Embodiment Construction
[0021] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Such as Figure 1-6 As shown, the present invention provides a photovoltaic module positioning method, comprising the following steps:
[0023] S1. Carry out color space conversion on the station panorama bitmap, and convert RGB to HVS color space; the panorama bitmap of the station Figure 1 It is generally obtained by stitching aerial images.
[0024] S2. Perform threshold binarization processing on the generated HSV image, the string area is the foreground color, and the ground is the background color; the foreground color and the background color are different in color;
[0025] S3. Perform filtering processing on the obtained image;
[0026] S4. Extracting the contours of all string regions;
[0027] S5. Obtain pixel coordinate information of all string vertices in the panorama bitmap according to the outline; ...

The invention provides a photovoltaic module positioning method and a detection method, and belongs to the field of photovoltaic module positioning detection. The positioning method comprises the steps: carrying out color space conversion of a panoramic bitmap of a station, and converting RGB into an HVS color space; carrying out threshold binarization processing on a generated HSV image, defininga string area to be a foreground color, and the ground to be a background color, wherein the foreground color is different from the background color; performing filtering processing on the obtained image; extracting contours of all the string area; obtaining vertex pixel coordinate information of all strings in the panoramic bitmap according to the contour; assigning and obtaining longitude and latitude information of at least two points, and calculating longitude and latitude information of vertexes of all the strings; and calculating the vertex longitude and latitude of the component through string vertex longitude and latitude information. According to the invention, problems of a large workload, high cost and error proneness caused by manual dotting of the photovoltaic module in the prior art are solved.
Description
technical field [0001] The invention relates to the field of photovoltaic component positioning detection, in particular to a photovoltaic component positioning method. Background technique [0002] During the production and operation of photovoltaic power plants, in order to improve power generation efficiency, it is necessary to carry out daily inspections of photovoltaic panels to check whether the photovoltaic panels are in normal working condition, including whether the photovoltaic panels are falling off, whether there is abnormal shading, whether there is cracking, and whether the photovoltaic brackets are damaged. Deformation, dumping, whether the direction of light is normal, etc. Generally, photovoltaic power plants cover a relatively large area, ranging from a few hundred acres to tens of thousands of acres. The workload of manual inspection is too large, and it can only be inspected by drone aerial photography. In photovoltaic power plants, photovoltaic modules ...
