[0038] Embodiment 1

[0039] Please refer to Figure 1-3 , Embodiment 1 of the present utility model is: an imaging detection device, which can be used to perform imaging detection of cameras with different magnifications.

[0040] like Figure 1 As shown, the imaging channel body 1 includes a light source 2, an adjustable aperture 3, a front cover 4, a first adapter ring 5 and a second adapter ring 6. In this embodiment, the imaging channel body 1 is a hollow cylinder, and in other optional embodiments, it can also be a cuboid. Figure 2 As shown, the two ends of the imaging channel body 1 are respectively a light inlet and a light outlet, the first adapter ring 5 is arranged at the light inlet of the imaging channel body 1, the second adapter ring 6 is arranged at the light outlet of the imaging channel body 1, the front cover 4 is arranged on the side of the first adapter ring 5 away from the imaging channel body 1, the bottom surface of the front cover 4 is provided with a light hole 41, and the light source 2 is located on the side of the front cover 4 away from the first adapter ring 5; the side of the front cover 4 is provided with an opening 42, the adjustable diaphragm 3 is arranged in the front cover 4, and the adjustment rod 31 of the adjustable diaphragm 3 protrudes from the side of the front cover 4 through the opening 42, wherein the adjustment rod 31 is used to adjust the light outlet aperture. In this embodiment, the imaging channel body 1, the light source 2, the adjustable diaphragm 3, the front cover 4, the first adapter ring 5 and the second adapter ring 6 are coaxially arranged.

[0041] like Figure 3 As shown, when imaging detection is to be performed, the camera 7 to be tested is powered on and placed in the position of the second adapter ring 6, and then the light source 2 is turned on, and the light output aperture of the adjustable aperture 3 is synchronously adjusted to form a ratio with the imaging channel body 1 to generate a light source magnification, so that imaging detection of different magnifications can be performed on the camera 7 to be tested, and dirty or bad spots can be detected by analyzing the imaging data of the camera to be tested.

[0042] Among them, the light exit aperture of the adjustable aperture is inversely correlated with the magnification, that is, the smaller the light exit aperture of the adjustable aperture, the greater the magnification of the light source generated; the length of the imaging channel body is positively correlated with the magnification, that is, the shorter the length of the imaging channel body, the smaller the magnification of the light source generated. In this embodiment, the length of the imaging channel body is 250-300mm, and the aperture of the adjustable aperture is 2-25mm. Through the above settings, a magnification of 10-40 times can be achieved.

In an optional embodiment, the diameter of the imaging channel body is 110 mm, and the brightness of the light source is 60 Lux to 39990 Lux.

[0044] At the same time, the brightness of the light source is positively correlated with the magnification.
