Description

A long-distance measurement system including a collimator and a collimator configured to receive radiation emitted from a light source.

[0001] The present invention relates to a long-distance measurement system including a collimator and a collimator configured to receive radiation emitted from a light source.

[0002] In the past, a calibration system was widely used to calibrate the internal parameters of a camera or evaluate image characteristics by placing a reference target at a certain distance and manually photographing it.

[0003] However, this method requires a large space because it requires a physical measurement distance, and has the problem of low efficiency in changing distance conditions or performing repeated measurements.

[0004] In addition, some systems have the disadvantage of being difficult to flexibly respond to various distance and viewing angle conditions because they only provide a shooting environment under fixed distance conditions using a manual or fixed collimator.

[0005] The present invention seeks to provide a system capable of repeatable and automated calibration and image correction at multiple distance conditions by including a motor-controlled collimator capable of continuously adjusting a diopter value.

[0006] The present invention seeks to implement an environment in which image data can be collected from multiple angles and optical evaluation based on field of view can be precisely performed through a rotatable or multi-positionable collimator configuration.

[0007] The present invention seeks to provide a precision optical system capable of simulating the focal length, distortion characteristics, correction parameters, etc. of a camera even in an environment other than actual long-distance shooting conditions.

[0008] The present invention relates to a long-distance measurement system including a collimator, comprising: a collimator configured to receive radiation emitted from a light source; and a camera configured to receive parallel light output from the collimator and generate image data based on the received parallel light; wherein the collimator comprises: a collimator lens unit configured to convert the radiation into the parallel light; a collimator light source device configured to control a diopter value by changing a position and angle of a ray of radiation incident on the collimator lens unit; and a collimator control unit configured to control a position of the collimator light source device.

[0009] Additionally, the collimator includes a motor-controlled collimator.

[0010] In addition, the collimator light source device is installed so as to be movable in a vertical direction, and is configured so that the position and angle of the radiation light incident on the collimator lens part change according to the vertical movement of the collimator light source device.

[0011] In addition, the collimator control unit is configured to continuously change a diopter value corresponding to the inspection distance by controlling the position of the collimator light source device.

[0012] In addition, the collimator further includes a collimator rotation frame, and the collimator rotation frame is configured to rotate at a predetermined angular interval.

[0013] Additionally, the collimator control unit is configured to control the rotation of the collimator rotation frame.

[0014] In addition, the collimator is configured to be one or more and is configured to face different directions at multiple points on an arc or sphere centered on the camera.

[0015] The present invention relates to a collimator configured to receive radiation emitted from a light source, comprising: a collimator lens unit configured to convert the radiation into parallel light; a collimator light source device configured to control a diopter value by changing the position and angle of a ray of radiation incident on the collimator lens unit; and a collimator control unit configured to control the position of the collimator light source device.

[0016] In addition, the collimator light source device is installed so as to be able to move in the vertical direction, and the position and angle of the radiation light incident on the collimator lens unit change according to the movement of the light source.

[0017] Additionally, the collimator includes a motor-controlled collimator.

[0018] Additionally, the collimator control unit is configured to control the position of the collimator light source device based on a diopter value corresponding to the movement position of the collimator light source device.

[0019] In addition, the collimator rotation frame is further included, and is configured to rotate about an arbitrary central axis by the collimator rotation frame.

[0020] The present invention provides the effect of increasing space efficiency by enabling simulation of various distance conditions without implementing an actual long-distance environment.

[0021] The present invention provides the effect of enabling precise analysis of distance-based image characteristics, resolution, distortion, etc. of a camera by enabling continuous or sequential diopter adjustment using a motor-controlled collimator.

[0022] The present invention provides the effect of enabling complex optical performance evaluation by enabling measurement under multi-angle viewing conditions using a rotating frame or multi-array structure.

[0023] The present invention provides an effect of improving repeatability and position reproducibility when distance conditions change through precise control of a light source device and a control unit, which are components of a motor-controlled collimator.

[0024] The present invention enables automatic measurement for multiple distance and viewing angle conditions through a structure that can utilize multiple motor-controlled collimators, and since time-division or parallel control is possible, it provides the effect of increasing the measurement speed and processing efficiency of a long-distance measurement system including a collimator.

[0027] FIG. 3 is a schematic diagram of a multi-angle field-of-view based motor-controlled collimator according to one embodiment of the present invention.

[0028] Specific details of the embodiments are included in the detailed description and drawings.

[0029] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals designate like elements throughout the specification.

[0030] FIG. 1 is a drawing for explaining each component of a long-distance measurement system including a collimator according to the present invention.

[0031] As illustrated in FIG. 1, a long-distance measurement system (10) including a collimator includes a measurement object (OB), a collimator (200), a camera (100), and a processing device (300). The long-distance measurement system (10) including a collimator can simulate an actual long-distance environment, and thus, image measurement and calibration for various distance conditions within a limited space are possible. Specifically, the collimator (200) of the present invention includes a motor-controlled collimator. The motor-controlled collimator can precisely adjust the parallelism and focal position of the emitted light by electrically controlling the position of the light source device inside the collimator. In particular, by changing the up-and-down position of the light source device, the incident position and angle of the light passing through the lens unit change, and accordingly, the diopter value can be continuously changed. Therefore, the motor-controlled collimator can simulate virtual distance conditions without physical distance movement.

[0032] Object of Measurement (OB)

[0033] As illustrated, the measurement object (OB) is an object that serves as a calibration reference for a long-distance measurement system (10) including a collimator, and serves to precisely evaluate the image performance of a camera (100) or provide reference data for performing optical correction. The measurement object (OB) may be implemented in various forms such as a transparent substrate, a reflective sheet, an optical target, etc., and is generally composed of a flat transparent substrate combined with a backlight or a chart formed with a specific optical pattern.

[0034] Specifically, the measurement target (OB) can be illuminated by a backlight source installed internally or at the rear, thereby radiating a high-contrast reference pattern externally, or by reflecting or scattering the irradiated light from the external light source to provide optical information. For example, a substrate on which various types of reference patterns, such as a cross-hatch, a circular target, a resolution chart (MTF chart), and a field-of-view pattern, are printed or etched can be used, and these are utilized for camera focus alignment, resolution measurement, distortion analysis, etc.

[0035] In this embodiment, as illustrated in Fig. 1, radiant light (L1) is emitted from a measurement object (OB). This radiant light (L1) enters the incident surface of a collimator lens unit (210), is converted into parallel light, and then transmitted toward a camera (100). The measurement object (OB) can be implemented as a self-luminous type such as an OLED or built-in LED, or a non-self-luminous type such as an external backlight lighting method, depending on the light emission method, and can maintain high light uniformity and contrast ratio even in a practical long-distance simulation environment.

[0036] synchrotron radiation (L1)

[0037] The emitted radiation (L1) is light generated from the measurement object (OB) and is an optical signal including a reference image or pattern image generated by the surface of the measurement object or a built-in light source. The emitted radiation (L1) is emitted from the front or rear of the measurement object and guided to the incident surface of the collimator (200) in a straight or reflected form.

[0038] Synchrotron radiation (L1) typically consists of high-contrast patterned light uniformly irradiated by a flat light source such as a backlight, LED, or OLED, and may cover a specific wavelength band or a wide spectrum. Furthermore, since synchrotron radiation (L1) contains highly reproducible reference optical information for multiple viewing angles or distance conditions, it serves as a key optical input that determines the image analysis accuracy and repeatability of the camera (100).

[0039] In this embodiment, the radiant light (L1) is incident on the collimator (200), and then converted into parallel light (L2) having a constant parallelism through light reception and optical processing by the collimator lens unit (210). Therefore, the radiant light (L1) is not simply illumination light, but functions as a precise optical signal containing reference image information in a long-distance simulation environment, and directly affects the measurement accuracy and resolution analysis of the entire system.

[0040] According to the present invention, the collimator (200) is composed of a composite optical module including a collimator lens unit (210), a collimator light source device (220), a collimator control unit (230), and a collimator rotation frame (240).

[0041] Collimator lens section (210)

[0042] According to one embodiment of the present invention, the collimator lens unit (210) is an optical conversion module that performs a function of converting incident radiation light (L1) into a light ray (L2) by converging or parallelizing it at a certain angle. The lens unit (210) is composed of a plurality of optical lenses, and these lenses are precisely arranged based on the optical axis, so that the optical convergence condition or parallel condition can be satisfied according to the angle and position of the incident light. Specifically, the collimator lens unit (210) refracts the radiation light (L1) entering from the measurement object (OB) along a series of optical paths, and adjusts the divergence angle or convergence angle of the light, thereby aligning the output light with respect to the incident surface of the camera (100) and processing it to have a certain degree of parallelism. In this process, each lens is designed to have a specific focal length, refractive index, and radius of curvature, so as to precisely correct the path of the incident light and minimize distortion.

[0043] According to one embodiment of the present invention, the collimator lens unit (210) can generally be composed of two or more convex lenses or a convex-concave pair, and can include an aspherical lens or a precision lens group with an optical coating applied as needed. Such a structure can implement optimal parallel light (L2) output conditions depending on the wavelength characteristics or irradiation angle of the radiation light (L1).

[0044] Collimator light source device (220)

[0045] According to one embodiment of the present invention, the collimator light source device (220) is installed inside the collimator (200) and serves to emit light or generate reference light. In addition, the collimator light source device (220) can assist light emitted from the measurement object (OB) or provide a reference pattern through self-luminescence. In addition, the collimator light source device (220) can generally be configured with a backlight, an LED array, a laser diode (LD), or the like.

[0046] According to one embodiment of the present invention, the collimator light source device (220) includes a plurality of light-emitting elements and a diffusion plate or a light-homogenizing film, and can irradiate uniform light to the entire collimator lens unit (210). In addition, the collimator light source device (220) is mounted so as to be vertically movable by a motor or an actuator, thereby changing the light-emitting position. As the light-irradiating position of the collimator light source device (220) changes, the lens incidence angle changes, and as a result, the parallelism and focus position of the output light are changed.

[0047] According to one embodiment of the present invention, the collimator light source device (220) receives a control signal from the collimator control unit (230) and moves to a predetermined position according to distance conditions. The position of the collimator light source device (220) is determined according to predefined distance-diopter mapping information, thereby enabling implementation of virtual inspection distance conditions.

[0048] According to one embodiment of the present invention, the collimator light source device (220) is controlled to move with fine resolution when continuous distance changes are required, thereby enabling precise distance simulation. Furthermore, the collimator light source device (220) can be repeatedly driven in response to multiple viewing angles or multiple distance conditions.

[0049] Collimator control unit (230)

[0050] According to the present invention, the collimator control unit (230) is composed of a control circuit or microcontroller unit (MCU) that controls the operation of the collimator (200). The collimator control unit (230) controls the vertical movement of the collimator light source device (220) to adjust the incident position and angle of the light passing through the lens unit (210). In addition, the collimator control unit (230) precisely adjusts the position of the light source device (220) to correspond to a predetermined diopter value based on a control command received from the outside or distance-focus correspondence data stored in advance.

[0051] According to one embodiment of the present invention, the collimator control unit (230) calculates the movement distance, speed, direction, etc. of the light source device (220) in real time and transmits a driving signal to a motor or actuator. In addition, the collimator control unit (230) can detect the current light source position using a feedback means such as a position sensor or encoder and perform closed-loop control until the target position is reached.

[0052] According to one embodiment of the present invention, when multiple collimators (200) are used, the collimator control unit (230) can minimize optical interference and perform efficient sequence control through time-division control or parallel control between each collimator. In addition, the collimator control unit (230) can control the collimator (200) so that repeated measurements can be performed for multiple distance and multiple angle conditions according to preset simulation conditions.

[0053] Collimator Rotating Frame (240)

[0054] According to the present invention, the collimator rotation frame (240) is a structure that rotatably supports the collimator (200). The collimator rotation frame (240) arranges the collimator (200) based on a certain radius, and can precisely rotate it along the rotation center axis. In addition, the collimator rotation frame (240) can be operated by mounting one collimator (200) or fixing a plurality of collimators (200). In addition, the collimator rotation frame (240) can be linked with an angle adjustment mechanism or a motor driving device to control the rotational position of the collimator (200). Specifically, the collimator rotation frame (240) divides the rotational position into predetermined angular intervals, for example, 5 degrees or 10 degrees, to enable multi-angle measurement.

[0055] According to the present invention, the collimator rotation frame (240) may include a high-precision bearing or a precision guide structure so that the optical axis alignment is maintained even when rotating. In addition, the collimator rotation frame (240) can precisely control the rotation angle, speed, stop position, etc. in conjunction with the collimator control unit (230). Specifically, the collimator rotation frame (240) sets an angle so that it can receive the radiation light (L1) from different directions of the measurement object (OB) depending on the rotation position. In addition, the collimator rotation frame (240) may be arranged to rotate along a constant arc or hemispherical path centered on the camera (100).

[0056] Parallel light (L2)

[0057] According to the present invention, parallel light (L2) emitted from the collimator (200) reaches the incident surface of the camera (100) while maintaining a constant directionality and parallelism. The parallel light (L2) is light precisely processed by the collimator (200) and simulates the same conditions as when emitted from a specific virtual distance. The camera (100) is composed of an image acquisition module including a lens and an image sensor, and receives the parallel light (L2) and generates corresponding image data (D). The camera (100) can precisely measure the resolution, contrast ratio, distortion information, etc. of the image signal according to the field of view, focal length, irradiance, etc. of the incident light. The camera (100) transmits the acquired image data (D) to an internal image processor or an external processing device (300) and utilizes it for distance-based image analysis and calibration processing. Therefore, the parallel light (L2) emitted from the collimator (200) can function as a reference light for generating image data (D) in the camera (100).

[0058] Camera (100)

[0059] The camera (100) is composed of an image acquisition module including a digital image sensor, and receives parallel light (L2) to generate corresponding image data. The generated image data (D) is transmitted to a processing device (300) and used for various post-processing tasks such as distance analysis, lens correction, and field of view distortion evaluation.

[0060] Processing unit (300)

[0061] According to one embodiment of the present invention, the processing device (300) performs a function of analyzing calibration results and evaluating image quality based on image data (D) received from the camera (100). Specifically, the processing device (300) can recognize reference patterns or marker information within the image data (D) and perform post-processing operations such as estimating internal parameters of the camera, verifying optical axis alignment, and evaluating resolution.

[0062] According to one embodiment of the present invention, the processing device (300) can calculate key correction parameters such as Focal Length, Distortion Coefficient, and Optical Center from image data acquired during the calibration process. In addition, the processing device (300) can determine whether the correction quality is within a reference range based on the calculation results, and output a control signal so that the correction algorithm can be reapplied if necessary.

[0063] According to one embodiment of the present invention, the processing device (300) can quantitatively analyze field of view distortion, resolution change, or nonlinear correction error by comparing a plurality of collected image frames. In addition, the processing device (300) can communicate with the camera (100) or collimator control unit (230) and adjust parameters such as distance setting values ​​or light source positions according to the corrected results.

[0064] According to one embodiment of the present invention, the processing device (300) can visually provide the user with the analysis results of the image data (D) or store the quality evaluation indicators in a log format to enable subsequent review. Furthermore, the processing device (300) can perform comparative evaluations not only for single-distance conditions, but also for multi-diopter conditions or multi-angle viewing conditions.

[0065] That is, although the processing device (300) does not perform direct control linkage with the collimator (200), which is a core component of the present invention, it can contribute to maintaining the precision and consistency of the entire calibration flow. Therefore, the processing device (300) is a component that is responsible for post-processing and quality analysis of image data in a long-distance measurement system (10) including a collimator, and plays a supplementary role in ensuring the accuracy and stability of the calibration results.

[0066] The long-distance measurement system (10) according to the present embodiment processes the radiation (L1) emitted from the measurement target (OB) through a collimator (200) to convert it into parallel light (L2), converts it into image data (D) through a camera (100), and then performs precise distance-based calibration and image analysis through a processing device (300), thereby enabling practical long-distance measurement even in a limited space.

[0067] FIG. 2 is a schematic diagram showing the configuration of a motor control collimator according to one embodiment of the present invention.

[0068] As illustrated in FIG. 2, the collimator (200) includes a collimator light source device (220) and a collimator lens unit (210), and is configured to convert incident radiation light into parallel light and transmit it to the camera (100), thereby enabling flexible adjustment of the virtual inspection distance (diopter).

[0069] The collimator light source device (220) can receive light (L1) emitted from an external measurement target (OB) or can operate as a reference light source by emitting light on its own, and is arranged to be movable in the vertical direction (up and down). This light source device (220) is controlled by a motor or an actuator, so that as the light source position moves up and down with respect to the collimator lens unit (210), the position and angle of the light incident on the lens change. As a result, the parallelism and focus position of the light passing through the lens unit change, and accordingly, the virtual inspection distance of the entire system, i.e., the diopter value, changes.

[0070] The collimator lens unit (210) positioned at the bottom is composed of a plurality of optical lenses and is configured to convert light irradiated from the light source device (220) or externally introduced radiation light (L1) into parallel light (L2) along a certain optical axis and output it. The lens unit (210) is installed at a fixed position and is designed to induce a change in focal length simply by adjusting the position of the light source device (220).

[0071] In this embodiment, the collimator (200) can precisely control the movement of the collimator light source device (220) according to the control signal of the internal collimator control unit (230), thereby automatically realizing the virtual inspection distance conditions set by the user. For example, the corresponding diopter value according to the vertical movement range of the light source device (220) can be calculated by a predefined distance-focus relationship table or operation algorithm, and thus simulations for multiple distance conditions can be performed continuously or sequentially.

[0072] The configuration of the collimator (200) as described above eliminates constraints such as securing a physical distance, large setup space, and equipment movement required in existing long-distance measurement systems, and enables precise and repeatable image measurement and calibration for multiple distance conditions even in limited spaces. In particular, it can be applied to various purposes such as evaluating the resolution, distortion characteristics, and focus accuracy of a camera (100) according to various focal length conditions, verifying an auto-focus algorithm, and testing multi-distance-based optical modules.

[0073] Furthermore, the collimator (200) is structured to enable continuous distance switching under multiple diopter conditions, in addition to single-distance measurements, thereby offering outstanding advantages in terms of repeatability and time efficiency. In other words, the long-distance measurement system (10) including the collimator according to the present invention can be utilized in various industrial settings, such as optical component production processes, quality assessments, and research and development testing environments, and can provide substantial technological contributions.

[0074] FIG. 3 is a schematic diagram of a multi-angle field-of-view based motor-controlled collimator according to one embodiment of the present invention.

[0075] As illustrated in FIG. 3, a plurality of collimators (200) are arranged to form different viewing angles centered on the camera (100), and each collimator is configured to receive radiation (L1) from a measurement object (OB), convert it into parallel light (L2), and acquire image data (D) by making the parallel light (L2) incident on the camera (100).

[0076] An embodiment of rotating one collimator (200)

[0077] In one embodiment, a single collimator (200) is mounted on a collimator rotation frame (240) and can change the field of view at multiple angles while rotating around a central axis while maintaining a constant radius. The rotational position is precisely controlled by a collimator control unit (230), and sequential rotation is performed by dividing it into predetermined angular resolutions, such as intervals of 5 degrees or 10 degrees.

[0078] The collimator (200) receives the radiated light (L1) emitted from the measurement target (OB) at each rotational position, converts it into parallel light (L2) through the collimator lens unit (210), and causes it to be incident on the camera (100). The camera (100) receives the light incident from the corresponding direction, generates corresponding image data, and transmits it to the processing device (300). The processing device (300) can comprehensively analyze the image data by viewing direction and perform various post-processing tasks such as multi-angle calibration, viewing distortion correction, and viewing angle performance evaluation.

[0079] In this way, the method of rotating a single collimator (200) is a structure that can cover multiple viewing conditions using a single device, minimizing the overall volume of the system and reducing structural complexity, while providing the flexibility to realize image measurements for a wide range of directions. In particular, since the collimator control unit (230) can control the rotational position and precisely repeat the operation, it can effectively perform repeated measurements or error correction for each viewing angle condition.

[0080] Embodiment in which multiple collimators (200) are fixed

[0081] In another embodiment, a plurality of collimators (200) may be arranged at fixed positions according to a predefined viewing angle interval. For example, by fixing collimators (200) at multiple points on an arc or sphere centered on the camera (100) so that they each face different directions, a structure is formed that can observe the measurement object (OB) under various viewing angle conditions. This fixed multiple arrangement method is advantageous in terms of measurement repeatability and time efficiency because parallel light (L2) can be incident on the camera (100) from multiple directions simultaneously or sequentially without a rotating mechanism.

[0082] Each collimator (200) operates independently and can be configured to have identical or different diopter conditions. Some collimators can be configured to simulate identical distance conditions, while others can be configured to reproduce different focal length conditions, thereby enabling the camera (100) to efficiently acquire image data under various distance and direction conditions. In addition, each collimator can be independently controlled and, through interworking with the processing device (300), can emit parallel light in a specific order or in parallel, thereby allowing for flexible application according to the user's measurement purpose and procedure.

[0083] With this configuration, the long-distance measurement system (10) including the collimator can be effectively utilized not only for multi-angle-based calibration, but also for high-dimensional optical test environments such as non-contact 3D shape measurement, resolution analysis by viewing angle, and 3D environment simulation. In addition, a method of temporally dispersing each light emission point or controlling the illumination intensity and frequency can also be implemented to prevent optical interference between multiple collimators.

[0084] Therefore, the fixed multi-position method according to the present embodiment can provide practical technical effects in various application fields such as automated image inspection, lens quality evaluation, and multi-distance based image algorithm learning by enabling fast and precise image acquisition for multiple field of view conditions while maintaining the structural stability and precise control capability of the long-distance measurement system (10) including the collimator.

[0085] As illustrated in FIG. 3, the collimator (200) of the present invention can go beyond simple distance adjustment and simultaneously perform a variety of viewing directions and optical simulations. Images collected from multiple viewing angles can be comprehensively analyzed by a processing device (300) and utilized for various purposes, such as distortion correction for the entire field of view of the camera (100), alignment accuracy evaluation, or 3D reconstruction.

[0086] The scope of the present invention is not limited to the embodiments described above, but can be implemented in various forms within the scope of the appended claims. It is contemplated that the scope of the claims encompasses various modifications that can be made by anyone skilled in the art without departing from the spirit of the invention as claimed.
