摘要
基于透视投影变换,提出了一种新的激光自准直测角系统建模方法,通过对系统安装误差因素和模型外参数的仿真分析,提出了一种带有内外参数的激光自准直简化测量模型,为激光自准直测角系统建模、标定等问题的解决提供了一个有效的理论依据,具有一定的理论意义和工程实际应用价值.
Based on the theory of perspective projection transformation, a new modeling method /or laser auto-collimation angle measurement system is proposed. By simulating and analyzing the installation errors of the measurement system and the outer parameters of the measurement model, a simplified mathematical model of laser auto-collimation angle measurement is established, which includes the inside and outer parameters. The model can be regarded as an available theoretical reference for the system calibration of laser auto-collimation angle measurement or the establishment of the measurement model. Thus it is significant in theory and is valuable in engineering applications.
