Step10 后端计算服务(水色指数反演)
|
||||
====================================
|
||||
Step10 后端计算服务(水色指数反演 · 散点 CSV 模式)
|
||||
====================================================
|
||||
|
||||
纯计算函数——绝对不引用 PyQt、绝对不引用 main_view、绝对不读写全局变量。它只:
|
||||
|
||||
1. 从 ``config`` 字典读取参数;
|
||||
2. 调用 ``WaterIndexProcessor.run_inversion`` 用 ``waterindex.csv`` 中的
|
||||
公式直接处理去耀斑 BSQ 影像,输出各水质参数指数的 GeoTIFF;
|
||||
3. 返回结果字典 ``{status, output_path, message, mode}``。
|
||||
2. 调用 ``WaterIndexCsvProcessor.compute_indices_from_csv``
|
||||
读取 Step 4 输出的 ``sampling_spectra.csv`` 散点,对每行采样点
|
||||
套用 ``waterindex.csv`` 中勾选的公式,输出每公式一个 CSV;
|
||||
3. 返回结果字典 ``{status, output_path, message, mode, ...}``。
|
||||
|
||||
调用入口(由 main_view 在后台 QThread 中调用):
|
||||
|
||||
execute_step10({
|
||||
"bsq_path": "D:/deglint_output.bsq", # 去耀斑 BSQ 影像(必填)
|
||||
"deglint_img_path": "D:/deglint_output.bsq", # 同上(兼容旧 panel 字段)
|
||||
"hdr_path": "D:/deglint_output.hdr", # ENVI 头文件(可省,自动 .bsq→.hdr 推断)
|
||||
"selected_formulas": ["NDCI", "BGA_Am09KBBI"], # 要处理的公式名列表(空 → 全部)
|
||||
"formula_csv_path": "D:/waterindex.csv", # waterindex.csv 路径(可省,自动探测)
|
||||
"water_mask_path": "D:/water_mask.dat", # 水域掩膜路径(可省)
|
||||
"nodata_value": -9999.0, # NoData 标记值
|
||||
"output_dir": "D:/10_WaterIndex_Images", # 输出目录(可省 → work_dir/10_WaterIndex_Images)
|
||||
"enabled": True,
|
||||
"work_dir": "D:/workspace", # 工作目录(main_view 注入)
|
||||
"sampling_csv_path": "D:/4_sampling/sampling_spectra.csv", # 必填
|
||||
"selected_formulas": ["NDCI", "BGA_Am09KBBI"], # 勾选公式;空 → 全部
|
||||
"formula_csv_path": "D:/waterindex.csv", # waterindex.csv 路径
|
||||
"output_dir": "D:/10_WaterIndex_CSV", # 输出目录;可省
|
||||
"enabled": True,
|
||||
"work_dir": "D:/workspace", # 主窗口注入
|
||||
})
|
||||
|
||||
返回字典字段:
|
||||
|
||||
* ``status`` : "completed" | "skipped" | "error"
|
||||
* ``output_path`` : 输出目录路径(失败时为 None)
|
||||
* ``output_files`` : {公式名: 公式 CSV 路径}(失败时为空 dict)
|
||||
* ``message`` : 人类可读说明
|
||||
* ``mode`` : "watercolor_inversion"(便于 UI 提示)
|
||||
* ``mode`` : "watercolor_inversion_csv"(便于 UI 提示)
|
||||
|
||||
设计要点
|
||||
========
|
||||
- 与 Step 9 (ML 预测) 完全对称的"散点处理模式":输入 CSV、输出 CSV,
|
||||
坐标列重命名为 longitude/latitude,公式值以列形式追加。
|
||||
- 旧"读 BSQ 全图 → 输出 GeoTIFF"模式已废弃(科学上误差大且与 GIS 栅格计算器重复)。
|
||||
- 兼容调用方可能仍传旧键(bsq_path / hdr_path / deglint_img_path),检测到时
|
||||
静默忽略并回退到 sampling_spectra.csv 路径解析(避免破坏已有 pipeline 配置)。
