Embodiment Construction

[0058] The present invention will be further described below in conjunction with the drawings and embodiments.

[0059] Such as figure 1 As shown, the photorealistic material measurement device based on the camera light source array mode is composed of a light source, a camera, a collection and storage unit, a fixed arm, and a calibration part. They are used for multi-angle lighting, multi-angle shooting, image data recording and processing, and light source cameras. Mobile control and calibration.

[0060] 1. Bracket and support structure: construct a set of camera fixed arm 2 with a radius of 1 meter, a light source rotating arm 1 of 1.25 m to form a shooting bracket, and a central rotating worktable to form a supporting structure. The light source rotating arm 1 and the work surface are connected through the computer serial port Programming control.

[0061] (1) Hemispherical arm: The light source rotating arm 1 and the camera fixed arm 2 adopt hemispherical arms, which are used ...

Abstract

The invention discloses a real sense material measurement device and method based on camera light source array modes. The device comprises a rotating workbench; a material collection platform, a semi-circular camera fixing arm and a rotary semi-circular light source rotating arm are fixed to the rotating workbench; a plurality of cameras are arranged on the camera fixing arm, and a plurality of light sources are arranged on the light source rotating arm. By adopting the extendible camera array and light source array scheme, the collecting efficiency and system cost are controllable; the positions of the cameras are fixed constantly during shooting, and the whole shooting accuracy is guaranteed; the rotating angles of the light source rotating arm and workbench are controllable, and material shooting sampling of different accuracy can be implemented; shooting is performed by adopting different exposure settings, the dynamic range of the final results is extendible, and the material measurement requirements are met; the same high speed recording software SDK is adopted, and a collection card adopted for low-speed collection or special memory CORE adopted for high-speed storage can be compatible.

Description

Technical field [0001] The invention relates to a multi-camera multi-illumination system, and is a real-sensing material measurement device and method based on a camera light source array mode. Background technique [0002] Rendering technology is the main technology of animation film production. The current rendering technology mainly has two development directions, one is the pursuit of real photo-level image quality rendering; the other is the pursuit of special artistic effects non-realistic rendering (Non-Photorealistic Rendering, NPR). Realistic rendering is the effect pursued by most 3D works at present, and the main research points are on authenticity. With the development of technology, photorealistic rendering is increasingly inclined to measure photorealistic materials to improve rendering quality. [0003] Realistic material measurement captures the information of various materials in the real world through the material acquisition system, and stores the information i...
