[0033] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0034] The first embodiment of the present disclosure provides a detection system for a camera device, such as Figure 1 and Figure 2 As shown, the detection system includes a shell 1, which can be, for example, a fully enclosed shell or a semi-enclosed shell so as to form a predetermined optical fiber environment; a carrying platform 2 is provided at the bottom of the shell 1, and a movable camera device 3 is provided on the carrying platform 2. The camera device here can be, for example, a camera, a camera, or the like that is used solely for filming, or it can be other devices with a camera function to realize image capture, which is not limited here.

[0035] The camera device 3 can move along a predetermined direction on the carrying platform 2, and the predetermined direction here can be, for example, the length direction of the carrying platform 2. Here, the carrying platform 2 is provided with, for example, a guide rail 21, and the guide rail 21 is provided on the carrying platform 2 along a predetermined direction, and a slider is provided at the bottom of the camera device 3 so that it can slide on the guide rail 21.

[0036] Furthermore, an array light source 4 is disposed above the mounting platform 2. The array light source 4 can be disposed, for example, on the top plate of the housing 1, which is disposed directly opposite the mounting platform 2. The array light source 4 is used to simulate different variable light environments in the housing 1. Specifically, in this embodiment, the array light source 4 can realize automatic adjustment of light intensity and automatic adjustment of irradiation direction, so as to simulate different variable light environments. In particular, different variable light environments can be simulated according to different positions of the camera device 3.

[0037] The array light source 4 here includes a plurality of light source units 41 arranged in an array, and different variable light environments are formed by turning on and off each of the light source units 41 or adjusting the light intensity and the irradiation direction of each of the light source units 41. The light source units 41 here are arranged in N rows along a predetermined direction, for example, wherein the n1 row of light source units 41 farthest from the camera device 3 are long-distance light source units, the n2 row of light source units 41 closest to the camera device 3 are long-distance light source units, and the other rows of light source units 41 are middle light source units.

[0038] Further, a collection object 5 is arranged in the predetermined direction, and the collection object 5 may be, for example, a bar graph for detection or an object for imaging, and the collection object 5 is arranged relative to the camera device 3 so that the camera device 3 can shoot the collection object 5 to obtain an image. The collection object 5 here is arranged, for example, close to the side plate of the housing 1, and the distance between the camera device 3 and the collection object 5 can be adjusted by moving the camera device 3 on the mounting platform 2.

[0039] In addition, the detection system further includes a control device 6, which can be, for example, disposed outside the housing 1, and connected to the camera device 3 and the array light source 4 in the housing 1 to control the camera device 3 and the array light source 4. The control device 6 in this embodiment, for example, needs to be installed with camera device test software and light source control software, the light source control software is used to control the light emission of the array light source 4 to simulate different variable light environments, and the camera device test software can control the camera device 3 to shoot, obtain the image captured by the camera device 3, and analyze the image quality of the image.

[0040] The embodiments of the present disclosure can better detect the imaging performance of the camera device by simulating a variable light environment, thereby providing a basis for detecting and verifying the performance indicators of the camera device.

[0041] The second embodiment of the present disclosure provides a detection method for a camera device, which adopts the detection system of the first embodiment, such as Figure 3 As shown, the detection method comprises:

[0042] S101, controlling the array light source to emit light based on the position of the light source unit and the predetermined light intensity to simulate a variable light environment.

[0043] In this step, the array light source is controlled to emit light based on the position of the light source unit and the predetermined light intensity to simulate a variable light environment. First, the camera device 3 is set on the carrying platform 2, for example, the camera device 3 is installed on the carrying platform 2 and connected to a power supply, and the camera device 3 is enabled to reciprocate along the guide rail 21 on the carrying platform 2 in a predetermined direction to adjust the distance between the camera device 3 and the collection object 5 (for example, a bar graph for detection or an object for imaging).

[0044] Furthermore, the camera detection software and the light source control software on the control device 6 are turned on, and the camera 3 and the array light source 4 are turned on, and then the array light source 4 is controlled by the light source control software to emit light based on the position of the light source unit 41 and the predetermined light emission mode. The predetermined light emission intensity here is, for example, dim light, strong light, or the light emission intensity can be divided into multiple levels to select different levels of light emission intensity, etc.

[0045] The light array light source 4 emits light to simulate a variable light environment, wherein the variable light environment is, for example, close-range strong light-middle dark light-long-range strong light, close-range dark light-middle dark light-long-range strong light, close-range strong light-middle dark light-long-range dark light, etc. The close-range, middle, and long-range here are specifically determined based on the positions of different light source units 41, and are particularly divided based on the number of light source units 41 in the light source array 4 and along the moving direction of the camera device 3. For example, the three rows of light source units 41 farthest from the camera device 3 are close-range light source units, the three rows of light source units 41 closest to the camera device are long-range light source units, and the other rows of light source units 41 are middle light source units. The specific positions of the close-range, middle, and long-range here can be adjusted according to the actual use environment.

[0046] In addition, when simulating a variable light environment by emitting light through the array light source 4, the irradiation direction of the light source unit 41 can also be controlled to simulate the imaging effect of the camera device 3 when light with different irradiation directions or irradiation angles is irradiated onto the collection object 5.

[0047] S102, controlling the camera device to shoot a collection object and obtain images of the collection object under different variable light environments.

[0048] After controlling the array light source to emit light based on the position of the light source unit and the predetermined light intensity to simulate the variable light environment in step S101, in this step, the camera device is controlled to shoot the acquisition object and obtain images of the acquisition object under different variable light environments. Specifically, in this step, by simulating different variable light environments, that is, detecting the imaging effect of the camera device 3 under different light source illumination conditions. Here, in particular, the image of the acquisition object 5 shot by the camera device 3 is obtained, and different images here reflect different variable light environments.

[0049] Because the use environment of the camera device sometimes has obvious light changes, such as in mines and tunnel pipelines, the light changes are diverse. When shooting under different light change conditions such as close-range strong light-middle dark light-long-range strong light, close-range dark light-middle dark light-distant strong light, close-range strong light-middle dark light-distant dark light, if the performance of the camera device is not high, although the image quality is good under uniform light conditions, when encountering a usage scenario with variable light, there will be large image chromatic aberration, image color distortion and other phenomena, affecting the normal acquisition and use of the image. For this reason, in this step, different images are acquired by simulating different variable light environments, so as to more accurately judge the performance of the camera device.

[0050] S103: Outputting a detection result of the camera device based on the quality of the image.

[0051] After the camera device is controlled to shoot the acquisition object and obtain the image of the acquisition object under different light-changing environments through the above step S102, in this step, the detection result of the camera device is output based on the quality of the image. Specifically, after the image of the acquisition object 5 shot by the camera device 3 is obtained, the image under different light-changing environments is transmitted to, for example, the camera device detection software, and the imaging parameters representing the image quality of the image are detected by the camera device detection software. The imaging quality here is reflected, for example, by color difference, saturation difference, etc.

[0052] In this step, for example, the imaging parameters (such as imaging saturation) of the imaging device 3 under variable light conditions can be compared with the actual parameters (such as actual color) of the acquisition object 5 to obtain, for example, color difference, thereby comparing the imaging quality; the imaging quality of the imaging device 3 under variable light conditions can also be compared with the imaging quality of the acquisition object 5 photographed under normal uniform light indoors, for example, by comparing parameters such as saturation and contrast, thereby outputting the test result of the camera device 3 as qualified or unqualified.

[0053] The embodiments of the present disclosure can better detect the imaging performance of the camera device by simulating a variable light environment, thereby providing a basis for detecting and verifying the performance indicators of the camera device.

[0054] Based on the same inventive concept as the second embodiment described above, a third embodiment of the present disclosure provides a detection device for a camera device, the detection device comprising:

[0056] The image acquisition module is used to control the camera device to shoot the acquisition object and acquire the image of the acquisition object under different variable light environments.

[0057] A result output module is used to output the detection result of the camera device based on the quality of the image.

[0058] Furthermore, the variable light environment includes at least close-range strong light-middle dark light-long-range strong light, close-range dark light-middle dark light-long-range strong light, and close-range strong light-middle dark light-long-range dark light.

[0059] Furthermore, the environment simulation module is also used to control the irradiation direction of the light source unit.

[0060] Furthermore, the result output module is at least used to compare the imaging parameters of the camera device under variable light conditions with the actual parameters of the acquisition object and / or to compare the imaging quality of the acquisition object photographed by the camera device under variable light conditions and under normal uniform light indoors.
