Abstract

The invention discloses a focal length adjusting method, device and equipment and a storage medium, and relates to the field of cloud computing, deep learning and optical design. The specific implementation scheme is as follows: performing quality evaluation on an image acquired by an image acquisition device to obtain a quality evaluation result; acquiring at least two preset focal lengths in response to determining that the quality evaluation result is less than a preset quality threshold; determining a target focal length of the image acquisition device based on the at least two preset focal lengths, the quality evaluation results of the images acquired based on the at least two preset focal lengths and preset conditions; and adjusting the image acquisition device according to the target focal length. According to the implementation mode, the focal length of the optical system can be automatically adjusted in time, and the quality of images collected by the optical system is improved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the fields of cloud computing, deep learning, and optical design, and in particular to methods, devices, equipment, and storage media for adjusting focus. Background technique [0002] With the application of optical systems in the field of imaging, images have become an important and indispensable information carrier. At present, the imaging technology of the optical system has been widely used, including various aspects such as agriculture, industry, military affairs, and medicine. From mobile phones, digital cameras, microscopes, video cameras, monitoring equipment, to theodolites and space telescopes, which are indispensable in daily life, imaging technology of optical systems is required. [0003] The retina of the human eye has the function of changing the light energy to ensure clear viewing of objects at different distances. The optical lens can be similar to...
