Abstract

In consideration of the effect of radiometric specification of a mapping camera on the matching accuracy of imaging

the quantification of main radiometric specifications are analyzed

and the mathematical model between them is developed to provide theoretical foundations for determining the specifications of the mapping camera. Firstly

Least Squares Image Matching Algorithm (LSIM) is deduced mathematically

and then the main factors impacting matching accuracy are presented

including the scene characteristics

Modulation Transfer Function (MTF) for an imaging system

Signal to Noise Ratio (SNR) and Radiometric Distortion (RD) metrics. Then

the image degradation owing to the above factors is modeled and simulated. Based on LSIM

the mathematical model between matching accuracy and radiometric specifications is developed using Genetic Algorithm and Back-propagation Neural Network (GABPNN). Finally

the model is verified using simulated images and on-orbit images. Experimental results indicate that the model precision is less than 0.01 pixels. It suggests that when the MTF

is set to be greater than 0.08

SNR greater than 45 and RD less than 4% based on the model

the error of matching accuracy can be less than 0.1 pixel.
