The following describes in detail a specific implementation manner of the method for marking a pile foundation and the related device in the embodiments of the present application by way of embodiments with reference to the accompanying drawings.
Exemplary method
Referring to fig. 2, a schematic flow chart of a method for marking a pile foundation in the embodiment of the present application is shown. In this embodiment, the method may include, for example, the steps of:
step 201: any pile foundation on the drawing image is marked by clicking or frame selection, the marked pile foundation is used as a pile foundation template, and the type of the pile foundation, the code of the pile foundation and the number N of the pile foundations matched with the pile foundation template are determined, wherein N is a positive integer greater than or equal to 2.
Because the drawing image of the construction project comprises a large number of pile foundations, if the pile foundations are marked by adopting a manual mode in the prior art, the work is tedious and tedious, the workload is huge, more manpower and energy are required to be consumed, and manual marking errors are very easy to occur; therefore, in the embodiment of the application, the workload of manually marking the pile foundation is reduced, and the automatic marking of the pile foundation on the drawing image is realized. Firstly, a pile foundation on a drawing image needs to be marked, the pile foundation is used as a pile foundation template, and the type, the code and the number N of the pile foundation corresponding to the pile foundation template are determined. Wherein, the pile foundation code indicates the preset code that this pile foundation type corresponds, and pile foundation quantity N indicates the preset quantity of the pile foundation that this pile foundation type that needs the mark corresponds.
Since the common pile foundation types in construction engineering include manual earth-digging piles, pipe-sinking cast-in-place piles, bored cast-in-place piles, anchor static pressure piles, long auger drilling cast-in-place piles, precast tubular piles and the like, the pile foundation in the pile foundation formwork belongs to one of the above pile foundation types. That is, in an alternative embodiment of the present application, the pile foundation type is an artificial earth pile, a pipe-sinking cast-in-place pile, a bolt-static pressure pile, a long auger drilling cast-in-place pile, or a precast tubular pile.
As an example, determining that the type of a pile foundation corresponding to a pile foundation template is 'manually excavated pile', the code of the pile foundation is 'a', and the number of the pile foundations is '63'; as another example, it is determined that the type of the pile foundation corresponding to the pile foundation template is "driven cast-in-place pile", the pile foundation number is "b", the pile foundation number is "13", and the like, and other examples are similar and are not described herein again.
Step 202: selecting a target area within the drawing image range, and setting an image in the target area as a target image;
step 203: intercepting a region image with the same size as the pile foundation template from one side boundary of the target region, moving a preset step length to the other side direction each time until moving to a second side boundary of the target region until traversing the target region, so as to identify and extract all region images with the same size as the pile foundation template in the target image;
step 204: carrying out image recognition processing on the region images in the target image based on the pile foundation template, and obtaining N non-overlapping region images containing pile foundations in all the region images through similarity calculation to serve as N pile foundation images;
in this application embodiment, after the pile foundation template is determined in step 201, the whole drawing image or part of the drawing image that can be selected in a flexible way is used as the target image, and the pile foundation is automatically identified on the target image through the image identification technology according to the pile foundation template until N non-overlapping area images including the pile foundation, which are the size of the pile foundation template, are obtained, and the mode greatly reduces the workload of selecting each pile foundation by manually finding the position frame of each pile foundation on the drawing image, so that a large amount of manpower and energy are saved.
Specifically, the image recognition processing of the target image based on the pile foundation template means: firstly, calculating the similarity between the area image with the size of each pile foundation template on the target image and the pile foundation template, wherein the higher the similarity between the area image with the size of the pile foundation template and the pile foundation template is, the higher the possibility that the area image with the size of the pile foundation template comprises the pile foundation to be marked is; then, the area images of the sizes of the multiple pile foundation templates are sequenced according to the similarity, the higher the similarity between the area image of the size of the pile foundation template closer to the front of the sequencing and the pile foundation template, the area images of the sizes of the front N non-overlapping pile foundation templates are selected from the area images of the sizes of the multiple pile foundation templates after the sequencing, the area images represent the area images of the sizes of the pile foundation templates which are most similar to and non-overlapping with the pile foundation templates, and the area images can be used as the N pile foundation images. Therefore, in an alternative implementation manner of this embodiment of the present application, the step 202 may include the following steps:
step A: obtaining the similarity between each area image on the target image and the pile foundation template;
and B: sequencing all the area images from high to low according to the similarity, and determining the first N non-overlapping area images which contain pile foundations in the sequencing;
and C: and extracting the first N non-overlapped area images containing the pile foundations in the sequence as N pile foundation images.
The image recognition processing mode can be OpenCV, and OpenCV is a cross-platform computer vision library issued based on BSD license (open source), and can be run on Linux, Windows, Android and Mac OS operating systems. The method is light and efficient, is composed of a series of C functions and a small number of C + + classes, provides interfaces of languages such as Python, Ruby, MATLAB and the like, and realizes a plurality of general algorithms in the aspects of image processing and computer vision. Of course, the embodiment of the present application does not limit the specific manner of the image recognition processing, and the manner of the image recognition processing may be freeform, CImg, CxImage, or the like.
The area images of the sizes of the plurality of pile foundation templates are actually obtained by sequentially intercepting the area images according to the size of the pile foundation template and a preset step length through traversing the target image. That is, in an optional implementation manner of the embodiment of the present application, the area images with the size of the pile foundation templates are obtained by first intercepting the area images with the size of the pile foundation templates from the upper left corner of the drawing image, and moving the area images with the size of the pile foundation templates to the right by a preset step length each time until the area images move to the right boundary of the drawing image; and moving the preset step length downwards from the left boundary of the drawing image every time, and repeatedly executing the step of moving the preset step length to the right boundary of the drawing image every time until the target image is traversed to obtain the target image.
In the embodiment of the application, the preset step length may be a preset moving step length, and for a drawing image, the preset step length is greater than or equal to one pixel; that is, in an optional implementation manner of the embodiment of the present application, the preset step size includes at least one pixel. For example, the preset step size may be specifically one pixel, or the preset step size may be specifically five pixels, and so on. The smaller the preset step length is, the more the number of the area images with the sizes of the pile foundation templates is, and the more accurate the image identification effect is.
As an example, a schematic diagram of obtaining multiple pile foundation form sized area images is shown in fig. 3. Firstly, intercepting an area image with the size of a pile foundation template from the upper left corner of a drawing image, and moving the area image to the right by one pixel each time until the area image moves to the right boundary of the drawing image; and moving downwards one pixel from the left boundary of the drawing image every time, and repeatedly executing the steps of moving downwards one pixel from the right boundary of the drawing image every time until the right boundary of the drawing image is moved until the target image is traversed to obtain a plurality of area images with the size of the pile foundation template.
It should be noted that, when the target image is large, the image recognition processing is directly performed on the target image, and it takes much time to traverse the entire target image, so as to further improve the efficiency of image recognition; in the embodiment of the application, the target image is divided into the plurality of target sub-images in a recursion mode, image recognition processing is conducted on the plurality of target sub-images based on the pile foundation templates in parallel, the recursion division parallel processing mode can obtain N non-overlapping area images with the size of the pile foundation templates as N pile foundation images, and processing time of image recognition is greatly shortened. Therefore, in an optional implementation manner of the embodiment of the present application, for example, the method may further include step C: recursively dividing the target image into a plurality of target sub-images; correspondingly, the step 201 may be, for example: and performing parallel image recognition processing on the plurality of target sub-images based on the pile foundation template to obtain N non-overlapping area images with the size of the pile foundation template as N pile foundation images.
As an example, the recursively dividing the target image into a plurality of target sub-images may be dividing the target image into 2 images, dividing each of the 2 divided images into 2 images, and so on to obtain a plurality of target sub-images.
Step 205: and marking the pile foundations in the N pile foundation images based on the pile foundation code and the pile foundation quantity N.
In this application embodiment, after obtaining N pile foundation images, the pile foundation that this pile foundation image includes is the pile foundation that needs to be marked, and the pile foundation indicates to carry out the pile foundation name according to pile foundation code and pile foundation quantity N in the pile foundation image in the mark pile foundation image substantially.
As an example, when the type of the pile foundation corresponding to the pile foundation template is "manual soil excavation pile", the code of the pile foundation is "a", and the number N of the pile foundations is "63", the pile foundations in the N pile foundation images may be sequentially marked as "a 1", "a 2", "a 3", … … "and" a63 "according to a preset sequence, and based on this, 63 manual soil excavation piles are represented on the image drawing; the preset sequence may be, for example, from left to right, or from top to bottom.
It should be further noted that, after marking the pile foundations in the N pile foundation images based on the pile foundation code and the number N of the pile foundations in step 205, marking data of the pile foundations in the N pile foundation images is formed, where the marking data is not fixed and may be adjusted accordingly based on requirements. Therefore, in an optional implementation manner of this embodiment of the present application, after the step 205, for example, a step D may further be included: and adjusting the marking data of the pile foundations in the N pile foundation images.
According to various implementation modes provided by the embodiment, firstly, a pile foundation template is determined in response to the operation of a pile foundation on a marking drawing image, and the type, the code and the number N of the pile foundation corresponding to the pile foundation template are determined; n is a positive integer greater than or equal to 2; then, carrying out image recognition processing on the target image based on the pile foundation template to obtain N non-overlapping area images which are the size of the pile foundation template and comprise the pile foundation as N pile foundation images; the target image is the whole drawing image or a part of the drawing image; and finally, marking the pile foundations in the N pile foundation images based on the pile foundation code and the pile foundation quantity N.
