| 摘 要： | 针对红外目标远距离识别特征微弱且具有很大不确定性的问题,定量研究了目标红外辐射强度提取精度与图像信噪比关系,并基于红外双波段比色测温原理,建立了目标温度特征提取与置信度估计模型。经静态实验验证,在图像信噪比达到6时,目标温度特征估计区间为10 K,特征估计精度为5 K；经外场试验验证,在图像信噪比达到6时,目标温度特征估计区间为20 K,特征估计精度为10 K。

| Abstract: | To solve the problem that infrared remote target recognition feature is weak and uncertain,the relationship between target infrared radiation intensity extraction accuracy and image SNR is quantitatively studied.Based on infrared dual-band temperature measurement principle,target temperature feature extraction and confidence estimation model are established.The static experiments show that when the image SNR reaches 6,the target temperature feature estimation interval is 10K,and the feature estimation accuracy is 5K.According to field test,when the image SNR reaches 6,the target temperature feature estimation interval is 20K.The feature estimation accuracy is 10K. |
