Optical azimuth measuring distance target
The Principle and Structure of Optical Azimuth
Optical azimuth instrument is an instrument that uses optical principles to measure the azimuth and distance of a target. It is mainly composed of telescope, angle meter, distance meter and other parts. The telescope is used to capture the image of the target object, the goniometer is used to measure the angle of the image in the field of view, and the distance meter calculates the distance between the target object and the observer by means of triangulation.
Ranging Method of 2. Optical Azimuth
There are two main ranging methods for optical orientation instruments.
1. Triangulation method: by observing the target object, while measuring the angle on the instrument, and then according to the known object size and angle, the use of trigonometric function to calculate the distance between the target object and the observer
2. Parallax method: Using the principle of human stereoscopic vision, the distance between the target object and the observer is calculated by observing the images of the same target object in different positions.
Advantages and limitations of 3. optical azimuth instrument in practical application Optical azimuth instrument has high accuracy and reliability in practical application, and is widely used in military, geological survey, forest fire prevention and other fields. However, the optical azimuth instrument also has some limitations, such as the weather
And the light has a large influence, the measurement distance is limited, etc.
Development Status and Prospect of Optical Azimuth in China in 4.
The research and manufacture of optical azimuth instrument in China began in the 1950 s and 1960 s. After decades of development, remarkable achievements have been made. At present, the accuracy, stability and automation of optical azimuth instrument in China have been improved, which can meet the application requirements of different fields.
Looking forward to the future, with the continuous progress of science and technology, optical azimuth instrument still has great development potential in the aspects of intelligence, integration, miniaturization and so on.
