摘　　要：提出了一种基于尺度不变性特征变换的检测仪器面板关键数据精准定位方法,针对变电检测常用仪器在分辨率变化、角度变化、光线变化、雨水/积灰/泥土杂质干扰等状态下共1020张图片进行了关键数据定位测试。结果表明,该方法对以上干扰均具有良好的特征定位鲁棒性,对拍摄角度不超过45°的整体随机样本的特征定位准确率达96%以上,可用于复杂现场环境下变电检测仪器面板数据精准定位及提取辅助。A method for precise positioning of key data of detection instrument panels based on scale invariance feature transformation is proposed.Commonly used instruments for substation detection have a total of 1020 in terms of resolution change,angle change,light change,rain/ash/soil impurity interference,etc.A key data positioning test was performed on this picture,and the results show that the method has good feature positioning robustness against the above interference,and the feature positioning accuracy of the overall random sample with a shooting angle of not more than 45°is over 96%,which can be used for Accurate positioning and extraction assistance for panel data of substation detection instrument in complex field environment.
