激光扫描已改变了日本忠实注册测量的效率

“With BLK360, there is basically no place that cannot be surveyed,” Takashi Nakata.

忠实的注册测量(FRS) is a land surveying company based in Osaka City, Japan. The company’s work ensures an accurate record of property in the area, and is essential for the smooth running of the property market, validating corporate and individual property rights. The company recently increased the speed and efficiency of its on-site survey work by introducing Leica Geosystems' imaging laser scanner, theLeica BLK360。

目的：减少现场花费的时间

隆醒来时,土地和房子FRS的验船师explains the inspection process. “With land inspection, we conduct surveys of the ground to define the exact border of the property, clarify the land use clarification, and registers to the Legal Affairs Bureau. For the building inspection, we classify the category of the building, define the structure, and survey the floor area space and we also registers the results to the Legal Affairs Bureau. We measure and assess the invisible thing called ‘boundary.’”

企业的客户主要是处理定制建筑以及建筑公司和设计办公室的房地产公司。速度和价格是客户的重要因素，因此FRS测量师可以工作的速度越快，业务越具竞争力。考虑到这一点，该公司引入了3D激光扫描。Nakata解释说：“我觉得可以可靠地减少现场工作的时间很重要。”

Nakata researched various laser scanners before choosing the BLK360. The deciding factors were fast performance and mobility, with some other products considered weighing up to four times more than the BLK360. “I liked the BLK360's extremely compact size and high performance. Its vertical orientation makes it convenient for measuring in tight spaces. We decided that being lightweight and highly manoeuvrable means that you can easily use it for everyday use, which is a significant advantage in terms of investment effect.”

Quickly measure sites with poor visibility

A major benefit of 3D laser scanning is the ability to measure difficult spaces quickly. With traverse surveying using total station, you can only measure between the lines of sight of two or more points. If you need to measure around a corner, or a wall blocked by trees, you need to move the total station to measure more points to build a chain of sight around the barrier.

激光扫描仪的工作原理完全不同。它captures physical objects in 3D, producing a comprehensive set of measurement points known as a point cloud. Nakata explains, “In places with poor visibility, such as climbing stairs between high fences, it is very difficult to measure with a total station, and I feel stress. If you set BLK360 at multiple places in the survey site and acquire point clouds, you can register point clouds by using [a point of reference], for example, a utility pole that is visible on the side without walls. Even in a complex site where the visibility is blocked , the measurement data can be obtained with the minimum number of scans without any worries, which is a great advantage in reducing the time required for on-site work.”

Comprehensive datasets save time and prevent re-work

Laser scanner captures the entire site in a point cloud, so if you are asked by a client for more detail than was in the original brief, you don’t need to go back on-site to take more measurements.

“Before, when I made a cross-section of a position and presented it, I was often suddenly told, ‘I want a cross-section of this position.’ In the past, we had to go to the site again and repeat the measurement each time. Not only revisiting the site but also measuring extra points just in case is an extra and wasteful task, which will increase the on-site work hours. With BLK360, the problem of redoing on-site work has been resolved. Since we have 3D data, we can handle level measurement and cross-sectional views immediately by processing point cloud data stored in office PC if we receive an additional request,” says Nakata.

Reduction of work man-hours by 30%

As initially expected, the BLK360 delivered significant results in reducing fieldwork time. “It took three hours for one person to use the BLK360 to measure a site, which would take three hours for two people with a total station. The number of man-hours has been halved to three man-hours," explains Nakata. Adding in the time taken to process and edit the point cloud and the time for projects, which still require using a total station, has saved the business about 30% in man hours since the 3D laser scanner was introduced.

“除了简单地减少工时的数量外，两个人还可以并行做其他事情，例如一个人可以去政府办公室并要求在一个人与BLK360进行调查的同时请求必要的文件。同样重要的是，一个人可以完成的任务数量有所增加。工作自由度增加了。” Nakata解释说。

Growing the business with laser scanning

Being able to offer 3D laser scanning as a service is helping FRS to differentiate and grow its business. The company is currently educating customers and prospective companies about the advantages and potential uses of laser scanning.

Nakata说：“我们已经制作了一个视频，解释了点云数据的点，并将3D图像附加了带有边界点和边界突出显示的3D图像，从而使客户和相关方易于欣赏。一些客户正在考虑在预建房屋的设计中使用它。”Nakata也正在研究组合Unmanned Aerial Vehicle(UAV) data capture with the BLK360 to expand the range of work that the company can undertake. “With BLK360, there is basically no place that cannot be surveyed.”
