[0047] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0048] Monitoring devices are applied in different fields, such as: transmission line monitoring, security monitoring, etc. The imaging quality of monitoring devices is crucial. Especially when monitoring devices are applied outdoors, facing different meteorological environments, the imaging quality of monitoring devices also varies. Therefore, it is necessary to conduct factory inspections on the imaging quality of monitoring devices when the monitoring environment is relatively blurred.

[0049] In the related art, a fog-making machine is used to simulate a fog environment, and a monitoring device is placed in the simulated environment for imaging quality detection of the monitoring device.

[0050] However, due to different models of monitoring devices, the corresponding detection conditions also vary. The monitoring device needs to be adjusted multiple times in the simulated environment, making it difficult to improve the detection efficiency. Therefore, there is an urgent need for a detection device that can meet different detection requirements to improve the detection efficiency.

[0051] To overcome the defects in the prior art, the present application provides a detection device. The test bench moves relative to the pattern card to meet the detection requirements of imaging components of different specifications. At the same time, the imaging component and the pattern card can be made opposite to each other, and the detection pattern of the corresponding pattern card can be obtained. Among them, the environment simulator of the detection device can generate an occluder and block it between the imaging component and the pattern card, so as to realize the imaging detection of the imaging component in different environments. The controller can obtain the detection pattern and analyze the detection pattern to determine the imaging detection result of the imaging component. In this way, the detection efficiency is improved through the detection device provided by the present application.

[0052] The following will describe the content of the present application in detail with reference to the accompanying drawings, so that those skilled in the art can understand the content of the present application more clearly and in detail.

[0053] See Figures 1 - 6 , define the first direction as X, the second direction as Y, and the third direction as Z.

[0054] An embodiment of the present application provides a detection device 100 for performing imaging detection on an imaging component 200, etc. in the presence of an occluder to detect the imaging quality of the imaging component 200 in the presence of an occluder. The imaging component 200 in the embodiment of the present application can be a camera, a monitoring device, etc.

[0055] The detection device 100 in the embodiment of the present application includes: a test component 110, a test bench 120, and a controller. Among them, the test component 110 includes a pattern card 111 and an environment simulator 112; the environment simulator 112 is used to generate an occluder. A pattern is set on the card surface of the pattern card 111, and the pattern can be a grayscale pattern, a dot pattern, or a physical pattern, etc., and can also be a combination of these different patterns. The embodiment of the present application does not make specific requirements for this.

[0056] The environment simulator 112 can be a smoke generator, a sprayer, a dust simulation device, etc. It can be understood that the smoke generator generates flowing smoke, the sprayer can generate water mist, and the dust simulation device can generate wind to blow dust. Therefore, the occluder in the embodiment of the present application can be smoke, water mist, dust, etc.

[0057] The imaging component 200 to be detected is installed on the test bench 120, and the test bench 120 is movable relative to the pattern card 111. In this way, by adjusting the relative position between the test bench 120 and the pattern card 111, the imaging focal length requirements of different imaging components 200 can be met, the applicable range of the detection device 100 can be improved, and the detection efficiency can be further enhanced.

[0058] The imaging end of the imaging component 200 faces the pattern card 111, and obtains the detection pattern of the pattern card 111 through the shielding object; the controller is electrically connected to the imaging component 200, and the controller analyzes the detection pattern obtained by the imaging component 200. By processing and analyzing the detection pattern through the controller, the imaging result of the imaging component 200 through the shielding object can be quickly obtained, the detection time of a single imaging component 200 is reduced, and the detection efficiency is improved.

[0059] In some alternative embodiments, the detection device 100 further includes a driving component 130. The driving component 130 is connected to the test bench 120, and the driving component 130 drives the test bench 120 to move so that the imaging end of the imaging component 200 and the pattern card 111 are opposite. In this way, through the setting of the driving component 130, the distance between the test bench 120 and the pattern card 111 can be accurately and quickly controlled, the installation and debugging time of the imaging component 200 can be reduced, and thus the detection efficiency can be improved.

[0060] It should be noted that the driving component 130 in the embodiments of the present application can output circular motion, and then convert the circular motion into linear motion through a transmission mechanism, and generate a driving force to move the test bench 120 relative to the pattern card 111, and adjust the relative position between the test bench 120 and the pattern card 111 to further meet the test requirements of the imaging focal length of the imaging component 200 installed on the test bench 120.

[0061] In a specific embodiment, the driving component 130 includes a slide rail 131. The slide rail 131 extends along the first direction (X), and the pattern card 111 is located at one end of the slide rail 131; the test bench 120 is slidably connected to the slide rail 131.

[0062] In the embodiments of the present application, the test bench 120 moves relative to the pattern card 111 along the first direction (X) on the slide rail 131. The slide rail 131 provides a fixed moving track, enabling the test bench 120 to move precisely along the first direction (X), which helps to keep the relative position between the test bench 120 and the pattern card 111 consistent, reduces the adjustment steps after the imaging component 200 is installed on the test bench 120, and further improves the detection efficiency of the detection device 100.

[0063] See Figure 2, in the embodiments of the present application, there are two slide rails 131. The two slide rails 131 are arranged at intervals and in parallel along the second direction (Y). The test bench 120 is slidably connected to the two slide rails 131. In this way, the shaking during the movement of the test bench 120 relative to the slide rails 131 can be reduced, the connection stability between the test bench 120 and the slide rails 131 can be improved, and further the movement stability of the test bench 120 relative to the slide rails 131 can be improved.

[0064] Optionally, the driving assembly 130 further includes a first driving member 132. The first driving member 132 is connected to the test bench 120 and is configured to drive the test bench 120 to move.

[0065] Exemplarily, the first driving member 132 can be a handle. The staff operates the handle to rotate, and transmits the driving force to the test bench 120 through a transmission mechanism, so that the test bench 120 can move along the slide rail 131. It is not difficult to understand that the transmission mechanism can be a gear-rack mechanism or a lead screw-nut mechanism, etc.

[0066] In this way, through the mutual cooperation of the first driving member 132 and the transmission mechanism, the circular motion of the first driving member 132 can be converted into a linear motion to drive the test bench 120 to move along the first direction (X), and further adjust the distance between the test bench 120 and the pattern card 111 to meet the test requirements of the imaging member 200.

[0067] Of course, the first driving member 132 can also be a motor. The motor can also output circular motion and transmit the driving force to the test bench 120 through a transmission mechanism, so that the test bench 120 can move along the slide rail 131.

[0068] In an alternative embodiment, the driving assembly 130 further includes a transmission belt 133 and a pulley 134. The transmission belt 133 is respectively connected to the pulley 134 and the test bench 120. The first driving member 132 drives the test bench 120 to move through the transmission belt 133.

[0069] Combined Figure 2 and Figure 3 , the pulley 134 and the test bench 120 are arranged at intervals along the first direction (X). The pulley 134 is located between the test bench 120 and the pattern card 111. The first end of the transmission belt 133 is fixedly connected to the test bench 120. The transmission belt 133 bypasses the pulley 134 and is connected to the first driving member 132 on the test bench 120. When the first driving member 132 rotates, the transmission belt 133 winds around or unfolds from the first driving member 132, realizing the movement of the test bench 120 along the first direction (X).

[0070] In this way, through the arrangement of the first driving member 132, the transmission belt 133, and the pulley 134, the adjustment efficiency and accuracy of the movement of the test bench 120 in the first direction (X) are improved. In addition, the transmission structure of the transmission belt 133 and the pulley 134 is simple, the overall installation difficulty of the detection device 100 is reduced, the production efficiency of the detection device 100 is improved, and it also helps to reduce the cost of the detection device 100.

[0071] Optionally, the test bench 120 includes a support portion 121 and a movable portion 122. The movable portion 122 is used to mount the imaging member 200, and the movable portion 122 is connected to one end of the support portion 121 along the second direction (Y); the movable portion 122 moves relative to the support portion 121 along at least one of the second direction (Y) and the third direction (Z); the first direction (X), the second direction (Y), and the third direction (Z) are perpendicular to each other.

[0072] In this way, the position of the movable portion 122 relative to the support portion 121 along the second direction (Y) and / or the third direction (Z) can be adjusted, and then the imaging member 200 mounted on the movable portion 122 can be driven to move along the second direction (Y) and / or the third direction (Z), so as to adjust the imaging end of the imaging member 200 to face the pattern card 111, which helps the imaging member 200 to obtain the detection pattern of the pattern card 111 and improves the accuracy of the detection result of the imaging member 200 by the detection device 100.

[0073] It should be noted that the movable portion 122 may move relative to the support portion 121 only along the second direction (Y) or only along the third direction (Z). The movable portion 122 may also move relative to the support portion 121 along the second direction (Y) and the third direction (Z). In this way, the relative position of the test bench 120 and the pattern card 111 can be adjusted from multiple directions, thereby improving the accuracy of the detection result.

[0074] As a possible implementation manner, the driving assembly 130 includes a second driving member 135. The second driving member 135 is disposed on the movable portion 122, and the second driving member 135 drives the movable portion 122 to move relative to the support portion 121 along the second direction (Y).

[0075] In the embodiment of the present application, the second driving member 135 may be a handle. The staff rotates the handle to output a circular motion, and then converts the circular motion into a linear motion through a transmission mechanism, so that the movable portion 122 moves along the second direction (Y).

[0076] The second driving member 135 may also be a motor. The motor outputs a circular motion, and then converts the circular motion into a linear motion through a transmission mechanism, so that the movable portion 122 moves along the second direction (Y).

[0077] Among them, the transmission mechanism in this part can be a gear-rack transmission mechanism, a belt and pulley transmission mechanism, a nut-screw transmission mechanism, etc. The embodiments of the present application do not make specific requirements for this.

[0078] Optionally, the driving assembly 130 further includes a third driving member 136. The third driving member 136 is disposed on the movable portion 122, and the third driving member 136 drives the movable portion 122 to move relative to the supporting portion 121 along the third direction (Z).

[0079] In the embodiment of the present application, the third driving member 136 can be a handle. The staff rotates the handle to output circular motion, and then converts the circular motion into linear motion through the transmission mechanism, so that the movable portion 122 moves along the third direction (Z).

[0080] The third driving member 136 can also be a motor. The motor outputs circular motion, and then converts the circular motion into linear motion through the transmission mechanism, so that the movable portion 122 moves along the third direction (Z).

[0081] Among them, the transmission mechanism in this part can be a gear-rack transmission mechanism, a belt and pulley transmission mechanism, a nut-screw transmission mechanism, etc. The embodiments of the present application do not make specific requirements for this.

[0082] In some alternative embodiments, the testing assembly 110 further includes a light-emitting member 113. The light-emitting member 113 is located on the side of the pattern card 111 away from the test bench 120, and the light-emitting member 113 is configured to emit light to irradiate the pattern card 111.

[0083] In this way, the light emitted by the light-emitting member 113 illuminates the test card, forming a simulation of the imaging light requirement of the imaging member 200, further ensuring the imaging light-sensitive requirement of the imaging member 200 and improving the detection effect.

[0084] To implement the detection of the imaging member 200 under different lighting conditions, referring to Figure 7 , the testing assembly 110 in the embodiment of the present application includes a light regulator 140. The light regulator 140 is electrically connected to the light-emitting member 113 and the controller respectively.

[0085] In this way, the light regulator 140 adjusts the light intensity of the light-emitting member 113 according to the instruction of the controller to simulate different lighting test environments, thereby improving the reliability and accuracy of the detection of the imaging member 200.

[0086] Exemplarily, the light regulator 140 in the embodiment of the present application can be a knob-type resistance regulator, and the light intensity of the light-emitting member 113 is adjusted by stepless adjustment of the resistance.

[0087] It should be noted that, referring to Figure 8, in the embodiment of the present application, the light-emitting component 113 includes a diffusion plate 1131, a light guide plate 1132, a lamp board 1133, and a reflector 1134. The diffusion plate 1131, the light guide plate 1132, the lamp board 1133, and the reflector 1134 are arranged in sequence along the thickness direction of the light-emitting component 113. A sandwich layer is formed between the light guide plate 1132 and the reflector 1134 to accommodate the lamp board 1133. The lamp board 1133 emits light in the sandwich layer. The light of the lamp board 1133 irradiates on the light guide plate 1132 and the reflector 1134, and the reflector 1134 reflects the light to the light guide plate 1132, so as to lead the pipeline out to the diffusion plate 1131 through the light guide plate 1132, and the light uniformly irradiates on the pattern card 111 through the diffusion plate 1131.

[0088] As an optional implementation manner, the detection device 100 further includes a detection box 150. The detection box 150 has an accommodation space, and the test bench 120, the pattern card 111, and the driving assembly 130 are all located in the accommodation space; the environment simulator 112 is located outside the detection box 150 and communicates with the accommodation space to introduce an occluder into the accommodation space.

[0089] Exemplarily, see Figure 2 , the test bench 120, the pattern card 111, the driving assembly 130, and the light-emitting component 113 are all located in the accommodation space. Among them, the test bench 120, the pattern card 111, and the light-emitting component 113 are arranged in sequence along the first direction (X). The slide rail 131 is arranged on the inner bottom wall of the detection box 150, and the pulley 134 is located between the test bench 120 and the pattern card 111.

[0090] The environment simulator 112 is located outside the detection box 150, which can reduce the space occupation ratio of the detection box 150 and is beneficial to the miniaturization of the detection device 100. The environment simulator 112 communicates with the accommodation space of the detection box 150 to introduce an occluder into the accommodation space.

[0091] Specifically, a communication hole 151 is provided on the side wall of the detection box 150. The environment simulator 112 communicates with the accommodation space of the detection box 150 through the communication hole 151 to introduce generated smoke, water mist, or dust into the detection box 150 to form an occlusion of the imaging end of the imaging component 200.

[0092] In the embodiment of the present application, the accommodation space of the detection box 150 forms a closed environment for accommodating smoke, water mist, or dust, preventing the diffusion of smoke, water mist, dust, etc., so that the accuracy of the detection structure decreases. At the same time, it also prevents these occluders from affecting the safety of the staff. In addition, placing some components of the detection device 100 in the detection box 150 is convenient for the transportation of the detection device 100.

[0093] Optionally, the test component 110 further includes a concentration detector located in the accommodation space. The concentration detector and the environmental simulator 112 are respectively electrically connected to the controller. The concentration detector is configured to detect the concentration of the occluder in the accommodation space.

[0094] In this way, based on the measurement results of the concentration detector, the controller corrects the detection image analysis process of the imaging member 200, and accurate measurement results under a certain specific concentration condition can be obtained. In addition, there is a feedback relationship between the concentration detector and the controller. For example, when the detected value of the concentration detector is greater than or equal to the preset concentration value of the controller, the environmental simulator 112 stops generating the occluder.

[0095] In an optional implementation manner of the present application, the detection device 100 further includes a signal lamp 160, and the signal lamp 160 is electrically connected to the controller.

[0096] The signal lamp 160 is electrically connected to the controller. The working state and detection results of the detection device 100 are obtained through the controller and displayed through the signal lamp 160, so that the detection staff can understand the working state and detection results of the detection device 100. In this way, the stable operation of the detection device 100 is ensured, and the detection efficiency is improved.

[0097] Exemplarily, the signal lamp 160 emits yellow light to indicate that the detection device 100 is in the detection work; the signal lamp 160 can emit green light to indicate that the detection quality of the imaging member 200 meets the standard; the signal lamp 160 emits red light to indicate that the detection quality of the imaging member 200 does not meet the standard.

[0098] See Figure 9 , an embodiment of the present application can also provide a control method for the detection device 100, including:

[0099] S201. Adjust the relative positions of the test bench 120 and the pattern card 111 so that the imaging member 200 to be detected is opposite to the pattern card 111.

[0100] S202. Turn on the environmental simulator 112 and the concentration detector.

[0101] When the environmental simulator 112 is turned on, the environmental simulator 112 generates an occluder, and the concentration detector detects the concentration of the occluder. When the concentration of the occluder is equal to or greater than the preset concentration value of the controller, the environmental simulator 112 stops working.

[0102] S203. The imaging member 200 obtains the detection pattern of the pattern card 111, and the controller analyzes the detection, forms a detection result, and displays the test result through the indicator light.

[0103] It should be noted that phrases such as "an embodiment", "embodiments", "exemplary embodiments", "some embodiments", etc. mentioned in the specification indicate that the described embodiments may include specific features, structures or characteristics, but not necessarily every embodiment includes such specific features, structures or characteristics. In addition, such phrases do not necessarily refer to the same embodiment. Moreover, when combining specific features, structures or characteristics with an embodiment, it is within the knowledge scope of those skilled in the art to implement such features, structures or characteristics in combination with other embodiments, whether explicitly or implicitly described.

[0104] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part according to the context, the term "one or more" used in the text can be used to describe any feature, structure or characteristic in a singular sense, or can be used to describe a combination of features, structures or characteristics in a plural sense. Similarly, at least in part according to the context, terms such as "a" or "the" can also be understood to convey a singular usage or a plural usage.

[0105] It should be easily understood that the terms "on", "above" and "over" in this application should be interpreted in the broadest manner, so that "on" not only means "directly on something", but also includes the meaning of "on something" with intermediate features or layers therebetween, and "above" or "over" not only includes the meaning of "above" or "over something", but may also include the meaning of "above" or "over something" without intermediate features or layers therebetween (i.e., directly on something).

[0106] In addition, for the convenience of description, spatial relative terms such as "below", "beneath", "under", "above", "over" etc. may be used in the text to describe the relationship of one element or feature relative to other elements or features as shown in the figure.
