Transforming reality into photorealistic Virtual Reality with laser scanning

Author:Reka Vasszi

虽然虚拟现实（VR）通常与视频游戏相关联，但它通过打开各种各样的新可能性来销售产品，体验地点或培训员工来塑造许多行业。bob综合app下载VR具有多个应用程序，基于将用户沉浸在安全的虚拟世界中的能力，并通过涉及大多数感官来充分体验不同的环境。

Reality in Virtual Reality Ltd.（RIVR）是英格兰VR经验的开发商，正在通过为所有行业提供身临其境的培训和教育计划来增强人类学习的方式。基于VR的培训计划可以将用户沉浸在现实情况下，例如犯罪或火灾场景，这些情况无法在现实生活中轻松复制。

The immersive experience RiVR offers is ideal for applications in the public safety sector where VR provides students a way to gain valuable experience of dangerous or life-threatening environments from the safety of a training room. The Fire and Rescue Service and the Department of Science and Technology Laboratory in the United Kingdom both requested RiVR to produce a hyper-realistic recreation of fire and crime scene scenarios based on real-world events to develop virtual training programmes for their trainees. The goal of the training isto prepare students for the appropriate behaviour and actions in stressful situations。一个虚拟现实监视器r (VRM) developed by RiVR allows the trainers to observe how the candidates interact with the scene and gives a comprehensive overview of the training session.

使用徕卡RTC360laser scanner, in combination with photogrammetry, RiVR was able to developlife-like virtual environmentswhere thefire and police officers of the future can be trained。

Virtual firefighters and detectives

该公司凭借其首个产品RIVR调查的开创性，正在补充对消防员，警察和犯罪现场调查员的现实世界培训，具有沉浸式的逼真的VR经验。RIVR调查允许新的新兵以受控且一致的方式获得曝光率。首次将受训者暴露于真正的火灾和危险情况下可能会给工作带来压力和恐惧。VR技术还允许警察和调查人员进行一系列模拟和recreate any murder scene that would not be possible otherwise。

In RiVR Investigate training solution trainees get access to six different fire investigation scenarios, two hazardous material incidents, and two crime scenes. The RiVR software also records all the actions taken by the trainee for review. The team of developers is looking to work with more fire services and police forces to increase the VR scenario library year on year.

但, how are these real-life situations transformed into virtual simulations?RiVR partnered with Leica Geosystems and uses the徕卡RTC360to producehigh-resolution topology of large scenes。The高度便利和自动化RTC360 empowered the team to记录并捕获犯罪现场以及燃烧的建筑物快速，并获得最好的细节。

“当我们扫描不适合摄影测量的大环境时，我们会使用RTC360。然后在扫描上，我们叠加高分辨率图像，以产生任何大小的毫米准确的光真实环境。我们还发现RTC360在很难进行摄影测量扫描的环境中非常有用，例如主要是白色实验室，该实验室没有太多随机性[参考点]，”explained Alex Harvey, creative director at RiVR.

Capturing reality to enhance learning

首次体验新的具有挑战性的环境，例如谋杀现场或火灾，提供了宝贵的背景和locational awareness候选人的情况，否则很难在没有大量费用的情况下复制。具有能力镜子毫米精度the通过激光扫描现实世界，专业人士可以create engaging real-life experiences对于多个应用程序，包括公共安全的情相VR培训。

In a BBC Click episode featuring VR applications, Paul Speight, watch manager at Leicestershire Fire and Rescue Service, states students trained in a VR environment are more engaged. According to a recent report by the National Training Laboratory in the United States, retention rate of learning using VR scored75 per cent。In contrast, other lecture-style methods were at 5 per cent.

通过激光扫描和摄影测量制作的VR可以将用户置于许多不同的地方，情况或环境中，并且可以部署以教授意识，建立技能并为那些冒着生命危险帮助他人的人提供宝贵的经验。
