چکیده انگلیسی
In order to acquire multispectral images precisely and quickly, a four-band multispectral capturing system with one imaging sensor is designed and evaluated in this paper. Firstly, four imaging bands are arranged in a 2Ã2 multispectral filter array (MSFA), and their filter spectral transmittances within the visual wavelength are designed uniformly. Then, the mosaicked four-band image is generated on the single-sensor according to the designed MSFA. In order to recover the mosaicked images, a demosaicking algorithm based on constant hue assumption is employed to highly maintain the image edges. At last, the four-band spectral capturing system is characterized by using the calibration target Macbeth ColorChecker, and a linear relationship between the band values and spectrum are calculated based on polynomial regression method, afterwards the demosaicked four-band pixels can be converted into the multispectral reflectance with that obtained relationship. In the experiment, the four-band multispectral imaging system with the proposed demosaicking algorithm is evaluated, and the experiment result demonstrates the proposed algorithm outperform the other methods in PSNR and RRMS.
