Abstract
Multi-mode Airborne Digital Camera System (MADC) was developed by Institute of Remote Sensing Applications and Shanghai Institute of Technical Physics in 2006. The system is enhancing and optimizing further now. It could realize three modes of wide field, multispectral, and stereophotography based on three 4K*4K CCD digital cameras in the course of taking aerial photography. Several finished aerial experiments have already demonstrated that the system has good performance for aerial photography; both the software and the hardware of MADC could work stably and reliably. Multispectral mode is a popular imaging way in airborne remote sensing. It can obtain multi-bands remote sensing images by using several digital cameras synchronously. The multispectral images can make use for various remote sensing applications, such as environment monitoring, resource researching, military use, and so on. In some special conditions, images which get by using less than 10nm bandwidth narrowband filters can be treat as hyperspectral images; so that we can consider the multispectral imaging way is a new approach for hyperspectral bands selection and data acquisition. In this paper, we will mainly discuss the following questions for the multispectral mode of MADC: the design principle, the basic arithmetic or model, the installation mode, the corresponding aerial experiments, the application fields and the ways of multitspectral images processing. At the same time, some important accessorial devices of MADC are also introduced. The point and conclusion will be received based on the practice installation, operation, ground and aerial experiments.
