Method for correcting guide current error code in image transmission

Abstract

The invention discloses a correction method of deflector ring error code in image transmission of an optical imaging system. The method utilizes RS (Reed Solomon) code as the algorithm of error-correcting code, selects a RS code parameter according to the actual size of transmitted image and the error-correcting requirement, and then designs the relevant error-correcting code and decoding module according to the selected parameter and the transmission characteristic of deflector ring, thereby realizing the correction of deflector ring error code during the image transmission. The invention has the advantages that the invention can efficiently correct the burst error during the image transmission of deflector ring in time, ensure the image data obtained by the optical imaging system to be correctly transmitted to the receiver terminal, and ensure the original image to be restored for the next analysis and treatment.

Description

technical field

[0001] The invention relates to the technology of error correction encoding and decoding in image transmission, in particular to a method for correcting code errors of a diversion ring in image transmission, which is applied to an image transmission system of an omnidirectional optical imaging system. Background technique

[0002] In an omnidirectional imaging system, such as an omnidirectional infrared imaging system, since the infrared imaging system continuously performs 360° rotating imaging, the acquired images are usually transmitted through a guide ring. The diversion ring is composed of several rings, and each ring transmits one bit of image information. Due to the manufacturing process and long-term mechanical friction, the surface of the guide ring is prone to slight damage or fine dust, which will cause errors in the image data of tens or even hundreds of bits continuously transmitted on a certain ring. If these error codes cannot be corrected in ...
