Abstract

The invention discloses a manual focusing auxiliary method, an imaging device and an automobile. The method includes: acquiring in real time the image captured by the lens during the process of manually adjusting the focal length of the lens; performing a focusing calculation on the image captured by the lens; judging and prompting the focusing effect of the lens in real time according to the result of the focusing calculation . The method provided by the invention provides users with a unified quantitative standard to measure the effect of manual focusing, and can effectively assist users to complete manual focusing.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an auxiliary method for manual focusing, an imaging device and an automobile. Background technique [0002] With the development of intelligent industry, robot obstacle avoidance, simultaneous localization and mapping technology (SLAM, Simultaneous Localization And Mapping) and unmanned driving technology, cameras are widely used in these fields. In order to obtain a clear image, it is often necessary to adjust the focal length of the camera to optimize the focus value of the camera. At present, the common focusing algorithms are the contrast method (also called the contrast method) and the phase method. Because the phase method focusing requires a certain amount of support from the camera in terms of physical structure, and the requirements for light are relatively high, it is not very common. [0003] For a camera that uses the contrast method to focus, when the came...
