| 摘 要： | 针对由于经纬仪的成像质量受环境因素影响较大,其测量图像目标定位能力难以评估的问题,根据测量图像处理的要求,提出了一种基于目标边缘灰度梯度的测量图像目标定位能力评估方法.该方法将目标边缘范围内的灰度梯度幅值统计量作为评估指标,实验证明,该方法所用的指标能准确地反映测量图像的质量,且计算简单,易于快速实现.

| Abstract: | Because of environmental influence,the image of an optical theodolite usually has low quality,and the target-localization ability is difficult to evaluate.In this paper,an evaluation method for the target-localization ability of measured images is proposed.The method uses the amplitude statistics of gray grads in edge regions as evaluation parameters.Experimental results demonstrate that the evaluation parameters used by this method can nicely reflect the quality of images,and the computation is simple and ... |
