Title:
TARGET SKY AREA IMAGE ACQUISITION METHOD AND ASTROPHOTOGRAPHY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/042350
Kind Code:
A1
Abstract:
Disclosed in the present invention are a target sky area image acquisition method and an astrophotography device. The method comprises the following steps: step 1, driving, according to received target right ascension coordinates and target declination coordinates corresponding to a target celestial body, an image acquisition device by means of a controlled rotatable component to direct to a position in the vicinity of a target sky area, and capturing a sky area image by means of the image acquisition device; step 2, analyzing the sky area image to obtain right ascension coordinates and the declination coordinates of the center point of the image, so as to synchronize the right ascension coordinates and the declination coordinates to the controlled rotatable component and determine that the image acquisition device directs to the position where the right ascension coordinates and the declination coordinates are located; step 3, the controlled rotatable component driving, according to the target right ascension coordinates and target declination coordinates as well as the right ascension coordinates and declination coordinates, the image acquisition device to direct to a target position of the target right ascension coordinates and the target declination coordinates corresponding to the target celestial body to allow the image acquisition device to capture a target sky area image; and step 4, performing image processing on the target sky area image to obtain a target sky area image subjected to image processing.
