A carrier rocket video image interpretation error correction method

The invention discloses a carrier rocket video image interpretation error correction method. The method belongs to the technical field of spaceflight measurement and control, and comprises the following steps of firstly, tracking and measuring video imaging data of a vertical take-off section of a carrier rocket by a high-speed television measuring instrument, selecting any one characteristic point on the carrier rocket to obtain angle measurement data of two side edges of a measurement ring of the characteristic point in an observation station coordinate system, and performing error correction to obtain a corrected angle. According to the method disclosed by the invention, after the bilateral interpretation error is corrected, the transverse drift and the attitude of the carrier rocket can be accurately calculated, the flight state of the rocket is prevented from being mistakenly estimated, and an accurate and reliable data basis is provided for analyzing the rocket model and evaluating the flight performanc
