Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The embodiment of the method of heliometry and orientation based on the total station:

[0036] The heliometry and orientation method based on the total station of the present invention can replace human naked eyes to realize automatic observation of the sun and realize automatic measurement; figure 1 As shown, the heliometry method includes the following steps:

[0037] (1) Acquire the sun image; install a filter in front of the total station telescope, and after the sun completely enters the field of view of the telescope, use the laptop computer to control the total station to take pictures of the sun and obtain the sun image; figure 2 An image of the sun taken in the field. Simultaneously record the imaging moment and the horizontal angle and altitude angle of the total station.

[0038] Specifically, taking the Leica TS60 image total station as an examp...

Abstract

The invention relates to a total station and its heliometry and orientation method. Firstly, the solar image is obtained by the total station, and the center of mass of the solar image is extracted by means of edge detection and circle fitting; Transformation model of coordinates and dial coordinates to obtain the observed horizontal angle of the sun; determine the theoretical azimuth of the sun according to the position of the total station, the time of taking photos and the solar ephemeris; calculate the level of the total station according to the theoretical azimuth and the observed horizontal angle of the sun The azimuth in the zero-degree direction of the dial; that is, the present invention utilizes the automatic photographing function of the total station to replace human naked eyes to realize automatic observation of the sun, realize automatic measurement, and improve the efficiency of heliometry and orientation.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a total station and a heliometry and orientation method thereof. Background technique [0002] The observation targets of astronomical measurement are natural celestial bodies such as the sun, moon, planets and stars. Among all natural celestial bodies, the sun is very important, mainly because most of the photoelectric detection equipment on the ground can only observe stars at night, and cannot achieve all-day astronomical measurement. In the optical band, the sun is almost the only natural celestial body that can be used for astronomical measurement during the day, and the sun has sufficient brightness, extremely regular shape, and good imaging quality, so the sun is of great significance for realizing all-time astronomical measurement. [0003] For example, a document published by Zhan Yinhu, Zhang Chao, and Tang Jiaxiang in the 2012 issue of "Survey and...
