DETAILED DESCRIPTION
[0043] To make the purposes, features and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.
[0044] The embodiments of the present disclosure will be described in detail below with reference to the drawings.
[0045] In combination with Figure 1 And Figure 2 As shown in the figure, the embodiment of the present disclosure provides an anti-strong light imaging device, which comprises a lens 1, a laser light source 2, an image sensor 3 and a light filter 4; the laser light source 2 is arranged upstream of the lens 1 in the optical path, can emit imaging laser to the external environment, and reflect back to the lens 1; the image sensor 3 is arranged downstream of the lens 1 in the optical path, used for converting the imaging laser collected by the lens 1 into an image electrical signal; the light filter 4 is arranged upstream of the image sensor 3 in the optical path, can filter other light and only make imaging laser and light of the same spectrum irradiate on the image sensor 3; wherein, the image sensor 3 is imaged, and the laser light source 2 emits light at the same time.
[0046] The anti-strong light imaging device provided by the embodiment of the present disclosure can be specifically but not limited to applied to image shooting and collection of welding parts in strong light environment in welding workshop, and the use process is described and explained in detail taking this as an example.
[0047] When the anti-strong light imaging device needs to take an image of the welding part of the workpiece, first, the imaging laser is emitted by the laser light source 2 in the anti-strong light imaging device to the external environment, and the imaging laser can be partially reflected back to the lens 1 by the welding part of the workpiece. At this time, the lens 1 is in an exposure state, and because the imaging laser mixed with the environmental interference light (white bright strong light generated by the welding arc) is reflected back into the lens 1, it will seriously affect the normal imaging of the image sensor 3. Therefore, the anti-strong light imaging device is also provided with a light filtering piece 4 in the optical path, and all other light rays except the imaging laser and the same spectrum light rays can be filtered out by the light filtering piece 4, so that only the imaging laser irradiates the image sensor 3, thereby clearly and accurately imaging the welding part of the workpiece, and the anti-strong light imaging device can be applied in various complex strong light environments.
[0048] In addition, it is worth mentioning that when the anti-strong light imaging device takes an image, the lens 1, the laser light source 2 and the image sensor 3 can work simultaneously and synchronously to ensure that the strong light imaging device can coordinate and efficiently realize accurate imaging of the characteristic component target in a strong light environment.
[0049] In an embodiment, the light filtering piece 4 includes a first light filtering piece 41 and a second light filtering piece 42; the first light filtering piece 41 is arranged between the laser light source 2 and the lens 1; the second light filtering piece 42 is arranged between the lens 1 and the image sensor 3; wherein the first light filtering piece 41 and the second light filtering piece 42 can respectively filter other light rays and only make the imaging laser transmit through.
[0050] Specifically, in combination with Figure 2 In further detail, the light filtering piece 4 is specifically arranged to include the first light filtering piece 41 and the second light filtering piece 42, and the first light filtering piece 41 is arranged along the optical path between the laser light source 2 and the lens 1, and the second light filtering piece 42 is arranged along the optical path between the lens 1 and the image sensor 3. In this way, the first light filtering piece 41 and the second light filtering piece 42 can respectively filter the light rays entering the lens 1 before and after the light rays are emitted from the lens 1 for a total of two times, thereby fully ensuring that only the imaging laser irradiates the image sensor 3, thereby further improving the imaging quality of the image sensor 3.
[0051] The specific arrangement of the light filtering piece 4 has the beneficial effects of simple structure, twice filtering of incident light rays, and further improving the imaging quality of the image sensor 3.

[0054] In an embodiment, the first filter 41 is arranged non-perpendicularly to the optical axis of the lens 1, and the second filter 42 is arranged parallel to the image sensor 3 and non-perpendicularly to the optical axis of the lens 1.

[0056] In an embodiment, the angle between the first filter 41 and the optical axis of the lens 1 is 10°-40°, and the angle between the second filter 42 and the optical axis of the lens 1 is 10°-40°.
[0057] Specifically, in combination with the above Figure 2 Further details, the angle between the first filter 41 and the optical axis of the lens 1 is limited to between 10° and 40°, which can be specifically but not limited to 25°, 30°, 35°, etc., and the angle between the second filter 42 and the optical axis of the lens 1 is limited to between 10° and 40°, which can be specifically but not limited to 25°, 30°, 35°, etc. Based on the principle of off-axis imaging light path, a larger depth of field effect can be achieved while the size of the first filter 41, the lens 1, the second filter 42, and the image sensor 3 along the light path direction is more compact.
