Frame 11 folds or is unfolded and adjusts the angle of first support 11 and pedestal 13.In first support 11 and the junction of pedestal 13
Equipped with locking device, when the rotation of first support 11 is to pedestal 13 at an angle, the locking device is tightened so that first
Frame 11 keeps the certain angle to be fixed on pedestal 13.Preferably, first support 11 can be in the range of 0 ° -90 ° along pedestal 13
Axial-rotation, and first support 11 rotation to pedestal 13 be in 90 ° when, tighten the locking device so that first support 11
Holding is perpendicularly fixed at pedestal 13.
In the axial other end of pedestal 13, there are two installation grooves for setting, and the rotation of second support 12 is installed on two peaces
Between dress groove so that second support 12 can be around axial-rotation of two installation grooves along pedestal 13, thus by second support 12
It folds or is unfolded and adjusts second support 12 and the angle of pedestal 13.It is similary with the junction of pedestal 13 in second support 12
Equipped with locking device, when the rotation of second support 12 is to pedestal 13 at an angle, the locking device is tightened so that second
Frame 12 keeps the certain angle to be fixed on pedestal 13.Preferably, second support 12 can be in the range of 0 ° -90 ° along pedestal 13
Axial-rotation, and second support 12 rotation to pedestal 13 be in 90 ° when, tighten the locking device so that second support 12
Holding is perpendicularly fixed at pedestal 13.
Further, accommodating chamber is equipped in pedestal 13, when first support 11, second support 12 fold into pedestal 13, is held
Receive first support 11, second support 12.Accommodating chamber could be provided as only accommodating first support 11 or only accommodate second support 12,
Or first support 11, second support 12 are accommodated simultaneously.For example, when accommodating chamber only accommodates second support 12,13 inside of pedestal is dug
Sky extends to form accommodating chamber, the shape of accommodating chamber and second from 12 one end of second support of pedestal 13 to 11 one end of first support
The exterior contour of stent 12 is consistent, and when second support 12 folds into pedestal 13, second support 12 is contained in the receiving completely
Intracavitary.For another example, it when accommodating chamber only accommodates first support 11, will be hollowed out inside pedestal 13, by 11 one end of first support of pedestal 13
Accommodating chamber is extended to form to 12 one end of second support, the shape of accommodating chamber is consistent with the exterior contour of first support 11, when
When one stent 11 folds into pedestal 13, first support 11 is contained in completely in the accommodating chamber.
The one end of first support 11 far from pedestal 13 is equipped with test board 17, and the first sliding rail 14 is arranged in first support 11,
Test board 17 can be moved up and down along the first sliding rail 14, so as to adjust height of the test board 17 apart from pedestal 13.It is set on test board 17
There is crisscross grid, for calibrating the position for the test card for being attached at test board 17.The axial both ends extension of test board 17
There is minute surface 18, minute surface 18 is set with test board 17 in an angle.According to the distance between camera and test board 17, can adjust
Whether suitable the angle angle that minute surface 18 is in test board 17 is convenient to observation camera shooting picture in minute surface 18.
The one end of second support 12 far from pedestal 13 is equipped with geometrical clamp 19, geometrical clamp 19 for clamp smart mobile phone so as to
Fixing camera.The second sliding rail 15 is arranged in second support 12, geometrical clamp 19 can be moved up and down along the first sliding rail 14, so as to adjust
Height of the camera apart from pedestal 13.
Third sliding rail 16 is equipped in pedestal 13, it is preferable that third sliding rail 16 is set in the accommodating chamber of pedestal 13, second support
12 can move close to along third sliding rail 16 or far from first support 11, so as to adjust the distance between camera and test board 17.
In the present embodiment, first support 11, second support 12 along 13 axial-rotation of pedestal and are locked so that first support
11st, second support 12 is perpendicularly fixed on pedestal 13, and test board 17 is moved along the first sliding rail 14 to adjust 17 distance of test board
The height of pedestal 13 moves geometrical clamp 19 to adjust height of the camera apart from pedestal 13 along the second sliding rail 15, by second
Frame 12 moves, closer or far from first support 11, to adjust the distance between test board 17 and camera, most along third sliding rail 16
Eventually so that the center of the optical axis center alignment test board 17 of camera, test board 17 are in the shooting picture of camera, test
Test card on plate 17 is full of the 100% of preview screen, after frame stabilization, takes pictures and preserves.
Camera testing device 100 further includes lamp box, and test board 17 is positioned over before lamp box, adjusts light source.
Camera testing device 100 is further included analysis shows that shielding, analysis shows that screen receives the shooting picture of camera, use
Test result is calculated and be shown in IMATEST softwares.
With reference to figure 3, the Camera Test method of the camera testing device of the smart mobile phone based on the present invention is including following
Step：
(1) according to test needs, test card (such as colour atla, distortion block) is attached on test board, the net on test board
Lattice ensure that the position of test card is accurate；
(2) rotary expansion first support makes it that test board are installed on first support perpendicular to pedestal；
