terrestrial mapping astronomical theodolite
It builds coordinate and their correlations of photoelectricity theodolite.
Based on the experience from using the theodolite for 20years, we discussed how to use theodolite to observe wind and how to improve the observation quality.
The infrared theodolite plays an important role in shooting range monitoring, and the video image interpretation directly affects the measurement precision of the infrared theodolite.
And the error ranges of the measurements with theodolite and level are evaluated.
Measurement error from the photoelectric theodolite is the main error in the ballistic trajectory measurement.
To solve the problem by using intersection survey method of electronic theodolite is a availability method.
The measuring principle of large curved surface measurement system is intersection measurement of electronic theodolite.
Monitoring contents are verticality and horizontality of support beam, which are monitored by laser plumb instrument and electronic theodolite separately.
Sales of surveying and mapping equipment from conventional optical theodolite, Level electronic Total Station, GPS and software.
Study proves that use of gyroscopic theodolite can decrease the error propagation in the underground traverses survey.
A new method of optimal disposition theory of theodolite was presented to detect the duplicate-aim precision of artillery.
The current metrological verification system for traditional theodolite has disadvantages of large volume, low automation, inconvenient metrological operation and bad measurement repeatability.
Using electron theodolite dummy photograph observing tunnel border displacement, as the example, the authors analyse the principle, means and precision of the system.
A design was presented for wide sped governing scheme of movable glass plate unique to theodolite for fire away trajectory photography.
Principle of the industrial system measurement using a theodolite as the sensor is introduced, with sources of error and their effects upon precision analyzed.
In order to realize the detection accuracy of the system requirements, theline laser was used as the light source, and the 0.5〃 Lycra theodolite and micrometer were applied todetect the assembly.
