Smart multispectral image acquisition and multi-channel image processing with programmable System on Chip devices

摘要

Through the acquisition and processing of several spectral channels within the multispectral data, the demands on signal processing and data handling increase enormously. With the help of intelligent signal pre-processing on programmable system on chip platforms (pSoC), captured data can be corrected and evaluated directly after image acquisition. PSoC combine the advantages of freely programmable logic (FPGA) and sequential processor systems (ARM technology) and significantly increase the integration density of embedded image processing systems. However, the design effort for these systems is increasing strongly, so that hardware/software co-design approaches must be used for implementation. The paper covers the design methodology, the implementation and the evaluation of multichannel acquisition systems using multispectral image sensors as an example.
