Such as figure, the water gauge with " E " character pattern is elongated cylindrical, and it is sudden and violent to be generally disposed at field lake, river, city The horizontal line of the monitoring water levels such as rain position, " E " character pattern on water gauge is horizontally disposed, and vertical line is perpendicular to the water surface, adjacent " E " character Scale number is marked between pattern, to indicate water level value.That is, in water level measurement method of the invention, the use of setting In environment, " E " character pattern is had on water gauge, horizontal line and vertical line with standard may be used as the label of identification, be not necessarily to Set specific identifier.And when setting up water gauge, the corresponding height of water level of " E " character pattern on water gauge is via scale Digital representation comes out, and the photo Direct Recognition of shooting goes out " E " character pattern you can learn that corresponding scale number, water level value is just It is very clear.
Certainly, when actual measurement, some technical problems needs still overcome, it below will be to this further specifically It is bright.As shown, water level measurement method of the invention includes the following steps:
Step A: image preprocessing step: the image in the water gauge photo is carried out at median filtering and image equilibration Reason removes local noise and enhancing contrast in described image, to obtain preliminary examination altimetric image.I.e., it is contemplated that the water gauge of input The shooting environmental of image is field river, lake, and the scenes such as (under viaduct) at urban waterlogging monitoring, weather environment is uncontrollable Factor, fine day, cloudy day, rainy day etc..Therefore, median filtering first is carried out to image and image equilibration is handled, remove image local Noise and enhancing contrast, achieve the effect that amplify water gauge feature.
Step B: to the advanced row color extraction of the preliminary examination altimetric image, binary image is converted it into;Detect described two " E " character pattern in value image, position of " E " character pattern on water gauge described in record.Due to " E " character figure on water gauge Case is usually obvious with the background color difference of water gauge, and to avoid shade, dirt, water plant etc. from causing image interference, water gauge image is converted At binary image, so that biggish " E " character pattern of difference can carry out numeric ratio pair by digitized mode.Example Such as, in binary image in post-conversion, theoretically for, the numerical approximation of background color is identical, and the numerical value of " E " character pattern is also close Patibhaga-nimitta is same, but background color numerical value and " E " character pattern have biggish numerical difference, by by pixel each in binary image Numerical value is compared, and can will detected with respect to apparent " E " character pattern of background color numerical value difference, on the water gauge in pattern, Each " E " character pattern can be detected by way of traversing each pixel, obtain " E " character pattern on water gauge Position.
Certainly, the numeric ratio of simple binary image to may in light condition poor, spot and the more feelings of water plant Under condition, sizable detection error is formed, for exclusive PCR, improves detection accuracy, the invention also provides pass through engineering The mode of habit, the method for forming the training data for comparison.Specifically, the present invention can further include following steps:
In advance by multiple preliminary examination altimetric images obtained by step A, color extraction is first carried out, binary picture is converted it into Picture;100 complete " E " character pictures are intercepted on the binary image, as the positive sample of machine learning training, simultaneously It intercepts 2000 at random on the binary image and does not include the background image of " E " character as negative sample;To described positive and negative Sample carries out size normalized, and to the respective Haar-like feature of all sample extractions and saves;It will be described positive and negative The Haar-like feature of sample, which is input in the Adaboost classifier constructed, to be trained, and training data is obtained.It is above to be The method and step of training data for formation of the invention for comparison, this method step mainly use Adaboost classification to combine The machine learning mode of Haar-like feature detects visible " E " characters all on water gauge image.
In the forming process of above-mentioned training data of the invention, difference can be collected in for trained preliminary examination altimetric image Water gauge set up position, be used to compare acquisition sample is more, source is more extensive, the precision of the training data formed is got over 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.
