采用条纹管激光成像系统的激光偏振成像是对现有的条纹管激光三维成像的进一步延伸,如果在充分利用该成像系统获得的强度像和距离像的基础上,再加上偏振信息,则能实现对目标高精度的探测和识别。对采用条纹管的激光偏振成像进行了初步的实验研究,提出了两次测量的偏振成像实验方法,处理了实验中获得的几种特定目标的条纹图像,得到了目标的强度像和偏振度图像,并进行了比较。结果表明:偏振度图像比强度像对比度高,克服了光源辐照不均匀的缺点。证实了偏振成像的可行性,为完善成像实验系统,提出了用一次测量就能完成偏振成像的实验方法,融合强度像和偏振度图像的处理方法将实现对目标更高精度的探测。
The laser polarization imaging using the striped tube laser imaging system is a further extension of the existing three-dimensional imaging of the striped tube laser. If the intensity image and the distance image obtained by the imaging system are fully utilized, the polarization information can be added Achieve the target of high-precision detection and identification. A preliminary experimental study on the laser polarization imaging with streaked tube was proposed. Two experimental methods of polarization imaging were put forward. The streak images of several specific targets obtained in the experiment were processed and the intensity and polarization images of the target were obtained. , And compared. The results show that the polarization degree image has higher contrast than the intensity image, which overcomes the shortcoming of uneven irradiation of the light source. The feasibility of polarization imaging is confirmed. In order to improve the imaging experiment system, an experimental method of polarization imaging with one measurement is proposed. The fusion intensity image and polarization image processing method will achieve the target with higher accuracy.
