提出了一种实用的适用于无人值守设备的红外弱小多目标自动判读方法。通过判别图像序列段累积信号量的变化进行目标段自动定位，对定位后的目标段运用轨迹预测关联的方法进行目标识别。给出了目标图像序列的处理结果，证明该自动判读方法可以在保证目标识别率的同时大大缩短图像判读时间，能够满足光电测量中快速提供测量结果的需求。

A practical method for unattended equipments to auto-interpret IR dim and small multitargets is introduced. The automatic positioning of a target segment was performed by discriminating the cumulated target signal change in image sequences,and then the target recognization was implemented by using trace forecasting correlation in the target segments.The processing results for some target image sequences were presented. It is proved that this method can reduce the image interpretation time and ensure the target recognition speed.
