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 moving object shooting method and apparatus. The method comprises the following steps: in an object moving process, separately projecting a structure light source to the object at a plurality of time points, and shooting a plurality of structure light images of the structure light source modulated by the object; demodulating a phase corresponding to a deformation position pixel in each structure light image, and generating corresponding field depth information according to the phase; determining a moving curve between the object and the camera according to the field depth information of the plurality of structure light images, and predicting the distance and the direction of the object away from the camera at a preset time point according to the moving curve; and adjusting a travel curve of focusing of the object according to the distance and the direction so as to shoot an image at the preset time point. Therefore, fast focusing is achieved, the clear shooting of the moving object is achieved, and the shooting definition 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 ...
