Abstract:Aiming at the problems of low detection accuracy, poor detection stability and long detection time in the detection process of the current coastline water area change detection system, a high-precision coastline water area change detection system based on satellite image technology is designed. STM32C8T6 is used as the main controller of the main control chip for efficient data processing and gateway communication. The multi spectral sensor is used as the core detection equipment to generate the image of coastline water area by collecting optical data. The external power supply with XL1509-5.0 chip as the core is used to supply the system power supply equipment, and the OUTPUT is used as the output pin of the power switch, which is convenient for the main controller to control the power supply and complete the system hardware design. The satellite image technology is used to filter, reduce noise and binary image calculation for the collected graphics, embed the Linux operating system and MySQL database, detect the collected images with high precision, complete the system software design, and realize the high-precision detection of changes in coastal waters. The experimental results show that the designed coastline water area change high-precision detection system based on satellite image technology has good detection stability, can effectively realize the high-precision detection of coastline water area change and shorten the detection time of coastline water area change.
