographs the test picture, and then finds a second imaging point coordinate value (x2, y2) of the center of the test picture in the photographed test picture.
Referring to fig. 3, fig. 3 is a focusing reference diagram of the second camera and the test picture. As shown in fig. 3, the center of the second camera C2, the center of the range-increasing mirror 12 and the center of the test picture 13 (i.e., at O1) are on a straight line, and the center of the rectangular focusing frame A1B1C1D1 of the mobile terminal coincides with the center of the test picture (i.e., at O1). And d is the standard distance between the center of the first camera and the center of the second camera in the design process of the double cameras.
Preferably, after the center of the second camera, the center of the range-increasing lens and the center of the test picture are ensured to be on the same straight line, and the mobile terminal focuses on the center of the test picture, the method further comprises the following steps: judging whether the focusing operation on the center of the test picture is successful or not; if the focusing operation is successful, continuing to execute the shooting operation; and if the focusing operation is unsuccessful, displaying prompt information of 'included angle test failure'.
Step S105: and judging whether the included angle between the first camera and the second camera meets the factory requirements or not according to the coordinate values of the first imaging point and the second imaging point.
In step S105, when the resolutions of the first camera and the second camera are equivalent and have equivalent maximum pixel sizes, comparing the first imaging point coordinate value and the second imaging point coordinate value: if the coordinate value of the first imaging point is equal to the coordinate value of the second imaging point, the center of the shot test point is not displaced, namely the first camera and the second camera are not deviated, and the included angle is zero; if the coordinate value of the first imaging point is not equal to the coordinate value of the second imaging point, the center of the shot test point is displaced, that is, the first camera and the second camera are offset, and the included angle is not zero.
Referring to fig. 4, fig. 4 is a schematic position diagram of the first imaging point coordinate value and the second imaging point coordinate value. When the first imaging point coordinate value is not equal to the second imaging point coordinate value, the operation of judging whether the included angle between the first camera and the second camera meets the factory requirement according to the first imaging point coordinate value and the second imaging point coordinate value specifically comprises: acquiring a linear distance between the coordinate values of the first imaging point and the second imaging point; judging whether the straight line distance is smaller than a preset threshold value or not; and if the linear distance is smaller than the preset threshold value, judging that the included angle between the first camera and the second camera meets the factory requirement.
Specifically, when the first imaging point coordinate value (x1, y1) and the second imaging point coordinate value (x2, y2),
the straight-line distance d between the first imaging point coordinate value and the second imaging point coordinate value satisfies the following formula:
d2＝(x2-x1)2+(y2-y1)2。
after calculating the linear distance d between the coordinate values of the first imaging point and the second imaging point, judging whether the linear distance d is smaller than a preset threshold value S: if the linear distance d is smaller than the preset threshold value S, the deviation of the first camera and the second camera is within an acceptable range, and the included angle meets the factory requirement; if the straight-line distance d is larger than or equal to the preset threshold value S, the deviation between the first camera and the second camera is large, and the included angle test is not met.

As shown in fig. 5, the testing device includes a test picture 21, a distance-increasing lens 22 and a processor 23, and the testing device is used for testing the included angle of the dual cameras 24, wherein the dual cameras 24 include a first camera 241 and a second camera 242.

In particular, the laser device 26 and the range mirror 22 have the same size, wherein the laser device 26 and the range mirror 22 are arranged concentrically when the laser device 26 is arranged on the range mirror 22. When the laser device 26 works, the processor 23 is matched to realize that the operations of the center of the first camera 241, the center of the distance-increasing mirror 22 and the center of the test picture 21 on one straight line are specifically as follows: fixing a test picture 21; arranging a laser device 26 on the range-increasing lens 22 so that the laser device 26 emits laser to the test picture 21 from the center of the range-increasing lens 22; adjusting the position of the distance-increasing lens 22 to ensure that the laser emitted by the laser device 26 is just opposite to the center of the test picture 21 and then fixing the distance-increasing lens 22; adjusting the laser device 26 so that the laser device 26 emits laser light from the center of the range-extending mirror 22 to the first camera 241; the processor 23 adjusts the position of the first camera 241 so that the laser light emitted from the laser device 26 is directed toward the center of the first camera 241.
The processor 23 performs the operation of adjusting the center of the second camera 242, the center of the distance-increasing mirror 22 and the center of the test picture 21 on a straight line, including: the processor 23 controls the second camera 242 to move a predetermined distance toward the first camera 241 in a direction perpendicular to a line connecting the center of the first camera 241 and the center of the range-finding mirror 22, wherein the predetermined distance is a standard distance between the center of the first camera and the center of the second camera in the process of the dual-camera design.
The operation of the processor 23 for judging whether the included angle between the first camera 241 and the second camera 242 meets the factory requirement according to the first imaging point coordinate value and the second imaging point coordinate value includes: the processor 23 obtains a linear distance between the coordinate values of the first imaging point and the coordinate values of the second imaging point; judging whether the straight line distance is smaller than a preset threshold value or not; if the linear distance is smaller than the predetermined threshold, it is determined that the included angle between the first camera 241 and the second camera 242 meets the factory requirements.
Specifically, when the first imaging point coordinate value is (x1, y1) and the second imaging point coordinate value is (x2, y2), the straight-line distance d between the first imaging point coordinate value and the second imaging point coordinate value satisfies the following formula:
d2＝(x2-x1)2+(y2-y1)2。
and after the linear distance d between the coordinate values of the first imaging point and the second imaging point is calculated, judging whether the linear distance d is smaller than a preset threshold value S. If the linear distance d is smaller than the preset threshold value S, the deviation of the first camera and the second camera is within an acceptable range, and the included angle meets the factory requirement; if the straight-line distance d is larger than or equal to the preset threshold value S, the deviation between the first camera and the second camera is large, and the included angle test is not met.
