The invention relates to the technical field of
artificial intelligence, and discloses a low-illumination scene-oriented unmanned aerial vehicle
imaging data enhancement method, which comprises the following steps of: S1, acquiring unmanned aerial vehicle
imaging data and constructing a training
data set; s2, data preprocessing based on illumination partition; s3, constructing and training a data enhancement model; and S4, enhancing the
imaging data of the unmanned aerial vehicle. The data preprocessing based on the illumination partition in the step S2 comprises the following steps: generating a low-illumination area
mask and a medium-illumination area
mask based on the brightness information of the low-illumination image; a
Gaussian smooth
convolution operation is applied to the low-
illuminance region identified by the low-
illuminance region
mask to suppress
noise, and an original value is reserved for the medium-
illuminance region identified by the medium-illuminance region mask to generate a pre-processed image. The problems of low-illumination
image noise amplification and detail loss are solved by generating low-illumination region masks and medium-illumination region masks and respectively adopting
noise reduction and retention strategies, and the balance of dark region
noise reduction and bright region detail protection is realized.
