摘　　要：针对激光美容仪温度探测报警系统存在数据采集精度低,导致报警效果不佳的问题,提出一种基于多重约束优化的双目相机标定方法。首先,对系统结构光模组的相机标定方法进行具体分析;然后基于相机镜头畸变问题,采用多重约束优化方法对相机标定过程进行优化;最终通过该方法提升采集热力图像质量。实验结果表明,相较于优化前的方法和其他方法,本方法可有效降低图像获取过程中的物体重建误差,图像中物体重构精度高达99.88%,与真实图像十分接近。由此说明,本方法可实现原始相机标定优化和热力图像采集质量提升,帮助报警系统采集到更高精度的热力图像报警信息,提升报警系统的敏锐性,进一步保障仪器的使用安全,具有一定的可行性。For the problem of low data acquisition accuracy,a binocular camera calibration method based on multiple constraints is proposed.Firstly,the camera calibration method of the structural optical module is analyzed,the camera calibration process is opti-mized based on the camera lens distortion problem,and the thermal image quality is improved.The experimental results show that compared with the optimization method and other methods,this method can effectively reduce the object reconstruction error in the im-age acquisition process,and the object reconstruction accuracy in the image is 99.88%,which is very close to the real image.There-fore,this method can realize the optimization of the original camera calibration and improve the quality of thermal image acquisition,help the alarm system to collect higher precision thermal image alarm information,improve the acuity of the alarm system,and further guarantee the safety of the instrument,which has certain feasibility.
