[0051] see figure 1 ,Such as figure 1 As shown, the embodiment of the present application discloses a schematic flowchart of a hyperspectral band selection method. Such as figure 1 As shown, the method of the embodiment of the present application includes:
[0052] 101. Read the band data and mineral composition data of the hyperspectral ground features;
[0053] 102. Determine whether the data volume of the band data and mineral component data measured by the hyperspectral ground features exceeds the memory of the host, and if it exceeds, the band data and mineral component data of the hyperspectral ground features are measured according to the preset threshold Perform data block;
[0054] 103. Construct a hyperspectral band selection model combining data parallelism and task parallelism according to the block data;
[0055] 104. According to the hyperspectral band selection model, the band data and mineral component data of the segmented hyperspectral ground features ar...
Embodiment 2
[0083] see image 3 , image 3 It is a schematic structural diagram of a hyperspectral band selection device disclosed in an embodiment of the present application. Such as image 3 As shown, the device of the embodiment of the present application includes:
[0084] The reading module 201 is used to read the band data and mineral composition data of the hyperspectral ground objects;
[0085] Judgment module 202, for judging whether the data volume of the band data and the mineral composition data of the hyperspectral surface object actually measured exceeds the memory of the host computer, if exceeding, then according to the preset threshold value, the band data and the mineral composition data of the hyperspectral surface object actually measured Mineral components for data block;
[0086] A construction module 203, configured to construct a hyperspectral band selection model combining data parallelism and task parallelism according to the block data;
[0087] The data pr...
Embodiment 4
[0098] The embodiment of the present application discloses a storage medium, the storage medium stores a computer program, and the computer program is executed by a processor to select the hyperspectral band selection method disclosed in the first embodiment of the present application.
[0099] The storage medium of the embodiment of the present application judges whether the data volume of the band data and the mineral composition data of the hyperspectral ground features actually measured exceed the memory of the host, and then can perform the measurement of the hyperspectral ground features measured band data and data according to the preset threshold. Mineral component data block According to the preset threshold, the data of the band data and mineral components measured by the hyperspectral ground features are divided into data blocks and read into the host in sequence, so that the hyperspectral band combined with data parallelism and task parallelism can be constructed Se...
