Detailed Description
The embodiment of the invention provides a testing device and a testing system, which are used for enabling the testing device to test cameras with different specifications so as to improve the testing efficiency.
As shown in fig. 1, the embodiment of the invention provides a schematic diagram of a test scenario. In this test scenario, a test system is involved that can be used to test the camera to identify if the camera is a satisfactory one.
Referring to fig. 1, the test system includes: test device, camera 10 and test box 15.
Specific implementations of the test device reference may be made to the following detailed description of the test device in terms of various embodiments. Wherein the camera 10 is mounted on the mounting part 7 of the testing device.
The camera 10 is an imaging assembly including a lens 19 and an imaging section 20. The imaging section 20 includes an image sensor, a processing module, a circuit section, and the like. The light enters the imaging component 20 through the lens 19 and falls on the image sensor to obtain an original image, and then the processing module processes the original image to obtain a processed image. The processed image is transmitted from the circuit part to the outside.
The image sensor is used for converting optical signals into electrical signals, and can be a charge coupled device (Charge Couple Device, CCD), a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS); the circuit component may be, for example, a circuit or a wireless communication interface. The processing module is used for processing the image, for example, a digital signal processor (Digital Signal Processing, DSP) can be used for processing the image, for example, the processing of the image can be: black level correction, lens 19 shading correction, green balance, white balance, color correction, and the like.
Because errors occur in the processing of the lens 19 of the camera 10, manufacturing errors may occur in the processing module, assembly errors may occur in the manufacturing process of the camera 10, and the imaging quality of the produced camera 10 is not in accordance with the requirements, therefore, the camera 10 needs to be tested to determine whether the camera 10 meets the use requirements of users.
The test case 15 includes a case opening 16, and the case opening 16 is used for allowing the camera 10 to enter the test case 15, and the test case 15 is used for providing a test environment for the camera 10. The camera 10 can be driven by the testing device to enter the testing box 15.
In the embodiment of the present invention, the test box 15 has a cavity structure inside, and the test box 15 can be accessed through the box opening 16. The inside of the test case 15 is provided with a light source for providing light for test. When testing the camera 10, the light source is turned on, so that the inside of the test case 15 provides a test environment for testing the camera 10.
The cavity structure inside the test box 15 may be a cube, a hemisphere, or the like. In order to provide a test environment, the surface of the cavity structure may be subjected to a predetermined treatment. For example, the surface of the cavity structure is painted white or green, etc.
The specific test process is as follows: the user installs the camera 10 to be tested on the testing device, then the user adjusts the testing device, and under the drive of the testing device, the camera 10 enters the inside of the testing box 15. The light source of the test case 15 is turned on to provide light for testing, thereby creating an environment for testing inside the test case 15. Then, the camera 10 shoots to obtain an image, after the testing device obtains the image shot by the camera 10, the image can be analyzed, or the image is sent to a background server for analysis, and whether the imaging effect of the camera 10 meets the use requirement can be judged according to the analysis result of the image.
For example, the test case 15 of the embodiment of the present invention may be used to test the white balance effect of the camera 10, where the inside of the test case 15 provides an environment for performing the white balance test of the camera. The internal cavity of the test case 15 has a hemispherical structure, and the surface of the cavity is white. The light source inside the test case 15 is a test lamp, and the number of the test lamps is plural and is disposed around the cavity. The test lamp emits white light to establish a test environment for performing a white balance test in the cavity of the test case 15. The housing opening 16 of the test housing 15 is located at the center of the sphere of the cavity of the test housing 15. When performing a specific test, the user mounts the camera 10 to be tested on the mounting portion 7 of the camera mount 3 of the test device, and then moves the test device so that the test stand 2 on the test device enters the cavity of the test box 15. Since the camera head holder 3 is provided on the test stand 2, both the camera head 10 mounted on the camera head holder 3 and the camera head holder 3 enter the test box 15 along with the test stand 2. Then, the test lamp of the test case 15 is turned on, and the cavity in the test case 15 establishes a test environment. In this test environment, the user controls the camera 10 to capture an image by the test device. The testing device transmits the image to a background server, and the background server performs white balance verification on the image to obtain a testing result.

The following describes a test device according to an embodiment of the present invention, which may be used in the usage scenario shown in fig. 1.
Fig. 2 is a schematic structural diagram of a testing device with a camera according to an embodiment of the present invention, where the testing device may be used in the usage scenario shown in fig. 1. Fig. 3 is a top view of the test device shown in fig. 2.
Referring to fig. 2 and 3, an embodiment of the present invention provides a testing apparatus, including: the device comprises a device main body 1, a light barrier 4 arranged on the device main body 1, a test support 2 arranged on the light barrier 4 and an image pickup head seat 3.
The apparatus main body 1 is a main body of a test apparatus, and can support a light blocking plate 4, a test stand 2, and a camera mount 3. The device body 1 may also provide more functions. For example, in some specific examples, a circuit board is provided on the apparatus main body 1, and the circuit board may be electrically connected to the camera 10, and the circuit board may send the image to other devices for analysis processing after acquiring the image captured by the camera 10, or a processor and a memory are provided on the circuit board, so that analysis processing of the image may be performed on the circuit board. In other embodiments, a display screen or the like is further provided on the apparatus main body 1.

The light barrier 4 serves to block light for testing that leaks out of the box opening 16 of the test box 15. Wherein the light barrier 4 is provided between the test stand 2 and the apparatus main body 1, in other words, one side of the light barrier 4 is connected to the apparatus main body 1 and the other side of the light barrier 4 is connected to the test stand 2. Like this, when testing camera 10, test stand 2 stretches into the inside of test box 15, and the inside light source of test box 15 opens, and the light barrier 4 blocks the light that is used for the test that leaks from the box trompil 16 of test box 15, has maintained the stability of the inside test environment of test box 15, has improved the test accuracy to camera 10.
Regarding the specific implementation of the light barrier 4 to block the light leaking from the case opening 16 of the test case 15, for example, the light barrier 4 may have an area larger than that of the case opening 16, so that the light barrier 4 may cover the case opening 16.
In the test device according to the embodiment of the present invention, the camera mount 3 is slidably connected to the test stand 2, and the camera mount 3 includes a mounting portion 7, and the mounting portion 7 is used for mounting the camera 10. And the test stand 2 is used for entering the test box 15 from the box opening 16 when the camera 10 is tested, so that the camera 10 enters the test box 15. In other words, after the camera 10 is mounted on the mounting portion 7, the camera 10 is also mounted on the camera mount 3, so that the camera 10 and the test stand 2 are connected. When the user extends the test stand 2 into the test box 15, the camera 10 is brought into the test box 15.
There are various slide connection implementations of the camera mount 3 and the test stand 2, and two examples thereof are described below.
Example one: the test support 2 is provided with a first slide rail 11, the camera head seat 3 is provided with a first slide block, and the first slide block is in sliding connection with the first slide rail 11. For example, the first slider is disposed at the bottom of the camera mount 3, and a slot is opened on the test stand 2 as the first slide rail 11. After the first sliding block is clamped into the first sliding rail 11, the first sliding block can slide on the first sliding rail 11, so that the camera head seat 3 and the test support 2 are in sliding connection. The first sliding block and the first sliding rail 11 are matched for use, and one or more groups of the first sliding block and the first sliding rail 11 can be arranged on the testing device, and the embodiment of the invention is not limited in particular.
Example two: one end of the test support 2 far away from the device main body 1 is provided with a cavity, and one end of the camera head seat 3 stretches into the cavity of the test support 2, so that the camera head seat 3 can slide in a telescopic manner relative to the test support 2, and the camera head 10 is arranged at one end of the camera head seat 3 far away from the test support 2.
In the test apparatus according to the embodiment of the invention, a specific implementation manner of example one is described.
There are various specific implementations of the mounting portion 7. As shown in fig. 4, in a specific implementation, the camera mount 3 is disposed above the test stand 2 in a vertical direction, so that the camera mount 3 slides above the test stand 2, which facilitates control of the camera mount 3 by a user. The mounting part 7 on the camera head seat 3 is of a cavity structure, the camera head seat 3 is provided with a first slot 8 communicated with the mounting part 7 at one side far away from the light barrier 4, and the camera head seat 3 is provided with a second slot 9 communicated with the mounting part 7 at one side far away from the test support 2. Thus, the opening of the first slot 8 is located away from the light barrier 4 and faces the test box 15 when the camera 10 is tested. The opening position of the second slot 9 is far away from the test stand 2 and upwards in the vertical direction. The second slot 9 is used for embedding the camera 10 into the mounting part 7, and the first slot 8 is used for enabling the lens 19 of the camera 10 to extend out of the mounting part 7. So that the user can insert the imaging member 20 of the camera head 10 into the cavity of the mounting portion 7 through the second slot 9 and the lens 19 of the camera head 10 can protrude from the first slot 8 out of the cavity of the mounting portion 7. In this way, even if the camera 10 is firmly installed on the camera head seat 3, the user can conveniently disassemble and assemble the camera 10 on the camera head seat 3.
It will be appreciated that in some implementations, the sides of the camera head mount 3 may be slidably coupled to the test rack 2, with the sides of the camera head mount 3 being in a side-to-side position relative to the upper and lower ends. For example, a slider is provided on the left side of the camera mount 3, and the slider is slidably connected to a slide rail of the test stand 2.

In other words, the second light barrier 6 is provided between the apparatus main body 1 and the test stand 2. While the first light barrier 5 is mountable and dismountable on the second light barrier 6.
The camera 10 requires the use of electrical energy for taking images, for which purpose the device body 1 comprises a power supply interface for supplying the camera 10 with electrical power. A circuit is arranged on the camera 10, and the circuit of the camera 10 passes through the space between the first light barrier 5 and the second light barrier 6 and is detachably connected with a power supply interface. That is, the circuit of the camera 10 passes between the joint surface of the first light barrier 5 and the joint surface of the second light barrier 6, so that the circuit of the camera 10 is connected to the power supply interface, and the interface of the circuit of the camera 10 is connected to the power supply interface in a detachable connection manner. Thereby, the power supply to the camera head 10 is realized through the power supply interface. For example, referring to fig. 6, a circuit slot 21 is provided in the middle of one end of the second light barrier 6 near the first light barrier 5, and the circuit of the camera 10 is connected to the power supply interface of the apparatus body 1 through the circuit slot 21, or the circuit of the camera 10 and the power supply interface are connected at the junction of the first light barrier 5 and the second light barrier 6.

The light blocking plate 4 is used to block light for testing leaked from the case opening 16 of the test case 15, and when the light blocking plate 4 is provided in two, the test light of the test case 15 is liable to leak out from the gap between the first light blocking plate 5 and the second light blocking plate 6. In order to solve this problem, optionally, as shown in fig. 5, in the test device of the embodiment of the present invention, the joint surface of the first light barrier 5 and the joint surface of the second light barrier 6 are respectively provided with a stepped bump 17 that is lifted and lowered in a first direction, which is the same direction as the sliding direction of the camera mount 3 on the test stand 2. The joint surface of the first light barrier 5 is the surface of the first light barrier 5 which is jointed with the second light barrier 6, and the joint surface of the second light barrier 6 is the surface of the second light barrier 6 which is jointed with the first light barrier 5. When the first light barrier 5 is mounted on the second light barrier 6, the stepped projections 17 of the first light barrier 5 and the stepped projections 17 of the second light barrier 6 are engaged with each other. Thus, the joint surface of the first light barrier 5 and the second light barrier 6 forms a fold line along the sliding direction of the camera head base 3 on the test support 2, and when the camera head 10 is tested, light rays are emitted from the test box 15 along the sliding direction of the camera head base 3 on the test support 2, i.e. the light rays of the test box 15 are emitted from the box opening 16 of the test box 15 along the first direction. Since the light does not bend, the light is prevented from leaking from the positions of the first light barrier 5 and the second light barrier 6 by the engagement of the stepped projections 17. Thus, these light rays are blocked inside the test case 15 by the light blocking plate 4, and the stability of the test environment inside the test case 15 is further maintained.
It will be appreciated that the stepped bump 17 may have one or more bumps, and embodiments of the present invention are not limited in this respect. When the number of the stepped projections 17 is plural, the projections may be continuously raised or lowered, or may be zigzag.

The second direction is a direction perpendicular to the horizontal plane, and the third direction is perpendicular to the second direction, so that the third direction is parallel to the horizontal plane.
In a specific example, the sliding direction of the camera mount 3 on the test stand 2 is a direction parallel to the horizontal plane. Thus, by adjusting the adjusting member 18, the device body 1 can be moved in the second direction and the third direction, so that the camera 10 mounted on the test device can be moved in the second direction and the third direction along with the device body 1, and the adjustment of the position of the camera 10 in space can be realized. The spatial positions of the components of the test box 15 are generally relatively fixed, after the camera 10 extends into the test box 15, different spatial positions of the camera 10 relative to the test box 15 may be different, so that different images may be taken, and the analysis result of the images may be changed. By adjusting the adjusting member 18, the camera 10 can be located at a preset spatial position relative to the test box 15.
For example, in a specific example, the contour of the light barrier 4 is the same as the contour of the accommodating portion 12 of the test case 15, the case opening 16 of the test case 15 is located in the accommodating portion 12, and the contour of the light barrier 4 is smaller than the contour of the accommodating portion 12 of the test case 15. Therefore, when testing the camera 10, the light barrier 4 covers the box opening 16 of the test box 15, the light barrier 4 is also accommodated in the accommodating portion 12 of the test box 15, and a user can determine the relative position of the camera 10 relative to the test box 15 by comparing the outline shape of the light barrier 4 and the outline shape of the accommodating portion 12 of the test box 15. When the relative position is not satisfactory, the user can adjust the adjusting member 18 to adjust the position of the apparatus main body 1, thereby changing the relative position of the camera 10 with respect to the test case 15. For example, the outline shape of the light barrier 4 is circular, the outline shape of the accommodating portion 12 of the test box 15 is also circular, when the camera 10 is tested, the light barrier 4 blocks the box opening 16 of the test box 15, when the outline shape of the light barrier 4 and the outline shape of the accommodating portion 12 of the test box 15 are concentric circles, it can be determined that the camera 10 is located at a preset spatial position relative to the test box 15, photographing can be performed, and otherwise, the adjusting member 18 is adjusted, so that the outline shape of the light barrier 4 and the outline shape of the accommodating portion 12 of the test box 15 are concentric circles.

Alternatively, when the contour of the light barrier 4 is the same as the contour shape of the receiving portion 12 of the test case 15, the lens optical axis of the camera 10 passes through the geometric center of the contour of the light barrier 4 after the camera 10 is mounted on the mounting portion 7. In this way, the manufacturing of the test device and the test box 15 is facilitated, and the outline of the light barrier 4 and the circular outline shape of the accommodating portion 12 of the test box 15 are used as standard points for manufacturing and assembling other components.
For example, the outline of the light barrier 4 is circular, the inside of the test case 15 is a hemispherical cavity, and after the camera 10 is mounted on the mounting portion 7, the lens optical axis of the camera 10 passes through the center of the light barrier 4 and the center of the hemispherical cavity inside the test case 15. Therefore, when the equipment is manufactured, more manufacturing position references can be provided, and the equipment is convenient to manufacture; and facilitates the user to judge the position of the camera 10.
In order for the camera 10 to be mounted on the mounting portion 7, the lens optical axis of the camera 10 passes through the geometric center of the outline of the light barrier 4, which can be achieved by adjusting the dimensions of the test stand 2, the camera mount 3, and the light barrier 4.
It will be appreciated that in other specific examples, the surface of the test tank 15 is provided with a plurality of patterns or lines surrounding the tank opening 16, the shape of these patterns or lines being the same as the contour shape of the light barrier 4, but the shape of these images or lines being different. The user can estimate the position of the camera 10 by comparing the shape of the light barrier 4 with those of the patterns or lines, thereby confirming the degree of adjustment of the adjustment member 18. For example, the outline of the light barrier 4 is circular, and the patterns or lines are a plurality of concentric circles of different sizes.
In summary, the test apparatus includes the apparatus main body 1, the light barrier 4, the test stand 2, and the camera mount 3, where the light barrier 4 is disposed on the apparatus main body 1, and the light barrier 4 is used to block the light for testing leaking from the case opening 16 of the test case 15.
