在地理位置标定和三维地图创建过程中,通常采用远程遥感位置标定方法.传统的地理遥感标定采用边缘检测和分水岭分割标记的方法,当地理空间色斑出现非显著性过渡时,标定效果不好.提出一种基于投影散斑尺寸配准的地理遥感标定技术.采用投影散斑尺寸配准技术,去除地表植被的色斑出现非显著性过渡干扰.保留了Harris角点检测算法的稳定性,算法融合了SURF算法尺度不变的特性,提高了地理遥感标定特征匹配精度和效率.仿真结果表明,采用该基于投影散斑尺寸配准的地理遥感标定技术,具有较强的抗干扰性能,对地理遥感特征点的标定准确,重复点较少,算法对尺度、光照及噪声有较好的鲁棒性,提高了地理信息遥感配准的精度和速率.

In the geographical position calibration and 3D map building process, usually adopts the method of calibration of remote sensing position. Geographical remote calibration method using edge detection and watershed segmentation marker is researched, when the geographical space appearance of spots of non significant transition when the calibration effect is not good. Proposes a projection Geographical remote calibration technique of speckle size based on registration. Using the projection speckle size registration techniques, calculation of projection speckle size information and retain the stability of Harris corner detection algorithm, algorithm fusion the characteristics of SURF algorithm is scale invariant, improve the Geographical remote calibration feature matching accuracy and efficiency. The simulation results show that using the pro-jection Geographical remote calibration technique of speckle size based on registration, has strong anti-interference perfor-mance, the calibration of remote sensing characteristics of geographic point accurately, repeat the point less, algorithm to scale, illumination and noise robustness of geographic information of remote sensing, it improves the registration accuracy and speed.
