Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] Please refer to figure 1 , the invention provides a kind of rice automatic change detection method of integrated pixel and object, it is characterized in that, comprises the following steps:
[0032] Step S01: Construct the MODIS water body index time-series data set of the start year and the end year of the study area, and then establish the MODIS water body index time-series curves of the start year and the end year respectively pixel by pixel;
[0033] The water body index LSWI was calculated by using the 8-day maximally synthesized MODIS band reflectance data. A total of 46 phases of 8-day maximally synthesized MODIS data in one year. The period-by-period calculation is based on the MODIS water body index, and the MODIS LSWI time-series data within the year is obtained.
[0034] Based on the MODIS LSWI time series data within a year, and u...
