3D LUT生成与转换系统的设计与实现

Design and implementation of 3D LUT generating and converting system

在电影工业领域,三维颜色查找表(3D LUT)对于还原正常监看关系、风格化调色起着至关重要的作用。针对传统3D LUT软件功能不均衡、学习使用成本高、智能化程度低等问题,本文基于Python和Qt开发了一款3D LUT生成与转换系统。以标准色彩图(HALD)为核心设计LUT编辑、色彩空间转换、一级校色、第三方软件对接、辅助查看五个功能模块,从智能化处理分析和跨程序数据交换方面拓展了功能。系统功能完善、美观易用、可跨平台,减轻了用户负担,释放调色师的创造力。

In the film industry,3D look up table(3D LUT)plays a crucial role in both restoring monitor calibration and stylising video colour.Aiming at solving common problems for 3D LUT software of unbalanced functions,high learning cost for users and low intelligence,by using Python and Qt,we've developed a 3D LUT generating and conversing system.With the HALD as its core module,a total of five functional modules such as LUT editing,color space conversion,primary color correction,third-party software interface and auxiliary view are designed and developed.It also expands the functions in terms of intelligent processing and cross-program data exchange.The system is fully functional,easy to use and applicable for cross-platform.It also eases the burden on users and releases the creativity of colourists.
