Example one
Fig. 1 is a flowchart of a method for measuring a line path of a power distribution line according to an embodiment of the present invention, where the method is applicable to a case where a line path of the power distribution line is determined without direct contact, and the method may be performed by a device for measuring a line path of a power distribution line, where the device for measuring a line path of a power distribution line may be implemented in a form of hardware and/or software, and the device for measuring a line path of a power distribution line may be configured in a mobile terminal such as a mobile phone, a tablet computer, a wearable device (e.g., a smart watch, smart glasses, etc.), or a computer device such as a server, a workstation, a personal computer, etc. As shown in fig. 1, the method includes:
and S110, acquiring initial image information of the distribution line with the line diameter to be measured.
The distribution line is a line for transmitting power from a step-down substation to a distribution transformer or transmitting power from a distribution substation to a power consumption unit. In the effective operation process of the whole power system, the main function of the distribution line is to transmit and distribute electric energy, and the performance of the distribution line directly influences the stability of electric energy transmission and the safety of electric energy used by users. Therefore, the construction of the distribution line requires safety and reliability, the power supply continuity is kept, the line loss is reduced, the power transmission efficiency is improved, and the good power quality is ensured.
In the distribution line, as can be seen from the resistance formula of the conducting wire, the larger the cross-sectional area of the conducting wire is, the smaller the resistance of the conducting wire is, and the wire diameter of the distribution line is an important factor influencing the resistance of the conducting wire. The wire of same material, the wire resistance that the sectional area is big for the sectional area is little, and under the unanimous condition of transmission load, the wire electric energy loss that the sectional area is little is great relatively, consequently, needs reasonable planning distribution lines 'line diameter size to distribution lines, based on electric power transmission's load size reasonable maintenance distribution lines. And further line loss determination is carried out on the area with serious line loss in later maintenance, wherein the size of the line path of the distribution line is one of more important parameters.
The method for measuring the line diameter of the distribution line mainly comprises the steps that at present, workers visually observe the distribution line based on work experience and adopt a measuring tool to perform contact type measurement after power failure processing is performed on the distribution line. The realization of the modes has the problems of low measurement result precision or relatively high cost caused by the influence on the normal operation of the power distribution network.
In specific implementation, initial image information of the distribution line with the line diameter to be measured is acquired by means of an image acquisition device. For example, for a power distribution line with a line diameter to be measured, an image acquisition device is held by a worker to acquire an image of the power distribution line at a certain distance from the power distribution line. The image acquisition device can be a camera, a video camera or other image acquisition devices. The distance between the image acquisition device and the power distribution line is selected to ensure the identification degree of the power distribution line in the acquired image information, namely, the distance between the image acquisition device and the power distribution line is required to be as close as possible under the condition of ensuring the personal safety of workers, so that the information quantity of the acquired initial image information is enough to support subsequent processing.
And S120, acquiring distance information between the acquisition device and the distribution line when the initial image information is acquired, wherein the acquisition device is used for acquiring the initial image information.
In concrete implementation, when acquiring initial image information, the distance between the image acquisition device and the distribution line needs to be acquired, and the acquired distance information is associated with the initial image information, so that the distance information during acquisition of each initial image information can be ensured to correspond.
For example, a distance acquisition assembly can be further arranged on the acquisition device, the acquisition device is used for acquiring initial image information of the distribution line, meanwhile, distance information between the acquisition device and the distribution line is acquired, and the acquired distance information and the initial image information are stored in an associated mode.
And S130, determining the size of the line path of the distribution line based on the initial image information and the distance information.
In the embodiment of the invention, the distance information between the acquisition device and the distribution line and the initial image information of the distribution line are obtained in the previous step. In this step, the size of the line path of the distribution line is calculated and determined based on the distance information and the initial image information.
In a specific implementation, for the determination of the size of the line path of the distribution line, since the initial image information and the distance information of the distribution line are obtained in the foregoing steps, the size of the distribution line in the initial image information can be obtained from the initial image information, and then the size ratio between the size in the initial image information and the size in the real world can be obtained based on the distance information, so as to obtain the real size of the line path of the distribution line.
Or before judging the size of the line diameter of the distribution line, acquiring the image information of the distribution line with each size of the line diameter under the condition of the distance between the fixed acquisition device and the distribution line, and establishing an image database. And then, judging the line path size of the distribution line by utilizing a pre-collected image database and the initial image information. For example, the initial image information is corrected by using the acquisition distance when the image database is established and the distance information of the initial image information, the initial image information is scaled to be consistent with the image database, and then image matching is performed to determine the line path size of the distribution line.
In the embodiment of the invention, the initial image information and the distance information of the power distribution line with the line diameter to be measured are acquired, then the line diameter size of the power distribution line is determined based on the initial image information and the distance information, the direct contact between a measurement worker and the power distribution line can be avoided by adopting acquisition equipment to acquire the initial image information of the power distribution line in a non-contact manner, the personal health of the measurement worker is effectively ensured, the power failure processing of the power distribution line is not required by the non-contact acquisition, the normal work influence on the power distribution line is effectively avoided, the actual line diameter size of the power distribution line is calculated based on the initial image information and the distance information, and the reliability of the line diameter size of the power distribution line obtained by measurement under the non-contact condition is effectively ensured.
In the embodiment of the present invention, specific implementation manners for determining the size of the line path of the distribution line based on the initial image information and the distance information may be various, for example:
matching the initial image information with a gallery image in a pre-established database to obtain a gallery image with the size consistent with the size of the initial image information line path, and further obtaining the size of the line path corresponding to the distribution line based on the information of the gallery image.
The method specifically comprises the following steps:
s131, correcting the initial image information based on the initial image information and the distance information to obtain target image information.
In concrete implementation, when the initial image information of the power distribution line with the same line diameter size is obtained, the distance between the acquisition device and the power distribution line is different, the size of pixels occupied by the power distribution line in the obtained initial image information is different, the pixel space occupied along with the increase of the distance is smaller, and the pixel space occupied along with the decrease of the distance is larger. Therefore, when the database is established, images of distribution lines with various line diameters at different distances need to be acquired to establish the database so as to ensure the data coverage rate of the database. When the size of the line path of the distribution line is specifically determined, the image of the gallery of the database with the same distance between the acquisition device and the distribution line in the distance information is matched to serve as a matching target, the size of the line path is matched, and then the size of the line path of the distribution line is determined.
In the embodiment of the invention, the initial image information is corrected based on the initial image information and the distance information before matching, namely, the initial image information is scaled to a certain extent based on the distance information, so that the distance information of the target image information obtained after correction is consistent with the acquisition distance of the gallery image in the database, thereby effectively reducing the workload of database establishment and effectively reducing the size of the database.
That is, when the gallery image is created in the database in S131, the initial image information is scaled based on the acquisition distance of the gallery image and the distance information of the initial image information so that the corrected distance information of the initial image information coincides with the acquisition distance of the gallery image in the database.
Exemplary, S131 may include:
s1311, calculating a ratio of the acquisition distance to the distance information as a target proportion.
In a specific implementation, the size of the distribution line in the initial image information is inversely proportional to the change of the distance between the distribution line and the acquisition device, i.e., the larger the distance, the smaller the imaging. The proportional magnitude of the change is in direct proportion to the change of the distance. Therefore, in the embodiment of the invention, the ratio of the imaging sizes of the objects with the same size at two distances can be known based on the ratio of the acquisition distance of the image of the gallery in the database to the distance information of the initial image information of the distribution line. That is, the image size of the distribution line at the same acquisition distance as the gallery image of the database may be determined based on the ratio of the two distances.
S1312, scaling the initial image information based on the target scale.
In the step, the ratio of the acquisition distance of the image in the gallery to the distance information of the acquired initial image information is calculated, the proportional relation between the image size in the initial image information and the image size in the image in the gallery is determined, in the step, the initial image information is zoomed according to the target proportion obtained by calculation, and the image in the initial image information is converted to be consistent with the proportion of the image in the gallery in the database.
By carrying out zoom correction on the initial image information until the initial image information is consistent with the acquisition distance of the image in the gallery in the database, the establishment difficulty of the database can be effectively reduced, and the workload of gallery image acquisition, the size of the database and the workload of subsequent matching are reduced.
And S132, matching the target image information with a preset image database to obtain a library image matched with the target image information, wherein the preset image database comprises library images of distribution lines of various line diameters and various angles which are shot in advance.
In the embodiment of the invention, the aim of matching the target image information with the preset image database is to match the image database with the same size as the line path of the distribution line. The specific identification mode is not limited in the application, as long as the gallery image with the same size as the line diameter can be obtained based on the corrected target image information matching required in the embodiment of the present invention.
For example, a gallery image with the same direction of the distribution lines in the image can be identified as an initial gallery image in an image identification mode, then a gallery image consistent with the target image information is further determined as a target gallery image according to the number and the size of pixels occupied in the line diameter direction, and the subsequent step is carried out to determine the line diameter size. Or after the initial image library images in the same direction are determined, the distribution line in the images is completely framed by using the image-taking frames in the same size, and then the image library images in the same size as the target image information are determined to be used as the matched image library images by calculating the total pixel occupation of the images of the distribution line.
In other embodiments, other forms of recognition may be used to determine the matching gallery images, and the determination is not limited in particular, as long as the gallery images meeting the requirement of determining the matching in the embodiments of the present invention can be obtained.
And S133, determining the size of the line path of the distribution line based on the image of the gallery.
In a specific implementation, the line path of the distribution line in each gallery image is determined and associated with the gallery image when the image database is established. In this step, the size of the distribution line path corresponding to the image of the gallery obtained by matching is determined.
In other embodiments of the present invention, determining the size of the line path of the distribution line based on the initial image information and the distance information may also be implemented in other manners.
Illustratively, S130 includes:
and S134, determining the line diameter pixel width of the distribution line based on the initial image information.
And the line diameter pixel width is the line diameter pixel width of the distribution line. That is, the number of pixels occupied by the image of the distribution line in the line diameter direction of the distribution line, and the size of the image.
In a particular implementation, determining the line path pixel width of the distribution line may include:
s1341, performing straight line extraction on the initial image information to obtain an object straight line.
In the embodiment of the present invention, the distribution line is in an approximately straight line state in the initial image information, and can be identified as a straight line. In specific implementation, the initial image information of the distribution line is subjected to straight line extraction, and then an object straight line including the distribution line is obtained.
During straight line extraction, Hough transformation, LSD extraction features under OpenCV and other modes can be adopted for implementation, and no limitation is made here.
And S1342, performing straight line fitting on the object straight line to obtain a target straight line.
In the foregoing step, the straight line in the initial image information is acquired to obtain the target straight line of the distribution line, and in this step, the obtained target straight line is fitted to obtain the target straight line closest to the distribution line.
S1343, making a normal of the 0 target straight line, and obtaining the pixel width of the distribution line in the normal direction as the line diameter pixel width of the distribution line.
The diameter direction of the distribution line can be determined by determining the normal of the target straight line, and the line path pixel width of the distribution line can be obtained by identifying the number of pixels in the diameter direction.
And S135, determining the size of the line diameter of the distribution line based on the distance information and the line diameter pixel width.
The size of the actual space corresponding to the size of each pixel of the initial image information at the moment can be obtained through conversion of the distance information, and then the line diameter pixel width can be converted to obtain the line diameter size of the distribution line.
In specific implementation, a plurality of initial image information and distance information can be acquired simultaneously, then a plurality of line diameters are obtained through calculation, and finally the average value of the line diameters is calculated, so that the precision of the measurement result is further improved.
