Abstract

The invention relates to a method for calculating the three-dimensional depth of field based on double imaging device. The method comprises the steps of acquiring a first image and a second image, which are respectively collected by a first imaging device and a second imaging device, of a target object; determining a first pixel point in the first image, and acquiring a first row sequence value and a first column sequence value of the first pixel point; acquiring a second pixel point set in the second image; determining a pixel point with the highest similarity reference value in the second pixel point set to serve as a target pixel point; calculating the pixel position difference between the first pixel point and the target pixel point; and calculating a three-dimensional depth of field value of a point corresponding to the first pixel point and the target pixel point in the target object according to the pixel position difference. The beneficial effects lie in that the three-dimensional depth of field value of a certain point in the target object can be quickly determined according to the method for calculating the three-dimensional depth of field based on the double imaging device.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional imaging, and in particular relates to a calculation method and system for a three-dimensional depth of field based on dual imaging devices. Background technique [0002] When people look at things with both eyes, they can perceive things to have visual depth. With the continuous development of technology in the field of vision, three-dimensional stereo vision has been applied to various fields such as film and television, entertainment and so on. However, in the prior art, a large workload is involved in the process of realizing binocular depth of field calculation, which makes it difficult to achieve real-time performance and meet the requirements of fast-response video analysis. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a method for calculating a three-dimensional depth of field based on dual imaging devices, the method ...
