[0039] The purpose of the camera's angle test is to ensure that the camera can correctly capture the required pictures and perform optimally in specific application scenarios.

[0040] However, when the existing angle test equipment tests the camera, for different lenses, during the test, when different lenses are used for angle testing, due to the shooting distance, the perspective focal length is not clear, resulting in inaccurate test results.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 4 , in an embodiment of the present utility model, the angle test equipment includes:

[0042] The frame 100 has opposite first and second ends 140 and 150. The first end 140 is for mounting the camera 900, and the lens of the camera 900 is oriented towards the second end 150. That is, when the camera is mounted on the frame 100 in the angle testing device, the camera is mounted at the first end 140 of the frame 100, and the lens of the camera is oriented towards the second end 150.

[0043] The first calibration part 200 is provided on the frame 100 and close to the second end 150. Further, the first calibration part 200 being close to the second end 150 in this application can be understood as approaching the second end 150 or abutting on the second end 150 of the frame 100. Specifically, the first calibration part 200 is used to assist in calibrating the camera lens so that the camera lens is located at the test position of the angle testing device.

[0044] The arc scale member 300 is movably provided on the frame 100 and located between the camera and the first calibration part 200, and can move between the camera and the first calibration part 200 to adjust the distance between the arc scale member 300 and the camera. Further, in this embodiment, by the arc scale member 300 being movably provided on the frame 100, during the test for different lenses, the arc scale member 300 can move on the frame 100 according to different lenses, adjust its own distance from the first end 140, that is, the distance from the camera, so that the distance between the lens and the arc scale member 300 conforms to the shooting focal length, making the taken photo clear, and further solving the problem in the prior art that due to the shooting distance, the perspective focal length is not clear, resulting in inaccurate test results. The arc scale member 300 has a central position 330, an arc surface 340, and scale lines 350 formed on the arc surface 340. The arc surface 340 can be configured as a concave arc surface 340. The scale lines 350 are arranged facing the lens of the camera. The first calibration part 200 and the central position 330 are arranged vertically corresponding to each other. Further, the camera adjusts its own position on the first end 140 according to the first calibration part 200 so that the lens structure of the camera corresponds to the central position 330 of the arc scale member 300. After the position of the camera is adjusted, the distance between the arc scale member 300 and the camera is adjusted so that the distance between the camera lens and the arc scale member 300 conforms to the shooting focal length. Then the camera takes a photo. At this time, the camera photo can obtain the scale lines 350 on the arc scale member 300. Further, since the scale lines 350 are formed on the arc surface 340 and arranged facing the lens of the camera, that is, the arc surface 340 of the arc scale member 300 is also arranged facing the camera lens. At this time, the photo obtained by the camera includes the arc surface 340 and the scale lines 350 formed on the arc surface 340. Then the user views the scale of the photo and calculates the horizontal angle, vertical angle, and diagonal angle of the lens through a drawing tool.

[0045] In one embodiment, the angle testing device further includes a first driving mechanism 400 installed on the frame 100. The first driving mechanism 400 is drivingly connected to the arc-shaped scale member 300. In this embodiment, by drivingly connecting the first driving mechanism 400 and the arc-shaped scale member 300, the arc-shaped scale member 300 reciprocates between the camera and the first calibration portion 200, thereby completing the adjustment of the distance between the arc-shaped scale member 300 and the camera. However, this design is not limited thereto. In other embodiments, the arc-shaped scale member 300 can also adjust the distance between itself and the camera manually. Further, when the arc-shaped scale member 300 is adjusted manually, a locking structure such as a bolt can be used to lock the adjusted position of the arc-shaped scale member 300.

[0046] In one embodiment, referring to Figure 4 , the arc-shaped scale member 300 includes a second calibration portion 310 and an extension portion 320 extending outward from the second calibration portion 310. A first through hole 311 is formed in the second calibration portion 310, and the center position 330 is located at the center of the first through hole 311. At this time, the first calibration portion 200 corresponds to the center of the first through hole 311 on the second calibration portion 310. The camera is calibrated by the first calibration portion 200 so that the lens of the camera corresponds to the center of the first through hole 311 of the second calibration portion 310. The arc surface 340 is formed on the extension portion 320, and thus the scale line 350 is also formed on the extension portion 320. At this time, the extending direction of the scale line 350 is set according to the extending direction of the extension portion 320.

[0047] In one embodiment, referring to Figure 1 , Figure 4The angle testing device also includes a mounting bracket 500 movably provided on the frame 100, and the extension portion 320 is configured as a plurality of extension portions 320. Specifically, the plurality of extension portions 320 are evenly distributed in the circumferential direction of the second calibration portion 310, and the plurality of extension portions 320 are each formed with an arcuate surface 340, and at this time, the plurality of arcuate surfaces 340 are each formed with a scale line 350. The plurality of extension portions 320 are connected to the mounting bracket 500, and the first driving mechanism 400 is drivingly connected to the mounting bracket 500. When the first driving mechanism 400 drives the mounting bracket 500 to move on the frame 100, the mounting bracket 500 can drive the plurality of extension portions 320 and the second calibration portion 310 to move, thereby adjusting the distance between the scale line 350 and the camera lens, so that the photos taken by the camera according to different lenses can clearly reflect the scale line 350, thereby facilitating the user to calculate the angle of the camera. Furthermore, in this embodiment, the number of extension portions 320 is configured to be four, and the four extension portions 320 constitute a cross-shaped structure, so that the arc-shaped scale member 300 has a cross-shaped scale line 350, wherein the center of the cross-shaped scale line 350 is the center of the first through hole 311 of the second calibration portion 310, wherein the first through hole 311 of the second calibration portion 310 can be configured as a circular hole.

[0048] In one embodiment, reference Figure 1 、 Figure 4 The frame 100 includes a first mounting plate 110 and a second mounting plate 120 stacked together. The first mounting plate 110 and the second mounting plate 120 are connected by a plurality of connecting rods 130. The first end 140 is located on an end surface of the first mounting plate 110 facing the second mounting plate 120, and the second end 150 is located on an end surface of the second mounting plate 120 facing or away from the first mounting plate 110. When the second end 150 is located on an end surface of the second mounting plate 120 facing away from the first mounting plate 110, a second through hole 121 is defined in the second mounting plate 120. In this manner, the first calibration unit 200 can calibrate the camera position through the second through hole.

[0049] The mounting frame 500 is slidably mounted on the connecting rod 130. Furthermore, when the mounting frame 500 is slidably mounted on one connecting rod 130, the connecting rod 130 is a prismatic structure, and the connecting rod 130 of the prismatic structure has a guiding function. When the mounting frame 500 is slidably mounted on two or more connecting rods 130, the connecting rods 130 can be a prismatic structure or a cylindrical structure. The first driving mechanism 400 drives the mounting frame 500 to reciprocate along the connecting rod 130, so that the mounting frame 500 reciprocates between the first end 140 and the second end 150 of the frame 100. Furthermore, the first driving mechanism 400 can be a linear driving structure such as a driving cylinder assembly or an electric telescopic rod assembly.

[0050] In one embodiment, referring to Figure 2 , the first driving mechanism 400 includes a first rack 410 fixedly arranged on the connecting rod 130, a first driving motor 420 fixedly arranged on the mounting bracket 500, and a first gear 430 arranged at the output end of the first driving motor 420. The first gear 430 meshes with the first rack 410, and the first rack 410 extends along the length direction of the connecting rod 130. In this way, when the first driving mechanism 400 drives the mounting bracket 500 to move, the first driving motor 420 drives the first gear 430 to rotate. Since the first gear 430 meshes with the first rack 410, the first gear 430 can move along the first rack 410 during the rotation process, thereby realizing the movement of the mounting bracket 500 along the first rack 410, and further achieving the purpose of moving the mounting bracket 500 between the first end 140 and the second end 150 of the frame 100. By the forward and reverse rotation of the first driving motor 420, the purpose of reciprocating movement of the mounting bracket 500 between the first end 140 and the second end 150 of the frame 100 is realized. Further, in one embodiment, two sets of the first driving mechanisms 400 are configured, and the two sets of the first driving mechanisms 400 are arranged diagonally (see Figure 2 ). At this time, in this embodiment, four connecting rods 130 are configured and are distributed in a rectangle, and the two sets of the first driving mechanisms 400 are respectively arranged on two diagonal connecting rods 130.

[0051] In one embodiment, referring to Figure 2 、 Figure 3 , the first calibration unit 200 is configured as a laser lamp. The angle testing device further includes a second driving mechanism 600. The second driving mechanism 600 is installed on the frame 100 and is drivingly connected to the first calibration unit 200. The second driving mechanism 600 drives the first calibration unit 200 to make the first calibration unit 200 correspond to the center position 330 of the arc-shaped reflecting member for the purpose of adjusting the first calibration unit 200. Further, in this embodiment, when the first calibration unit 200 is configured as a laser lamp, the laser lamp has a heat source effect. At this time, for a camera with a PIR sensor (infrared sensor), pictures can be taken according to the heat source of the laser lamp.

[0052] In one embodiment, referring to Figure 2 、 Figure 3, the second driving mechanism 600 includes a guide rail 610 installed on the frame 100, a movable box and a plurality of teeth 620 provided on the guide rail 610, a second driving motor 630 installed on the movable box, and a second gear 640 provided at the output end of the second driving motor 630. The second gear 640 meshes with the teeth 620. The laser lamp is installed on the movable box 650, and the movable box 650 is slidably engaged with the guide rail 610. Further, the guide rail 610 has a guiding function. Specifically, a plurality of teeth 620 are arranged along the length direction of the guide rail 610. When the second driving motor 630 operates to drive the second gear 640 to rotate, since the second gear 640 meshes with the teeth 620, at this time, the second gear 640 can move along the length direction of the guide rail 610, thereby driving the movable box 650 to move. When the movable box moves, the laser lamp provided on the movable box can move accordingly, so as to achieve the purpose of adjusting the laser lamp. At the same time, when the second end 150 is provided on one end face of the second mounting plate 120 facing the first mounting plate 110, at this time, the second through hole 121 can be used as an avoidance hole, and the avoidance hole is used to avoid the second driving mechanism 600.

[0053] In one embodiment, referring to Figure 1 , the angle testing device further includes a fixture 700. The fixture 700 is detachably connected to the first end 140, and the fixture 700 is used for placing a camera. Further, in this embodiment, according to different cameras, the corresponding fixture 700 can be replaced. The fixture 700 can be detachably connected to the first end 140 by means of magnetic attraction or screw attachment, that is, the fixture 700 is detachably connected to the first mounting plate 110 of the frame 100. In this way, it is convenient to disassemble and replace the fixture 700 and the frame 100, and the versatility of the angle testing device of the present application is improved.

[0054] In one embodiment, referring to Figure 1 , a light emitting member 800 with adjustable brightness is installed at the first end 140. The light emitting member 800 is located below the camera. The arc scale member 300 is configured as an anti-reflection arc scale member 300. Further, the light emitting member 800 with adjustable brightness is configured as an LED light strip with adjustable brightness. The LED light strips are configured in multiple numbers and are arranged around the camera. Since the light emitting member 800 is located below the camera, the light emitting member 800 can play a backlight role during the shooting process of the camera, thereby improving the clarity of the photos taken by the camera. At the same time, the brightness of the light emitting member 800 in this embodiment can be adjusted, so as to further improve the applicability of the present application.
