Embodiment Construction
[0051] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0052] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.
[0053] As documented in related technologies, direct inspection uses the ground actual measurement data as parameter data to inspect remote sensing products, but the acquisition of ground actual measurement data is difficult, the coverage is limited, and the calculation method is complicated, which is not suitable for fast, large-scale, long-term Engineering a...

The application provides an inspection method, device, electronic equipment and storage medium for a remote sensing reflectance image. The method includes: acquiring image data of the image to be inspected, the image data including time data, spatial data and spectral parameters; , match the image to be inspected with the preset first reference sample point set, and obtain the second reference sample point set that matches the image to be inspected in time and space; based on the spectral parameters, the image to be inspected and the second reference sample point set Spectral matching is performed on the point set to obtain target points that match the spectrum of the second reference sample point set; based on the relative reflectance error between the target point and the second reference sample point set, the authenticity of the image to be checked is determined. This embodiment can determine the second reference sample point set suitable for the current geographic location and image acquisition time from the first reference sample point set in a wide range, so as to realize a wide range of applications and realize the authenticity check of the reflectance image.
Description
technical field [0001] The present application relates to the field of computer technology, in particular, to a method, device, electronic equipment and storage medium for inspecting remote sensing albedo images. Background technique [0002] Authenticity testing of remote sensing products such as leaf area index, temperature and vegetation coverage, and evaluation of the accuracy and uncertainty of remote sensing products are important to improve the quantitative production level of remote sensing products, thereby improving the accuracy of remote sensing applications and expanding their application scope. means. At present, the authenticity inspection methods of remote sensing products are mainly direct inspection and cross inspection. [0003] Direct inspection uses ground measured data as parameter data to test remote sensing products. However, the acquisition of ground measured data is difficult, the coverage is limited, and the calculation method is complicated, which...
