摘　　要：为了避免杂散光降低成像的质量,提出了基于激光扫描的杂散光数据传输优化方法。分析激光扫描过程中杂散光的来源,构建杂散光校正矩阵,通过抑制杂散光,避免杂散光在系统成像过程中产生影响,提高成像质量。度量激光扫描成像数据信息的码元相似性,并提取其特征,通过IIR滤波算法进一步处理,完成成像数据优化传输。实验结果表明,所提方法对杂散光的抑制能力强,数据传输吞吐量高,可将传输时延控制在10 s内,网络利用率为87%。In order to prevent stray light from degrading the imaging quality,an optimization method of stray light data transmission based on laser scanning is proposed.The sources of stray light during laser scanning are analyzed,and the stray light correction matrix is constructed to improve the imaging quality by suppressing stray light and avoiding stay light from affecting the system imaging process.The code element similarity of laser scanning imaging data information is measured and its features are extracted,and further processed by IIR filtering algorithm to complete the optimal transmission of imaging data.Experimental results show that the proposed method has strong ability to suppress stray light,high data transmission throughput,and can control the transmission delay within 10 s,and the network utilization rate is 87%.
