The purpose of a multifunctional laser rangefinder system
(1) Distance measurement - Distance measurement is the main function of this instrument, which can directly display horizontal distance or tilt distance.
(2) Azimuth - can directly display the magnetic azimuth or relative azimuth of the measured target.
(3) Tilt angle - can display the tilt angle (vertical angle) or tilt percentage.
(4) Target coordinate program - The function of the target program is to measure the so-called location or stake (layout) function, that is, to plot its coordinates (X) at a known point, Y. Z) Input the instrument and align it with the measurement target to immediately display the coordinates of the measurement position.
(5) Height measurement - using the principle of triangulation (elevation, elevation, and horizontal distance) to measure the height of objects, including tree height, building height, etc.
(6) Measurement function - This instrument has another special function program that can directly enter the measurement function, perform measurement work, automatically store azimuth, distance, tilt angle and other data, and can be input into the computer for calculation and processing through PC software.
(7) Navigation function - With a magnetic compass, it can serve as a navigation function.
The combination of multifunctional laser measuring instrument and GPS
The introduction of multifunctional laser measuring instruments was initially mainly combined with GPS, that is, GPS was used in areas with limited terrain to measure with multifunctional laser measuring instruments.
Specific applications:
1) Abolition and clearance of indiscriminate cultivated land
Using laser measuring instruments and GPS The combination of GIS and its software, combined with portable computers for environmental monitoring, is currently a popular research project in various academic institutions. In forestry, it is used for the prohibition and clearance of abandoned land, but further research and testing are needed due to the terrain limitations that GPS may be limited during use. In addition, digital cameras can also be used to capture and archive violations as evidence of crackdowns.
2) Land rental inventory
The combination of a multifunctional laser measuring instrument and GPS for land rental inventory work not only has fast speed, but also high accuracy. In addition, digital image files can also be pre inputted into a portable computer for on-site inspection and comparison work.
3) External security forest inventory
At present, the security forest inventory outside the area of our bureau is carried out using electronic tablets for inspection and pile placement work. However, due to insufficient triangulation points, the inventory work is often slow. If centimeter level GPS can be used for point layout, then laser measuring instruments can be used for measurement, and the target coordinate program function can be used for pile placement, it should accelerate the inventory work and reduce the post mapping data work.
The multifunctional laser measuring instrument has advantages over traditional compasses such as high accuracy, no recording, no drawing, no pulling of measuring ropes, no cutting of grass, time-saving and labor-saving, as well as computer processing and drawing. After on-site testing and operation, it has exceeded the previous instruments by a lot and is worth promoting
