Optimization of High Speed Target Test Algorithm Based on Monocular Laser Digital Photography System
To improve the measurement accuracy of objects moving at ultrahigh speeds, a correction amount δ is added to optimize the traditional calculation model based on analyzing the test process of a high speed photography system. Combining the two models before and after optimization, the theoretical and actual trajectory velocities of moving objects are simulated under different speed intervals, correction amount δ, distance between camera reflection screen hz, and other important parameters. The analysis shows that the proposed model exhibits accurately corrected movements of high speed and ultrahigh speed objects, and the correction effect improved with the increasing model speed. Analyzing the relationship between the distance and the measurement error reveals that when the hz value is greater than 30 m, the relative deviation is less than 1%. The field test results are consistent with the proposed calculation model and simulation model.
