Problems solved by technology

The advantage of this type of binocular or multi-eye measurement system is high accuracy, but the disadvantage is that the system is huge, complex in structure, requires precise installation and calibration, relatively high power consumption, and requires high stability in the measurement environment. It is also relatively complicated, and data processing cannot be completed in real time on site, so it is difficult to apply to the field environment
In addition, conventional ch

Embodiment 1

[0085] Taking the landslide disaster rescue site in Wulong, Chongqing on June 5, 2009 as an example, the present invention is used to monitor and alarm potential landslide bodies (including rock slopes, soil slopes, dangerous rocks and rolling stones) at the rescue site.

[0086] 1. Place the monitoring and alarm device at an observation point 1,000 meters away from the landslide, and set the monitoring parameters through the designed and developed monitoring and alarm device control software, for example: the digital camera shooting time interval is 1 second, the pixel resolution of the monitoring image The monitoring rate is 4288×2848, the monitoring mode is manual selection of landslide body target or automatic monitoring, setting the alarm threshold of displacement and attitude change, etc.

[0087] 2. Taking images taken with a Nikon D90 SLR camera as an example, the scene of a landslide disaster is as follows: image 3 Shown:

[0088] 3. Multiple monitored landslide tar...

Embodiment 2

[0094] Taking the landslide disaster rescue site in Wulong, Chongqing on June 5, 2009 as an example, the present invention is used to monitor and alarm potential landslide bodies (comprising rock slopes, soil slopes, dangerous rocks, and rolling stones) at the rescue site, and the specific implementation steps as follows (see figure 2 ):

[0095] 1. Place the monitoring and alarm device at an observation point 1000 meters away from the landslide body;

[0096] 2. Use the matching monitoring and alarm software of the present invention to set the safety threshold and alarm parameters for monitoring; set the shooting time interval, shutter speed, image resolution, focusing mode, and shooting mode of the high-resolution camera installed with the telephoto lens ;

[0097] 3. Manually select the target of the landslide body to be monitored, or automatically select the target of the landslide body by the monitoring device; use the GPS positioning module to locate the monitoring an...

Abstract

The invention discloses a remote and rapid monitoring and alarming device and method for the displacement and the gesture of a sliding mass, and relates to a target monitoring technique. The method carries out remote automatic monitoring on the potential sliding mass in the earthquake and landslide disaster emergency rescue, and monitors the changes of the position and the gesture of the potential sliding mass, and once the changes reach or exceed the preset safety limit, the acousto-optic alarm is carried out to warn the field personnel to take safety measurements or depart from the danger area. The device has mature technique, lower cost, simple structure, low power consumption and higher accuracy, is convenient in operation, is convenient for outdoor monitoring, provides the insurance for natural disaster rescue, and generates enormous economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of target monitoring, and relates to a single digital camera-based device and method for long-distance rapid monitoring and alarming of the displacement and attitude of a landslide body. Background technique [0002] Entering the new stage of the new century, with the acceleration of economic and social development, the intensification of economic activities, the over-exploitation of natural resources, the sharp increase in population, and the deterioration of the ecological environment, the natural disasters in our country are showing an increasingly serious development trend. Work is facing severe challenges. Among the many natural disasters, earthquakes are disasters caused by local rapid rupture of the earth's internal medium. There are three main seismically active belts in the world, among which my country is located in the Circum-Pacific Seismic Belt and the Eurasian Seismic Belt, and China's Taiwan r...
