Description

Technical Field

[0001] This disclosure relates to the field of testing technology, and more specifically, to a glare testing device. Background Technology

[0002] In related technologies, with the continuous development of terminal devices, the cameras equipped on these devices are becoming increasingly complex, making glare more likely to occur. Therefore, there is an urgent need to design a device capable of testing for glare. Utility Model Content

[0003] The purpose of this disclosure is to provide a glare testing device that can test the glare phenomenon of a camera and has a wide testing range.

[0004] To achieve the above objectives, this disclosure provides a glare testing device, comprising:

[0005] Base;

[0006] A clamp is disposed on the base, the clamp being used to hold the camera and move the camera to a preset center position;

[0007] Light source; and

[0008] A driving mechanism is disposed on the base. The driving mechanism is configured to drive the light source to move on a spherical surface with a preset center as the center, and to make the light source emit light toward the preset center.

[0009] Through the above technical solution, in the glare testing device provided in this disclosure, when testing the glare phenomenon of a camera, the camera can first be placed on a clamp and fixed by the clamp. During this process, the clamp can be used to move the camera, positioning it at a preset spherical center. Subsequently, the drive mechanism can drive the light source to move. When the light source is on a spherical surface with the preset spherical center as its center, it emits light towards the preset spherical center, i.e., emits light towards the camera. Thus, the glare phenomenon of the camera can be tested. Since the drive mechanism of this disclosure can move the light source on a spherical surface with the preset spherical center as its center, the drive mechanism can simultaneously change the longitude and latitude of the light source. Therefore, it is suitable for illuminating the camera from different positions and / or different incident angles, thereby effectively improving the testing range of the glare test.

[0010] In some possible implementations, the driving mechanism includes a first driving structure and a second driving structure connected to each other. The first driving structure drives the light source to rotate about a first axis, and the second driving structure drives the light source to rotate about a second axis, wherein the first axis and the second axis are perpendicular to each other. Thus, the driving mechanism can simultaneously change the longitude and latitude of the light source.

[0011] In some possible implementations, the driving mechanism further includes a third driving structure connected to the second driving structure and configured to ensure that the distance between the light source and the preset center of the sphere is equal to the radius of the sphere centered at the preset center. This allows the light source to remain stationary on the sphere, even if all test points of the light source are located on the sphere.

[0012] In some possible implementations, the first axis is arranged horizontally, the first drive structure is spaced apart from the clamp, and the direction of the spacing between the first drive structure and the clamp is parallel to the extension direction of the first axis. This facilitates the arrangement of the drive mechanism and the clamp, and the third drive structure is at least used to compensate for the spacing between the first drive structure and the clamp, as well as the initial height difference between the first drive structure and the preset center of the sphere.

[0013] In some possible implementations, the first axis and the second axis are spaced apart, and the direction of the spacing between the first axis and the second axis is perpendicular to the first axis and the second axis. This facilitates the connection between the first drive structure and the second drive structure, avoids the second drive structure being directly connected to the drive shaft of the first drive structure, and the third drive structure is at least used to compensate for the gap between the first axis and the second axis.

[0014] In some possible implementations, the third drive structure includes at least two sequentially connected swing arms. The two swing arms at the ends are respectively connected to the second drive structure and the light source. The swing axis of the swing arms is parallel to the second axis, and each swing arm is connected to a motor. Thus, by arranging at least two swing arms, the light source can be kept on the spherical surface and emit light towards a predetermined center of the sphere.

[0015] In some possible implementations, the number of swing arms is at least three segments, comprising a first swing arm, a second swing arm, and a third swing arm connected sequentially, wherein the length of the second swing arm is greater than the length of the first swing arm, and / or the length of the second swing arm is greater than the length of the third swing arm. Therefore, by making the second swing arm longer, it can be used more effectively to compensate for the gap between the first drive structure and the fixture, and / or to compensate for the gap between the first axis and the second axis, thereby further simplifying the structure of the drive mechanism and reducing testing costs.

[0016] In some possible implementations, the first drive structure includes a first rotating arm with a first axis, and the second drive structure includes a second rotating arm with a second axis. Both the first and second rotating arms are connected to a motor, and the second rotating arm connects the first rotating arm and the swing arm. Thus, by cooperating with the motor and either the first or second rotating arm, the longitude or latitude of the light source can be changed, effectively simplifying the structure of the drive mechanism and reducing testing costs.

[0017] In some possible implementations, the light source is detachably connected to the drive mechanism. This facilitates the replacement of different types of light sources.

[0018] In some possible implementations, the light source includes an adjustable power light source and / or an adjustable color temperature light source. This improves the adaptability to testing scenarios.

[0019] In some possible implementations, the clamp includes a main plate and a clamping plate. The clamping plate, together with the main plate, clamps a terminal equipped with a camera. The clamping plate is movably disposed on the main plate to move the camera to a preset spherical center position. Thus, the main plate and the clamping plate can jointly clamp the terminal, fixing the camera in place. During this process, the clamping position of the terminal can be adjusted by moving the clamping plate, ensuring the camera is at the preset spherical center position.

[0020] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, a three-dimensional coordinate system can be established for the glare testing device, i.e. Figure 1 The XYZ coordinate system is used, where the X direction represents the front-to-back direction, the Y direction represents the left-to-right direction, and the Z direction represents the up-to-down direction. The side indicated by the arrow is considered up, and the opposite side is considered down. "Inner" and "outer" refer to the inner and outer contours of each component. The terms "first," "second," etc., are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be elaborated upon in this disclosure.

[0028] According to some embodiments of this disclosure, a glare testing apparatus is provided, with reference to... Figure 1 and Figure 2 As shown, the glare testing device includes: a base 1; a clamp 2 disposed on the base 1, the clamp 2 being used to hold the camera 10 and drive the camera 10 to a preset sphere center position; a light source 3; and a drive mechanism 4 disposed on the base 1, the drive mechanism 4 being configured to drive the light source 3 to move on a sphere with the preset sphere center as the sphere center, and to cause the light source 3 to emit light toward the preset sphere center.

[0029] Through the above technical solution, in the glare testing device provided in this disclosure, when testing the glare phenomenon of camera 10, camera 10 can first be placed on clamp 2 and fixed by clamp 2. During this process, clamp 2 can be used to move camera 10 so that camera 10 is positioned at a preset sphere center. Subsequently, drive mechanism 4 can drive light source 3 to move. When light source 3 is on a sphere with the preset sphere center as its center, light source 3 emits light towards the preset sphere center, that is, it emits light towards camera 10. Thus, the glare phenomenon of camera 10 can be tested. In particular, since drive mechanism 4 of this disclosure can drive light source 3 to move on a sphere with the preset sphere center as its center, that is, drive mechanism 4 can simultaneously change the longitude and latitude of light source 3, it is suitable for light source 3 to illuminate camera 10 from different positions and / or different incident angles, thereby effectively improving the testing range of glare testing.

[0030] It should be noted that, for a sphere, by defining the longitude and latitude, the coordinates of any point on the sphere can be located. When conducting glare testing, this disclosure can test the test points that need to be tested, that is, these test points are all arranged on the sphere with the preset center as the center.

[0031] In some embodiments, for some cameras 10, such as the camera 10 on the terminal 100, the shooting angle of the camera 10 often corresponds to half of a sphere. In this case, the driving mechanism 4 of this disclosure can drive the light source 3 to move on a half-sphere with a preset center, that is, to move on the hemisphere. Of course, the longitude range of the light source 3 can also be ±180°, and the latitude range can be ±90°, that is, to cover the entire sphere.

[0032] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the driving mechanism 4 may include a first driving structure 41 and a second driving structure 42 connected to each other. The first driving structure 41 is used to drive the light source 3 to rotate around a first axis 20, and the second driving structure 42 is used to drive the light source 3 to rotate around a second axis 30. The first axis 20 and the second axis 30 are perpendicular to each other. Thus, since the first axis 20 and the second axis 30 are perpendicular, the first driving structure 41 can change one of the longitude and latitude of the light source 3, and the second driving structure 42 can change the other of the longitude and latitude of the light source 3. Therefore, the driving mechanism 4 can simultaneously change the longitude and latitude of the light source 3.

[0033] In some embodiments of this disclosure, reference is made to Figure 1As shown, the driving mechanism 4 may further include a third driving structure 43, which is connected to the second driving structure 42 and configured to ensure that the distance between the light source 3 and the preset center of the sphere is equal to the radius of the sphere centered at the preset center. In other words, the third driving structure 43 is used to keep the distance between the light source 3 and the preset center of the sphere equal to, or always equal to, the radius of the sphere. This allows the light source 3 to remain on the sphere, even if all test points of the light source 3 are arranged on the sphere. Thus, through the cooperation of the first driving structure 41, the second driving structure 42, and the third driving structure 43, the light source 3 can move on the sphere centered at the preset center. Of course, during the movement of the light source 3 from one test point to another, the light source 3 can be detached from the sphere.

[0034] In some other embodiments of this disclosure, when the spatial intersection of the first axis 20 and the second axis 30 is the aforementioned preset sphere center, the aforementioned third drive structure 43 can be omitted. That is to say, the setting of the aforementioned third drive structure 43 allows the drive mechanism 4 to be flexibly arranged at any position on the base 1, which effectively simplifies the manufacturing difficulty and structure of the glare testing device.

[0035] In some implementations, reference Figure 1 and Figure 2 As shown, the first axis 20 can be arranged horizontally, so that the first driving structure 41 can be used to change the latitude of the light source 3, wherein, reference Figure 1 As shown, the first drive structure 41 can be spaced apart from the clamp 2, and the direction of the distance between the first drive structure 41 and the clamp 2 can be parallel to the extension direction of the first axis 20. This facilitates the arrangement of the drive mechanism 4 and the clamp 2 respectively. At this time, the third drive structure 43 is used to at least compensate for the distance between the first drive structure 41 and the clamp 2, as well as the initial height difference between the first drive structure 41 and the preset center of the ball.

[0036] In some embodiments, the first axis 20 may extend in the front-back direction, and the first drive structure 41 and the clamp 2 are spaced apart in the front-back direction.

[0037] In some implementations, reference Figure 1 and Figure 2As shown, the first axis 20 and the second axis 30 are spaced apart, and the direction of the spacing between the first axis 20 and the second axis 30 is perpendicular to the first axis 20 and the second axis 30. That is, the second axis 30 is arranged radially on the first axis 20, and the first axis 20 and the second axis 30 do not intersect. This facilitates the connection between the first drive structure 41 and the second drive structure 42, and avoids the second drive structure 42 being directly connected to the drive shaft of the first drive structure 41. In this case, the third drive structure 43 is at least used to compensate for the gap between the first axis 20 and the second axis 30.

[0038] In some implementations, reference Figure 1 and Figure 2 As shown, the third drive structure 43 may include at least two sequentially connected swing arms 431. The two swing arms 431 at the ends are respectively connected to the second drive structure 42 and the light source 3. The swing axis of the swing arms 431 is parallel to the second axis 30. Each swing arm 431 is connected to a motor 44, so that each swing arm 431 can rotate along its respective swing axis. Since the swing axis of the swing arms 431 is parallel to the second axis 30, by swinging at least two swing arms 431, on the one hand, the position of the light source 3 in the radial and circumferential directions of the second axis 30 can be adjusted so that the distance between the light source 3 and the preset center of the sphere is equal to the radius of the sphere with the preset center of the sphere as its center; on the other hand, the illumination direction of the light source 3 can be adjusted so that the light source 3 emits light towards the preset center of the sphere. Thus, by setting at least two swing arms 431, the light source 3 can be kept on the sphere and emit light towards the preset center of the sphere. The structure is simple and the cost is low.

[0039] In some embodiments, reference Figure 1 and Figure 2 As shown, the number of swing arms 431 can be at least three sections, including a first swing arm 5, a second swing arm 6, and a third swing arm 7 connected in sequence. The length of the second swing arm 6 is greater than the length of the first swing arm 5, and / or the length of the second swing arm 6 is greater than the length of the third swing arm 7. Thus, by making the second swing arm 6 longer, it can be used more effectively to compensate for the gap between the first drive structure 41 and the clamp 2, and / or to compensate for the gap between the first axis 20 and the second axis 30, thereby further simplifying the structure of the drive mechanism 4 and reducing testing costs.

[0040] In some embodiments, reference Figure 2As shown, the number of swing arms 431 can be at least four sections, including a fourth swing arm 8 connected to the third swing arm 7. The aforementioned light source 3 can be mounted on the fourth swing arm 8. Thus, by swinging the fourth swing arm 8, the illumination direction of the light source 3 can be directly changed. Of course, the number of swing arms 431 can be set to other numbers as needed. For example, the more sections of swing arms 431 there are, the more test points the light source 3 can reach, and the wider the test range.

[0041] In some implementations, reference Figure 1 and Figure 2 As shown, the first drive structure 41 may include a first rotating arm 411 with a first axis 20, and the second drive structure 42 includes a second rotating arm 421 with a second axis 30. Both the first rotating arm 411 and the second rotating arm 421 are connected to a motor 44. The second rotating arm 421 connects the first rotating arm 411 and the swing arm 431. In this way, the rotation of the first rotating arm 411 can realize the rotation of the light source 3 around the first axis 20. Similarly, the rotation of the second rotating arm 421 can realize the rotation of the light source 3 around the second axis 30. Thus, by cooperating with the motor 44 and the first rotating arm 411 or the second rotating arm 421, the longitude or latitude of the light source 3 can be changed, thereby effectively simplifying the structure of the drive mechanism 4 and reducing the testing cost.

[0042] In other embodiments of this disclosure, the drive mechanism 4 may also be configured as a multi-axis robotic arm, and the first drive structure 41, the second drive structure 42 and the third drive structure 43 may each be a robotic arm of the multi-axis robotic arm, which is not limited in this respect.

[0043] In some embodiments, reference Figure 1 and Figure 2 As shown, the first rotating arm 411 can drive the light source 3 to move around a plane perpendicular to the first axis 20, and the second rotating arm 421 can drive the light source 3 to move around a plane perpendicular to the second axis 30. The first swing arm 5, the second swing arm 6, and the third swing arm 7 are mainly used to compensate for the gap between the first driving structure 41 and the clamp 2, and / or to compensate for the gap between the first axis 20 and the second axis 30. The third swing arm 7 and the fourth swing arm 8 are mainly used to adjust the illumination direction of the light source 3. Through the above coordinated operation, the light source 3 can be kept moving on the spherical surface, and the light source 3 can illuminate the camera 10 at different positions on the spherical surface.

[0044] In some embodiments, reference Figure 1 and Figure 2As shown, the motor 44 on the second drive structure 42 is connected to the first rotating arm 411, the motor 44 on the first swing arm 5 is connected to the second rotating arm 421, the motor 44 on the second swing arm 6 is connected to the first swing arm 5, the motor 44 on the third swing arm 7 is connected to the second swing arm 6, and the motor 44 on the fourth swing arm 8 is connected to the third swing arm 7.

[0045] In some embodiments, the light source 3 can be detachably connected to the drive mechanism 4. This facilitates the replacement of different types of light sources 3, such as light sources 3 including LED lights, light sources 3 including laser lights, and light sources 3 including ultraviolet lights. In some embodiments, the light source 3 can be detachably connected to the aforementioned swing arm 431, or the swing arm 431 on which the light source 3 is mounted can be detachably connected to the previous swing arm 431.

[0046] In some implementations, the light source 3 may include an adjustable power light source, which allows for testing of glare phenomena of the camera 10 under different lighting conditions, and / or the light source 3 may include an adjustable color temperature light source, which allows for testing of glare phenomena of the camera 10 under different color temperatures. This improves the adaptability of the testing scenario.

[0047] In some implementations, by driving the drive mechanism 4 and adjusting the power and / or color temperature of the light source 3, the glare phenomenon of the camera 10 in various scenarios can be simulated, such as when the light source 3 is incident at a low angle, when the light source 3 emits strong direct light, strong backlight, weak backlight, etc.

[0048] In some embodiments, the power of the light source 3 can be 5W, and this disclosure does not limit it.

[0049] In some embodiments, the drive mechanism 4 may also include a controller, and the motor 44 may include an encoder that can be electrically connected to the controller. Thus, the drive mechanism 4 can be operated automatically with high testing accuracy.

[0050] In some implementations, reference Figure 1 As shown, the clamp 2 may include a main plate 21 and a clamping plate 22. The clamping plate 22 is used to clamp the terminal 100 with the camera 10 together with the main plate 21. The clamping plate 22 is movably disposed on the main plate 21 to move the camera 10 to a preset spherical center position. In this way, the main plate 21 and the clamping plate 22 can jointly clamp the terminal 100 to fix the camera 10. During this process, the clamping position of the terminal 100 can be adjusted by the movement of the clamping plate 22 so that the camera 10 is at the preset spherical center position.

[0051] In some embodiments, reference Figure 1As shown, the first axis 20 can extend in the front-back direction, and the clamping plate 22 can move relative to the main plate 21 in the front-back direction and / or in the up-down direction. Thus, the up-down position and front-back position of the camera 10 can be adjusted. Of course, the clamping plate 22 can also move relative to the main plate 21 in the left-right direction to adjust the left-right position of the camera 10. This disclosure does not limit this.

[0052] In some embodiments, the terminal 100 with camera 10 described above can be a mobile phone, tablet, computer, vehicle camera 10 terminal 100, wearable device, camera, security camera 10, etc., and this disclosure does not impose too many restrictions on it.

[0053] The following will describe in detail the specific usage process of the glare testing device in conjunction with the above-described specific embodiments. Figure 1 and Figure 2 As shown, firstly, the glare testing device can be placed in a darkroom. Then, the terminal 100 with camera 10 is placed on clamp 2. The clamping plate 22 is moved back and forth and / or up and down to adjust the front-back and vertical positions of camera 10, positioning it at a preset spherical center. Next, the terminal 100 is fixed using clamping plate 22 and main plate 21, thus fixing camera 10. Subsequently, the longitude and latitude of light source 3 are changed by the first driving structure 41 and the second driving structure 42. The swinging of each swing arm 431 in the third driving structure 43 positions light source 3 on a spherical surface with the preset spherical center, causing light source 3 to emit light towards camera 10. The image capture effect of camera 10 is then analyzed to determine and analyze the glare phenomenon at this time. Finally, the movement of light source 3 on the spherical surface is used to test the glare phenomenon at various test points. During this process, the brightness and / or color temperature of light source 3 can be adjusted. Therefore, the glare testing device disclosed herein has a low cost, a wide testing range, and a rich testing environment, enabling testing in all directions, across all color temperatures, and with all brightness levels.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
