Description

Technical Field

[0001] The present disclosure relates to the technical field of worker tracking, and specifically, to a method and related device for dynamically tracking high-risk workers. Background Art

[0002] With the continuous development of the industrial field, high-altitude work has become one of the common high-risk work forms in multiple industries such as power, construction, and communication. These operations usually require workers to climb to relatively high positions to perform equipment installation, maintenance, or repair work. The working environment is complex and dangerous. Once an accident occurs to a worker, it may lead to serious safety accidents. Therefore, real-time monitoring and management of high-altitude work are crucial.

[0003] In traditional monitoring systems, mobile video terminals (such as ball cameras and pan-tilt cameras) are widely used for safety monitoring in high-risk work areas. These video terminals usually achieve omnidirectional view adjustment of the camera through a pan-tilt control system. The back-end safety supervisors manually operate the pan-tilt according to the monitoring screen to pay attention to the real-time status of the workers. However, this manual control method has obvious limitations: (1) slow response speed. When a worker makes a rapid movement or suddenly encounters a dangerous situation during the high-altitude climbing process, the back-end operator may not be able to adjust the camera view in time, thus missing key monitoring screens; (2) strong dependence: the entire monitoring process completely depends on the operation ability and attention of the back-end personnel, which not only increases the labor cost but also easily leads to safety hazards due to operation errors or negligence; (3) incomplete coverage: due to the limited view of the video terminal, it is difficult to cover the entire work area in a short time through manual operation, especially in a complex environment, it is easy to have monitoring blind spots, increasing the risk.

[0004] The above problems make it difficult for traditional monitoring means to provide effective real-time monitoring guarantee in the face of high-risk scenarios such as high-altitude work and cannot fully meet the needs of modern industrial safety management. Therefore, there is an urgent need for a more intelligent and efficient monitoring solution to solve the limitations of traditional manual control and enhance the real-time monitoring ability of high-risk work.

[0039] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present disclosure.

[0040] The first embodiment of the present disclosure provides a method for dynamically tracking high-risk operation personnel. This embodiment aims to solve the problem that the pan-tilt control of traditional mobile video terminals completely depends on the background safety supervisors. Especially when monitoring high-risk operation personnel such as those climbing heights, it is difficult to timely pay attention to the safety status of these personnel due to manual operation. This embodiment can automatically identify the personnel climbing heights and dynamically track them through technologies such as intelligent recognition at the front end, and realize real-time attention to the safety measure hanging status of high-risk operation personnel, thereby improving the operation safety.

[0041] As Figure 1As shown, the dynamic tracking method for high-risk operation personnel includes:

[0042] S101, obtaining the first position of the climbing carrier and the second position of the person to be measured.

[0043] In this step, the first position of the climbing carrier and the second position of the person to be measured are obtained. The climbing carrier here includes carriers such as bamboo ladders, utility poles, scaffolds, and iron towers that can enable the person to be measured to climb. The first position here can be the position of the bottom center point of the climbing carrier.

[0044] Specifically, in this step, the first position of the climbing carrier and the second position of the person to be measured can be obtained in various ways. For example, it can be achieved by setting GPS devices, position sensors, or height sensors on the climbing carrier and the person to be measured.

[0045] Of course, it is also possible to identify the climbing carrier and the person to be measured in the image data captured by, for example, a camera device, and obtain the first position of the climbing carrier and the second position of the person to be measured based on the recognition algorithm in the image data.

[0046] For this purpose, first define the world coordinate system (X, Y, Z) and the camera device coordinate system (x, y, z). Among them, the world coordinate system is a fixed coordinate system, and the camera device coordinate system changes with the movement of the camera device. The first position and the second position here are determined based on the world coordinate system.

[0047] In order to identify the climbing carrier and its first position in the image data captured by the camera device, for example, a climbing carrier recognition model for the climbing carrier can be pre-trained. The training samples of the climbing carrier recognition model here include historical image data with pre-labeled climbing carriers. These historical image data include image data with pre-labeled types, shapes, materials, and common working environments of the climbing carriers.

[0048] Specifically, the climbing carrier recognition model here can be a deep learning model, and the recognition accuracy of the model is continuously optimized through a feedback correction mechanism to ensure that information such as the type, shape, and position of the edge points of the climbing carrier can be recognized, so as to obtain the first position of the climbing carrier. In addition, a human body recognition model can also be used to identify the person to be measured and its position information in the image data captured by the camera device, so as to obtain the second position of the person to be measured.

[0049] In a specific embodiment, the position coordinates Pv=(Xv, Yv, Zv) of the first position of the bottom center point of the climbing carrier and the position coordinates Pp=(Xp, Yp, Zp) of the second position of the person to be measured are obtained by identifying and acquiring through the above-mentioned climbing carrier identification model and human body identification model, and the above position coordinates are all defined in the world coordinate system.

[0050] In addition, the height h of the climbing carrier can also be obtained by, for example, image recognition. v , so that the position coordinates of the top center point of the climbing carrier can be expressed as:

[0051] P vtop =(X v ,Y v ,Z v +h v ).

[0052] S102. Determine the relative position between the climbing carrier and the target to be measured based on the first position and the second position, and determine whether the person to be measured is a climbing person based on the relative position.

[0053] After obtaining the first position of the climbing carrier and the second position of the person to be measured through the above step S101, in this step, the relative position between the climbing carrier and the target to be measured is determined based on the first position and the second position, and whether the person to be measured is a climbing person is determined based on the relative position. The purpose of this step is to determine whether the target to be measured is a climbing person based on the relative position between the climbing carrier and the target to be measured.

[0054] In one embodiment, it is determined whether the person to be measured is a climbing person by judging whether the second position of the person to be measured is within a predetermined range of the top plane of the climbing carrier and further judging whether the person to be measured is within a predetermined range above the top of the climbing carrier.

[0055] Specifically, the straight-line distance between the position of the person to be measured and the position of the top center point of the climbing carrier is determined as:

[0056]

[0057] where, if d xy ≤r v , it is determined that the horizontal position of the person to be measured is within the predetermined range of the top plane of the climbing carrier, where r v is the horizontal distance threshold.

[0058] Further, it is determined whether the position of the person to be measured is within a predetermined range above the top of the elevated carrier in the vertical direction. Thus, if Z p >Z v +h v , and the horizontal position meets the condition d xy ≤r v , then it is determined that the position of the person to be measured is within the predetermined range above the top of the elevated carrier, that is, the elevated person. Wherein, Z p represents the vertical position of the person to be measured, Z v represents the height of the top of the elevated carrier, and h v represents the height of the elevated carrier.

[0059] Further, it is also possible to determine whether the person to be measured is adjacent to the elevated carrier by judging the distance threshold, that is, whether it is within the adjacent range of the top of the elevated carrier.

[0060] Specifically, the horizontal distance difference between the straight-line distance and the horizontal distance threshold is obtained, that is, d xysurface =d xy -r v . By means of this difference, it is judged whether the person to be measured is within the adjacent range of the top of the elevated carrier. If d xysurface ≤d threshold , where d threshold is a predefined adjacent threshold, it indicates that the person to be measured is adjacent to the elevated carrier on the horizontal plane. In addition, it is further judged whether the vertical position of the person to be measured is within the height range of the elevated carrier, that is, Z v ≤Z p ≤Z v +h v . If this condition is met and the horizontal distance difference d xysurface is less than the adjacent threshold d threshold , then it can be considered that the person to be measured and the elevated carrier are within the adjacent range, and the person to be measured is determined to be the elevated person.

[0061] Based on the above, according to the relative position between the person to be measured and the elevated carrier, when it is determined that the person to be measured is above the elevated carrier or adjacent to the elevated carrier, it is determined that the person to be measured is performing elevated work and is the elevated person.

[0062] S103, adjust the imaging device so that the elevated person is located at a predetermined position in the imaging screen.

[0063] After determining the relative position between the elevated working carrier and the target to be measured based on the first position and the second position through the above step S102 and determining whether the person to be measured is an elevated worker based on the relative position, in this step, the imaging device is controlled to move so that the elevated worker is located at a predetermined position in the imaging frame. The predetermined position here can be the central area of the imaging frame.

[0064] Among them, in order to keep the elevated worker always in the central area of the imaging frame, the viewing angle of the imaging device should be adjusted to the position of the elevated worker. For this purpose, the pitch angle θ tilt (for example, the up and down tilt angle of the imaging device relative to the horizontal plane) and the horizontal rotation angle θ pan (for example, the rotation angle of the imaging device relative to a fixed direction) should satisfy the following formula:

[0065]

[0066] Since the horizontal rotation angle is the arctangent of the ratio of the left - right position difference (Y p -Y v ) of the target point (i.e., the elevated worker) relative to the position of the imaging device to the front - back position difference (X p -X v ), for this reason, the horizontal pitch angle is used to adjust the horizontal viewing angle of the imaging device to ensure that the line of sight of the imaging device can be horizontally aligned with the target point.

[0067] Among them, since the pitch angle is the arctangent of the ratio of the height difference (Z p -Z v ) of the target point (i.e., the elevated worker) relative to the position of the imaging device to the horizontal distance of the target point, by calculating the ratio of the vertical difference to the horizontal distance, the pitch angle can determine the angle at which the camera needs to tilt up or down to accurately align with the target point. This angle enables the camera to be vertically aligned with the target.

[0068] In addition, in this step, the focal length of the imaging device can also be adjusted. The focal length of the imaging device here is related to the distance d between the elevated worker and the imaging device.

[0069] In this way, the focal length f can be expressed as: Among them, H sensor is the height of the camera sensor, and H person is the actual height of the person.

[0070] The adjustment processes of the above three parameters are all to ensure that the elevated worker is in the center of the imaging device's frame. The specific calculation relationships between the parameters of the imaging device and the person's position can be preset according to the definitions of the parameters and the shooting requirements.

[0071] In some embodiments, when the person working at height is in the process of moving, the attitude of the imaging device can be continuously adjusted according to the movement of the person working at height. Therefore, further, the dynamic tracking method for high-risk operation personnel further includes:

[0072] S104. Obtain the movement trend of the person working at height, and adjust the imaging device based on the movement trend.

[0073] After controlling the movement of the imaging device through the above step S103 so that the person working at height is located at a predetermined position in the imaging screen, in this step, obtain the movement trend of the person working at height, and adjust the imaging device based on the movement trend.

[0074] Specifically, predict the movement trend of the person working at height according to the current position of the person working at height, and adjust the imaging device according to the movement trend of the person working at height for risk prediction, as Figure 2 shown, specifically including the following steps:

[0075] S201. Obtain the position at the next moment based on the position of the person working at height at the current moment.

[0076] In this step, obtain the position at the next moment based on the position of the person working at height at the current moment. Specifically, assume that the position of the person working at height captured by the imaging device at the current moment t is S(t), then the position at the next moment, i.e., t + Δt, can be predicted and obtained through the following formula: where, is the rate of change of the position at the current moment t, which can be expressed as: (v x , v y , v z ).

[0077] Specifically, assume S(t) = (x, y, z), then

[0078] where the velocity components can be calculated from historical data:

[0079]

[0080]

[0081]

[0082] where, x t-1 , y t-1 , z t-1 are the position coordinates of the person working at height at the previous Δt moment, respectively.

[0083] In this way, through geometric and spatial distance calculations, it can be automatically determined whether the person climbing is above or adjacent to the climbing carrier. This determination can be used to control the perspective adjustment of the camera to focus on the operator, and at the same time, it can also trigger the alarm function of the safety monitoring system to further enhance the safety of high-risk operations.

[0084] S202. Adjust the imaging device based on the position of the person climbing at the next moment.

[0085] After obtaining the position at the next moment based on the position of the person climbing at the current moment through the above step S201, in this step, the imaging device is adjusted based on the position of the person climbing at the next moment. Specifically, through the predicted position, according to the formulas for the pitch angle, horizontal rotation angle, and focal length of the above imaging device, the pitch angle, horizontal rotation angle, and focal length of the imaging device can be recalculated and the attitude of the imaging device can be adjusted in a timely manner. In this way, possible risks can be predicted based on the movement trend of the person.

[0086] For example, if the predicted trajectory of the person shows that they are about to exceed the safety boundary or may fall, the system can issue an alarm and further adjust the imaging device to continuously track the state of the person. Through the implementation of the above mathematical models and algorithms, the system realizes precise dynamic monitoring of the person climbing. By automatically adjusting the perspective and focal length of the imaging device and predicting the movement trend of the person in real time, it not only improves the accuracy and response speed of monitoring, but also can issue early warnings before potential risks occur, significantly enhancing the safety monitoring ability of high-risk operations.

[0087] The above method of this embodiment is aimed at the special scenario of climbing operations. First, the positions of the climbing carrier and the person to be measured are identified, and then the relative position between the person to be measured and the climbing carrier is obtained; according to the relative position between the person to be measured and the climbing carrier, after determining that the person to be measured is a person climbing, the imaging device is controlled to adjust the perspective and focal length so that the person climbing is always located in the center of the picture; in addition, it can also predict the movement trend of the person climbing according to the current posture of the person climbing, and adjust the imaging device according to the movement trend of the person climbing for risk prediction, so as to significantly enhance the safety monitoring ability of high-risk operations. Through automated and intelligent means, the system can quickly respond and track in real time when a person climbs, reducing the accident risk caused by manual operation delays or negligence. In addition, the front-end intelligent recognition greatly reduces the dependence on back-end personnel, making the monitoring system more efficient and accurate.
