Detailed Description
The following describes in detail the embodiments of the present application with reference to the drawings attached hereto.
In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, interfaces, techniques, etc. in order to provide a thorough understanding of the present application.
The terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. Further, the term "plurality" herein means two or more than two.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a project operation detection method according to the present application. Specifically, the method may include the steps of:
step S11: and acquiring an original image shot by the camera device on the operation site, wherein the original image comprises a preset detection area.
In this embodiment, the image pickup device may include a monitoring camera such as a ball machine or a card machine, and this embodiment is not limited specifically herein. In practical application, a plurality of areas needing to be detected may exist in a working site, and in this case, in order to enable the image pickup device to automatically shoot a plurality of areas needing to be detected in the working site, the pose parameters set by a user on the image pickup device can be obtained, so that a plurality of preset bits are set for the image pickup device, the image pickup device shoots the working site at the plurality of preset bits, and the whole working site is covered. Use electric power to overhaul as the example, camera device can set up the northeast corner at electric power computer lab, and during the detection, need shoot the southeast region of electric power computer lab, northwest region, southwest region, consequently, can set up three preset for camera device shoots towards southeast region, southwest region, the northwest region of electric power computer lab respectively in engineering operation testing process, thereby can cover the operation scene.
In this embodiment, the preset detection area is an area that needs to be detected by engineering work and is preset by a user, specifically, the preset detection area may be set as a rectangular area, and when the user sets the area, the coordinates of the rectangular area in the image may be set. In a specific implementation scenario, when the image pickup device is provided with a plurality of preset bits, the preset detection area may also be provided in plurality and correspond to the preset bits one to one. Still take electric power to overhaul as an example, be equipped with above-mentioned three presetting bit respectively when camera device to make camera device in engineering operation testing process, when shooting towards electric power computer lab southeast region, southwest region, northwest region respectively, can set up electrified regional to above-mentioned three presetting bit respectively, thereby can be based on the position relation between the target object that follow-up detection obtained and the electrified region that sets up in advance, confirm whether electric power overhauls the scene and accords with the operation standard.
In addition, similar settings can be performed in other engineering applications such as building engineering, communication engineering, etc., and this embodiment is not illustrated here.
Step S12: and carrying out target detection on the original image to obtain a target area corresponding to the target object in the original image.
In this embodiment, the target object is used for realizing warning, and taking electric power overhaul as an example, the target object may be a red cloth mantle. In other engineering works, the target object can also be other warning objects, for example, in a building project, the target object can also be a warning line and the like; in the communication engineering, the target object may also be a warning slogan, and the like, which is not illustrated herein.
In this embodiment, the specific target detection mode may be a detection mode based on a neural network. For example, a training image marked with a target object is used to train a preset neural network to obtain a trained preset neural network, and then the trained preset neural network is used to detect an original image to obtain a target area corresponding to the target object. Or, the specific method of target detection may also be a detection method based on traditional image analysis, for example, the color features of each pixel point in the original image are analyzed to obtain pixel points similar to the color features of the target object, then the pixel points are subjected to noise reduction and other processing, and finally the minimum circumscribed rectangle of the pixel points subjected to the noise reduction and other processing is taken as the target region corresponding to the target object. The embodiment is not particularly limited herein.
Step S13: and determining whether the operation site meets the operation specification or not based on the position relation between the preset detection area and the target area.
In an implementation scenario, when an overlap area exists between the preset detection area and the target area, it can be considered that a target object is arranged in the preset detection area, and it is determined that the operation site meets the operation specification, otherwise, it is determined that the operation site does not meet the operation specification.
In another implementation scenario, when the preset detection area completely includes the target area, it is determined that the target object is disposed in the preset detection area, and it is determined that the operation site meets the operation specification, otherwise, it is determined that the operation site does not meet the operation specification.
In another implementation scenario, when an intersection ratio (IoU) between a preset detection area and a target area is greater than a preset intersection ratio threshold (e.g., 0.5), it is determined that a target object is disposed in the preset detection area, and if not, it is determined that the operation site meets the operation specification.
In a specific implementation scenario, when it is determined that the operation site does not meet the operation specification, preset alarm information may be output. In addition, when the work site is determined to meet the work specification, preset safety information may be output, or no information may be output. The preset alarm information and the preset safety information may include, but are not limited to: text, sound, image, etc., and the embodiment is not illustrated here. In addition, when the target detection is carried out on the original image and the target area corresponding to the target object is not detected, the preset alarm information can be directly output, so that the warning that the operation site does not conform to the operation specification is realized.
According to the scheme, the original image shot by the camera device on the operation site is obtained, the original image comprises the preset detection area, the target detection is carried out on the original image, the target area corresponding to the target object used for realizing warning in the original image is obtained, and whether the operation site meets the operation specification or not is determined based on the position relation between the preset detection area and the target area, so that whether the operation site meets the operation specification or not can be detected based on the original image shot by the camera device on the operation site, the operation site does not need to be checked manually, the detection efficiency can be improved, the probability of omission is reduced, and the detection quality of engineering operation can be improved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an embodiment of step S12 in fig. 1. The method specifically comprises the following steps:
step S121: and performing threshold segmentation on the original image by using a preset threshold related to the color characteristics of the target object to obtain an image to be detected.
In a specific implementation scenario, taking electric power overhaul as an example, if the target object is a red cloth mantle, a preset threshold related to the color characteristics of the red cloth mantle can be adopted to perform threshold segmentation on the original image, so as to obtain an image to be detected. In other application scenarios, the same can be analogized, and the embodiment is not illustrated here.
In addition, since the RGB (Red Green Blue ) color space is very different from human eyes, in order to make the definition of the color distance conform to human visual characteristics, the present embodiment may further map the color space of the original image to an HSV (Hue, Saturation, and brightness) color space before performing the threshold segmentation. In a specific implementation scenario, when the color space of the original image is an RGB color space, the color space of the original image may be mapped to an HSV color space by the following formula:
in the above formula, (R, G, B) represents an R channel pixel value, a G channel pixel value, and a B channel pixel value of a certain pixel point in the original image.
In addition, the (H, S, V) may be mapped to the interval of 0 to 255, which is not described herein again. In a specific implementation scenario, the preset threshold may include: in other implementation scenarios, the value may be other values, and the embodiment is not limited specifically herein. By utilizing the preset threshold, whether each pixel point in the original image mapped to the HSV color space meets the following conditions can be sequentially judged: whether the H channel pixel value is within a preset H channel threshold interval, whether the S channel pixel value is within a preset S channel threshold interval, and whether the V channel pixel value is within a preset V channel threshold interval, if yes, setting the pixel value of the corresponding pixel point in the image to be detected as a first pixel value (for example, 255), and otherwise, setting the pixel value of the corresponding pixel point in the image to be detected as a second pixel value (for example, 0). Specifically, the pixel value of a pixel point related to the color feature of the target object in the image to be detected is a first pixel value, and the pixel value of a pixel point unrelated to the color feature of the target object is a second pixel value.
Step S122: and counting the sum of the pixel values of all the pixel points in the upper left area of each pixel point in the image to be detected, and taking the sum as the pixel value of the corresponding pixel point in the first integral image corresponding to the image to be detected.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating an embodiment of an obtaining process of the first integral map in fig. 2. As shown in FIG. 3, P1Is the image to be detected, P1(i, j) is the pixel value of the pixel point positioned in the ith row and the jth column of the image to be detected, Q1Is a first integral image, Q1And (i, j) is the pixel value of the pixel point positioned on the ith row and the jth column of the first integral image. The first integral image may be obtained based on the image to be detected by:
step S123: and performing morphological processing on the image to be detected by using a preset structural element and the first integral image to obtain a target area corresponding to the target object in the original image.
The preset structural element in this embodiment is a two-dimensional matrix, the value of the matrix element is 1, and the size of the matrix element may be 15 × 15, 13 × 13, 11 × 11, or 9 × 9, which is not limited in this embodiment.
In one implementation scenario, the image to be processed may be morphologically processed directly using the preset structural elements. For example, when the preset structural element is used for performing corrosion morphological processing on an image to be processed, a target pixel point with a pixel value of a first pixel value in the image to be processed can be traversed by using an atom (namely, a central point) of the preset structural element, when the pixel values of other pixel points in a size region of the preset structural element are the same as the pixel values of the target pixel point, namely the pixel values of the other pixel points are the first pixel values, the pixel value of the target pixel point is reserved, and otherwise, the pixel value of the target pixel point is set to be a second pixel value. Referring to fig. 4 in combination, fig. 4 is a schematic diagram of an embodiment of morphological processing in fig. 2, specifically, fig. 4 is a schematic diagram of an embodiment of etching morphological processing by using a preset structural element, as shown in fig. 4, the size of the preset structural element is k × k, the size of the image to be detected is w × h, and the image to be detected after the etching morphological processing is shown in fig. 4, where the pixel value is a target pixel point of a first pixel value, as shown in fig. 4, the burr in the image to be processed can be eliminated after the etching morphological processing. However, the algorithm complexity for performing the erosion morphology processing on the image to be processed by directly adopting the preset structural elements is O (w × h × k), which is high in complexity and high in processing load and resource overhead.
In another implementation scenario, in order to reduce algorithm complexity, processing load, and resource overhead, the first integral image may be used to perform morphological processing on the image to be processed. Specifically, referring to fig. 5 in combination, fig. 5 is a schematic flowchart of an embodiment of step S123 in fig. 2, which may specifically include:
step S1231: and carrying out corrosion morphological processing on the image to be detected by utilizing a preset structural element and the first integral image to obtain a first processed image.
Specifically, a first target pixel point with a pixel value of a first pixel value in an image to be detected can be determined, a second target pixel point corresponding to the first target pixel point in a first integral image is determined, a third target pixel point in the first integral image is determined based on the second target pixel point and the size of a preset element structure, then the pixel value of the third target pixel point is utilized to calculate the sum of the pixel values of all pixel points in the size range around the first target pixel point, if the quotient of the calculated sum of the pixel values and the size is the first pixel value, the first target pixel point can be considered to be not a burr/noise point, the pixel value of the first target pixel point is kept as the first pixel value, if the quotient of the sum of the pixel values and the size is not the first pixel value, the first target pixel point can be considered to be the burr/noise point, the pixel value of the first target pixel point is reset to the second pixel value.
In one embodiment, with continued reference to FIG. 3, the image P to be detected is shown in FIG. 31In the pixel (i, j) is a first target pixel, and correspondingly, a first integral image Q1In the method, the pixel point (i, j) is a second target pixel point corresponding to the first target pixel point, the thick black frame area is a size (k × k) area of a preset structural element, and in order to calculate the image P to be detected1The sum of pixel values of pixels in the size region of the medium-sized preset structural element can use the first integral image Q1The calculation is performed, and during the calculation, the first integral image Q can be determined by using the size of the preset structural element1The third target pixel point in (1) may be, first, the first integral image Q1The pixel point at the lower right corner of the size area of the preset structural element
Determining a first third target pixel point with a pixel value of
Representing pixel points
The sum of the pixel values of all pixel points in the upper left corner area is determined, and then three third target pixel points are determined
Therefore, the sum of the pixel values of all pixels within the size (k × k) around the first target pixel (i, j) can be expressed as:
after calculating the sum S of the pixel values of all pixels within the range of the size (k × k) around the first target pixel (i, j), the quotient (i.e. the sum S of the pixel values and the size (k × k)) can be further calculated
) If the quotient is the first pixel value, the image P to be detected is indicated1The pixel values of all the pixels in the size (k × k) range of the first target pixel (i, j) are the first pixel values, the first target pixel (i, j) can be considered as not a burr/noise point, and at the moment, the image P to be detected can be kept1If not, the first target pixel point (i, j) is a burr/noise point, and the image P to be detected is processed1And resetting the pixel value of the first target pixel point (i, j) to be the second pixel value.
By using the integral graph to perform the corrosion morphology processing, the algorithm complexity can be reduced to O (w × h), and the algorithm complexity is remarkably reduced.
Step S1232: and counting the sum of the pixel values of all the pixels in the upper left region of each pixel in the first processed image, and taking the sum as the pixel value of the corresponding pixel in the second integral image corresponding to the first processed image.
In an implementation scenario, after the image to be processed is subjected to erosion morphological processing, the dilation morphological processing may be further continued, and similarly to the above steps, the sum of the pixel values of all the pixel points in the upper left region of each pixel point in the first processed image may be counted as the pixel value of the corresponding pixel point in the second integral image corresponding to the first processed image. The related steps in this embodiment may be referred to, and are not described herein again.
Step S1233: and performing expansion morphological processing on the first processed image by using a preset structural element and the second integral image to obtain a second processed image.
Specifically, each pixel point in the first processed image may be sequentially used as a fourth target pixel point, a fifth target pixel point corresponding to the fourth target pixel point in the second integral image is determined, a sixth target pixel point in the second integral image is determined based on the size of the fifth target pixel point and a preset structural element, the sum of pixel values of all pixel points in a size range around the fourth target pixel point is calculated by using the pixel value of the sixth target pixel point, if the quotient of the sum of the pixel values and the size is the second pixel value, the pixel value of the fourth target pixel point is set as the second pixel value, and if the quotient of the sum of the pixel values and the size is not the second pixel value, the pixel value of the fourth target pixel point is set as the first pixel value. The specific manner of determining the sixth target pixel point in the second integral image based on the size of the fifth target pixel point and the preset structural element, and calculating the sum of the pixel values of all pixel points within the size range around the fourth target pixel point by using the pixel value of the sixth target pixel point may refer to step S1231 in this embodiment, which is not described herein again. Different from the erosion morphological processing, the purpose of the dilation morphological processing is to expand the edge and fill the void, so as long as a pixel with a first pixel value exists in the size range of the preset structural element, that is, as long as the quotient of the sum of the pixel values and the size is not the second pixel value, the pixel value of the fourth target pixel is set to be the first pixel value, otherwise, if the pixel with the first pixel value exists in the size range of the preset structural element, that is, if the quotient of the sum of the pixel values and the size is the second pixel value, the pixel value of the fourth target pixel is set to be the second pixel value, and the edge can be significantly expanded and the void can be filled in the edge in this way.
Step S1234: and determining the pixel value of each pixel point in the second processed image as a target connected domain of the first pixel value.
After the image to be processed is subjected to corrosion morphological processing and expansion morphological processing, a second processed image is obtained, at the moment, if the pixel value of a certain pixel point and the pixel value of a neighborhood pixel point in the second processed image are both the first pixel value, the pixel point and the neighborhood pixel point are divided into the same connected domain, all the pixel points in the second processed image are traversed, and at least one target connected domain can be obtained.
Step S1235: and acquiring the minimum circumscribed rectangle of the target connected domain as a target area.
And taking the minimum bounding rectangle of the target connected domain as a target area.
Different from the embodiment, the method includes the steps of performing threshold segmentation on an original image by using a preset threshold related to color features of a target object to obtain an image to be detected, counting the sum of pixel values of all pixel points in an upper left region of each pixel point in the image to be detected, and using the sum as the pixel value of a corresponding pixel point in a first integral image corresponding to the image to be detected, so that morphological processing is performed on the image to be detected by using a preset structural element and the first integral image to obtain a target region corresponding to the target object in the original image, the algorithm complexity can be reduced, the processing time can be shortened, the target detection speed is accelerated, real-time detection of whether engineering operation is standard is facilitated, and timely alarming is performed when the engineering operation is not standard.
