Laser scanning has transformed efficiency for Faithful Registered Surveying in Japan

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

Faithful Registered Surveying(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.

Objective: reducing time spent on-site

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.’”

The business’ customers are mainly real estate companies that handle custom construction as well as construction companies and design offices. Speed and price are important factors for clients, so the more quickly that FRS surveyors can work, the more competitive the business is. It was with this in mind that that company introduced 3D laser scanning. “I felt that it is significant to reduce the time of on-site work reliably,” Explains Nakata.

Nakata在选择BLK360之前先研究了各种激光扫描仪。决定性因素是快速性能和机动性，其他一些产品的重量是BLK360的重量高达四倍。亚搏彩票手机版下载“我喜欢BLK360的非常紧凑的尺寸和高性能。它的垂直方向使其方便在狭窄空间中进行测量。我们认为，轻巧且高度可操纵意味着您可以轻松地将其用于日常使用，这在投资效果方面是一个重要的优势。”

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.

激光扫描仪的工作方式完全不同。它以3D捕获物理对象，产生一组被称为点云的测量点。Nakata解释说：“在能见度较差的地方，例如在高围栏之间爬楼梯，很难用一个总站进行测量，我感到压力。如果您在调查站点的多个位置设置了BLK360并获取点云，则可以使用[参考点]来注册点云，例如，在没有墙壁的侧面可见的实用杆。即使在可见度被阻塞的复杂站点中，也可以通过最少的扫描数量获得测量数据，而无需任何担忧，这在减少现场工作所需的时间方面是一个很大的优势。”

全面的数据集节省时间并防止重新工作

激光扫描仪将整个站点捕获在点云中，因此，如果客户询问您的详细信息，那么与原始摘要相比，您无需在现场返回即可进行更多测量。

“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.

减少工时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.

“In addition to simply reducing the number of man-hours, two people can do other things in parallel, such as one person can go to the government office and request for necessary documents while one person is surveying with BLK360. It is also significant that the number of tasks that can be completed by one person has increased. The degree of freedom of work has increased,” Nakata explains.

通过激光扫描发展业务

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 says, “We have already made a video explaining the points of the point cloud data, and attached 3D images with the boundary points and boundaries highlighted, making it easy for customers and related parties to appreciate. Some customers are considering using it in the design of pre-built houses.” Nakata is also researching combiningUnmanned 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.”
