红外场景仿真系统的成像质量关系着仿真实验的质量。对红外场景生成装置的主要技术指标进行测评,主要包括时间特性、空间分辨率、空间均匀性、几何畸变等,这些指标可以全面反映仿真系统的技术性能。为了在实际应用过程中迅速、简洁地确定仿真系统的最佳工作状态,提出了一种客观评价算法,通过采用标准红外成像设备对仿真系统进行探测成像,与场景生成器所仿真的实物场景进行对比,实现对场景仿真系统的定性评价和标定。实际应用表明,该方法便于每次使用之前进行系统标定,可以快速、便捷确定仿真系统的最优工作状态。

The image quality of the infrared scene produced by dynamic infrared scene generator is directly related to the testing quality of the simulation system. The main technical parameters of infrared scene generation device include time characteristic, spatial resolution, spatial uniformity, geometric distortion and so on. These parameters can roundly evaluate the image quality of infrared scene generation device. In order to ascertain the best working condition rapidly and laconically in the process of practical application, a new approach is presented. Through adopting the normal infrared imaging device to detect and image for the simulation system, comparing to the scene of real object simulated by the scene generator, the qualitative evaluation and calibration of the scene simulation system is achieved. Actual application proves that this approach allows for system calibration before each use, and the optimal working condition of the simulation system can be easily and quickly obtained.
