Topcon has filed a patent for a laser scanning method that efficiently manages and controls construction machines at civil engineering sites. The method involves performing a first laser scanning on the blade of a construction machine and a second laser scanning on the area where the machine has operated. The first laser scanning is done at a higher frequency than the second laser scanning. GlobalData’s report on Topcon gives a 360-degree view of the company including its patenting strategy.

Construction machine laser scanning method with different frequencies
A recently filed patent (Publication Number: US20230314133A1) describes a laser scanning method and system for construction machines. The method involves two types of laser scanning performed by a laser scanning apparatus. The first laser scanning is performed on the blade of the construction machine, while the second laser scanning is performed on the area where the machine has operated. Importantly, the first laser scanning is done at a higher frequency than the second laser scanning.
The purpose of the first laser scanning is to control the blade of the construction machine. This suggests that the scanning is used to monitor and adjust the position and movement of the blade during construction operations. On the other hand, the second laser scanning covers at least a part of the construction machine and is likely used to assess the work area and gather data on the machine's operation.
The patent also mentions that the operation can be shifted from the first laser scanning to the second laser scanning based on the position of the blade identified by the first scanning. This indicates that the system has the capability to automatically switch between the two scanning modes depending on the blade's position. Additionally, the operation can be shifted if the distance between the blade's position and the work target exceeds a predetermined value.
The patent further describes a laser scanning system that includes a laser scanning apparatus and a controller. The apparatus is responsible for performing the first and second laser scanning, while the controller ensures that the first scanning is done at a higher frequency than the second scanning. This system is designed to optimize the scanning process and improve the efficiency of construction machine operations.
In conclusion, this patent introduces a laser scanning method and system specifically tailored for construction machines. By utilizing two types of laser scanning at different frequencies, the system aims to enhance the control and monitoring of the machine's blade and assess the work area. The ability to automatically shift between scanning modes based on the blade's position adds a level of automation and efficiency to the process. Overall, this patent presents a novel approach to laser scanning in the construction industry.
