先前开发的SedImaging测试可快速确定粗粒土壤的粒度分布（PSD）。该测试包括拍摄和分析通过水沉淀后的土壤，以按大小对其颗粒进行分类。通过SedImaging生成PSD所需的时间是传统筛分所需时间的一小部分。由于体积和重量较大，原始SedImaging设备仅适用于实验室环境。因此，一个新的FieldSed系统已被设计为原来的SedImaging系统的现场适应版本。虽然它使用与原始SedImaging测试相同的Harr小波图像分析方法，但FieldSed使用更小规模的轻量级硬件，使其适用于任何测试环境。FieldSed还支持执行多个并行测试，从而大大缩短测试时间。FieldSed生产的PSD与筛分结果非常匹配。
A previously-developed SedImaging test quickly determines the particle size distribution (PSD) of coarse-grained soils. The test involves photographing and analyzing a soil following sedimentation through water to sort its particles by size. Generating a PSD by SedImaging takes a fraction of the time required by traditional sieving. Due to its large size and weight, the original SedImaging device is suitable only for laboratory settings. Therefore, a new FieldSed system has been designed as a field-adaptable version of the original SedImaging system. While it utilizes the same Harr wavelet image analysis methods as the original SedImaging test, FieldSed uses smaller-scale, lightweight hardware to make it practical for use in any testing environment. FieldSed also enables many parallel tests to be performed, thus greatly reducing testing time. The FieldSed-produced PSDs match sieving results very well.
