Description
Technical field
The present invention relates to the method for early warning of Urban Storm Flood, especially a kind of for carrying out the flooding area early warning of rain flood in city
Method.
Background technique
Due to city low laying areas in heavy rain impeded drainage, often will form Urban Storm Flood flooding area.Flooding area vehicle
Personnel's passage has biggish security risk.Therefore it needs to survey the rainwater water level and the depth of water of rain flood flooding area in heavy rain
Amount, and by the publication of real-time depth of water situation on professional website and public Internet site.

2, it is that relationship is most between dyke elevation that traditional river water level measurement, which is concerned with water level and flow, especially water level,
To be close, therefore water level major embodiment is height value;And Urban Storm Flood flooding area more concerned be flooding area the depth of water
Have mostly deep, if can be open to traffic, if can walk etc., existing level measuring can not provide this type of information.
3, the early warning of rain flood flooding area and the early warning of flood are entirely different.Rain flood flooding area in city can all be covered with municipal administration
Pipe network, when heavy rain occurs, all city planting ductworks can all intake, and many times rain flood flooding area is in more low-lying in city
Area, rainwater cannot be discharged from drainage pipeline networks, many times can even flow backward from the pipe network on highland to the pipe network of low land, make
Become water inlet pipe at drainpipe, and when heavy rain reduces, drainpipe just starts to play a role, but since the blocking runner of sundries is past
It is past unsmooth.When heavy rain occurs, also can not accurately be obtained by the water (flow) direction of traditional mathematical simulation calculation pipeline in water-break
Obtain drainage speed, therefore forecasting and warning time inaccuracy.

Height, it is representative better, it can be widely applied to the detection of " E " character pattern of the various water gauges with " E " character pattern.Namely
Sample of the present invention for training, it is not limited to which specific water gauge position is also not limited to the specific time, as long as by various
After the image of the water gauge of " E " character pattern carries out binaryzation, can be formed using above-mentioned same training method can be used for this hair
The training data of bright or other detection techniques, the training data have a wide range of application, and precision is high, can be used to obtain more accurate
Testing result.
After obtaining training data, the image for needing to identify first carries out binaryzation, enters step B later and is detected, inspection
When surveying in the binary image " E " character pattern, the trained data are read in, traverses in whole image and meets the instruction
The position of " E " character feature in the data perfected, as described position of " E " character pattern on water gauge.
Step C: according to position of " E " character pattern on water gauge, the position of " E " character center point topmost is obtained
It sets.30 pixel distances are extended to the X-coordinate (abscissa of horizontal direction) of the position to the left, extend up 60 pixels, from
And determine the origin position in water gauge region;Further according to water gauge shared Pixel Dimensions on the image, water gauge part is finally extracted
Image.The key of this step is the top image for obtaining entire water gauge, to obtain the top termination of water gauge, to as water gauge
Identification origin, cause identification error with to avoid blocking at the top of water gauge.
Step D: straight-line detection is carried out to the water gauge topography using Hough line detection algorithm, obtains institute in region
Some straight line set;According to the testing result of " E " character, straight line is screened, is only retained straight in all " E " character ranges
Line;Straight line is screened according to slope, is only retained close to vertical straight line;Y coordinate is (vertical on all straight lines after acquisition screening
The ordinate in direction) maximum value and minimum value, and vertical straight line is done with any one X-coordinate position in " E " character range, it obtains most
The water gauge line more than whole water surface, to obtain the Y coordinate pixel value of the intersection of the water surface and water gauge.
Step E: shooting a water gauge image after camera and water gauge are all fixed, obtains water gauge pixel value and its corresponding
Actual value simultaneously saves;The data of preservation are fitted by the way of fitting of a polynomial, obtain water gauge pixel value and actual value
Between relation formula.
The step is the parameter calibration that the relation formula of water gauge pixel value and actual value is obtained by manually mode in fact
Process.Just it has been observed that due to when setting up water gauge, the corresponding height of water level of " E " character pattern on water gauge is via quarter
Degree word shows, and the photo Direct Recognition of shooting, which goes out " E " character pattern, can know corresponding scale number, so
And scale number needs are gone out by photo array and are manually judged, it cannot accomplish image automatic identification process.Therefore, this step
Suddenly a parameter calibration step is provided, i.e., a water gauge is shot after camera and water gauge are fixed for each water gauge position
Image can identify the corresponding real water level of each pixel value on water gauge in advance by computer or manual type
These correspondence numerical value are saved carry out fitting of a polynomial, the relationship between available water gauge pixel value and actual value by value
Formula, that is, one can pass through the parameter calibration formula of machine automatic comparison.
Step F: it by relation formula obtained by calibrating in the substitution of Y coordinate pixel value described in step D step E, calculates
To final water level value.
