Paper Abstract

To solve the question of monocular pose measurement of the non-projected-axisymmetric targets, a Contour Image Length matching method is proposed,firstly,the contour of the targets is simplified as many triangles based on nose to solve the information redundancy and visual occlusion;secondly,the simplified target is projected to the image plane to get virtual image length,the actual image length is extracted simultaneously, then the pitch, yaw and roll angle can be obtained by length matching between virtual image and actual image. The aircraft flight calibration test shows that the precision of the pitch angle, yaw angle and roll angle was 0.9 degrees,1.2 degrees, and 1.5 degrees respectively, which indicated the result is slightly lower than intersection, but can save cost and improve efficiency. Finally, the key factors concerning method error are analyzed; the method can lay an important foundation for monocular pose measurement in range.
