QMap - 拼接合并

 通过图像分割，得到许多子图像，分别处理后可再次将他们合并。同时，还可将其它图片汇总一起显示，调整各图像的“位置X”和“位置Y”，改变显示点。用鼠标左键点击预览图像，查看各图像之间的关系。

现按软件功能界面介绍如下：

1. 载入图像
    点击“载入图像”按钮，选择多个图像，在列表框中显示与编辑。如果图像文件名符合我们分割图像时的命名规则，则会自动算出坐标，确定在合并图像中的显示位置。

2. 列表框编辑
    列表框中的图像显示时，如果“位置X”和“位置Y”的值相同，则后图像覆盖前图像，可点击“▲”或“▲”按钮，改变图像在列表框中的位置，避免被覆盖。用鼠标左键双击“位置X”和“位置Y”下的值，可编辑后更新，改变子图像在合并大图像上的显示位置。

3. 合并显示
    点击“合并显示”按钮，将列表框中的图像按“位置X”和“位置Y”显示排列在预览图中，同时，新建窗口显示合并总图。

4. 查看分割情况
    用鼠标左键点击预览图，则鼠标点击下的对应分割图像便在新窗口中显示出来。

5. 对GMap格式图像的支持
    GMap格式是本软件独创的文件格式，它支持本软件几何纠正后带有大地坐标的图像。当选择“GMap格式”时，所有GMap格式图像按大地坐标排列，而其它图像按列表坐标排列。默认时不选择GMap格式。

6. 保存或载入列表
    通过调整合并图像的列表，得到了各种匹配关系。点击“保存列表”按钮，可将列表框中的数据保存到文件，需要时通过“载入列表”恢复列表。

 Image resizing is the overall scaling of an image to suit different applications. Now according to the software function interface, the introduction is as follows: 1.  Select image      Right-click on the image to select the image. At the same time, the original size (width and height) of the image is rendered in the edit box. 2. Bound ratio      By default, select " Bound ratio ", modify the width of the edit box, the corresponding height will be changed according to the aspect ratio of the original image, and vice versa. The image can also be changed out of proportion, resulting in distortion. 3.  Process     Click the " Process " button to process. To restore the original image, click the " Restore " button (Ctrl+Z) on the toolbar. Back to www.ccqmap.com

QMap - Geodetic Control Point (GCP) Geometric fine correction

Image
The purpose of geometric correction is to map an image without geodetic coordinates to a given coordinate system. Through mapping transformation, it can eliminate the deviation of image geometric position caused by various factors, such as extrusion, stretching, distortion and offset, etc. It is especially suitable for remote sensing images and stitching of various super large images. Through geometric correction, precise positioning images of various geographic information can be established, which makes the analysis of historical changes with time as the axis very convenient. Now according to the software function interface, the introduction is as follows: 1. Load control point file     Click the "Load" button to load the selected geodetic control points with features. The control points to be selected are listed in the list box at the top of the dialog. 2. Match Control Points      Click an item in the list box at the top, and the details are listed in the ed...
