Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0025] The photographing and device of a moving object in the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] It should be understood that in order to solve the technical problems in the prior art that the camera first judges the position of the object and then focuses after the object is in place, the trajectory of the moving object cannot be quickly tracked, and a clear picture of the moving object cannot be taken, A shooting method that predicts the running beha...

Abstract

The invention discloses a shooting method and device for a moving object, wherein the method includes: projecting a structured light source to the object at multiple time points during the moving process of the object, and shooting a plurality of structured light images modulated by the structured light source through the object ;Demodulate the phase corresponding to the deformed position pixel in each structured light image, and generate the corresponding depth of field information according to the phase; determine the motion curve between the object and the camera according to the depth of field information of multiple structured light images, and predict the arrival preset according to the motion curve The distance and direction of the object from the camera at the time point; adjust the travel curve of the camera focus according to the distance and direction, and then take an image when the preset time point is reached. Thus, fast focusing is realized, clear photographing of moving objects is realized, and the definition of photographing is improved.

Description

technical field [0001] The present invention relates to the technical field of photographing by a terminal device, in particular to a method and device for photographing a moving object. Background technique [0002] In related technologies, for objects with different distances from the lens, after passing through the lens, it is necessary to focus clearly in a fixed position. Traditional cameras adopt a method similar to visual distance measurement to achieve automatic focus. The camera emits an infrared (or Other rays), determine the distance of the subject according to the reflection of the subject, and then adjust the lens combination according to the measured results to achieve automatic focusing. [0003] However, this conventional method of first judging the position of the object and then focusing after the object is in place leads to a time difference between the shooting time and the real-time position of the object. When the object moves fast, it is impossible to ...
