总是有3s

3 days. 3 laser scanning instruments. 3D model.

The cultural heritage project of capturing the Ottoman-period Bursa Grand Mosque in Turkey certainly came as a three – and then as a six.

建于1396年至1399年之间，清真寺最独特的特征之一是Minbar或讲台。每块都在6,666个互锁的胡桃木木材中与一块金属或指甲进行设计，每块代表古兰经的一段。

The Leica Geosystems UAE Office was tasked with capturing a 3D model of theMinbar以及Burset Project＆Engineering的2,215平方米结构的前置。该项目由MerinosAtatürk国会与文化中心委托，作为博物馆奥斯曼时代部分的展览。

“We have reached a high quality dataset within a short time with the Leica T-Scan and C10 ScanStation combination,”Burset项目与工程设计工程师CihanÖzüisik说。”This was the best fitting solution for our reverse engineering project, which we will definitely use again in the future."

合并一种模型的激光扫描仪

建筑物的一般扫描被捕获Leica C10 ScanStation。C10的完整圆顶和360º的专注区域凭借清真寺的20个圆顶和2个宣礼塔，扫描节省了大量时间，使整个项目能够成为仅在3天内完成。

与另一家六角公司合作亚搏苹果appMinbarwas captured with the Leica T-Scan and tracked with Leica Absolute Tracker AT402 by the Hexagon Manufacturing Intelligence scanning team in Turkey.

“With the supreme precision of the Absolute Tracker, I was able to capture every detail of the intricate woodwork in theMinbar，”said Gökhan Sunar, Hexagon Manufacturing Intelligence application manager - portable systems.“结合C10清真寺内部的详细扫描，我们能够提供如此历史和文化重要的地点的完整3D模型。”

Bringing several point clouds into one

注册了由不同仪器捕获的点云，并在3D Reshaper软件中重叠并建模。

总数据大小和建模准确性：

• Around 1GB for high resolution C10 scans at 2 mm
• 3 GB for T-Scan and Absolute Tracker scans 20 micro-metres

The scan data from T-Scan was given in millimeters scale in order to work in a metrology market, however, the unit of C10 scan data was in metres.

To achieve a registration of the multiple data, T-Scan results were scaled in 3DR software with x1000 factor. The datasets then became the same scale, and the best fit registration function was applied to the data.

This enabled registration of the multiple point clouds in the same coordinate system. As a result, 3D models created by meshing command in 3DR and models reconstructed and edited for better quality.

有了这个1-2-3的解决方案，Bursa Grand Mosque现在可以将几代人保存下来。随着博物馆展出的3D模型，人们可以享受其美丽和文化意义。
