Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Method embodiment
Referring to fig. 1, a step flow diagram of an embodiment of an energy adding station queuing detection method of the present application is shown, and the method specifically may include the following steps:
step 101, detecting personnel position information in a queuing area in real time under the condition that a corner exists in the preset queuing area and/or a shielding object is detected.
The queuing area refers to a preset area for queuing personnel, such as a cash register, a demarcation queuing area in front of an airplane ticket gate. The personnel position information refers to a specific position of the queuing personnel in the queuing area, and can be specifically expressed by a cartesian coordinate system, a polar coordinate system and the like, which is not limited in the application.
The queuing area where the corner exists refers to a queuing area which is not arranged in a straight line, such as an L-shaped queuing area, a Z-shaped queuing area and the like. The shielding object may specifically be an object that shields the camera. Based on this, it can be understood that in the case that the corner exists in the queuing area and/or the shielding object is detected, the situation that the queuing situation is inaccurate in judgment is easily caused due to the confusion of the view angles, so in order to improve the accuracy of abnormal queuing detection, in the case that the corner exists in the queuing area and/or the shielding object is detected, the position information of the person in the preset queuing area can be detected in real time, so that the abnormal queuing situation can be identified in time and adjusted.
Specifically, images of the queuing area can be obtained in real time by using a plurality of cameras arranged outside, and position detection is performed on queuing personnel in the queuing area by using image recognition methods based on deep learning such as YOLOV5 and YOLOV7, for example, a target tracking algorithm based on deep learning is used for detecting the head of the queuing personnel, the position of the center point of the head of the person is taken as a specific position of the queuing personnel in the queuing area, and of course, the position of the center point of a connecting line of two feet of the queuing personnel can be taken as a specific position of the queuing personnel in the queuing area, and the position can be specifically set according to actual conditions.
As an example, referring to the flowchart of another queuing detection method for an energy adding station according to the embodiment of the present application shown in fig. 2, an image of a preset queuing area may be acquired and identified by a camera cluster including a plurality of cameras, which is deployed on the site. And further acquiring image information of each queuing personnel in the queuing area on-site queuing personnel under the condition that the queuing area is identified to be non-linear queuing or a shielding object is detected. And then detecting the head of each queuing person by using a preset deep learning model, and taking the position of the center point of the head as the specific position of the queuing person in the queuing area, thereby acquiring the person position information of the queuing person. Then, the subsequent abnormal queuing detection step can be executed based on the acquired personnel position information, so that queuing conditions respectively corresponding to each queuing area, namely abnormal queuing detection results, are obtained. In addition, taking a cashing area as an example, the training process of the deep learning model for image recognition can refer to the following process:
1. And acquiring a large amount of personnel queuing data in the cashing area, wherein the personnel queuing data comprises an arrangement area image and corresponding queuing personnel labels.
2. And preprocessing the acquired queuing data of the personnel by utilizing data enhancement technologies such as data clipping, scaling, horizontal overturning and the like.
3. Training the initial deep learning model based on the preprocessed arrangement area image and the corresponding queuing personnel labels to obtain the deep learning model for executing the step 101. And 102, performing linear regression processing based on the personnel position information to obtain at least two personnel queuing lines.
The linear regression process refers to a process of generalizing a straight line for describing a linear relationship between different points by performing regression processing on points at different positions. The specific manner of the linear regression process includes but is not limited to hough transform, least square method, ridge regression, etc., and may be specifically determined according to the actual team regression effect.
The personnel queuing line refers to a line obtained by regression processing according to the positions of queuing personnel in a single queuing area, is used for identifying the overall trend of a team formed by the queuing personnel, can be divided according to corners or shielding objects corresponding to the arrangement area, for example, a Z-shaped queuing area can be divided into an I-shaped subarea and two I-shaped subareas, and the queuing personnel in each subarea can be subjected to linear regression processing respectively, so that three personnel queuing lines are obtained. The present application also does not limit the line obtained after the regression process, and may be a line segment of a person line determined by the length of the alignment team, and the specific application may be selected according to the actual situation.
It will be appreciated that in the case where there is a corner in the queuing area and/or an occlusion is detected, inaccurate determination of the queuing situation may easily occur due to confusion of the viewing angle. Therefore, in the embodiment of the application, the personnel position information in the queuing area is utilized to carry out linear regression processing on the teams formed by the queuing personnel to obtain at least two personnel queuing lines, namely, the overall trend condition of each queuing team in the queuing area is obtained, and the accuracy of abnormal queuing detection is improved by utilizing the overall trend condition of the teams; in addition, the detection of abnormal queuing conditions is not needed manually, and the efficiency of abnormal queuing detection is improved.
Taking the queuing area A as an L-shaped queuing route as an example, the L-shaped queuing area can be substantially divided into an 'I' -shaped subarea and an 'one' -shaped subarea, each area corresponds to a personnel queuing line, and if the personnel queuing line in the 'I' -shaped area and the personnel queuing line in the 'one' -shaped area are not intersected in the queuing area, it is indicated that at least one of the two lines is too askew for the corresponding queuing line, and adjustment is needed.
Under the condition that no corner exists in the queuing area and no abnormal conditions such as shielding are detected, queuing personnel quantity information of different queuing areas can be directly acquired through the camera, and the queuing personnel quantity of each queuing area is adjusted according to the queuing personnel quantity of each queuing area, so that the execution efficiency of work is improved while the site order is ensured. Based on this. The working efficiency of the staff can also be judged according to the number of the staff flowing in the queuing area, and the application is not limited to the working efficiency.
And step 103, if the relative position relation of the at least two personnel queuing lines does not meet the preset position condition, determining that the queuing situation in the queuing area is abnormal queuing.
The preset position condition is a condition for detecting whether the personnel queuing lines in the same queuing area, namely the queuing teams are orderly, for example, if a camera shielding object exists, the two personnel queuing lines in front and behind the shielding object are parallel and can be determined to be normal queuing conditions on the same line, if the overall trend deviation of the two lines is too large, the situation that the queuing teams in the queuing area are too disordered is indicated, and the situation belongs to abnormal queuing; under the condition that a corner exists in the queuing area, whether the abnormal queuing exists or not can be judged according to the intersecting condition of queuing straight lines of different people or queuing line segments of the people.
When the relative position relation of at least two personnel queuing lines does not meet the preset position condition, the queuing situation in the queuing area can be determined to be abnormal queuing, then early warning is carried out, the order of the queuing area is timely adjusted, and the problem that the operation efficiency of field work is reduced due to disorder of the field order is avoided.
And 104, if the relative position relation of the at least two personnel queuing lines meets a preset position condition, determining that the queuing situation in the queuing area is normal queuing.
And when the relative position relation of the at least two personnel queuing lines meets the preset position condition, the situation that the queues in the queuing area are not excessively disordered is indicated, and the queuing situation in the queuing area can be determined to be normal queuing. Under the condition of normal queuing, the method is beneficial to improving the execution efficiency of subsequent work such as personnel quantity detection, personnel dredging and the like.
In summary, the present application provides a queuing detection method for an energy adding station, which detects personnel position information in a queuing area in real time through the condition that a corner exists in a preset queuing area and/or a shielding object is detected; performing linear regression processing based on the personnel position information to obtain at least two personnel queuing lines; if the relative position relation of the at least two personnel queuing lines does not meet the preset position condition, determining that the queuing situation in the queuing area is abnormal queuing; and if the relative position relation of the queuing lines of the at least two persons meets a preset position condition, determining that the queuing condition in the queuing area is normal queuing. By the method, at least two personnel queuing lines in the queuing area can be obtained in real time by utilizing the linear regression processing, namely, the overall trend situation of each queuing team in the queuing area can be obtained quickly, and the accuracy rate of abnormal queuing detection can be improved by utilizing the overall trend situation of the team; in addition, the detection of abnormal queuing conditions is not needed manually, and the efficiency of abnormal queuing detection is improved.
Optionally, in step 102, performing a linear regression process based on the personnel location information to obtain at least two personnel queuing lines, including:
s11, dividing the queuing area into at least two sub-areas according to the position of the corner and/or the position of the shielding object;
and step S12, carrying out Hough transformation based on the personnel position information in the subareas to obtain at least two personnel queuing lines, wherein one subarea corresponds to one personnel queuing line. Among them, hough transform is a feature extraction technique in image processing, and detects an object having a specific shape by a voting algorithm. When the straight line detection is carried out, the object to be detected is transferred to the Hough space, and an accumulator is utilized to find an optimal solution, and the optimal solution is the required straight line. In the process of converting the object into the hough space, different expression modes can be selected according to different detection objects, for example, a coordinate expression mode based on a cartesian space coordinate system, a polar coordinate expression mode and the like, and the selection can be specifically performed according to actual conditions, which is not limited in the application.
In order to reduce the interference of the situations such as corners and shielding objects on queuing detection in the queuing area, the queuing area can be divided into at least two sub-areas according to the positions of the corners and/or the positions of the shielding objects, and Hough transformation based on queuing personnel in each sub-area is performed.
Optionally, the personnel location information includes an ordinate and an abscissa of a location where the queuing personnel are located; step S12, performing hough transform based on the personnel location information in the sub-area to obtain at least two personnel queuing lines, may include:
step S21, mapping a first polar coordinate parameter formula corresponding to personnel position information of each sub-area into a second polar coordinate parameter formula in a Hough space, wherein the second polar coordinate parameter formula comprises a distance parameter, an angle parameter, and an abscissa and an ordinate of queuing personnel;
step S22, traversing a plurality of preset angle parameters, inputting the preset angle parameters, the ordinate and the abscissa of the position of the queuing personnel in the subarea into the second polar coordinate parameter formula, and calculating to obtain a corresponding distance parameter result;
step S23, counting the occurrence times of different distance parameter results under the same preset angle parameter;
step S24, determining a distance parameter result under the angle parameter with the occurrence frequency meeting a preset condition as a target distance parameter, and determining an angle parameter corresponding to the target distance parameter as a target angle parameter;
And S25, determining a target polar coordinate formula corresponding to the second polar coordinate parameter formula based on the target distance parameter and the target angle parameter, and determining a straight line corresponding to the target polar coordinate formula as a personnel queuing straight line.
In order to express the position information of the queuing personnel in the queuing area, the relative position of each queuing personnel can be measured by using a preset Cartesian coordinate system. Wherein, (x) i ，y i ) The location of the i-th queuing personnel in the current queuing sub-area may be indicated.
It will be appreciated that in a Cartesian coordinate system, a straight line may be defined by two points (x 1 ，y 1 ) And (x) 2 ，y 2 ) And (5) uniquely determining. Assuming that the straight line equation of the person queuing straight line corresponding to the current sub-region is y=ax+b, the expression written as (a, b) is converted as follows:
the space expressed by the formula (1) obtained after conversion is the Hough space, namely, one straight line in a Cartesian coordinate system corresponds to one point (a, b) in the Hough space, and the straight line can be uniquely determined by the point (a, b).
Considering the possible "a value does not exist", the linear equation in the cartesian coordinate system may be converted into a polar coordinate equation for expression, where the polar coordinate equation may be expressed as the following equation, the first polar coordinate parameter equation:
The second pole coordinate parameter formula can be obtained after simple transformation of the formula (2):
x cosθ+y sinθ＝ρ， (3)
where ρ is the distance from the point to the origin, θ is the angle between the normal to the point and the x-axis, and x and y represent the abscissa and ordinate of the queuing personnel's location in the queuing area, respectively.
In order to calculate (ρ, θ) which corresponds to the queuing line of people in the current sub-area, each preset angle parameter can be traversed, and the current angle parameter and each (x i ，y i ) Inputting into the above formula (3) to obtain the jth angle parameter θ j The ith queuing personnel position point (x i ，y i ) Corresponding distance parameter ρ (i, j). Then counting the occurrence times of rho (i, j) under the same angle parameter, and determining the rho (i, j) meeting the preset condition as a target distance parameter rho max The target distance parameter ρ is calculated max The corresponding angle parameter is determined as the target angle parameter theta max . Wherein the preset conditions include, but are not limited to, the number of occurrences being greater than a preset threshold, the ranking of the number of occurrences conforming to a preset ranking, etc.
Extreme point (ρ) max ，θ max ) Converting back to a cartesian coordinate system. At theta max If it is not 0 or pi, the following formula is referred to:
parameters k and b in the parameter equation of the personnel queuing line of the current subarea can be obtained, and are substituted into the formula (1), so that the personnel queuing line of the current subarea is obtained as follows:
y＝kx+b＝-(cos(θ max )/sin(θ max ))x+ρ max /sin(θ max )， (5)
After Hough transformation is carried out on the queuing personnel positions in each sub-area, personnel queuing straight lines corresponding to each sub-area are obtained.
Assuming that a straight line exists in an 8×8 plane pixel with the maximum number of occurrences as the preset condition, the coordinates of each pixel point are (8, 1), (7, 2), (6, 3), (5, 4), (4, 5), (3, 6), (2, 7), (1, 8), and ρ is calculated when θ is 0 °, 45 °, 90 °, 135 °, 180 ° from the upper left corner (1, 8) pixel point, and the coordinates and θ are substituted into the above formula (3), so that different ρ values corresponding to different coordinate points and different θ can be obtained, for example, ρ corresponding to (1, 8) is 1,8、/>-1, and respectively recording a ticket for the 5 values, similarly calculating the rho values corresponding to the pixel points (3, 6) when theta is 0 DEG, 45 DEG, 90 DEG, 135 DEG and 180 DEG, and respectively recording a ticket for the calculated 5 rho values. By the same token, when traversing the entire 8×8 pixel space and each θ, "θ=45°," θ ->"record 5 sheets, p value corresponding to other angle parameter θThe number of tickets is less than 5 tickets, so the polar coordinate equation of the straight line in the 8×8 pixel coordinates is obtained asThat is, the equation expression of the people queuing line is: x+y=9. The preset angle parameter may be adjusted according to the actual situation, which is not limited in the present application.
In the straight line regression mode based on the Hough transform of the polar coordinates, the coordinate points corresponding to each queuing personnel are independently processed, so that even if part of contents are blocked, straight line regression can be performed through voting processing, the problem of blocking objects can be well solved, and the recognition accuracy of the straight lines corresponding to the arrangement teams is improved.
Optionally, step S11 divides the queuing area into at least two sub-areas according to the position of the corner and/or the position of the obstruction, including:
step S31, if a corner exists in the queuing area, dividing the queuing area into at least two sub-areas by taking the position of the corner as a boundary;
and step S32, if the existence of the shielding object in the queuing area is detected, dividing the queuing area into at least two sub-areas by taking the shielding object as a boundary.
In the case that a corner exists in the queuing area, the queuing area can be divided into at least two sub-areas by taking the position of the corner as a boundary. For example, the Z-shaped queuing area may be divided into one "|" type sub-area and two "one" type sub-areas.
Under the condition that the shielding object is detected, the shielding object is taken as a boundary, and the queuing area is divided into at least two sub-areas according to the position of the shielding object. For example, when there is one obstruction in the rectangular queuing area a, the area before and after the obstruction may be divided into two sub-areas with the long side of a as a reference.
In the case where there is a corner in the queuing area and a blocking object is detected, the queuing area may be divided into at least three sub-areas with the blocking object and the corner as boundaries, respectively. For example, the current queuing area B is an "L" type area, and at the same time, the camera detects that the blocking object is present to block the lens when detecting the "one" type sub-area, so the "one" type sub-area can be further divided into two sub-areas according to the position of the blocking object, that is, the "L" type area where the blocking object is detected is divided into three sub-areas.
Optionally, the method further comprises:
step S41, if the queuing situation in the queuing area is normal queuing, the number of workers in the working area and the number of queuing workers in the queuing area are obtained;
step S42, if the number of staff is zero and the number of queuing staff is not zero, modifying the queuing situation into abnormal queuing and sending a reminding message;
and step S43, if the number of staff is not zero and the number of queuing staff in each queuing area does not meet the preset number of staff condition, modifying the queuing situation into abnormal queuing and sending a reminding message.
The queuing situation of normal queuing includes, but is not limited to, a situation that no corner exists in a queuing area and no shielding is detected, a situation that at least two straight lines meet preset conditions as shown in fig. 1, and the like.
In order to realize reasonable scheduling of queuing personnel in different queuing areas and improve the on-site operation efficiency, secondary queuing condition detection and early warning can be performed according to the number of workers and the number of queuing personnel in different queuing areas. The preset personnel number conditions include, but are not limited to, differences of queuing people in each queuing area, numbers of people in a single queuing area not exceeding a preset value, and the like, and the preset personnel number conditions can be continuously adjusted according to actual conditions, so that the method is not limited. Specifically, under the condition that the number of workers corresponding to the queuing area is zero, the queuing area is indicated to provide no service, and the queuing area belongs to abnormal queuing; and under the condition that the number of workers corresponding to the queuing area is not zero, the operation efficiency of different queuing areas is balanced, and if the number of the queuing personnel in each queuing area does not meet the preset personnel number condition, a prompt message is required to be sent out to adjust the number of the queuing personnel in the queuing area.
Taking a bank cashing area as an example, referring to a flowchart of an energy adding station queuing detection method based on the number of people in a queue provided in the embodiment of the application shown in fig. 3, where Y represents yes and N represents no. Under the condition that the queuing situation in the queuing area is normal queuing, detecting the number of workers, if no workers and queuing workers in a certain queuing area are detected, outputting abnormal queuing, and sending a prompt message to adjust the queuing workers in the area to other areas or arrange the workers in the area; if the presence of staff and queuing staff is detected, the maximum value and the minimum value of the number of queuing staff in a plurality of queuing queues, namely the maximum value and the minimum value of the queues in the figure 3, are calculated, the difference value of the maximum value and the minimum value is calculated, and the difference value is compared with a preset threshold value of the number of abnormal queuing people. If the difference value is smaller than or equal to a preset threshold value of the number of people, the queuing is normal, if the difference value is larger than the threshold value, abnormal queuing is performed, early warning is performed, the order of queuing areas is adjusted in time, and the problem that the operation efficiency of field work is reduced due to disorder of the field order is avoided.
In addition, the staff efficiency can be counted according to the number of the queuing staff tracked. The deep learning algorithm is used for tracking the head of the queuing personnel, and the efficiency of the staff is judged according to the number of the queuing personnel completed in a certain time, so that the management strategy adjustment and personnel optimization are convenient.
Optionally, the preset personnel number condition includes: the difference between the queuing area with the largest queuing personnel and the queuing area with the smallest queuing personnel is larger than a preset threshold value.
The preset threshold value can be adjusted according to actual conditions, and the application is not limited to the preset threshold value. Optionally, the preset position condition includes any one of the at least two person queuing lines being parallel to each other, the at least two person queuing lines belonging to the same line, and an intersection point of the at least two person queuing lines being located in the queuing area.
Aiming at the position conditions that the at least two straight lines are parallel to each other and the at least two straight lines belong to the same straight line, the fact that the individual difference of queuing personnel and errors possibly exist in the straight line regression processing are considered, so that in the embodiment of the application, the same straight line and the parallel condition can be expanded into that an obtuse included angle between any adjacent straight lines is larger than or equal to a preset angle in the at least two straight lines, wherein the preset angle can be adjusted according to actual conditions, and the application does not limit the method.
In addition, in order to further improve the accuracy of abnormal queuing detection, preset position conditions can be set specifically for the situations that different corners exist in the queuing area, shielding objects are detected and the like. For example, in the case where a camera shielding object is present, the preset position condition is set to any one of "the at least two straight lines are parallel to each other", "the at least two straight lines belong to the same straight line", and "an obtuse included angle between any adjacent straight lines is greater than or equal to a preset angle" in the at least two straight lines; in case there is a corner in the queuing area, the preset position condition may be set to "the intersection of the at least two straight lines is located within the queuing area". Based on the method, interference of the conditions such as corners and shielding objects on linear regression processing is further reduced, and the accuracy of abnormal queuing detection is improved.
