With the rapid development of new technologies such as electronic technology and laser technology, laser rangefinders were born in line with the times. A laser rangefinder is an instrument that uses a certain parameter of the modulated laser to measure the distance to the target. It is light in weight, small in size, simple in operation, fast and accurate, and its error is only one fifth to several hundredths of other optical rangefinders.
Laser is a new technology developed in the 1960s. It is a kind of light with pure color, highly concentrated energy and good directionality. The application of laser technology to the rangefinder, the fusion of the two, has achieved a great progress in the rangefinder. The principle of action is simple: the distance is determined by measuring the time between when the laser starts firing and when the laser is reflected off the target. These advantages are concentrated in a laser rangefinder, which makes the market situation very good.
Now, laser rangefinders play a certain role in all walks of life, and are widely used in terrain measurement, battlefield measurement; range measurement of tanks, aircraft, ships and artillery to targets; measurement of clouds, aircraft, missiles and artificial satellites height, etc. As the price of laser rangefinders continues to drop, it is getting closer and closer to our daily lives.
House measurement has always been a work that the housing management department cares about and bothers about, because the house survey area map is the attached drawing on the resident's real estate certificate, which has legal effect, and it is directly related to the economic interests of the people, so the accuracy of house measurement appears especially important. Using a tape measure or a steel tape measure to measure according to the previous method, although it can be measured, there is a large error in the measurement of long-distance measurement, floor height measurement, and measurement of difficult-to-reach places, and there are disadvantages such as high labor intensity and complicated work. In today's rapid development of high-tech, this method obviously does not meet the requirements of fast and high efficiency in today's information society. Fortunately, the laser rangefinder appeared in this era. In the measurement of buildings with complex building structures, medium and high-rise buildings, and long distances, as long as you align and scan lightly, the results will come out, easy to use, and accurate measurement data (1.5 mm accuracy). ), the work efficiency is improved, the survey error is reduced, the area measurement accuracy is guaranteed, and the result is more convincing to the owner.
In addition, the laser rangefinder plays an important role in the traffic police's case handling, which can effectively improve the efficiency and accuracy of traffic accident scene investigation. In the handling of traffic accidents, the measurement of the accident scene by the laser rangefinder is a very important part, which plays a key data support for the determination of the vehicle speed at the time of the accident and the characterization of the accident. After the laser rangefinder accurately measures the results, it can automatically input the on-site measurement data and related information into the portable computer through Bluetooth wireless communication, and borrow the high-speed data calculation and graphics processing functions of the computer to quickly measure and map a standardized and accurate traffic accident scene ratio. Maps and automatically generate on-site investigation records, so that the efficiency of traffic police handling cases has been effectively improved.
In addition, laser rangefinders are also widely used in railway platforms, port terminals, cranes, etc. In recent years, under the premise of continuous advancement of science and technology, all walks of life have put forward higher requirements for the distance and accuracy of laser rangefinders, especially in remote distance measurement At the same time, it also focuses on the research of measurement accuracy and integration of various sensors, reduces errors as much as possible, and provides various measurement functions to improve the comprehensive performance of laser rangefinders, thereby expanding the scope of practical applications.
