At present, there is no precedent for applying this method to the field of reservoir bank deformation monitoring.
[0010] The landslide disaster that may be caused by the slope deformation of the reservoir bank in the river basin is a huge potential threat to the construction and operation of hydropower projects, the safety of people's lives and property, and the surrounding ecological environment. The development of close-range photogrammetry methods and technologies has brought new opportunities for the development of bank slope deformation monitoring of water conservancy and hydropower reservoirs.

Embodiment Construction
[0031] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] Such as Figure 1 to Figure 3 Shown, the present invention is based on the river basin bank deformation close-range photogrammetry monitoring method of water mobile platform, mainly comprises following 5 steps:
[0033](1) Determine the bank slope of the watershed to monitor deformation. Firstly, determine the scope of the watershed where the project is located, and determine the start and end locations of the measurement and monitoring watershed.
[0034] (2) Route planning and design. According to the determined range of the watershed and the starting and ending positions of the monitoring, combined with the close-range measurement principle and engineering experience, the centerline of the river is used as the navigation track of the survey ship, and the survey ship sails along the track to realize simultaneous monit...

The invention belongs to the research field of safety monitoring, relates to the integration of an inertial navigation system, GPS data information acquisition equipment and photographing devices, measurement ship route planning and designing and close-range photogrammetry monitoring methods, and discloses a watershed reservoir bank deformation close-range photogrammetry monitoring method based onan overwater mobile platform. The method is characterized in that a measurement ship, on which cameras are fixed, carries out overwater mobile photographing according to a designed route, and the device integration is achieved through an inertial navigation IMU and a GPS signal receiving device, so that the purpose of watershed reservoir bank deformation close-range photogrammetry monitoring is achieved. Through the method, overwater unmanned equipment close-range photogrammetry can be achieved, so that the development of the watershed reservoir bank deformation monitoring technology can be promoted.
Description
technical field [0001] The invention relates to the technical field of engineering safety monitoring, in particular to a method for close-range photogrammetry monitoring of river basin bank deformation based on a mobile platform on water. Background technique [0002] Reservoir bank deformation refers to the displacement of the reservoir bank slope in different directions under unstable conditions. Once the large-scale displacement of the bank slope causes the slope to slide and form a slope disaster, it will pose a huge threat to the construction and operation safety of water conservancy and hydropower projects. At the same time, it will increase the cost of project construction and maintenance, delay the construction period, and affect the normal use of the reservoir. In addition, it will also cause the loss of life and property of the people downstream of the reservoir area, and damage the surrounding natural environment. Therefore, the application requirements for slope ...
