The three-dimensional virtual scene can provide users with a visual three-dimensional virtual environment, with various multimedia channels such as sound, video, force feedback equipment, etc., to bring users a completely immersive interactive experience. This paper introduces 3D imaging and virtual reality technology in the film and television industry cloud exhibition, and develops a virtual display platform. First of all, this paper divides the registration into two processes: camera calibration and joint calibration of the camera and laser scanner based on the calibration results. Camera calibration can determine the plane model of the calibration board in the camera coordinate system, and the joint calibration uses the RANSAC algorithm to extract the point cloud of the plane model of the calibration board, and then optimizes the distance between the points in the plane model point cloud and the corresponding plane in the camera coordinate system Find the optimal transformation between the two sets of data, and then calculate the registration relationship between the point cloud and the image. Secondly, this article conducts a demand analysis of the film and television industry cloud exhibition platform based on virtual reality technology, including the business goals set by the platform, platform system analysis, overall design, and system operating environment and configuration requirements. This model provides a feasible solution for the visual interaction of the cloud exhibition design of the film and television industry.

三维虚拟场景可以为用户提供一个可视化的三维虚拟环境，拥有声音、视频、力反馈设备等多种多媒体渠道，给用户带来完全沉浸式的交互体验。本文介绍了影视行业云展中的3D成像和虚拟现实技术，并开发了一个虚拟展示平台。首先，本文根据标定结果将配准分为相机标定和相机与激光扫描仪联合标定两个过程。相机标定可以在相机坐标系中确定标定板的平面模型，联合标定使用RANSAC算法提取标定板平面模型的点云，然后优化平面模型点云中的点与相机坐标系中对应平面的距离，找到两组数据之间的最优变换，然后计算点云与图像的配准关系。其次，本文对基于虚拟现实技术的影视行业云会展平台进行需求分析，包括平台设定的业务目标、平台系统分析、总体设计、系统运行环境和配置要求等。该模型为影视行业云展设计的视觉交互提供了可行的解决方案。
