Laser scanning has transformed efficiency for Faithful Registered Surveying in Japan

“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.

Objective: reducing time spent on-site

Takashi Nakata, a land and house surveyor for FRS 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.’”

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。bob综合app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

三维激光扫描的一个主要好处是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.

A laser scanner works completely differently. It 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%

正如最初预期的那样，BLK360在减少现场工作时产生了重大结果。“一个人花了三个小时才能使用BLK360来测量一个站点，这将需要三个小时的时间才能为两个拥有一个车站的人提供三个小时。Nakata解释说，工时数量已减少到三个小时。自3D激光扫描仪被引入以来，男子的时间为30％。

“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.

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 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.”
