Description

[0001] technical field [0002] The invention relates to the field of computer measurement and control technology and instruments, in particular to an intelligent laser three-dimensional information measuring instrument. Background technique [0003] 3D laser scanning technology, also known as real scene replication technology, is a technological revolution in the field of surveying and mapping after GPS technology. It breaks through the traditional single-point measurement method and has the unique advantages of high efficiency and high precision. 3D laser scanning technology can provide 3D point cloud data on the surface of the scanned object, so it can be used to obtain high-precision and high-resolution digital terrain models. [0004] Three-dimensional laser scanning technology is a new technology that has emerged in recent years, and it has attracted more and more attention in the research field in China. It uses the principle of laser ranging, and by recording the 3D...

Problems solved by technology

[0006] 1. Only static objects can be measured in a static state, and dynamic objects cannot be measured on a dynamic platform

Existing total stations or scanners for surveying and mapping can only use a telescope to manually aim at the object for static single-point measurement after the instrument is leveled. Continuous high-speed measurement, so in the process of fine 3D scanning measurement of large objects, manual aiming will consume a huge time cost; and when dynamic objects (such as the aiming of an aircraft flying in the air), manual aiming will lag behind significantly. Moving objects, it is impossible to aim at the object for real-time measurement; if the instrument is placed on a moving ship to measure a moving aircraft, it is also a difficult problem that cannot be achieved for traditional 3D laser scanners or total stations

[0007] 2. Manual on-site operation is required for positioning and orientation of the scanner, and remote control is not possible

Since the existing scanners cannot realize the real-time coordinate positioning and orientation of the scanner itself, it needs manual positioning and orientation through other auxiliary equipment, but in actual work, it is often encountered that due to environmental dangers, it is impossible to send personnel to operate the instrument for a long time , or the situation that it is impossible to measure continuously around the clock, traditional instruments have certain limitations because they cannot be separated from the on-site operation of people
