The application discloses a laser radar oblique photogrammetry device and its surveying and mapping method, wherein the laser radar oblique photogrammetry device includes a measuring device body and a mounting seat, and a mounting plate is detachably connected to the measuring device body, and the mounting plate and the mounting seat A plurality of vibration-damping reset mechanisms are provided; the vibration-damping reset mechanism includes: a first vibration-damping assembly, which includes a slide bar and a sleeve, and the ends of the slide bar and the sleeve are respectively hinged to the mounting seat and the mounting plate, and the slide bar is elastically Set in the sleeve, the sleeve is provided with a calibration piece for driving the slide bar to return to the initial position accurately; the second damping assembly includes a connecting rod hinged on the sleeve, and the end of the connecting rod is slidably arranged on the mounting seat On the mounting base, there is a second shock absorber for elastically arranging the end of the connecting rod on the mounting base. The application has the effect that the measuring device body is quickly and accurately reset to the initial position after being shaken, thereby ensuring the measurement accuracy of the measuring device body.
Description
technical field [0001] The present application relates to the field of lidar and photogrammetry, and in particular, to a lidar oblique photogrammetry device and a surveying and mapping method. Background technique [0002] Surveying and mapping refers to the measurement, collection and drawing of natural geographic elements or the shape, size, spatial location and attributes of artificial facilities on the surface, which can be used for engineering construction, planning and design, and administrative management. And with the continuous development of UAV technology, aerial surveying and mapping methods are very popular. By installing the surveying and mapping device on the UAV, the area to be surveyed and mapped can be accurately measured with an accuracy of up to 5cm. [0003] The Chinese patent document with the publication number CN111880562A in the related art proposes a UAV ground imitation flight device based on lidar; it includes a UAV body, a high-definition camera ...
