Abstract

To measure accurately the attitude of a spatial object that was fast-changing in a suspension state,an attitude measurement method was proposed based on three linear CCD cameras for measuring multiple point cooperation targets.By proposed method,the nonlinear systemic errors and more calibration parameters caused by more overconstraints for camera positions were overcome in the traditional linear CCD attitude measurement.Three 1D cameras composed of linear CCDs and cylindrical lenses were used to measure simultaneously the multiple point cooperation targets on the measured object.Aiming at the restriction of measuring principle on the attitude angle,the simulated calculation method was used to calculate the attitude angle range and the BP neural network was taken to calibrate the CCD cameras and give the spatial 3D coordinates of point cooperation targets.Furthermore,an attitude calculation model based on Rodrigues parameters was established to solve the attitude angles of measured objects.Experimental results indicate that the measurement accuracy of spatial point position and the calculating precision of spatial attitude angle in this system are higher than those of traditional methods,which verifies that this attitude measurement method is feasible and available to measure the attitude.

Abstract

An exterior attitude calculation method by taking Rodrigues parmeter as the attitute representation parameter was presented to overcome the shortcomings of the constraints and complexity of traditional attitude calculation algorithms and to increase the real-time performance for the multi-linear CCD spatial object exterior attitude measurement system.A multi-linear CCD exterior attitude calculation model was deduced based on the high efficiency of the Rodrigues parameter and the relationship of the intersection vector between the line segments composed of point cooperation targets.In order to avoid the singularity in attitude calculation,a switching theory of the Rodrigues parameters is combined in the algorithm and the process of this attitude calculation method was also given.Experimental results indicate that the computational-complexity of the proposed algorithm is reduced by 37.6% as compared with that of the quaternion method on the premise of assuring precision, and it is superior to quaternion method in real-time performance.At the same time,it avoids the singularity problem.
