Tilt photography is a high-tech developed in the field of international surveying and mapping in recent years. It subverts the limitations of previous orthophotos that can only be taken from a vertical angle. By carrying multiple sensors on the same flight platform, and simultaneously capturing images from five different angles of one vertical and four tilts, the user is introduced into the human eye. The true and intuitive world of vision. The aerial tilt image not only can truly reflect the ground object, but also can embed precise geographic information, richer image information and more advanced user experience through advanced positioning technology, greatly expanding the application field of remote sensing image and making remote sensing image. Industry applications are deeper. The introduction and application of tilt imaging technology will also greatly reduce the cost of current high-dimensional 3D urban modeling.
