Adaptive real-time data intersection method of photoelectric theodolite

Abstract

The invention relates to an adaptive real-time data intersection method of a photoelectric theodolite, belongs to the technical field of measurement and control, and aims at ensuring that real-time intersection software can implement correct intersection operation after receiving the proper amount of data. The method mainly comprises that 1 ) data of intersection calculation is received and determined to belong to the same batch; 2) an appropriate calculating function matches the data screened from the present batch; and 3) the data matches parameters of the photoelectric equipment sending thedata. The utilization rate of the angle measurement data of the photoelectric theodolite is improved, difficulty in determining time and data for intersection in real-time interaction is overcome, data intersection of the photoelectric theodolite is implemented smoothly, and the method has high practical value of optical measurement in measurement and control.

Description

technical field

[0001] The invention relates to a photoelectric theodolite in the measurement and control technology, in particular to real-time data intersection calculation of the photoelectric theodolite. Background technique

[0002] The photoelectric theodolite is the main measurement and control equipment today. It is based on the electrification of the optical theodolite to realize the synchronous real-time recording of the image of the measured target, the azimuth angle and the elevation angle at the time of measurement. The photoelectric theodolite is used in the tracking and measurement of stationary and moving targets, and is widely used in aircraft test measurements (such as satellite launches, aircraft tests, etc.). While capturing the target image, it can record accurate angle measurement information in real time, and can obtain the accurate central axis offset of the target through the interpretation and processing of the target image afterwards, so that it ca...

[0034] A detailed explanation and description will be given below in conjunction with the accompanying drawings.

[0035] The invention provides an adaptive photoelectric theodolite data real-time rendezvous method.

[0036]The photoelectric theodolite basically sends data to the rendezvous computer at the same time, and transmits data through the network. Therefore, although the computer receives network data one by one, the time interval between receiving two data in the same batch of data is very short. Using this feature, in the rendezvous program, set a timer with a timing value slightly longer than the above time interval, start the timer immediately every time data is received, and when the timing ends, it is considered that all the data of the current batch has been received. The intersection calculation step can be started. Then the program screens the data for time validity, and calculates according to the corresponding rendezvous function according to the number o...
