Description

Polarization adjustment method and device for polarization equipment, electronic equipment and readable medium Technical Field Embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method and apparatus for adjusting polarization of a polarization device, an electronic device, and a readable medium. Background With the development of computer technology and optical technology, polarization imaging technology has also advanced greatly. The polarization information generally reflects the surface features, shape, texture, roughness, etc. of the substance itself. Thus, polarization in combination with imaging enables more comprehensive target and background information to be obtained. Currently, in performing an adjustment operation on a polarization apparatus, it is generally adopted to (1) acquire a polarization angle to be rotated by a priori knowledge (e.g., personal experience of an operator) or a randomly set manner, then rotate the polarization apparatus (e.g., a polarizer) to a corresponding polarization angle, and perform image capturing. However, when the above manner is adopted, there are often the following technical problems: the polarization angle is determined by priori knowledge or random setting, so that randomness and uncertainty of the determined polarization angle under different environments are larger, namely, the environment adaptability of the determined optimal polarization angle is poorer, and further acquired image quality is poorer, and object imaging definition and object recognition degree are poorer. Continuing, in the process of carrying out polarization adjustment by adopting the polarization equipment and determining the polarization angle with better imaging effect, the following technical problems further exist: Because different users pursue different shooting targets (such as extinction effect or image contrast ratio), the set measurement indexes are different, and in the process of determining the target polarization angle with better imaging effect based on the set measurement indexes, the conventional determination mode can directly determine that the current polarization angle is the final target polarization angle according to the comparison of the current index corresponding to the current polarization angle and the left index corresponding to the left polarization angle and the right index corresponding to the right polarization angle. The condition that the determined current polarization angle is in the better polarization area with smaller error is easily ignored, so that the accuracy of the determined polarization angle is lower, and further, the object imaging definition and the object recognition degree of a shot image are poorer. The above information disclosed in this background section is only for enhancement of understanding of the background of the inventive concept and, therefore, may contain information that does not form the prior art that is already known to those of ordinary skill in the art in this country.
