The application discloses a distributed adaptive framing output method based on large-range remote sensing images, and relates to the technical field of remote sensing image processing. The preprocessed large-range remote sensing images are stored in a COG format, the framing size and quantity are dynamically adjusted in combination with the target area range and resolution, the tasks are distributed by a data locality perception scheduler after Z-order curve sorting, the computing nodes load the framing data with a buffer area, the framing data is interpreted by a random forest, and the buffer area is cropped, finally, the virtual data set is aggregated, efficient distributed parallel processing of the large-range images is realized, the I / O bottleneck and the computing resource limitation are effectively relieved, the context missing problem on the framing boundary is solved, the intelligent interpretation efficiency and precision are improved, and the multi-resolution on-demand rendering and elastic expansion are supported to adapt to the data scale growth.

This invention discloses a blood culture detection system based on spectral reflectance technology, comprising: a culture container for culturing samples; a sensor for sensing the sample state and changing color according to changes in the sample state; a light signal acquisition component for projecting single-wavelength light onto the sensor and receiving the reflected light signal after reflection by the sensor; and a reading module for obtaining a reading result indicating whether the sample is infected based on the received reflected light signal; the light source is used to project at least two different colors of single-wavelength light onto the sensor. This invention also discloses an alarm method for the blood culture detection system based on spectral reflectance technology. The blood culture detection system and alarm method of this invention, based on spectral reflectance technology, improve the accuracy of positive rate readings by using different wavelength light sources for detection.

This invention belongs to the field of electrical and magnetic variable measurement technology, specifically involving a method for measuring and identifying electromagnetic response electrical parameters based on linear background stripping and morphology-related parameters. The method involves a preset moving identification window width; within the selected window range, early and late multi-channel electrical responses of equal time periods are extracted from the first and last channels, respectively, and the summation and average are used to generate early and late characterizing multi-channel electrical responses; linear background removal is performed on the early and late characterizing multi-channel electrical responses to obtain early and late multi-channel abnormal morphology vectors; the correlation coefficient of the early multi-channel electrical responses with the late abnormal morphology is calculated to obtain the induced electromotive force (ICF) response identification factor at the center of the window; the window is moved point by point to obtain the distribution of ICF response identification factors corresponding to the overall data profile and normalized; the distribution and intensity characteristics of the ICF response in transient electromagnetic data are identified through its amplitude distribution, effectively improving the accuracy of ICF response identification in transient electromagnetic data.
