Abstract
Description
Technical Field
[0001] This application relates to the field of photoelectric detection technology, and more particularly to a target wheel system and a method for testing optical parameters thereon. Background Technology
[0002] Optical parameter testing of imaging systems is a fundamental step in the performance calibration of various cameras (camcorders, monitors, thermal imagers, etc.). The basic principle is that a light source passes through a target with a specific pattern to form the image required for the test. This image is then propagated and shaped by a collimator before being captured by the camera. Optical parameters are calculated by analyzing the captured image. Different target patterns are required for different optical parameter testing needs. Therefore, the target needs to be changed during the testing process.
[0003] There are several methods for target replacement, including manual target replacement, manual wheel adjustment, and electric wheel adjustment. One related technology presents an electric wheel target switching structure that uses a worm gear unit to achieve precise target control and positioning, providing the positioning accuracy required for testing. However, in these testing systems, the target at each position needs to be changed in real time according to the product, thus altering the target's orientation and type at each location. Therefore, in traditional testing systems, testing personnel must know the type and orientation of each target at each position to position and set it within the system so that the system can calculate the corresponding optical parameters. This method introduces a significant amount of human intervention, reducing the testing efficiency and increasing the likelihood of errors during testing.
[0004] Therefore, there is an urgent need for a solution to the above problems. Summary of the Invention
[0005] This application proposes a target wheel system and a method for testing optical parameters thereto address the deficiencies of the prior art.
[0006] According to a first aspect of the embodiments of this application, a target wheel system is provided, comprising: The back panel of the outer casing has light-transmitting holes; The target wheel is rotatably mounted on the back plate of the housing. The target wheel is used to carry multiple targets with different test marks. Each target is provided with a target information carrier that records its own identity information. At least one reader is disposed on the back plate of the housing and adjacent to the light-transmitting hole, and is used to read the identity information recorded on the target information carrier on the target when any target moves to the test position corresponding to the light-transmitting hole based on the rotation of the target wheel; The control module, which is communicatively connected to the reader, is used to automatically identify the target type and / or characteristic parameters of the target currently in the test location based on the read identity information, and to automatically configure or select the corresponding test program based on the identification results.
[0007] In some implementations, the target information carrier is an RFID tag, and the reader is an RFID reading antenna.
[0008] In some embodiments, the reader includes a first RFID reading antenna and a second RFID reading antenna, the first RFID reading antenna and the second RFID reading antenna being respectively disposed on the horizontal side and the vertical side of the light-transmitting aperture; The control module is also used to determine the installation direction of the target currently at the test position based on the identity information in the RFID tag read by the first RFID reading antenna or the second RFID reading antenna. The installation direction includes horizontal installation and vertical installation.
[0009] In some embodiments, the target wheel includes a target wheel base plate, which has multiple mounting positions for mounting and fixing each target, and a pivot hole for connecting to a drive mechanism.

[0011] In some embodiments, the control module includes: A storage unit is used to store a target database, which records the correspondence between identity information and target types, feature parameters, and parameter compensation information. The judgment unit is used to query the target database based on the read identity information to obtain the corresponding target type, feature parameters and parameter compensation information, and to determine the target installation direction based on the position of the reader that was successfully read, and output the corresponding target type, feature parameters, parameter compensation information and target installation direction. The testing unit is used to automatically call the corresponding testing program, fill in the feature parameters and parameter compensation information, and control the execution of the testing process based on the target type, feature parameters, parameter compensation information and target installation direction output by the judgment unit.
[0012] According to a second aspect of this application, a method for testing optical parameters is provided, applied to the automated target wheel system described above, comprising: S1: Install multiple targets with different test labels onto the target wheel. Each target is equipped with a target information carrier that records its own identity information. S2: Start the test process, control the target wheel to rotate, and control the current target to rotate to the test position corresponding to the light hole on the back plate of the outer shell in sequence; S3: Read the identity information recorded in the target information carrier of the target currently located at the test position by a reader set on the back plate of the outer shell; S4: Based on the read identity information, automatically determine the target type, characteristic parameters, and target installation direction of the current target; S5: Based on the determined target type, characteristic parameters, and target installation direction, automatically select or configure the corresponding optical parameter test items and execute the test to obtain the test results; S6: Control the target wheel to rotate. When any target rotates to the test position, repeat steps S3 to S5 until all the required targets have been tested.

[0014] In some implementations, after automatically selecting or configuring the corresponding optical parameter test items and executing the test, the process includes: Based on the identity information, the parameter compensation information pre-stored for the target in the target database is invoked to correct the physical deviation of each target.
[0015] In some embodiments, the method further includes: When the target type of the current target does not match the target in the list of optical parameters to be tested based on the read identity information, the target wheel is controlled to skip the current target and rotate to the next target position, and a prompt message is generated and output to characterize the target mismatch. After traversing all target positions, if there are remaining optical parameters to be tested that cannot be completed, a warning message is generated and output to characterize the incomplete test.

[0023] This application discloses a target wheel system and a method for testing optical parameters. This method, based on the target wheel system, aims to provide a readable, unique ID by attaching RFID tags to the target. By placing two RFID tag reading units at the light-transmitting holes, the system can read the target type and orientation at the current target position. Then, the system automatically sets the current test items and parameter indicators in the host computer software and provides compensation parameters corresponding to the current ID product, thereby improving the overall testing accuracy and precision.

[0024] See attached document Figure 1 The diagram shows a schematic representation of a target wheel system according to an embodiment of this application. Figure 1 The left figure shows a top view of the target wheel 1 according to an embodiment of this application. Figure 1 The right figure shows a front view of the housing 3 according to an embodiment of this application, wherein the housing 3 includes a housing back plate 31.
[0025] For example, the target wheel system includes: a housing backplate 31, a target wheel 1, at least one reader, and a control module.
[0026] In some embodiments, the back panel 31 of the outer casing is provided with a light-transmitting hole 32.
[0027] In some embodiments, the target wheel 1 is rotatably mounted on the back plate 31 of the housing. The target wheel 1 is used to carry multiple targets 2 with different test markings. Each target 2 is provided with a target information carrier 21 that records its own identity information (ID information) for identification of the current test target during the test.
[0028] Preferably, the target information carrier 21 is located in the center of each target, and the target information carrier 21 is the target graphic area.
[0029] Preferably, the target information carrier 21 is a specific test pattern designed according to the test requirements; the pattern or feature size of each target is different to meet the test performance requirements of different optical parameters.
[0030] In some implementations, the target information carrier is an RFID tag 22, and the reader is an RFID reading antenna, which can also be understood as an RFID reading chip or antenna circuit.
[0031] Preferred, In some embodiments, the target wheel 1 includes a target wheel base plate 11, which has multiple mounting positions for mounting and fixing each target, and a rotating shaft hole 12 for connecting to a drive mechanism.
[0032] In some embodiments, the target is provided with a mechanical limiting hole, which is used to engage with a corresponding structure on the target wheel so that the target is positioned and installed on the target wheel.
[0033] In some embodiments, at least one reader is disposed on the back panel of the housing and adjacent to the light-transmitting hole, for reading the identity information recorded on the target information carrier on the target when any target moves to the test position corresponding to the light-transmitting hole based on the rotation of the target wheel.
[0034] In some embodiments, the reader includes a first RFID reading antenna and a second RFID reading antenna, which are respectively disposed on the horizontal side of the light-transmitting aperture (see attached figure). Figure 2 (See right image) and vertical side (see attached image) Figure 2 (See the left figure), in which both the first RFID reading antenna and the second RFID reading antenna are fixed by mechanical limiting holes 23.
[0035] Preferably, a first RFID reader chip 33 and a second RFID reader chip 34 for reading RFID information are installed in the horizontal and vertical directions of the light-transmitting hole 32, respectively.
[0036] See attached document Figure 4 The diagram shown illustrates the structure of the target and its disassembled target wheel. Figure 1The disassembled target wheel assembly and support assembly are shown. The left side shows the target wheel body with multiple mounting holes, and the right side shows the semi-circular support. The support has a pre-drilled light-transmitting hole 32 for the outer casing and integrated RFID reading chips 33 and 34. This embodiment of the application is based on this structural design, which facilitates quick assembly and disassembly of the target and ensures that the reading / writing device can accurately cover the target area.
[0037] In some implementations, the control module is communicatively connected to the reader to automatically identify the target type and / or characteristic parameters of the target currently at the test location based on the read identity information, and to automatically configure or select the corresponding test program based on the identification results.
[0038] See attached document Figure 3 As shown, a spatial diagram illustrating the target pose recognition is presented. (See attached diagram.) Figure 3 The diagram illustrates the relative positions of the RFID tag and the reading device under different spatial orientations of the target. The left side of the diagram shows the identification of the target in a vertical position, and the right side shows the identification of the target in a horizontal position. An RFID tag 22 is attached to the target 21. When the target 21 rotates, the RFID tag 22 changes its orientation accordingly. The system determines the pitch angle of the target 21 by detecting changes in the signal.
[0039] In some implementations, the control module is also used to determine the installation direction of the target currently at the test position based on the identity information in the RFID tag read by the first RFID reading antenna or the second RFID reading antenna. The installation direction includes horizontal installation and vertical installation.
[0040] In some implementations, the control module includes a storage unit, a judgment unit, and a testing unit.
[0041] For example, the storage unit is used to store a target database, which records the correspondence between identity information and target type, feature parameters and parameter compensation information.
[0042] For example, the judgment unit is used to query the target database based on the read identity information to obtain the corresponding target type, feature parameters and parameter compensation information, and to determine the target installation direction based on the position of the reader that was successfully read, and output the corresponding target type, feature parameters, parameter compensation information and target installation direction.
[0043] For example, the test unit is used to automatically call the corresponding test program, fill in the feature parameters and parameter compensation information, and control the execution of the test process based on the target type, feature parameters, parameter compensation information and target installation direction output by the judgment unit.
[0044] Specifically, a specific workflow of the target wheel system includes: fixing a series of targets onto the target wheel through mechanical limiting holes 23 according to testing requirements; and, depending on the testing requirements, determining whether horizontal or vertical indicators need to be tested, proceeding according to the attached... Figure 2 The target can be installed in two ways; when the designated target is rotated to the test position (i.e., the light-transmitting hole 32), one of the first RFID reader chip 33 and the second RFID reader chip 34 located on the back plate will overlap with the RFID tag of the target (as shown in the attached diagram). Figure 3 The system reads the ID information from the RFID tag and uploads it to the host computer software. This allows the system to obtain the target type and characteristic parameters being tested. It can also call up parameter compensation information for the target based on the ID information, thereby improving the system's testing accuracy. The system determines whether the target is installed vertically or horizontally based on whether the ID reading circuit is the first RFID reader chip 33 or the second RFID reader chip 34, thus determining the experimental direction of the parameter testing items in the software. Based on the above information, the system automatically selects the test items and fills in the parameters, and then tests the camera under test.
[0045] The core of this application's embodiments lies in integrating RFID technology into the target wheel system of an optical parameter testing system, thereby achieving target identification and automated testing. The key to this technology is identifying the type and parameters of the target currently at the testing position and feeding this information back to the system software to automate the process. The identification of target type and parameters in this application's embodiments can also be achieved in other ways, including but not limited to the following: directly photographing and recognizing the exposed target and feeding the results back to the software; this method requires additional cameras and algorithms, resulting in higher costs; encoding the target surface with images (such as barcodes, QR codes, etc.) and identifying the target by scanning the image at a specific location; this method requires introducing additional lighting sources into the system to perform the scanning operation, posing a risk of affecting performance testing; or using electrical solutions, such as contact resistance or capacitance, requiring the establishment of an internal test circuit.
[0046] This embodiment of the application achieves automatic identification and judgment of the target's real-time attitude (vertical / horizontal) by attaching RFID tags to the target body vertically and horizontally, respectively, in conjunction with an RFID reader and antenna fixed on the bracket. This eliminates the need for manual intervention or additional sensors, significantly improving the automation level and response speed of target reporting. The multiple mounting holes on the target wheel in this embodiment allow for flexible adjustment of the target installation position, adapting to different training distances and angles. The explosive split structure design facilitates quick disassembly and maintenance of the target wheel, while optimizing the layout of the reading and writing devices to ensure complete signal coverage and enhance system stability and environmental adaptability.
[0047] See attached document Figure 6 As shown in the embodiments of this application, the method for testing optical parameters is applied to the automated target wheel system described above, and includes the following steps S1 to S6.
[0048] S1, multiple targets with different test markings are installed on the target wheel, and each target is equipped with a target information carrier that records its own identity information.
[0049] Specifically, in this embodiment of the application, step S1 includes: determining the target series required for testing based on the indicators to be tested by the camera under test (the number of tests is determined by the number of targets that can be installed on the target wheel at the same time); and installing the targets on the target wheel and fixing them.
[0050] S2, start the test process, control the target wheel to rotate, and control the current target to rotate to the test position corresponding to the light-transmitting hole on the back plate of the shell in sequence.
[0051] Specifically, in this embodiment of the application, step S2 includes: after starting the automated test program, the target wheel rotates the first target to the test position, and at this time the ID signal of the target is read out.
[0052] S3, the identity information recorded by the target information carrier of the target currently located at the test position is read by a reader set on the back panel of the housing.
[0053] Specifically, in this embodiment of the application, step S3 includes: uploading the ID information to the host computer software, thereby obtaining the target type and characteristic parameters being tested at this time, and calling the parameter compensation information for the target based on the ID information, thereby improving the testing accuracy of the system.
[0054] S4 automatically determines the target type, characteristic parameters, and target installation direction of the current target based on the read identity information.
[0055] In some implementations, the automatic determination of the target type, feature parameters, and target installation direction of the current target based on the read identity information includes: matching the read identity information with a target database, querying and obtaining the target type and feature parameters bound to the identity information; and determining whether the current target installation direction is horizontal or vertical based on the identity information successfully read by the reader located on the horizontal or vertical side of the light aperture.
[0056] Specifically, in this embodiment of the application, step S4 includes: determining whether the current target installation status is vertical or horizontal based on whether the circuit for reading the ID is the first RFID reading chip 33 or the second RFID reading chip 34, thereby determining the experimental direction of the parameter test items in the software.
[0057] S5, based on the determined target type, characteristic parameters, and target installation direction, automatically selects or configures the corresponding optical parameter test items and executes the test to obtain the test results.
[0058] In some implementations, after automatically selecting or configuring the corresponding optical parameter test items and performing the test, the process includes: based on the identity information, calling the parameter compensation information pre-stored for the target in the target database to correct the physical deviation of each target.
[0059] Specifically, in this embodiment of the application, step S5 includes: automatically running the corresponding test program according to the target type and feature parameters, completing the test and saving the results.
[0060] S6, control the target wheel to rotate. When any target rotates to the test position, repeat steps S3 to S5 until all the required targets are tested.
[0061] In some implementations, the method further includes: When the target type of the current target does not match the target in the list of optical parameters to be tested based on the read identity information, the target wheel is controlled to skip the current target and rotate to the next target position, and a prompt message is generated and output to characterize the target mismatch. After traversing all target positions, if there are remaining optical parameters to be tested that cannot be completed, a warning message is generated and output to characterize the incomplete test.
[0062] Specifically, in this embodiment of the application, step S6 includes: the target wheel rotates the second target to the test position, and the above test process is repeated.
[0063] This completes the parameter testing for each target position, thus automating the optical parameter testing process for the camera under test.
[0064] To further illustrate the effects of the embodiments of this application, the following exemplary description and demonstration are provided based on Embodiment 1 and Embodiment 2.
[0065] Example 1 illustrates an implementation method for automatically identifying and adjusting parameters for optical parameter testing. The specific operation includes: the camera under test is an infrared thermal imager, and the testing system is an optical parameter testing system with a focal length of 3000 mm; a four-bar target with a slit width of 1.5 mm is fixed at position 1 of the target wheel, placed vertically; a crescent-shaped target is fixed at position 2, also placed vertically; after installation and closing the target wheel housing, the system software rotates the target wheel to position 1; at this time, the RFID tag of the four-bar target is aligned with the reading circuit 34; the information from the RFID circuit 34 is read and transmitted to the system software; the software confirms based on the ID information that the target at the measurement position (position 1) is a four-bar target with a slit width of 1.5 mm; using the built-in system focal length parameters, the spatial frequency used in this test is calculated to be 1.0. cy / mrad; Based on this information, the user is recommended to perform minimum resolvable temperature difference (MRTD) or equivalent length test; The user selects MRTD test according to their needs, the program runs automatically, analyzes the four-bar target image captured by the thermal imager, calculates the MRTD index at the current spatial frequency, and outputs the calculation result. The system software is used to rotate the target wheel to position 2; At this time, the RFID tag of the crescent target is facing the reading circuit (34); The reading circuit (34) reads the RFID information and transmits it to the system software; The software confirms that the target located at the measurement position (position 2) is a crescent target and is placed vertically according to the ID information; Based on this information, the user is recommended to perform signal transfer function (SiTF) or modulation transfer function (MTF) test; Since the tag information is sent by the reading circuit (34), the result provided by the MTF test is the horizontal MTF. The user selects MTF test according to their needs; The program runs automatically, analyzes the crescent target image captured by the thermal imager, finds the edge and calculates the MTF curve of the thermal imager, and outputs the calculation result.
[0066] Example 2 illustrates an implementation of an automated optical parameter testing process. The specific operation includes: the camera under test is an infrared thermal imager; the testing system is an optical parameter testing system with a focal length of 3000 mm; the optical parameters to be tested include: Signal Transfer Function (SiTF), 3D-Noise, Equivalent Noise Temperature Difference (NETD), Minimum Resolvable Temperature Difference (MRTD), Minimum Detectable Temperature Difference (MDTD), and Modulation Transfer Function (MTF). The automated optical parameter testing is initiated in the system software, and the items to be tested are selected. Multiple targets matching the corresponding parameters are installed on the target wheel, without regard to the order. These targets include a crescent target for testing SiTF and MTF, a completely black target for testing 3D-Noise, a four-bar target for testing MRTD, and a circular hole target for testing MDTD. Place the camera under test and start the test process; the target wheel rotates the first target to the measurement position under the control of the motor, and the target ID at the measurement position is identified by the reading circuits (33) and (34); the corresponding target type and characteristic parameters are imported into the system according to the target ID, and the test item corresponding to the target is selected according to the list of optical parameters to be tested; the result characteristic parameters and test data are analyzed and processed, the final test index is calculated and the result is saved; rotate to the next target position, and the target ID at the measurement position is identified by the reading circuits (33) and (34); the corresponding target type and characteristic parameters are imported into the system according to the target ID, and the test item corresponding to the target is selected according to the list of optical parameters to be tested; the result characteristic parameters and test data are analyzed and processed, the final test index is calculated and the result is saved; repeat the above operation until all test items of optical parameters to be tested are completed. If a target mismatch occurs during the process, the current target is skipped and a prompt message is provided; if parameters still fail to be tested after all target positions have been used, a warning message is provided.
[0067] Existing optical parameter testing methods heavily rely on the operator's operation. The operator needs to manually install the target onto the target wheel, select a position in the software, rotate it to the test position, manually select the test program corresponding to the target position, and fill in the target's characteristic parameters to ensure the accuracy of the test results. This process carries the risk of human error and has low testing efficiency.
[0068] This application embodiment uses the unique ID information of each target to automatically read the ID information and orientation information of the test target, thereby automatically extracting relevant information from the database and performing corresponding parameter tests. This method can achieve complete automation of optical parameter testing, eliminating the need for manual operation. At the same time, since the target wheel can provide multiple target positions for placing different targets, the measurement process of multiple optical parameters of the camera can be fully automated by setting the program, which greatly improves testing efficiency and reduces the professional requirements of testing personnel.
[0069] The above statements are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any simple modifications, changes, and equivalent changes made by those skilled in the art to the above embodiments based on the technical essence of the embodiments of this application within the scope of the technology disclosed in the embodiments of this application shall still fall within the protection scope of the technical solution of the embodiments of this application.

The method for testing optical parameters according to claim 7, characterized in that, After automatically selecting or configuring the corresponding optical parameter test items and executing the test, the following steps are included: Based on the identity information, the parameter compensation information pre-stored for the target in the target database is invoked to correct the physical deviation of each target.
10. A method for testing optical parameters according to claim 7, characterized in that, The method further includes: When the target type of the current target does not match the target in the list of optical parameters to be tested based on the read identity information, the target wheel is controlled to skip the current target and rotate to the next target position, and a prompt message is generated and output to characterize the target mismatch. After traversing all target positions, if there are remaining optical parameters to be tested that cannot be completed, a warning message is generated and output to characterize the incomplete test.
