Description

Technical Field

[0001] This utility model relates to the field of multispectral testing, specifically to a multispectral collaborative imaging structure. Background Technology

[0002] In the field of multispectral imaging testing, especially in applications involving the coordinated analysis of ultraviolet (UV), visible (VIS), and infrared (IR) bands (such as material aging research, cultural relic preservation, precision agriculture, and industrial inspection), existing technologies often have significant limitations and are unable to meet the requirements for efficient and accurate multi-band coordinated testing.

[0003] On the one hand, when testing needs to cover multiple bands including ultraviolet, visible, and infrared, multiple different dedicated imaging systems are usually required, making it difficult to simultaneously complete multi-band collaborative imaging tests of ultraviolet-visible-infrared. This not only leads to high equipment purchase and maintenance costs, but more importantly, the switching, alignment, and parameter setting processes between different devices are extremely cumbersome and time-consuming. Operators need to repeatedly operate between different devices, severely fragmenting the testing process and making it difficult to achieve truly synchronous or rapid continuous multi-band collaborative observation, greatly reducing testing efficiency and increasing the risk of positioning errors introduced by equipment switching. Furthermore, existing technologies have serious shortcomings in ensuring the standardization and consistency of imaging tests. For imaging devices: limited by their fixed structure, it is difficult to accurately ensure that the camera lens and the surface of the object under test maintain a strict perpendicular relationship after switching different filters (this is crucial for quantitative analysis of ultraviolet and infrared imaging).

[0004] Currently, the relevant existing technologies include:

[0005] A multispectral imaging device (patent document CN218957001U) discloses a multispectral imaging device that achieves multispectral imaging by improving the camera lens and adding multiple filters; however, due to the limited number of filters, the measurable spectral range is insufficient; the limited filter area affects the exposure and final image quality; the inability to guarantee the standardization and consistency of the imaging, and the large human error, this technical solution cannot effectively complete the simultaneous ultraviolet-visible-infrared multi-band collaborative imaging test.

[0006] Therefore, in response to the problem of difficulty in standardizing imaging due to human error in existing technologies, this invention proposes a multispectral collaborative imaging structure. Utility Model Content

[0031] Detailed Implementation

[0032] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0033] like Figure 1 As shown, this utility model embodiment provides a multispectral collaborative imaging structure, including: a light source device 1, a carrier device 2, and an imaging device 3; the imaging device 3 is a movable imaging device.

[0034] The object-carrying device 2 is disposed within the light source device 1, and the imaging device 3 is disposed on the front side of the external light source device 1. When the light source device 1 is in ultraviolet illumination mode and the imaging device 3 is equipped with an ultraviolet camera, ultraviolet imaging of the object is achieved. When the light source device 1 is in visible light illumination mode and the imaging device 3 is equipped with a visible camera, visible color imaging of the object is achieved. When the light source device 1 is in visible light illumination mode and the imaging device 3 is equipped with an infrared camera, infrared thermal imaging of the object is achieved. This multispectral collaborative imaging structure facilitates simultaneous ultraviolet-visible-infrared multi-band imaging of objects, and the standardized and streamlined device provides a faster and more accurate qualitative spectral testing method.

[0035] Furthermore, the light source device 1 includes: a standard light source color matching light box 101 and a light-shielding cloth 102; the light-shielding cloth 102 is pasted on the front side of the standard light source color matching light box 101, so that ambient light cannot enter the interior of the light box, ensuring that the incident light of the object under test comes entirely from the standard light source, thereby improving the imaging accuracy.

[0036] Furthermore, the standard light source color matching light box 101 should include both ultraviolet (UV) and visible (D65) standard light sources to ensure UV-visible-infrared coordinated imaging during use. Furthermore, the light-shielding cloth 102 is a laboratory-specific radiation-proof full-band light-shielding cloth, with an observation hole 103 opened at a certain height from the bottom of the light box on the cloth; the height of the observation hole varies depending on the viewing platform; for a standard D60(4) standard color matching light box, for a standard 400x250x248mm viewing platform, the observation hole is approximately 250mm from the bottom of the light box. Furthermore, the line connecting the observation hole 103 to the object under test is perpendicular to the viewing platform. Based on this, a color matching standard of 45° light source and 0° observation is achieved during imaging testing, thereby ensuring the standardization of the imaging process.

[0037] Furthermore, the loading device 2 includes a viewing stage and the object to be tested, wherein the viewing stage is a 45° standard viewing stage or a variable angle sample stage. More specifically, the position of the object to be tested remains unchanged during the imaging test, and a 45° standard viewing stage or a variable angle sample stage is used to achieve vertical or tilted observation angle imaging.

[0038] Further, the imaging device 3 includes: an optical plate 301, a loading rail 302, a slider 303, an angle mounting bracket 304, a lifting adjustment rod 305, and an imaging camera 306. The optical plate 301 is located in front of the standard light source color matching lamp box 101. The loading rail 302 is mounted on the threaded hole of the optical plate 301 through a countersunk slot and assembled with the slider 303 to form a sliding component. The imaging camera 306 is fixed to the screw of the lifting adjustment rod 305 through a threaded hole and mounted on the angle mounting bracket 306 through a threaded hole to form an imaging component. The imaging component and the sliding component are connected through a countersunk hole, thereby realizing the horizontal movement and vertical lifting of the imaging camera. Further, the optical plate 301 is of sufficient length (greater than 600mm) to ensure that multiple imaging devices can be used simultaneously without interference. The angle mounting bracket 304 is a 45° mounting bracket to realize the vertical observation of the object under test by the camera. The imaging camera 306 is at least two of ultraviolet, visible, and infrared cameras, which image the object under test respectively.

[0039] More specifically, when using this invention, the object to be tested is fixed on the viewing platform and placed inside the standard light source color matching light box 101, and the light-blocking curtain 102 is lowered. When the standard light source color matching light box 101 turns on the UV light source, the ultraviolet imaging camera 306 is moved to the observation point, and the height of the imaging camera 306 is adjusted to be level with the observation hole using the lifting adjustment rod 305, and the camera is focused to achieve ultraviolet imaging. When the standard light source color matching light box 101 turns on the visible light source, the conventional visible camera is moved to the observation point, and the height of the imaging camera 306 is adjusted to be level with the observation hole, and the camera is focused to achieve visible imaging. When the standard light source color matching light box 101 turns on the visible light source, the infrared imaging camera 306 is moved to the observation point, and the height of the imaging camera 306 is adjusted to be level with the observation hole, and the camera is focused to achieve infrared imaging.

[0040] In addition, in one variation of this invention, the temperature and humidity controller can be placed inside the light box to perform ultraviolet-visible-infrared multi-band imaging tests under different temperatures and humidity levels.

[0041] In summary, this invention provides a multispectral collaborative imaging structure, comprising: a light source device 1, an object carrier device 2, and an imaging device 3; the imaging device 3 is a movable imaging device. It can simultaneously perform ultraviolet-visible-infrared multi-band imaging of objects, and the standardized and streamlined device provides a faster and more accurate qualitative spectral testing method; greatly reducing testing errors caused by human operation.
