The application provides a disc area structure level determination method and device and electronic equipment. A first area containing a disc area is scanned line by line to obtain OCT volume data. A center point of the first area is taken as a center to star-type sample the OCT volume data to obtain a first number of first BScan two-dimensional section image data. An initial center point of the disc area is determined, and the OCT volume data is star-type sampled with the initial center point as the center to obtain a second number of second BScan two-dimensional section image data. The structure level of the disc area is determined. The OCT volume data is obtained in a line-by-line scanning manner, which ensures a high sampling rate. The sampled data is uniform and continuous. Star-type sampling is performed on the continuous data, which can avoid jumping and errors. In addition, the initial center point of the disc area is determined through star-type sampling, and then star-type sampling is performed with the initial center point as the center, which can obtain a more accurate disc area structure level.

The invention relates to a planet identification method based on a KASP marker. The planet identification method comprises the following steps: (1) carrying out surface disinfection on a plant sample to be tested; (2) grinding the disinfected plant leaves into powder by using liquid nitrogen; (3) extracting the genome DNA of the sample, adjusting the DNA concentration to 5-50ng / mu L, and storing at 4 DEG C for later use; (4) selecting a specific SNP (Single Nucleotide Polymorphism) site on the basis of comparing the ppc-1E1c sequences of the astrophe plants; (5) designing two forward primers and a reverse primer according to the SNP site; (6) respectively adjusting the concentrations of the three primers to 36 [mu] M, 36 [mu] M and 90 [mu] M, and mixing the three primers according to a volume ratio of 1: 1: 1 to form a primer mixed solution; (7) preparing a reaction solution according to a reaction system: 5 [mu] L of template DNA, 5 [mu] L of KASP mastermix and 0.14 [mu] L of the primer mixed solution, and setting a negative control; (8) performing amplification according to a PCR program; and (9) judging whether the sample is a planet plant or not according to a fluorescence typing result. The method is rapid, accurate, low in cost and suitable for species identification, germplasm resource identification and molecular marker-assisted breeding of planets.

The present application provides a kind of geostationary orbit plane array camera on-orbit star extraction method and system, comprising: according to the principle of stationary orbit satellite plane array imaging, cold air is star area in the periphery of earth disc chart, and star image slides through camera field of view according to the direction from west to east;According to the basic data of star library, combined with satellite orbit, attitude data and imaging condition, the time of star appearing in field of view and the corresponding angle of camera two-dimensional scanning mechanism can be calculated;In actual star observation process, camera two-dimensional scanning mechanism is pointed to the predetermined position in advance according to the corresponding angle of predetermined observation star, and waits for star to appear;After star enters field of view, try to keep star in field of view range, star moves stably in plane array camera field of view, and continuously adjusts two-dimensional scanning mechanism angle along with the motion track of star, to keep continuous observation to star whole track process.
