Problems solved by technology

These are some simple preventive measures, relying on the most primitive human and material resources. Although they have played a preventive role to a certain extent, they are a waste of financial resources during the implementation process and lack real-time performance.

Embodiment Construction

[0023] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0024] refer to figure 1 and figure 2 , the present embodiment takes rock rolling as an example, the method involves an image acquisition system, an image analysis system, a microcontroller, and an acousto-optic alarm system. system connection.

[0025] In the dangerous rocky area, the objects that do not change in position, such as trees, towers, and mountain tops, are abstracted as fixed points, and two points that can form a triangle with the monitoring target are selected as the reference points of the monitoring target. In the image acquisition system, a digital camera is used to collect images, a certain shooting frequency is set for the camera, the captured images are sent to the image analysis system, and the angle formed by the monitoring target and two fixed points is calculated and stored in the database. Then th...

Abstract

The invention discloses a method for judging tumbling or landslide of rocks. The method includes the following steps: (1) choosing rock region where dangers exist; (2) setting a pictorial information collection system, so that the monitoring range covers the dangerous region; (3) objects which are still in position and a monitored object are abstracted as fixed points, and two points are selected to form a triangle with the monitored object and as reference points of the monitored object; (4) a hazardous maximum range after tumbling of the rocks is simulated by utilization of a geographic information system (GIS) software and an alarm system is arranged within the range; (5) an image analysis system is connected with the image connection system and sends analysis results to a micro controller, and a control signal is sent out by the micro controller to control a sound-light alarm system.

Description

technical field [0001] The invention relates to a method for judging rock rolling or landslide, which belongs to the field of information technology, especially the field of image information analysis technology. Background technique [0002] China has a vast territory and complex geographical conditions, and natural disasters occur frequently, including earthquakes, typhoons, landslides, mudslides and other natural disasters, which occur every year. Many of the disasters can also lead to secondary disasters, such as earthquakes, landslides, etc. can cause rocks to roll down. After these disasters, the rocks are easy to loosen. Even if there is no rolling phenomenon at that time, they are easily separated and broken due to weathering, corrosion, folds and fractures. Under the action of wind force, temperature drop, etc., it will collapse and form rolling stones. [0003] In recent years, with the frequent occurrence of natural disasters, the phenomenon of rolling rocks oft...
