Abstract

The invention provides an automatic astronomical measurement method and system based on video measurement. The measurement method comprises the following steps: importing a contour catalog, acquiringthe number of a target star in the contour catalog, and predicting the area where the target star is located at the current observation time; observing the area where the target star is located at thecurrent observation time, acquiring imaging information, obtaining a star map according to the imaging information, and performing threshold segmentation and star centroid calculation on the star map; converting the star map from pixel coordinates to dial direction coordinates; acquiring azimuth information of a dial, and calculating the target azimuth of the target star by combining with the observation epoch. According to the technical scheme, human eyes are not required for aiming observation, so that detection results are free of personal and instrumental equation and are more accurate; the video device is adjusted according to the area where the target star is located, the detection field of vision can be expanded and the detection blind area can be reduced.

Description

technical field [0001] The invention belongs to the technical field of astronomical measurement, and in particular relates to an automatic astronomical measurement method and measurement system based on video measurement. Background technique [0002] Whether it is in the starting point of the geodetic network, the data measurement of the edge or in the field of national defense construction technology, astronomical measurement plays an irreplaceable role. At present, there are two main methods of astronomical measurement and positioning: [0003] The first measurement method is the astronomical measurement based on the total station mode. This measurement method is to track and aim at the star to be measured by human eyes to record the dial value of the instrument, and to further solve the astronomical latitude and longitude and astronomical positioning; For example, the operation flow of this measurement method is as follows figure 1 As shown; the advantage of this measu...
