A binocular vision stereo matching method and storage medium based on regional feature extraction, wherein the binocular vision stereo matching method includes: obtaining a first image and a second image under two viewpoints; setting a first pixel point in the first image, expanding other pixels distributed around the first pixel point with similar textures to form a first texture area, and obtaining a third image using the first texture area and the unexpanded area outside; setting a second pixel point in the second image, forming a second texture area by expanding similar textures and obtaining a fourth image; cost aggregation of any pixel point in the third image or the fourth image according to a preset cost function and a plurality of preset disparity values, so as to obtain the best disparity value of the pixel point from each disparity value. This method can overcome the disadvantage that the low texture content matching process between the two images is prone to errors, and greatly improve the performance of the binocular vision stereo matching algorithm.

The application provides a method for improving the linear range of a latex-enhanced turbidimetry kit and the latex-enhanced turbidimetry kit, and relates to the technical field of analysis and detection. The application finds that sodium deoxycholate is added to reagent 1 of the existing latex-enhanced turbidimetry kit. Experimental verification shows that the correlation coefficient of the existing latex-enhanced turbidimetry kit can be effectively improved, and the upper limit of the detection linearity of the latex-enhanced turbidimetry kit is improved to 500 mg / L, thereby effectively alleviating the problem that the linear range of the reagent of the existing latex-enhanced turbidimetry kit is narrow, and 90% of the sample amount in the clinic cannot be covered, so as to affect the accuracy of the clinical detection result.

The present invention relates to the field of meteorological radar technology, and specifically to an X-band dual-polarization phased array rain radar system and detection method. The system includes hardware equipment, a processing module, and auxiliary accessories; the hardware equipment includes an antenna array subsystem and a radar base subsystem; the processing module includes a polarization channel consistency calibration submodule, a particle phase identification submodule, and a rainfall estimation submodule; the auxiliary accessories include power supply equipment, a generator, lightning protection facilities, an optical fiber network, and a data storage device. A planar microstrip patch array antenna is used, which is designed with a spacing arrangement and has the characteristics of small area and high phase center consistency, ensuring high consistency, low side lobes, and high cross-polarization isolation of dual-polarization beams; at the same time, the detection accuracy is improved by setting a processing module.
