Problems solved by technology
However, the laser rangefinder or ultrasonic rangefinder can only be aimed at the midpoint of the image or fixed at a certain angle. In practical applications, the focus object may be at any position in the image, so continuous focus cannot be achieved or focus is inaccurate.
In the case that it is not suitable for automatic focusing, it can only be manually adjusted. A skilled focuser needs many years of focusing experience. In some cases where the depth of field is relatively shallow and the focus target moves continuously, manual focusing is extremely difficult.
[0004] Therefore, the image focusing of the prior art cannot achieve accurate and fast focusing

The invention provides an image focusing system and method based on wireless ranging, and a shooting system. The image focusing system based on wireless ranging includes a main ranging module, at least one sub ranging module, and an image acquisition device, wherein the main ranging module and the plurality of sub ranging modules are connected in a short-distance wireless communication mode. The technical scheme provided by the invention is provided with functions for automatically controlling a lens to rotate around a focal circle to realize rapid focusing of a camera.
Description
[0001] technical fieldp [0002] The invention relates to the fields of imaging and communication, in particular to an image focusing system, method and shooting system based on wireless ranging. Background technique [0003] With the development of the film and television industry, photographic equipment is becoming more and more advanced and intelligent. In the existing technology, the automatic focusing method of the image can generally be: use a laser rangefinder or an ultrasonic rangefinder to measure the focusing object and the camera The distance of the focal plane, according to which the device that controls the automatic focus of the camera. However, laser rangefinders or ultrasonic rangefinders can only be aimed at the midpoint of the image or fixed at a certain angle. In practical applications, the focus object may be at any position in the image, so continuous focus cannot be achieved or focus is inaccurate. In the case that it is not suitable for automatic focus...
