事故再现 & 法医测量
iWitnessPRO is extensively used for traffic accident reconstruction and forensic measurement, with photogrammetric technology being equally applicable outdoors or indoors, with photography from the ground or from UAVs (drones). Notable advantages of the iWitnessPRO approach include:
- 快速现场录音领先最少封路 & 少交通中断
- iWitnessPRO is very easy to use & provides fast & accurate 3D measurements
- 业务场景︰ 手动通过半-到全自动
iWitnessPRO has been adopted as standard approach for accident reconstruction across multiple states and 100s of police departments in North America and internationally.
iWitnessPRO is an ideal 3D measurement tools for a wide range of 3D measurement and modelling tasks in architecture, archaeology & heritage recording in general. The recognised attributes of photogrammetry for these applications centre upon the rapid, non-contact nature of the photography; the fact that scenes can be comprehensively recorded with image measurements being possible at any time; and the ease of use of iWitnessPRO-基于测量，不需要更多比消费级相机，以支持业务方案从手动功能测量到全自动 3D 对象重建。这些属性的例子是造型 Holsten Tor 在吕贝克，如下图所示。

芦苇 and iWitnessPRO are applied in engineering for purposes ranging from design and as-built surveys through to deformation measurement where the automatic measurement functions of iWitnessPRO are especially beneficial. Accuracies to around 1:50,000 are attainable via 芦苇' 自动 3D 测量过程时利用目标和质量好单反相机。
iWitnessPRO 用于测量师主要为特征的调查，并经常生成三维坐标数据支持建筑和规划审批过程。由三维特征点的测定 iWitnessPRO in local surveys requiring modest accuracy is often faster than via a total station, especially when point numbers run into the hundreds. It is also suited to the automated generation of 3D surface models and associated rectified and orthorectified imagery, and it is an ideal tool for localised mapping from photography gathered by a UAV (drone), where digital surface models (DSMs) and orthoimagery are generally sought.
