Problems solved by technology

[0003] In order to solve the problems of inaccurate focus and losing the subject when shooting dynamic images, the present invention provides a device and method for capturing, tracking, and focusing dynamic images. As an image capturer, one as a camera, the image capturer shoots a large-angle image, the operator selects the subject in the captured image, the central controller performs image recognition, controls the camera to zoom in on the subject, and compares and analyzes The ranging information of the rangefinder and the sharpness information of the image are obtained by the camera, and the focuser is controlled to focus accurately. When the subject is moving, the central controller calculates the movement speed and direction, controls the electric gimbal to follow the movement of the subject, and keeps the shooting The image is in the required composition position, and at the same time, the focuser is automatically controlled to track the focus to obtain a clear image

Abstract

The invention relates to a dynamic image capturing, tracking and focusing device and method. two cameras and photographic equipment are adopted and fixed above and below the shooting holder; wherein one camera is used as an image capture device, the other camera is used as a shooting device, the image capture device shoots a large-view-angle image, an operator selects a shooting main body in an image display touch screen, and the central controller controls the shooting device to amplify shooting, analyzes the definition of the obtained shooting main body image and the distance measurement information of the distance measuring instrument, and controls the focusing instrument of the shooting device to accurately focus; When the shooting main body moves, the central controller calculates themovement speed and direction, controls the shooting holder to act, keeps the image of the shooting main body at a required composition position, and automatically controls the focusing instrument totrack and focus at the same time to obtain a clear image; The control instrument can switch images needing to be shot at any time in the shooting process. According to the invention, intelligent capturing and tracking of the motion change of the shooting main body are realized, automatic focusing is realized, focusing is accurate and rapid, the shooting main body cannot be lost, and operation is convenient.

Description

technical field [0001] The present invention relates to the technical field of image shooting, in particular to a dynamic image shooting device and method. Background technique [0002] When shooting dynamic images, it is very difficult to align the focal length and keep the subject in the desired composition position, especially when shooting images of birds, wild animals, sports events, etc. Thin, even an experienced videographer with a follow-focuser will often experience inaccurate focus and loss of the subject, resulting in a lot of wasted images. In the prior art, there have been examples of using a ranging device to realize automatic follow focus, but once the subject is in a moving state, the success rate of follow focus is very low, and the situation of losing the subject often occurs. SUMMARY OF THE INVENTION [0003] In order to solve the problems of inaccurate focal length and missing the subject when shooting dynamic images, the present invention provides a d...
