Title:
SUN-TRACKING CORRECTION SYSTEM AND METHOD BASED ON CELESTIAL BODY IMAGE
Document Type and Number:
WIPO Patent Application WO/2019/100636
Kind Code:
A1
Abstract:
A sun-tracking correction system (2) and method based on a celestial body image. The sun-tracking correction system (2) based on a celestial body image comprises an image collection module (4), which is used for collecting an image of a celestial body (3) in a view field and then sending the data to a data analysis module (5). The data analysis module (5) analyzes a deviation value between the celestial body image and the center of the image in an image coordinate system, and sends the deviation value to a correction calculation module (6). The correction calculation module (6) decomposes the deviation value to corresponding rotation axes according to a rotation manner of a sun-tracking mirror (1), and obtains the error angle of each rotation axis. A data storage module (7) used for storing a correction result of the sun-tracking mirror (1) and a single-correction-period control command list of the sun-tracking mirror (1). A communication module (8) reads the single-correction-period control command list from the data storage module (7), and sends the single-correction-period control command list to the sun-tracking mirror (1), and controls the image collection module (4) to carry out photographing according to the rotating period of the sun-tracking mirror (1). In the sun-tracking correction system (2) and method based on a celestial body image, the system moves according to a law, takes the celestial body (3) with certain brightness, as a mark object, and can carry out the correction during day and night, thereby improving the correction efficiency while the impact on the power generation efficiency is reduced.
