摘　　要：推动铁路货车装载状态图像质量的提升,除了运用各种方法提升系统运行性能外,对系统生成的图像质量进行有效评价也是非常必要的手段。图像质量评价指标是评价方法的核心,需要针对铁路货车装载状态图像特点,综合考虑评价方法的客观性和实用性,确保在实际应用中取得良好的效果。清晰度、畸变度和亮度3项指标直接影响图像的视觉效果和可视性,从这3项指标建立有效的铁路货车装载状态图像质量评价方法,能够帮助提高人眼、机器对图像的视觉体验和分析能力,确保车站货检值班员能够有效利用图像采集设备检查通过列车的货物装载状态,加强预检工作。To improve railway wagon loading status image quality,various methods can be used to improve the system’s operational performance,and the effective evaluation of the quality of the images generated by the system is necessary.Image quality evaluation indicators are the core of the evaluation method.According to the characteristics of railway wagon loading status images,the objectivity and practicality of the evaluation method need to be comprehensively considered to ensure good results in practical applications.Sharpness,distortion,and brightness indicators directly affect the visual effect and visibility of images.Establishing an effective evaluation method for railway wagon loading status image quality based on the above three indicators can help improve the visual experience and analysis of images by human eyes and machines and ensure that station freight inspection duty officers can use image acquisition equipment to inspect the freight loading status of passing trains and strengthen pre-screening work.
