Embodiment

[0051] Step 1: The airglow image of the upper atmosphere is captured by the CCD camera and the original image is input into the SD card (such as figure 2 shown);

[0052] Step 2: Embed the SD card in the card slot 10 of the FPGA development board 1;

[0053] Step 3: Nios II embedded processor 2 obtains the image information from the SD card, and generates a digital image matrix and stores it in the SDRAM memory 4. The specific method is: the image information is decoded to obtain the gray value of each pixel, and the The positions of these gray values ​​are in one-to-one correspondence with the row and column positions of the matrix to generate a digital image matrix, image 3 is the gray value of some pixels in the digital image matrix;

[0054] Step 4: Perform noise elimination, center calibration, and ring division processing on the digital image matrix in step 3, and average the gray value on each ring to obtain a binary number composed of the ring serial number and the...

Abstract

The invention discloses an image processing system, comprising an FPGA development board based on a Nios II embedded processor, an SDRAM controller, an LCD controller, a digital tube controller and a JTAG controller are arranged in the FPGA development board, and the JTAG controller passes through Connect the USB‑Blaster cable to the PC. The method of obtaining the temperature of the upper atmosphere is to find out the data closest to the theoretical value in the measured value by comparing the measured value with the theoretical value, and the temperature corresponding to the closest data is the atmospheric temperature. Compared with the previous computer processing method, the processing rate is significantly improved, and it can be processed automatically without manual work. The Nios II embedded processor makes the circuit design more diversified, software functions are easier to add and delete, hardware resource configuration is flexible, and portability is better. Strong, and the development cycle of this method is short; the original fit image captured by the CCD can be directly decoded without converting the format, which ensures the complete image information and improves the calculation accuracy.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, relates to an image processing system, and also relates to a method for obtaining high-level atmospheric temperature by using the system. Background technique [0002] From the mid-1980s to the early 1990s, the external structure of the card-type image card tended to be miniaturized. By inserting the image card into the computer, it can form an image acquisition system with the computer. Since the early 1990s, image processing equipment has gradually been divided into two categories, one is still using plug-in cards, and with the maturity of PCI bus technology, it will replace products using ISA bus interfaces; the other is using large-scale image cards. An integrated circuit or application-specific chip that replaces a computer's offline image processing system. In the 21st century, digital image processing technology has received extensive attention in many application fields,...
