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.

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.’”

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

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.

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.”
