Problems solved by technology

[0004] However, at present, various depth-of-field acquisitions have different degrees of limitations, such as: too small resolution, poor quality of depth map, environmental influence (feature point matching, lack of texture, insufficient lighting or overexposure), depth continuity unstable

[0033] figure 1 For the flow chart of the steps of the method for obtaining image depth of field of the present invention, refer to figure 1 As shown, the embodiment of the present invention provides a method for acquiring image depth of field, which includes the following steps.

[0034] In step S101, at least one two-dimensional (Two-Dimension, 2D) image is obtained by an image acquisition module. The image acquisition module can be an image processing program or a video camera, and the 2D image can be obtained through the image processing program or the video camera. The 2D image of the present invention can be an existing 2D image, or the 2D image of the present invention can also be acquired in real time 2D image, and the 2D image can be a photo or a video image, which is not limited here. The present invention acquires flat 2D images, and obtains depth data in the 2D images through image processing.

[0035] In step S102, a plurality of physical objects in at least on...

Abstract

The invention discloses an image depth-of-field obtaining method and system, and the method comprises the steps: obtaining at least one two-dimensional (two-dimensional) image through an image obtaining module; identifying a plurality of entity objects in the at least one 2D image through an image judgment module; performing 3D image simulation of a plurality of entity objects in the at least one 2D image through a Three-Dimensional (3D) modeling tool; simulating an image parameter of the received at least one 2D image through a video recorder simulation module; performing a first depth adjustment of the at least one 2D image to obtain at least one depth image; combining the at least one 2D image with the at least one depth image; and performing a second depth adjustment of the at least one 2D image.

Description

technical field [0001] The invention relates to a method for acquiring image data, in particular to an image depth acquisition method and system. Background technique [0002] The development of three-dimensional (Three-dimensional, 3D) images is booming day by day, which not only presents images and colors, but also provides the feeling of three-dimensional space. In related technologies, the generation of 3D images is roughly divided into two categories, one is to use 3D lenses (more than two lenses) to shoot to obtain complete 3D scene information, and the other is to use existing two-dimensional (Two- dimensional, 2D) images into 3D images. [0003] Humans perceive the 3D stereoscopic environment through binocular parallax (Binocular parallax). Since the two eyes of human beings are separated by a certain distance in the horizontal direction, the viewing angles of the two eyes are different when viewing physical objects. Depth information of physical objects is reconst...
