[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features can be combined with each other.

[0076] Imaging equipment is used in various fields, such as vehicle monitoring, electronic equipment monitoring, and power transmission line monitoring. The image quality of imaging equipment is crucial. Therefore, it is necessary to test the image quality of imaging equipment before it leaves the factory, especially the lenses within the equipment.

[0077] In related technologies, imaging equipment uses monocular or multi-lens cameras, especially multi-lens cameras, requiring imaging inspection of all lenses. Each lens is positioned opposite a test card at a different station on the inspection equipment, and the test card is photographed and then analyzed.

[0078] However, such inspection equipment is typically applicable to a single model of imaging equipment. Therefore, there is an urgent need for an inspection device that can meet the different inspection requirements of various imaging devices in order to improve inspection efficiency.

[0079] To overcome the shortcomings of existing technologies, this application provides a testing device, including a testing platform, a controller, and at least one testing component. The testing platform has a mounting section for mounting the imaging device to be tested. The testing component and the mounting section are correspondingly arranged. The imaging end of the imaging device faces the testing component and acquires the test image of the testing component. The controller is electrically connected to the imaging device to be tested and analyzes the test image acquired by the imaging device. Such a testing device can meet the testing needs of various imaging devices and improve testing efficiency.

[0080] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0081] like Figures 1 to 7 As shown, this application embodiment provides a testing device 100, including a testing stage 120, a controller, and at least one testing component 130.

[0082] The testing station 120 is provided with at least one mounting part 121, which is used to mount the imaging device 200 to be tested; at least one test component 130 and at least one mounting part 121 are arranged correspondingly to each other, the imaging end of the imaging device 200 faces the test component 130, and acquires the test image of the test component 130.

[0083] The controller is electrically connected to the imaging device 200 to be inspected, and the controller analyzes the inspection images acquired by the imaging device 200 to be inspected.

[0084] In the detection device 100 provided in this application embodiment, one or more mounting parts 121 can mount multiple identical imaging devices 200 or multiple different imaging devices 200, and simultaneously detect all imaging devices 200, thereby improving the detection efficiency of the detection device 100. The position of the test component 130 can be adjusted to improve the efficiency of the imaging end of the imaging device 200 in acquiring the detection image of the test component 130, further enhancing the detection efficiency of the detection device 100.

[0085] The testing station 120 is provided with at least one mounting part 121. It can be understood that the testing station 120 may be provided with one or more mounting parts 121. Regardless of the number of mounting parts 121, some of the multiple mounting parts 121 have corresponding test components 130.

[0086] When there is only one mounting part 121 on the testing table 120, the testing equipment 100 can test one imaging device 200, which may have one lens or multiple lenses. The testing table 120 has multiple mounting parts 121. Some of the mounting parts 121 can be used to mount the imaging device 200 to be tested, or each mounting part 121 can be used to mount the imaging device 200 to be tested. It should be noted that the number of mounting parts 121 can be selected according to actual needs, and this embodiment does not specifically limit this number.

[0087] In this embodiment, at least one test component 130 and at least one mounting part 121 correspond to each other. The test component 130 may include a test card 131 and / or a temperature radiation element 136. The imaging end of the imaging device 200 is opposite to the test component 130, and the detection image of the test component 130 is acquired through the imaging end. It should be noted that, in this embodiment, the imaging end of the imaging device 200 is the lens of the imaging device 200.

[0088] It is understood that when the imaging device 200 and the test component 130 are facing each other, the imaging device 200 can form a detection image on the pattern on the test card 131 of the test component 130. Of course, in some embodiments, the test card 131 can radiate temperature, and the imaging device 200 can also form a detection image based on the radiated temperature of the test card 131.

[0089] The following description uses test card 131 as an example to illustrate the various assembly structures of the testing equipment 100 provided in this application embodiment.

[0090] It is understood that different imaging devices 200 have different imaging focal lengths. By presetting the relative position between the test card 131 and the imaging device 200, the test card 131 can be placed within the imaging focal length range of the imaging device 200, thereby improving the accuracy of detection.

[0091] The controller and the imaging device 200 are electrically connected, so that the detection image acquired by the imaging device 200 can be transmitted to the controller, and the controller analyzes the detection image after receiving the corresponding signal.

[0092] It is understood that in some embodiments, there are multiple mounting parts 121, which are distributed sequentially and at intervals along the circumference of the testing table 120; there are multiple test components 130, and at least some of the multiple mounting parts 121 correspond one-to-one with multiple test cards 131. In this way, the testing equipment 100 can simultaneously test multiple imaging devices 200 of the same or different models.

[0093] like Figure 2As shown, in this embodiment, there are four mounting portions 121, which are distributed sequentially and at intervals along the circumference of the detection table 120. It should be noted that the detection table 120 can be square or circular; this embodiment does not impose a specific limitation on this. Furthermore, the four mounting portions 121 can be arranged at equal intervals or non-uniform intervals along the circumference of the detection table 120. This embodiment does not impose a specific limitation on this.

[0094] For example, there are three test components 130, and three of the three test components 130 and four mounting parts 121 are arranged correspondingly to each other. These three mounting parts 121 can simultaneously mount the imaging devices 200 to be tested. The imaging ends of the three imaging devices 200 to be tested are aligned with the test cards 131 in the corresponding test components 130, acquiring the detection images of the corresponding test cards 131 and transmitting them to the controller. The controller can simultaneously analyze the detection images acquired by these three imaging devices 200. The detection device 100 can simultaneously analyze the detection images of multiple imaging devices 200, improving detection efficiency.

[0095] It should be noted that the number of mounting parts 121 and test components 130 in the embodiments of this application is not limited to the number described above, and the specific number can be reasonably selected in actual use.

[0096] In some embodiments, the inspection stage 120 rotates about a rotation axis along the thickness direction of the inspection stage 120. Thus, the rotation of the inspection stage 120 can adjust the relative positional relationship between the imaging ends of the imaging device 200.

[0097] It is understood that the testing station 120 is provided with multiple mounting parts 121, and there are multiple corresponding test components 130. The test cards 131 in the test components are correspondingly set with some of the mounting parts 121. When the testing station 120 rotates around the rotation axis, the imaging device 200 mounted on the mounting part 121 can rotate around the rotation axis so that the imaging end of the imaging device 200 is opposite to the test card 131.

[0098] For example, an imaging device 200 to be tested is mounted on the mounting part 121a. The testing stage 120 rotates around the rotation axis, causing the mounting part 121a to rotate to the position of the mounting part 121b. At this position, the imaging device 200 acquires the test image of the test card 131. The imaging device 200 can be a monocular lens or a multi-lens lens. The lens is the imaging end of the imaging device 200.

[0099] When the monocular lens of the imaging device 200 is engaged, the testing stage 120 rotates around its rotation axis, causing the mounting section 121 to rotate. Mounting sections 121b, 121c, and 121d can all rotate to the position of mounting section 121a, allowing operators to install the corresponding imaging devices 200 on these four mounting sections 121. As the testing stage 120 continues to rotate, the mounting section 121 rotates to the position of the corresponding test card 131, and the imaging device 200 simultaneously acquires the test image from the test card 131. The testing device 100 can simultaneously test multiple imaging devices 200, improving testing efficiency.

[0100] Furthermore, when the imaging device 200 is a multi-lens system, for example, the imaging device 200 has three lenses, the imaging device 200 is mounted on the mounting part 121a. The inspection stage 120 rotates, and the mounting part 121a rotates to the position of the mounting part 121b, where one of the three lenses is inspected. Further, the inspection stage 120 continues to rotate, and the mounting part 121a rotates from the position of the mounting part 121b to the position of the mounting part 121c, where one of the two lenses that have not yet been inspected is inspected. The inspection stage 120 continues to rotate, and the mounting part 121a rotates from the position of the mounting part 121c to the position of the mounting part 121d, where the last lens that has not yet been inspected is inspected.

[0101] It is understood that mounting sections 121d, 121c, and 121b will sequentially rotate to mounting section 121a, where the imaging device 200 to be inspected will be mounted. As the inspection table 120 rotates, the device will sequentially pass through mounting sections 121b, 121c, and 121d. In this way, the inspection equipment 100 can perform continuous inspection of multiple imaging devices 200, improving inspection efficiency.

[0102] It should be noted that when the lens of a single imaging device 200 is monocular, multiple imaging devices 200 can be installed in the same mounting part 121 according to a certain pattern. For example, three imaging devices 200 can be installed sequentially in the same mounting part 121a along the thickness direction (Z direction) of the inspection stage 120. The inspection stage 120 rotates, causing the mounting part 121a to move sequentially to mounting parts 121b, 121c, and 121d, and the inspection of the imaging device 200 is completed at the corresponding positions. Alternatively, three imaging devices 200 can be installed sequentially in the same mounting part 121a along the horizontal direction. The inspection stage 120 rotates, causing the mounting part 121a to move sequentially to mounting parts 121b, 121c, and 121d, and the inspection of the imaging device 200 is completed at the corresponding positions.

[0103] At this time, mounting sections 121d, 121c, and 121b will rotate sequentially to mounting section 121a, where the imaging device 200 to be inspected will be mounted. As the inspection table 120 rotates, the device will pass through mounting sections 121b, 121c, and 121d in sequence. In this way, the inspection equipment 100 can perform continuous inspection of multiple imaging devices 200, improving inspection efficiency.

[0104] When multiple lenses of the imaging device 200 are installed in a mounting section 121, the relative positions of the mounting section 121 and the test card 131 need to be adjusted so that the lenses of the imaging device 200 and the test card 131 are aligned. In this embodiment, the mounting section 121 is movable relative to the testing stage 120 along a first direction (X direction); and / or, the mounting section 121 is movable relative to the testing stage 120 along a second direction (Y direction); the first and second directions intersect the thickness direction of the testing stage 120.

[0105] For example, the imaging device 200 is installed in the mounting part 121a. The detection stage 120 rotates, and the mounting part 121a rotates to the mounting part 121b. The mounting part 121a moves along a first direction (X direction) on the detection stage 120 to align a lens of the imaging device 200 with the corresponding test card 131, improving detection accuracy. The detection stage 120 continues to rotate, and the mounting part 121a rotates to the mounting part 121c. The mounting part 121a moves relative to the detection stage 120 along the first direction (X direction), changing the distance between the lens to be tested and the test card 131, facilitating the lens to acquire the detection image of the corresponding test card 131. It is understood that when the mounting part 121a rotates to the mounting part 121d, the mounting part 121a moves relative to the detection stage 120 along the first direction (X direction), which can change the relative position of the imaging device 200 and the test card 131, thereby aligning the lens of the imaging device 200 to be tested with the test card 131, so that the lens can acquire the detection image of the corresponding test card 131.

[0106] Of course, the mounting part 121a can also move relative to the detection stage 120 along the second direction (Y direction). It can be understood that moving the mounting parts 121a, 121b, and 121d along the second direction (Y direction) can increase the distance between the imaging device 200 and the test card 131, so that the test card 131 is within the imaging focal length range of the imaging device 200, and a clear detection image is obtained through the imaging device 200, thus improving the detection quality. Moving the mounting part 121a along the second direction (Y direction) at the mounting part 121c can change the relative position of the imaging device 200 and the test card 131, thereby aligning the lens of the imaging device 200 with the test card 131, facilitating the lens to acquire the corresponding detection image of the test card 131.

[0107] In some embodiments, the mounting part 121 can move relative to the detection stage 120, either along a first direction (X direction) or along a second direction (Y direction). Thus, by moving the mounting part 121 relative to the detection stage 120, the imaging end (lens) of the imaging device 200 is aligned with the corresponding test card 131 at various positions, which helps to acquire the detection image of the test card 131 and improves detection accuracy and efficiency.

[0108] It should be noted that the working principle of mounting parts 121b, 121c, and 121d is the same as that of mounting part 121a, and will not be described in detail here.

[0109] Furthermore, the first and second directions intersect the thickness direction of the testing stage 120. That is, the first and second directions and the thickness direction of the testing stage 120 can be perpendicular to each other. Of course, the first and second directions can be at an angle in the same plane and intersect the thickness direction of the testing stage 120. Regardless of the specific angle of intersection between the first and second directions and the thickness direction of the testing stage 120, the movement of the mounting part 121 relative to the testing stage 120 along the first and second directions can ensure that the imaging end of the imaging device 200 is aligned with the corresponding test card 131.

[0110] It is understood that the test card 131 in this embodiment is movable relative to the mounting part 121. In specific implementation, for a known model of imaging device 200, the focal length of each lens is fixed. During testing, the movable amount of the test card 131 relative to the mounting part 121 can be preset in advance, thereby improving the testing efficiency for the same model of imaging device 200. Alternatively, for testing a certain focal length range of the imaging device 200, the position between the test card 131 and the imaging end of the imaging device 200 can be adjusted by moving the test card 131 relative to the mounting part 121 to meet different testing requirements.

[0111] In some embodiments, the test assembly 130 further includes a light-emitting element 132. The side of the test card 131 facing away from the mounting portion 121 is connected to the light-emitting element 132. The light-emitting element 132 drives the test card 131 to move relative to the mounting portion 121. The light-emitting element 132 is electrically connected to a controller. And / or, the test assembly 130 further includes a teleconverter 133. The teleconverter 133 is located on the side of the test card 131 facing the mounting portion 121 and is movably positioned relative to the test card 131. The imaging end of the imaging device 200 acquires the detection image of the test card 131 through the teleconverter 133. Thus, the light-emitting element 132 can change the light intensity, and the teleconverter 133 adjusts the imaging position of the test card 131, facilitating the imaging device 200 to acquire the corresponding detection image of the test card 131 and improving detection efficiency.

[0112] The imaging device 200 operates both day and night. The lighting conditions are different during the day and night. The light-emitting element 132 is located in the accommodating cavity 111 and is located on the side of the test card 131 away from the mounting part 121. In this way, the light emitted by the light-emitting element 132 can illuminate both the accommodating cavity 111 and the test card 131, so as to acquire the detection image of the test card 131 under different lighting conditions.

[0113] It is understandable that when there are multiple test components 130, multiple light-emitting elements 132 may emit light simultaneously, and the required illumination intensity for the imaging devices 200 to be tested on adjacent mounting portions 121 may also differ. To prevent the light-emitting elements 132 from interfering with each other, this embodiment of the application attaches a test card 131 to the light-emitting element 132. This way, the light emitted by the light-emitting element 132 can only illuminate the test card 131. Furthermore, the light-emitting element 132 is electrically connected to a controller, which can control the luminous intensity of the light-emitting element 132 so that the detection device 100 can meet the detection requirements of different imaging devices 200. In addition, in this embodiment, the light-emitting element 132 can move the test card 131 relative to the mounting portion 121, adjusting the distance between the test card 131 and the corresponding imaging device 200, so that the imaging device 200 can efficiently acquire the detection image of the corresponding test card 131, improving detection efficiency.

[0114] Furthermore, the smaller the focal length of the imaging device 200, the larger the field of view. Conversely, the larger the focal length of the imaging device 200, the smaller the field of view. Simply put, in a limited space, to acquire the detection image of the test card 131, the distance between the imaging devices 200 and the test card 131 needs to be adjusted. For some imaging devices 200 with larger focal lengths, it is impossible to place the test card 131 very far from the mounting part 121. In this case, a teleconverter 133 can be placed between the test card 131 and the mounting part 121 to shorten the distance between them, allowing the imaging device 200 to acquire the detection image of the test card 131 through the teleconverter 133. Furthermore, for different imaging devices 200 with different focal lengths, the relative positions of the test card 131 and the teleconverter 133 can be adjusted so that the imaging device 200 can acquire the detection image through the teleconverter 133.

[0115] Specifically, the test assembly 130 also includes a slide rail 134 extending toward the mounting portion 121; a light-emitting element 132 is disposed on the slide rail 134, and the light-emitting element 132 drives the test card 131 to move relative to the mounting portion 121 via the slide rail 134; and / or, a teleconverter 133 is disposed on the slide rail 134, and the teleconverter 133 moves relative to the test card 131 via the slide rail 134. In this way, the light-emitting element 132 and the teleconverter 133 can move stably relative to the mounting portion 121 via the slide rail 134, facilitating the imaging device 200 to acquire the detection image of the test card 131 and improving detection efficiency.

[0116] For example, the light-emitting element 132 is disposed on the slide rail 134 along the Z direction, and the side of the light-emitting element 132 facing the slide rail 134 has a groove or hole. The light-emitting element 132 is connected to the slide rail 134 through the groove or hole. In this way, the light-emitting element 132 can drive the test card 131 to move relative to the mounting part 121 along the extension direction of the slide rail 134, so that the imaging device 200 to be tested on the mounting part 121 can acquire the test image of the test card 131. Similarly, the teleconverter 133 can also be disposed on the slide rail 134 in the same manner.

[0117] In some specific embodiments, the slide rail 134 can be a lead screw, and the groove or hole connecting the light-emitting element 132 and the teleconverter 133 to the slide rail 134 has threads, so that when the slide rail 134 rotates, the light-emitting element 132 and the teleconverter 133 move along the extension direction of the slide rail 134.

[0118] Furthermore, the test assembly 130 also includes a bracket 135, with one end of the bracket 135 connected to the slide rail 134 along the extension direction intersecting the slide rail 134. A teleconverter 133 is disposed at the end of the bracket 135 opposite to the slide rail 134. The bracket 135 drives the teleconverter 133 to move relative to the test card 131 via the slide rail 134. The teleconverter 133 is movable relative to the slide rail 134 along the extension direction intersecting the slide rail 134. This allows the imaging device 200 under test to effectively acquire the test image of the test card 131 through the teleconverter 133.

[0119] The bracket 135 in this embodiment includes a first bracket 1351 and a second bracket 1352. The first bracket 1351 is mounted on a slide rail 134 and has a hole or groove on the side facing the slide rail 134. The first bracket 1351 is connected to the slide rail 134 through the hole or groove and moves along the extending direction of the slide rail 134. The second bracket 1352 is mounted on the first bracket 1351, and the teleconverter 133 and the second bracket 1352 are fixedly connected. Thus, when the first bracket 1351 slides along the extending direction of the slide rail 134, it causes the teleconverter 133 to move relative to the mounting portion 121.

[0120] For example, the second bracket 1352 and the first bracket 1351 partially overlap and face each other along the extension direction of the slide rail 134. Both the first bracket 1351 and the second bracket 1352 are provided with connecting holes 1353, which are opposite to and communicate with each other along the extension direction of the slide rail 134. Threaded fasteners 1354 pass through the connecting holes 1353 of the first bracket 1351 and the second bracket 1352 to maintain a stable connection between the first bracket 1351 and the second bracket 1352. Of course, if the threaded fasteners 1354 loosen, the relative positions of the second bracket 1352 and the first bracket 1351 along the extension direction intersecting the slide rail 134 can be adjusted, thereby making the position of the teleconverter 133 connected to the second bracket 1352 relative to the slide rail 134 along the extension direction intersecting the slide rail 134 adjustable.

[0121] The testing equipment 100 also includes a drive assembly, which is electrically connected to the testing stage 120 and the testing component 130, and is also electrically connected to a controller. The controller instructs the drive assembly to drive the testing stage 120 to rotate and to move certain components in the testing component 130 relative to the mounting portion 121.

[0122] Furthermore, the driving component includes a first motor 140, which is disposed on the detection stage 120 and drives the detection stage 120 to rotate. The first motor 140 outputs a circular motion around the rotation axis to drive the detection stage 120 to rotate around the rotation axis. Thus, the rotation of the detection stage 120 causes a change in the position of the mounting part 121, and the mounting part 121 and the test component 130 are aligned. That is, the imaging end of the imaging device 200 to be tested on the mounting part 121 is aligned with the test card 131, and the corresponding detection image of the test card 131 is acquired.

[0123] The first motor 140 is electrically connected to the controller. When the controller issues a command, the first motor 140 starts and drives the testing platform 120 to rotate around its axis. When the mounting parts 121 are evenly arranged along the circumference of the testing platform 120, the rotation angle of the testing platform 120 is relatively uniform. The first motor 140 can be a stepper motor or a servo motor. The controller sends uniform pulse signals to the first motor 140 to precisely control the rotation of the testing platform 120, ensuring that the mounting parts 121 on the testing platform 120 are aligned with the test card 131. It can be understood that the arrangement of the first motor 140 facilitates the rotation control of the testing platform 120, reducing testing time and improving testing efficiency.

[0124] In some embodiments, the drive assembly further includes a reducer (not shown in the figure), the input end of which is connected to the drive end of the first motor 140, and the output end of which is connected to the detection platform 120. Thus, the gear ratio of the reducer in this embodiment converts the high speed of the first motor 140 to a low speed, while proportionally amplifying the output torque, thereby improving the response speed and control accuracy of the detection platform 120's rotation around its axis. When meeting the rotation requirements of the detection platform 120, by amplifying the torque of the first motor 140 through the reducer, a lower-power first motor 140 can be selected, thereby reducing the power consumption of the detection device 100.

[0125] In some embodiments, the driving assembly includes a second motor 141 disposed on the light-emitting element 132, the second motor 141 driving the light-emitting element 132 to move relative to the mounting portion 121; and / or, the driving assembly further includes a third motor 142 disposed on the teleconverter 133, the third motor 142 driving the teleconverter 133 to move relative to the test card 131.

[0126] Based on the aforementioned embodiment, the light-emitting element 132 is connected to the test card 131 on the side facing the mounting portion 121. The second motor 141 drives the light-emitting element 132 to move relative to the mounting portion 121, and the light-emitting element 132 drives the test card 131 to move relative to the mounting portion 121. In this way, the test card 131 can be moved quickly by driving the second motor 141. In actual use, the operator knows the focal length of the imaging device 200 to be tested and the imaging distance between the corresponding test card 131 and the imaging device 200. The controller outputs instructions based on this information to drive the light-emitting element 132 to move the test card 131 via the second motor 141, so that the imaging device 200 can quickly and accurately acquire the test image of the test card 131.

[0127] Controlling the relative distance between the teleconverter 133, the test card 131, and the mounting part 121 facilitates the testing of some long-focal-length imaging devices 200. Therefore, in this embodiment, the third motor 142 drives the teleconverter 133 to move relative to the test card 131, which can shorten the imaging distance of the imaging device 200, thereby achieving accurate control of the imaging distance.

[0128] Specifically, the driving assembly includes a fourth motor 143, which is connected to the mounting portion 121. The fourth motor 143 drives the mounting portion 121 to move relative to the detection stage 120. It can be understood that in this embodiment, the fourth motor 143 drives the mounting portion 121 to move relative to the detection stage 120 along a first direction (X direction) and / or a second direction (Y direction). This allows the imaging device 200 and the test card 131 on the mounting portion 121 to be aligned, improving detection efficiency.

[0129] In some embodiments, the testing device 100 further includes a housing 110 having a receiving cavity 111, within which the testing stage 120 and the testing assembly 130 are located.

[0130] Both the inspection stage 120 and the test assembly 130 are located within the housing 111 of the enclosure 110. The housing 111 provides various inspection environments to meet the inspection needs of different imaging devices 200. Simultaneously, the test card 131 is movable relative to the mounting section 121, ensuring stable acquisition of the inspection image from the test card 131 by the imaging device 200. Thus, regardless of whether the lens of the imaging device 200 is monocular or multi-purpose, it can be inspected by the inspection device 100. This improves the inspection efficiency of the imaging device 200.

[0131] For example, the enclosure 110 in this embodiment may be partially transparent or opaque. Thus, the enclosure 110 can simulate both the lighting and dark environments in which the imaging device 200 is located. The degree of light transmittance of the enclosure 110 can provide different light intensities to the imaging device 200 to meet its varying light intensity detection requirements.

[0132] For example, the side wall of the housing 110 has an opening that can be opened. This allows the imaging device 200 to be inspected to be easily mounted on the mounting section 121 through the opening in the housing 110. Furthermore, when the inspection table 120 rotates, the position of the mounting section 121 changes, and after the mounting section 121 aligns with the opening, the imaging device 200 to be inspected can be mounted on the mounting section 121 opposite the opening, or an imaging device 200 that has already been inspected can be replaced.

[0133] The detection device 100 also includes a light-absorbing element, which is connected to the inner wall of the housing 110. To prevent the light inside the housing 110 from affecting the detection conditions of the imaging device 200 under inspection, the light-absorbing element is disposed within the receiving cavity 111 and connected to the inner wall of the housing 110. It is understood that along the extension direction of the slide rail 134, the light-absorbing element and the light-emitting element 132 are opposite each other, and the light emitted from the light-emitting element 132 will not be reflected by the light-absorbing element. Thus, the light emitted by the light-emitting element 132 towards the inner wall of the housing 110 will not affect the detection of other mounting parts 121, thereby improving the accuracy of the detection results of the detection device 100.

[0134] For example, the light-absorbing element can be foam.

[0135] The detection device 100 also includes a communication cable. One end of the communication cable is connected to the controller, and the other end is used to connect to the imaging device 200. The communication cable connects the controller and the imaging device 200, improving the stability of information transmission and detection efficiency.

[0136] Furthermore, the second end of the communication cable has at least one connection terminal 150, and the imaging device 200 has an output port, with at least one connection terminal 150 adapted to the output port.

[0137] It is understandable that different models of imaging devices 200 will have different output ports. For example, the output port of the imaging device 200 can be a serial port, a universal serial bus interface, a network port, etc. The communication cable can have one or more connection terminals 150 on the side connected to the imaging device 200. When the communication cable has only one connection terminal 150, the connection terminal 150 of the communication cable is used with the output port of the imaging device 200.

[0138] When there are multiple imaging devices 200 being detected, the second end of the communication cable may have multiple connection terminals 150, each connection terminal 150 being adapted to the output port of the corresponding imaging device 200.

[0139] In some embodiments, the communication cable can be integrated into the various components. For example, the communication cable can be integrated into the mounting part 121, and the connection terminal 150 of the communication cable can protrude from the mounting part 121. In this way, when the imaging device 200 to be tested is mounted on the mounting part 121, it can be connected to the output port of the imaging device 200 through the connection terminal 150 on the mounting part 121.

[0140] See Figure 8 and Figure 9 For some imaging devices 200 that require temperature calibration and testing, a specific temperature radiating element 136 is needed to test the imaging device 200. In some embodiments, the test assembly 130 includes a temperature radiating element 136, which radiates temperature to its external environment so that the imaging device 200 can acquire the radiated temperature and form a detection image. The controller acquires the detection image of the imaging device 200 and analyzes the detection image to form the detection result of the radiated temperature by the imaging device 200.

[0141] In some embodiments, the temperature radiation element 136 is movable relative to the mounting portion, thereby acquiring dynamic temperature detection images and improving the detection efficiency and accuracy of the imaging device 200.

[0142] For example, the test assembly 130 includes a guide rail (not shown) extending toward the test stage 120, and the temperature radiating element 136 is slidably connected to the guide rail. In this embodiment, the guide rail provides a guiding function for the movement of the temperature radiating element 136, ensuring that the temperature radiating element 136 remains aligned with the imaging device 200 mounted on the mounting portion 121 of the test stage 120 during movement, so that the imaging device 200 can accurately acquire the radiated temperature and form a test image.

[0143] In some embodiments, there are multiple test components 130, which are arranged around the periphery of the testing stage 120. Thus, as the testing stage 120 rotates about its axis of rotation, different imaging devices 200 mounted on multiple mounting parts 121 can perform radiation temperature detection at different positions, thereby improving detection efficiency.

[0144] For example, there can be four mounting parts, namely mounting parts 121a, 121b, 121c, and 121d arranged around the rotation axis of the detection table 120. There can be three temperature radiating elements 136, defined as temperature radiating element 136a, temperature radiating element 136b, and temperature radiating element 136c. The three temperature radiating elements 136 are arranged sequentially and spaced around the periphery of the detection table 120. During the rotation of the detection table 120, the mounting part 121a can be positioned sequentially opposite to the temperature radiating elements 136a, 136b, and 136c, so that the imaging device 200 on the mounting part 121a can acquire the radiation temperature of the temperature radiating elements 136a, 136b, and 136c respectively, and form a detection image based on the corresponding radiation temperature. The controller can then calibrate the detection result of the imaging device 200 based on the detection image. In this way, the detection efficiency can be improved.

[0145] It should be noted that the mounting section 121 can mount imaging devices 200 of different models. This application embodiment does not specify the exact model of the imaging device 200.

[0146] It is understandable that as the testing station 120 rotates, the testing process of the imaging equipment 200 on the mounting sections 121b, 121c, and 121d is the same as that on the mounting section 121a, and will not be described in detail here.

[0147] During the testing process, there is a problem that the detection results of the imaging device on the mounting part 121a and the temperature radiation component 136b are inaccurate. In order to troubleshoot the problem, the imaging device 200 is installed on the mounting part 121a and the temperature radiation component 136b are tested two or three more times. If the test results are continuously unqualified, the imaging device 200 on the mounting part 121a does not need to acquire the detection image of the temperature radiation component 136c, thereby improving the accuracy of the test results and the testing efficiency.

[0148] In some embodiments, at least two of the multiple test components 130 have different radiation temperatures of temperature radiators 136. This difference in radiation temperature of the temperature radiators 136 diversifies the detection conditions of the imaging device 200, thereby meeting the detection requirements of the imaging device 200 and improving the accuracy of the detection results.

[0149] For example, among temperature radiators 136a, 136b, and 136c, the radiation temperatures of temperature radiators 136a and 136b may be different. Alternatively, the radiation temperatures of temperature radiators 136a and 136c may be different. Or, the radiation temperatures of temperature radiators 136b and 136c may be different.

[0150] In some embodiments, all temperature radiators 136 may have different radiation temperatures. The arrangement of these radiators with different radiation temperatures is not required in this application embodiment.

[0151] Optionally, multiple temperature radiating elements 136 with different radiation temperatures can be arranged according to the trend of increasing radiation temperature.

[0152] For example, the radiation temperature of the temperature radiating element 136a can be 25℃-70℃, such as 25℃, 30℃, 35℃, 40℃, 45℃, 50℃, 55℃, 60℃, 65℃, 70℃, etc. Any radiation temperature that meets the above numerical range is acceptable and there is no limitation on it.

[0153] Optionally, the radiation temperature of the temperature radiating element 136b can be 55℃-200℃. For example, 55℃, 70℃, 80℃, 90℃, 100℃, 130℃, 160℃, 180℃, 200℃, etc. Any radiation temperature within the above range is acceptable and there are no restrictions.

[0154] Optionally, the radiation temperature of the temperature radiating element 136c can be greater than or equal to 250°C, such as 250°C, 260°C, 280°C, 300°C, 320°C, etc. Any radiation temperature within the above range is acceptable and there are no restrictions.

[0155] When the radiation temperature of temperature radiator 136 is high, in order to reduce the influence of the radiation temperature of temperature radiator 136 on the radiation temperature of other temperature radiators 136, see... Figure 9 In this embodiment of the application, at least one temperature radiating element 136 is provided with a shielding element 137, and the shielding element 137 and the temperature radiating element 136 are movably connected to each other to have a shielding state and a sheltered state; in the shielding state, the shielding element 137 shields the temperature radiating end of the temperature radiating element 136; the shielding element 137 moves relative to the temperature radiating element 136 so that the temperature radiating end of the temperature radiating element 136 is in a sheltered state.

[0156] Thus, in this embodiment of the application, by setting the shielding member 137, the temperature radiation end of the temperature radiation member 136 can be opposite to the corresponding imaging device 200 on the detection stage 120 in an air-protected state, so that the imaging device 200 can acquire the detection image of the radiation temperature. After the detection is completed, the shielding member 137 moves to the shielding state to reduce the influence of the radiation temperature of the temperature radiation member 136 on the radiation temperature of other temperature radiation members 136, thereby improving the accuracy of the detection results of the imaging device 200.

[0157] In some embodiments, the detection device 100 further includes a drive assembly connected to a shielding member 137 to drive the shielding member 137 to switch between a shielding state and an open state relative to the temperature radiation member 136.

[0158] For example, the drive assembly may include a motor, which is connected to the shield 137 to drive the shield 137 to move relative to the temperature radiating element 136. The battery may include a linear motor, etc., and this application embodiment is not limited thereto.

[0159] In some embodiments, the drive assembly also includes a transmission mechanism. The motor is connected to the blocking member 137 through the transmission mechanism. The motor can output circular motion and convert the circular motion into linear motion of the blocking member 137 through the transmission mechanism, so that the blocking member 137 switches between a blocking state and a clearing state.

[0160] Optionally, the motor outputs circular motion and drives the blocking component 137 to rotate through the transmission mechanism, so that the blocking component 137 switches between the blocking state and the clearing state.

[0161] See Figure 9 In some embodiments, the drive assembly includes a reversing valve 144 and a pipeline connection between the reversing valve 144 and the shielding member 137. Thus, in this embodiment, by adjusting the reversing valve 144, the relative position of the shielding member 137 on the temperature radiation member 136 is changed, thereby achieving the switching of the shielding member 137 between a shielding state and an open state.

[0162] The driving medium of the reversing valve 144 can be liquid or gas, such as hydraulic oil or air. This application embodiment does not make specific requirements in this regard.

[0163] When the driving medium of the reversing valve 144 is gas, the driving assembly also includes a gas source dual unit (not shown in the figure). The gas source dual unit is connected to the reversing valve 144 so that the gas pressure can be adjusted through the gas source dual unit to drive the valve core of the reversing valve 144 to change its position, thereby realizing the switching of the blocking member 137 between the blocking state and the evacuation state.

[0164] Furthermore, a control valve is installed on the pipeline of the shielding component 137, so as to control the opening degree of the valve to realize the switching rate of the shielding component 137 between the shielding state and the clearing state, thereby further improving the detection efficiency of the detection equipment 100.

[0165] In some embodiments, the testing equipment 100 further includes a cabinet 160, with the testing platform 120 disposed on top of the cabinet 160; the first motor 140 and the reducer are disposed inside the cabinet 160. Thus, the cabinet 160 provides protection for the first motor 140 and the reducer, preventing their operating temperature from rising due to the radiant temperature of the temperature radiating element 136, thereby ensuring the operational stability and safety of the testing equipment 100.

[0166] It should be noted that the temperature radiating element 136 in the embodiments of this application includes a blackbody radiating element or a heating element with heat, etc., and the embodiments of this application do not make specific requirements in this regard.

[0167] In some embodiments, a balancing support (not shown in the figure) is provided at the bottom of the cabinet 160. By providing the balancing support, the height and balance of the cabinet 160 are adjusted so that the relative position of the test assembly 130 and the imaging device 200 to be tested on the mounting part 121 is accurate, thereby ensuring the accuracy of the results of the imaging device 200 being tested by the testing equipment.

[0168] For example, the balance support includes support rods, support feet, etc. The balance support can be movably connected to the cabinet 160 to facilitate adjustment of the balance support, for example, by threaded connection, telescopic connection, etc.

[0169] In some embodiments, the bottom of the cabinet 160 is provided with casters (not shown in the figure), which facilitates the movement of the testing device 100.

[0170] In some implementations, a control switch 170 is provided on the cabinet 160. The control switch 170 is electrically connected to the controller. When the testing equipment malfunctions, the user can use the control switch 170 to perform an emergency stop operation on the testing equipment 100 to ensure the safety of the testing equipment.

[0171] There can be multiple control switches 170, which are located on the top and / or side of the cabinet 160 for user operation. This application embodiment does not require the specific location of the control switches 170.

[0172] The testing equipment provided in this application includes a testing stage, a controller, and at least one testing component. The testing stage has at least one mounting portion for mounting the imaging device to be tested. The at least one testing component and the at least one mounting portion are correspondingly arranged, with the imaging end of the imaging device facing the testing component and acquiring the test image of the testing component. The controller is electrically connected to the imaging device to be tested and analyzes the test image acquired by the imaging device. The testing equipment can meet the testing needs of various imaging devices and simultaneously test these imaging devices, improving testing efficiency.
