This paper expatiates the course of Image Mosaics with 8-parameter perspective transformation algorithm in detail. 本文详细阐述了基于8-参数透视映射图像拼接算法的实现过程。
A set of coordinates calculation equations between the object space and the image space were set up according to reverse perspective projection transformation, and equation of plane of the calibration target was educed. 经图像分析确定特征圆圆心及直径在像面上的透视投影位置和长度,根据透视投影逆变换原理建立物和像空间坐标关系的解算模型,进而导出靶面平面方程。
It uses vehicle-mounted camera to get road image information and uses position device to get vehicle location information. Then it uses inverse perspective transformation to produce road orthophoto fragment and uses offline interpolation algorithm to handle the position information and splice the fragments together. 该方法使用车载摄像头和定位设备采集路面图像信息和车辆定位信息,并使用逆透视变换等坐标变换方法和线下插值算法分别处理图像和定位信息,生成正射影像碎片。
The paper mainly introduces how to get the parallel image from the lean image using the conditions of geometry and restriction in the surface of building according to the theory of perspective transformation. 提出了获取建筑物大比例尺立面影像的一种理论与方法。根据数字相机倾斜影像,利用建筑物外观的几何条件与约束条件,按照透视变换原理,导出相应关系式,直接获取相同主距的平行影像。
