Embodiment 1

[0028] A dry beach monitoring method based on photogrammetry and laser ranging, comprising the following steps:

[0029] Step 1: Use the remote automatic camera system to calibrate the industrial camera and regularly take photos of the dry beach;

[0030] Step 2: According to the dry beach photos, use the waterline automatic recognition algorithm to accurately position the waterline;

[0031] Step 3: Use the precise control servo system to adjust the angle of the laser ranging device so that the laser ranging device is aligned with the identified precise waterline position;

[0032] Step 4: The laser distance measuring device automatically measures the distance from the waterline to the laser lens, and obtains the length of the dry beach through geometric conversion.

[0033] The watershed algorithm is used in the waterline automatic identification algorithm. The watershed algorithm is an image region segmentation method. During the segmentation process, pixels that are simi...

Abstract

The invention provides a dry beach monitoring method based on photogrammetry and laser ranging. The dry beach monitoring method comprises the following steps: 1, correcting an industrial camera by using a remote automatic photographing system, and periodically photographing a dry beach photo; 2, using a waterline automatic identification algorithm to accurately identify the position of the waterline according to the dry beach photo; 3, adjusting the angle of a laser ranging device by using an accurate control servo system so that the laser ranging device is aligned with the identified accuratewaterline position; and 4, automatically measuring the distance from the waterline to the laser lens by the laser ranging device, and obtaining the length of the dry beach through geometric conversion. The image recognition system, the laser ranging system and the accurate control servo system are integrated, and the laser ranging device automatically measures the distance from the waterline to the laser lens by automatically identifying the waterline and accurately controlling the servo system to adjust the angle of the laser ranging device, and automatic measurement of the dry beach lengthis realized.

Description

technical field [0001] The invention relates to the technical field of dry beach monitoring, in particular to a dry beach monitoring method based on photogrammetry and laser ranging. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. The tailings pond is a high potential energy man-made debris flow hazard, and there is a danger of dam failure. Once the accident occurs, it is easy to cause serious accidents. At present, the number of tailings ponds in my country is large and widely distributed. Many tailings ponds have been in operation for many years, and the capacity of the tailings ponds is gradually decreasing. The ability to resist natural disasters continues to decline, and safety hazards are increasing. The safety of tailings ponds is related to the safety of people's life,...
