Description

Technical Field

[0001] The present invention relates to the technical field of spectral imaging, and in particular to a camera and method for fusing ultraviolet polarization and visible spectrum information. Background Art

[0002] Spectral imaging technology is to record the reflected light brightness distribution or fluorescence brightness distribution of multiple narrow-band monochromatic lights densely and evenly distributed within a certain spectral range of the measured object through an imaging spectrometer, forming a spectral image set composed of many monochromatic light images. Spectral imaging technology is a combination of the development of spectral analysis technology and image analysis technology. Spectral imaging technology can perform qualitative, quantitative and positioning analysis on the measured object because of its dual advantages of image and spectral fingerprint recognition. Since the current spectroscopic devices and detectors cannot cover the entire optical spectrum range, spectral imaging technology can be subdivided into ultraviolet spectral imaging technology, visible spectral imaging technology and infrared spectral imaging technology according to the spectral range. Spectral imaging technologies in different spectral bands have their own characteristics and advantages. Taking the search and identification of physical evidence as an example, ultraviolet spectral imaging technology is mainly used for fingerprint enhancement and fixation. The most significant advantage of visible spectral imaging is that it can distinguish substances with the same color but different spectra, and can eliminate the interference of complex background on the observation of fingerprint and imprint morphology; in addition, the fluorescence wavelengths of many substances are also in the visible spectrum, and visible spectral imaging can distinguish different fluorescent substances by subdividing the wavelengths. Infrared spectral imaging technology can obtain information on molecular vibration or rotation, thereby obtaining more information on material composition and can detect and reveal potential bloodstains and fingerprints, etc.

[0003] Any object will generate polarization information corresponding to its own characteristics due to reflection, scattering, transmission, and radiation of electromagnetic waves. Polarization imaging realizes the fusion of multiple information such as target position, light intensity, and polarization. It can provide surface roughness, texture orientation, surface orientation, surface conductivity, material physical and chemical characteristics, water content, and other characteristics that cannot be displayed by the light intensity image of the target. It has obvious advantages in identifying the contour and surface orientation of objects. For example, transparent plastic and oil film on the water surface that are difficult to show with ordinary imaging can be more clearly displayed in polarization imaging because their surface texture orientation and conductivity are different from those of the background water surface.

[0004] At present, some studies have begun to combine spectral imaging and polarization imaging. Foreign institutions that conduct research on polarization-spectral integrated imaging technology are mainly concentrated in the military and some universities in the United States, Japan, and the European Union. The research focuses mainly on principle exploration, experimental verification, and application evaluation. China is still in the theoretical and preliminary experimental research stage. The more typical polarization-spectral integrated imaging technology is mainly developed on the basis of spectral imagers. For example, liquid crystal tunable filters and acousto-optic tunable filters have polarization characteristics themselves. Spectral imaging equipment based on these filter devices can simply achieve the simultaneous collection of target polarization and spectral characteristics by rotating the angle of the filter device.

[0005] The existing integrated polarization and spectral imaging technologies mainly target the same spectral band, while there are few reports on simultaneous polarization and spectral imaging technologies for different spectral bands. Summary of the invention

[0006] The purpose of the present invention is to provide a camera that fuses ultraviolet polarization and visible spectrum information to solve the problem that the existing polarization and spectrum integrated imaging technology can only be applied to the same spectral band, while having the advantage of a large overlap rate between polarization images and spectrum images.

[0007] In addition, the present invention also provides a fusion method of the above-mentioned ultraviolet polarization and visible spectrum information fusion camera.

[0008] The present invention is achieved through the following technical solutions:

[0009] A camera for fusion of ultraviolet polarization and visible spectrum information, comprising a visible spectrum imaging subsystem, an ultraviolet polarization imaging optical subsystem and a control storage unit:

[0010] The visible spectrum imaging subsystem includes a visible lens, a filter and a visible camera, and is used to receive the reflected visible light generated by the light source irradiating the target and the background, and the visible fluorescence emitted by the target and the background, and form a spectrum image;

[0011] The ultraviolet polarization imaging optical subsystem comprises an ultraviolet lens, a polarizer and an ultraviolet camera, and is used to receive reflected ultraviolet rays generated by the light source irradiating the target and the background and form a polarized image;

[0012] The control storage unit is used for receiving, storing, calculating overlap ratio and fusing spectral images and polarization images. The control storage unit also includes a slide bar with a cursor. The value range of the slide bar increases linearly from 0% to 100%. The position of the cursor is associated with the overlap ratio C.

[0013] The visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem are closely arranged in parallel.

[0014] The visible lens, filter, visible camera, external lens, polarizer and ultraviolet camera described in the present invention are all prior art; the control storage unit adopts technology.

[0015] The present invention is different from the existing polarization-spectrum integrated imaging technology that simply achieves the simultaneous collection of target polarization and spectral characteristics by rotating the angle of the filter device. The visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem described in the present application are two independent subsystems. The spectral image and the polarization image are separately obtained by the visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem, which solves the problem that the existing polarization-spectrum integrated imaging technology can only be applied to the same spectral band. In addition, the visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem are closely arranged in parallel, so that the spectral image and the polarization image can achieve the overlap of the image of the same object in the overlapping area only by translation in the horizontal or vertical direction, while ensuring that the spectral image and the polarization image have a large overlap rate.

[0016] At the same time, the visible spectrum imaging subsystem and ultraviolet polarization imaging optical subsystem of the present invention have simple structures and are easy to operate.

[0017] In summary, the present invention solves the problem that the existing polarization-spectrum integrated imaging technology can only be applied to the same spectral band by setting up two independent and parallel visible spectrum imaging subsystems and ultraviolet polarization imaging, which are used to obtain spectral images and polarization images respectively. The parallel and close arrangement ensures that the spectral image and the polarization image have a large overlap rate, and ensures that the spectral image and the polarization image can achieve the coincidence of the same target object through a simple translation operation.

[0018] Furthermore, the visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem have the same field of view, magnification and image resolution.

[0019] Furthermore, the visible lens and the ultraviolet lens have the same focal length, the filter and the polarizer have the same resolution, and the pixel size is also the same.

[0020] That is, the visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem can achieve the same field of view, magnification and image resolution of the images taken by the two through reasonable selection and matching of component parameters.

[0021] Further, the control storage unit includes a processor, a first buffer, a second buffer, a first memory and a second memory;

[0022] The first memory is used to store spectral images and polarization images;

[0023] The first buffer and the second buffer are used to store the spectral image and the polarization image respectively;

[0024] The processor is used to call the spectral image and polarization image stored in the first buffer and the second buffer and perform fusion processing;

[0025] The second memory is used to store the spectral image and the polarization image processed by the processor.

[0026] The processor, the first buffer, the second buffer, the first memory and the second memory described in the present invention are all existing hardware. The purpose of the present invention is to reasonably arrange the processor, the first buffer, the second buffer, the first memory and the second memory, so as to not only realize the basic functions of controlling the reception, storage and fusion of the storage unit, but also to set the first memory to store spectral images and polarization images as archives of original data; by setting two buffers (the first buffer and the second buffer), the visible camera and the ultraviolet camera can use one buffer separately (that is, the visible camera stores the spectral image within a shooting cycle in the first buffer, and the ultraviolet camera stores the polarization image within a shooting cycle in the second buffer) so that the processor can call it, thereby avoiding the problem of reduced operating efficiency caused by the processor directly calling data from the first memory.

[0027] The processor of the present invention processes the data in the first buffer and the second buffer in parallel to obtain visible spectrum processing results and ultraviolet polarization processing results respectively. These processing results are given in the form of pictures, such as spectrum matching diagrams, polarization degree diagrams, etc.

[0028] In summary, the present invention sets up an independent first buffer, a second buffer and a first memory, wherein the first memory is used to store spectral images and polarization images as an archive of original data, the first buffer and the second buffer are used to store spectral images and polarization images respectively, and the processor directly calls the data of the first buffer and the second buffer, thereby improving processing efficiency.

[0029] Furthermore, the control storage unit also includes a display unit, and the display unit is used to display the fusion processing result of the processor.

[0030] Furthermore, the processor adopts a multi-core processor or multiple processors are used in combination.

[0031] Furthermore, the parallel manner is vertically parallel or horizontally parallel.

[0032] Furthermore, the light source is ultraviolet light or visible light or a combination of the two.

[0033] According to the combination of lighting sources and the settings of each imaging subsystem and information fusion method, the camera can be used for various purposes as shown in Table 1. Although working mode 3 using combined lighting has the functions of working modes 1 and 2, the signal-to-noise ratio will be lower than that of working modes 1 and 2 due to the interference of lighting light on the target signal. In actual use, it can be considered as appropriate according to the on-site conditions.

[0035]

[0037] S1: The polarization image and spectral image taken by the UV camera and the visible camera are continuously written into the storage unit in the control storage unit;

[0038] S2: Control the processing unit in the storage unit to call the data of the storage unit and process it, and obtain the visible spectrum processing results and the ultraviolet polarization processing results respectively, and these processing results are given in the form of pictures;

[0044] S31: Automatically calculate the overlap area using the existing algorithm. After the calculation is successful, assign a value to the overlap rate according to the calculation formula of the overlap rate C and display it on the slide bar. If the automatic calculation fails, manually adjust the slide bar to visually adjust the image overlap rate to a suitable position. If the overlap rate given after the automatic calculation is completed is not locked, adjust it by manually adjusting the slide bar to finally reach the correct state. The calculation formula of the overlap rate C is:

[0045]

[0046] Wherein, X is the image resolution value in the overlap adjustment direction, a is the coordinate value of the same object in the first subsystem image in the overlap adjustment direction, and r is the coordinate value of the same object in the second subsystem image in the overlap adjustment direction.

[0048] 1. The present invention sets two independent and parallel visible spectrum imaging subsystems and ultraviolet polarization imaging, which are used to obtain spectral images and polarization images respectively, thereby solving the problem that the existing polarization spectrum integrated imaging technology can only be applied to the same spectral band. The parallel and close arrangement ensures that the spectral image and the polarization image have a large overlap rate, and ensures that the spectral image and the polarization image can achieve the coincidence of the same target object through a simple translation operation.

The present invention sets up an independent first buffer, a second buffer and a first memory, wherein the first memory is used to store spectral images and polarization images as archives of original data, the first buffer and the second buffer are used to store spectral images and polarization images respectively, and the processor directly calls the data of the first buffer and the second buffer, thereby improving processing efficiency, and the first buffer and the second buffer are independent of the first buffer and the second buffer, thereby avoiding frequent data read and write calls.

[0050] 3. The present invention calculates and adjusts the overlapping area of ​​the processing results of the visible spectrum imaging subsystem and the ultraviolet polarization imaging optical subsystem, and can merge the overlap rate adjustment display window and the information fusion display window, simplify the software interface, and improve the software operation efficiency.
