The invention discloses a wide dynamic unmanned aerial vehicle imaging screening evaluation method and
system, and the method comprises the steps: building an unmanned aerial vehicle
image evaluation system based on a monitoring image preset standard, and carrying out the image collection of a monitoring region through an unmanned aerial vehicle; performing OECF, resolution, color, shadow and
distortion evaluation on the acquired image through an
evaluation system; inputting the preprocessed image data into a neural network, and performing
feature extraction on the image data acquired in real
time based on the neural network; normalization
processing is carried out on the
system extraction characteristic values, and an image grade model is built. Through evaluation results of five indexes of ECF, resolution, color, shadow and
distortion of an unmanned aerial vehicle image, screening transmission is carried out on the unmanned aerial vehicle shot image in combination with multi-index
weight analysis, so that the data volume required to be processed by subsequent analysis can be greatly reduced, the overall working process is accelerated, and the working efficiency is improved. And the hard disk capacity of the unmanned aerial vehicle or
cloud storage resources in other forms can be saved.
