Problems solved by technology

In this way, it is necessary to set the left and right eye cameras separately during production, which is a waste of production efficiency, and each scene rendering calculation needs to be expanded twice in memory, consuming a lot of unnecessary computing power

Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] The basic principle of the 3D virtual camera is the principle of pinhole imaging. Each pixel of a picture is used to store the image recorded by projecting the three-dimensional world onto the two-dimensional plane according to the principle of pinhole imaging, so that each pixel of the two-dimensional plane has a three-dimensional A position point in space corresponds to one, that is, each pixel corresponds to a unique ray (this is a ray tracing unit, e...

Abstract

The invention relates to the technical field of film and television three-dimensional picture manufacturing, and discloses a virtual three-dimensional software simulation binocular stereo camera. The camera comprises: a left eye camera and a right eye camera, wherein the left eye camera comprises a ray starting point A and a pixel storage area B, and the right eye camera comprises a ray starting point A' and a pixel storage area B '. According to the stereo camera, the left-eye camera and the right-eye camera are arranged; two rays of a ray starting point A and a ray starting point A ' are simultaneously emitted, pictures of a left eye camera and a right eye camera are simultaneously calculated, and the total rendering time for rendering a memory expansion scene in a film and television every time is about 10 to 20 percent, so that the efficiency of using the camera is very cost-effective; the effect of the camera is not different from that of two independent cameras; moreover, the camera avoids the situation that a lot of computing power is wasted due to the fact that a scene needs to be triggered twice and is expanded twice in a memory when two traditional cameras calculate respectively.

Description

technical field [0001] The invention relates to the technical field of making stereoscopic pictures of movies and TV, in particular to virtual three-dimensional software simulating binocular stereoscopic cameras. Background technique [0002] Currently, the cameras used to make real 3D movies in the market are to simulate the position of the eyes of a person and place two left and right cameras at the same time. One camera outputs the picture seen by the left eye, and the other camera outputs the picture seen by the right eye. Then submit the rendering tasks of the left and right eye cameras to the rendering farm (two completely independent rendering tasks), and the rendering farm will analyze the scene after receiving the task (one for each task), and calculate the final output image. In this way, it is necessary to set the left and right eye cameras separately during production, which is a waste of production efficiency, and each scene rendering calculation needs to be exp...
