Referring to fig. 1, a flowchart of a method for measuring a water line according to an embodiment of the present application is shown, and a specific implementation flow of the method is as follows:

step 100: acquiring an original image containing a water level gauge; the water level gauge is a tool for measuring a water level line; step 101: image interception is carried out on the original image, and a plurality of partial images containing the water level gauge are obtained; step 102: based on the classification model, identifying each local image to obtain a target local image containing a water line; step 103: and determining the position of the target water level line according to the target partial image.

In one embodiment, for water level identification, image acquisition is typically performed for a water level bar, and an original image containing the water level bar is obtained. Alternatively, the image may be a single picture or a video frame.

The water level gauge is a tool for measuring the water level line, and the height of the water level line can be measured through the scales of the water level gauge.

In one embodiment, to increase the efficiency of the water line measurement, the implementation of step 101 may include:

s1011: and carrying out water level identification on the original image to obtain a water level area.

Alternatively, the water level gauge area may be marked by a polygonal frame such as a rectangular frame.

In one embodiment, the original image is subjected to water level identification to obtain a rectangular frame containing the water level.

S1012: according to the water level area, image interception is carried out on the original image to obtain a plurality of partial images; overlapping areas are included between adjacent partial images.

In one embodiment, a polygon image, i.e., a partial image, having a side length of a specified side length (e.g., 224 mm) is taken with a center line of a water level area (e.g., rectangular frame) from top to bottom as a path, and a specified number of pixels (e.g., 20 pixels) as a step length.

In one embodiment, to accurately determine the partial image in which the water line is located, the implementation process of step 102 may include:

s1021: and inputting each local image into a classification model to obtain the confidence coefficient of each local image.

In one embodiment, a classification model is built and trained in advance based on a neural network, and each local image is classified through the pre-trained classification model, so that the confidence coefficient of each local image is obtained.

Alternatively, the confidence level may be in the interval range of [ -1,1], and if the confidence level is greater than 0, the local image is determined to be located above the water line, otherwise, the lower the water line, the closer to 1, and the higher the probability of being above the water line, and conversely, the lower the probability.

S1022: and screening out target confidence degrees positioned in the set confidence degree interval from the confidence degrees.

The confidence interval may be set to be higher than the first confidence threshold and lower than the second confidence threshold.

In practical application, the confidence interval and the first confidence threshold value, and the second confidence threshold value can be set according to the practical application scene, which is not limited herein.

Further, one confidence coefficient with the confidence coefficient closest to 0 can be screened out from all confidence coefficients larger than zero, one confidence coefficient with the confidence coefficient closest to 0 can be screened out from all confidence coefficients smaller than zero, and the two screened confidence coefficients are determined to be target confidence coefficients.

For example, the confidence of each partial picture is [1,1,0.9,0.9,1,0.8,0.4,0.3, -0.4, -0.5, -0.8, -0.9, -1, -1] in order. The confidence levels 0.3 and-0.4 may be determined as target confidence levels.

S1023: and determining the local image corresponding to the target confidence as a target local image.

In one embodiment, to accurately determine the target water line location, the implementation of step 103 may include:

s1031: if the target partial image is one, determining the image height corresponding to the target partial image as the target water line position.

In one embodiment, a water level scale corresponding to a center point of a target partial image is read as an image height.

In one embodiment, the image height corresponding to the target partial image is determined according to the correspondence between the original image and the length of the water level and the position (e.g., order, scale, etc.) of the target partial image in the original image.

S1033: if the target partial images are multiple, determining the position of the target water line according to the image height corresponding to each target partial image.

In one embodiment, an average of a plurality of image heights is calculated as a target water line position.

In practical application, the determination mode of the target local image may be set according to the practical application scene, which is not limited herein.

In one embodiment, early warning can be performed in time when the water level line is high. The implementation process of step 103 may further include:

performing mark recognition on the original image to obtain an early warning position; and if the target water line position and the early warning position in the original image are determined to be in accordance with the early warning condition, sending out early warning information.

In one embodiment, the pre-warning position in the original image is compared with the target water line position, and if the target water line position is higher than the pre-warning position, pre-warning information is sent out.

In one embodiment, a difference between the pre-warning position and the target water line position in the original image is calculated, and if the difference is located in a set pre-warning interval, pre-warning information is sent out.

For example, if the difference between the target water line and the pre-warning position is higher than a first preset difference (e.g., 2), the pre-warning information is sent.

For another example, if the difference between the pre-warning position and the target water line is lower than the second preset difference (e.g., 2), the pre-warning information is sent.

In one embodiment, a plurality of set early warning intervals are set, corresponding early warning strategies are set for the set early warning intervals respectively, then the difference between the early warning position in the original image and the target water line position is calculated, the set early warning interval to which the difference belongs is determined, and early warning information is sent out according to the early warning strategies corresponding to the set early warning intervals.

Optionally, the early warning strategy may include at least one of: short messages, voice, ringtones, lights, and telephones.

Therefore, the position of the water level line can be accurately measured, the measuring step of the water level line is simplified, the cost of measuring the water level line is reduced, and early warning can be timely carried out.
