The invention relates to a video monitoring automatic glancing method and system for an aero-engine test. The method comprises the following steps: determining a to-be-glanded position of an aero-engine; the number and the scanning range of automatic scanning equipment are determined according to the position to be scanned; planning a glancing path based on the automatic glancing equipment, and setting a glancing strategy on the glancing path; and associating the glancing strategy with a test run program, and carrying out glancing according to the test run program. The existing video monitoring process is optimized through an automatic means, and the problems of low efficiency, incomplete monitoring, insufficient operation standardization and the like caused by manual operation are solved. By pre-determining the to-be-glanded position of the aero-engine and planning the automatic glancing path and strategy based on the positions, the invention realizes the standardization of the monitoring work. Manual operation is replaced by automatic glancing, errors and omissions caused by human factors are reduced, and the reliability and comprehensiveness of monitoring are improved.
