Background technique

Compared with traditional images, polarization images can better supplement the missing information in traditional images, such as the material and tissue properties, surface roughness, and structural composition of the shooting target. At present, if one wants to obtain polarization images, a common method is to package a polarizer on the photosensitive target surface of the camera to form a pixel polarization camera, so as to obtain polarization images through the pixel polarization camera.

Moiré is a high-frequency interference that causes crosstalk between signals between adjacent pixel units in a polarization camera, resulting in poor imaging quality of the pixel polarization camera.

Therefore, how to control the precise alignment between the pixels of the camera and the polarization units in the polarizer array is an urgent problem to be solved by those skilled in the art.

Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples.

Optical components are used in various optical instruments and systems, and played an indispensable role in various fields of the Republic of China economy. Traditional optical elements are based on the refraction, reflection or diffraction of light, and the changes of the amplitude, phase and polarization state of the incident light are gradually accumulated along the optical path direction. However, among the many characteristic quantities of light that can be used as information carriers, only the amplitude and wavelength, and the information carried by the phase and polarization state are missing in conventional imaging due to the limitation of the physiological structure of the human eyeball.

Polarization cameras, compared to traditional commercial cameras, can better complement the missing information in conventional imaging such as material and tissue properties, surface roughness, structural composition, and three-dimensional shape. At present, a commercial charge coupled device (Charge coupled device, CCD), or complementary metal oxide semiconductor (complementary metal oxide semiconductor, CMOS) camera sensor to obtain polarization images, a commonly used method is time-splitting polarization imaging, that is, rotating the The polarizer in front of the camera, although this method is relatively simple in terms of system design and data simplification, but the process takes a long time and will cause projection errors of the scene on the camera. Another commonly used method is the focal plane spectroscopic polarization imaging measurement, called a pixel polarization camera, which aligns the polarization subunits in the polarizer array one by one on the pixels of the camera. This kind of pixel polarization camera has a simple volume structure, small field angle error, and can measure dynamic targets with less time-consuming.

For the pixel polarization camera, a technical problem in the manufacturing process is: how to realize the precise alignment of the pixels of the camera and the polarization subunits in the polarizer array. Moiré occurs when the camera's pixels are not precisely aligned with the polarizing subunits in the polarizer array. Moiré is a kind of high-frequency interference, which will cause crosstalk between the signals between adjacent pixel units in the polarization camera, resulting in poor imaging quality of the pixel polarization camera, which cannot clearly reflect the details of the image.

Therefore, in the process of packaging the pixel polarization camera, to avoid moiré, it is necessary to better control the precise alignment of the camera pixels and the polarization unit in the polarizer array. In order to better control the camera pixels and the polarizer array The polarizing unit in the camera is precisely aligned, thereby improving the alignment accuracy.

Wherein, the value of the first brightness threshold and the value of the second brightness threshold can be set according to actual needs. Here, for the value of the first brightness threshold and the value of the second brightness threshold, the embodiment of the present invention does not Specific restrictions.

For example, in the embodiment of the present invention, when adjusting the rotation angle of the camera 160, the rotation angle of the camera 160 can be adjusted from the three directions of X, Y, and Z directions, which can be set according to actual needs. Here, this The embodiments of the invention are not specifically limited.

Exemplarily, the controller 110 controls the second displacement automatic control platform 140 to adjust and continue to adjust the horizontal position of the camera 160 based on the gradually enlarged real-time display image of the camera 160.

Wherein, the electronic device is used for receiving the real-time display image of the camera 160 and displaying the gradually enlarged real-time display image of the camera 160 .

The controller 110 is specifically configured to control the second automatic displacement control platform 140 to continue adjusting the horizontal position of the camera 160 based on the gradually enlarged real-time display image displayed by the electronic device.

The controller 110 is specifically configured to determine the brightness corresponding to each of the multiple images and the extinction ratio corresponding to the adjusted camera 160 based on the multiple images collected by the adjusted camera 160 at different angles; The brightness and the adjusted extinction ratio of the camera 160 determine whether to control the second automatic displacement control platform 140 to repeatedly execute the above S1-S3 to adjust the rotation angle and horizontal position of the camera 160 .

For example, the controller 110 may be a controller 110 set independently of the electronic device, or may be a controller 110 in the electronic device, which may be set according to actual needs, which is not specifically limited in this embodiment of the present invention.

Exemplarily, when the controller 110 respectively determines the brightness corresponding to each of the multiple images and the extinction ratio corresponding to the adjusted camera 160 based on the multiple images collected by the adjusted camera 160 at different angles, for example, the polarizer array 150 and The alignment system of the camera 160 also includes a motorized rotating polarizer 170 disposed above the built-in orbital rotating holder 130 .

The camera 160 is also used to collect multiple images at different angles when the electrically rotatable polarizer 170 is rotated to different angles.

The controller 110 is specifically configured to determine the brightness corresponding to each of the multiple images and the extinction ratio corresponding to the adjusted camera 160 based on the multiple images collected by the adjusted camera 160 at different angles; Brightness, judging whether there is a preset number of images whose corresponding brightness is greater than the third brightness threshold, and the brightness difference between the preset images is smaller than the fourth brightness threshold, and judging whether the adjusted extinction ratio of the camera 160 is greater than or equal to the extinction ratio threshold.

The controller 110, specifically, when determining that there is a preset number of images whose corresponding brightness is greater than the third brightness threshold, and the brightness difference between the preset images is smaller than the fourth brightness threshold, and the extinction ratio is greater than or equal to the extinction ratio threshold.
