Embodiment Construction

[0040] In order to overcome the deficiencies of the prior art, the present invention aims to propose a new restoration method of the ground-based cloud image, which can better repair the image of the ground-based cloud image and expand the effective area of ​​the cloud image. The TSI equipment is used to collect the ground-based cloud image, combined with the geographical location information, the positions of the shading belt and the lens arm in the cloud image are automatically marked, that is, the area to be repaired is determined, and then the improved Criminisi algorithm is used to repair the ground-based cloud image. The flow chart of technical scheme of the present invention is as figure 1 As shown, it mainly includes the following:

[0041] 1. Location extraction of the area to be repaired

[0042] 1) Determine the shooting time of the TSI cloud image and the latitude and longitude of the location of the device;

[0043] 2) Calculate the solar declination angle δ;

Abstract

The invention relates to the technical field of digital image processing, and provides a new foundation cloud picture restoration method which can better restore an image of a foundation cloud picture, expand an effective area of the cloud picture and automatically mark the positions of a shading belt and a lens arm in the cloud picture, namely, determine a to-be-restored area and restore the foundation cloud picture. According to the technical scheme, the foundation cloud picture repairing method based on the improved Criminisi algorithm comprises the following steps that 1, the position of ato-be-repaired area is extracted; (1) determining the shooting time of a TSI cloud picture and the longitude and latitude of the position where equipment is located, (2) calculating the solar declination angle Delta, (3) calculating the solar time angle omega, (4) calculating the solar azimuth angle Gamma s and the zenith angle theta z, (5) determining the position of a shading band, (6) determining the position of a lens arm, and (2) repairing the cloud picture.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a method for repairing ground-based cloud images in a photovoltaic system. Background technique [0002] Photovoltaic power generation is an energy conversion system that uses the photovoltaic effect to directly convert solar radiation energy into usable electrical energy. The amount of power output by using photovoltaic power generation is determined by the amount of solar radiation received by the solar photovoltaic panel, so it is closely related to real-time weather conditions, which will lead to instability of output power performance and estimation errors. The output power of photovoltaic power generation is closely related to the ground irradiance. Cloud energy directly affects the ground irradiance. Its generation, demise and movement lead to uncertain changes in output power. Analyzing and discussing how clouds affect ground irradiance has become a key ...
