The significance of photo overlap
By overlapping parts, stereoscopic observation and measurement can be carried out, and more accurate geographical information can be obtained. In photogrammetry, three-dimensional observation can be realized by overlapping several adjacent photos, and then three-dimensional landform and feature information can be obtained. At the same time, overlap can also be used to connect photos, so that images can be seamlessly connected to form a continuous image area.
Overlapping is also helpful to correct possible measurement errors and deformation, and improve the accuracy and accuracy of mapping. Therefore, it is necessary to overlap enough photos in photogrammetry, which can provide complete data and reliable results and provide effective support for the acquisition and application of geographic information.
