激光距离选通成像门宽对图像信噪比影响
Effect of gate width of laser range gating imaging on image SNR
摘要
Abstract
The experiment system to analyze the image SNR with different gate width was used in this paper for confirming the range gating imaging SNR with different laser range measuring accuracy.First of all,the system parameters were determined according to the coverage model of the laser range gating imaging.On the basis of that,the experiment system was established and the outdoor experiment research was made with this system. The comparison analyzing of different gate width image also was made,and the curve of the relation between gate width and image SNR was obtained.The final experiment result indicates that the image SNR ≥8 with gate width ≤2 μs can satisfy the requirement of auto recognition,which indicates that the range gating ima-ging system has no very strict requirement to the range measuring accuracy,and can satisfy the practical appli-cation requirement.关键词
