Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the above technical problems, embodiments of the present invention provide a traffic guidance method, a device, and a device, where the method and the device may be applied to a platform device in a traffic guidance system, or may also be applied to other electronic devices, and are not limited specifically. First, a traffic guidance method according to an embodiment of the present invention will be described in detail below. For convenience of description, the execution body is referred to as a platform device in the following embodiments.
Fig. 1 is a first flowchart of a traffic guidance method according to an embodiment of the present invention, including:
s101: and acquiring a panoramic video, and mapping the geographic position information to the panoramic video to obtain a video map.
The field range of the panoramic video is large. For example, videos collected by a plurality of bolt cameras can be spliced to obtain a panoramic video. In the splicing process, the spliced images can be subjected to distortion removal processing so as to improve the splicing effect. The multiple bolt faces may be positioned higher to capture a panoramic video of a large field of view. Or, the video collected by the dome camera can be used as the panoramic video, and the position of the dome camera can be higher, so that the panoramic video with a large view field can be acquired. Or, the video collected by the dome camera and the video spliced by the plurality of gun shots can be spliced to obtain a more complete panoramic video, which is also possible.
For example, a GIS (Geographic Information System) map corresponding to the panoramic video may be obtained, and the Geographic position Information in the map is mapped to the panoramic video. Or, the geographic position information may be mapped to the panoramic video in a calibration manner, so as to obtain the video map.
S102: and if the traffic event exists in the panoramic video, generating a command scheme aiming at the traffic event according to the traffic resource acquired in advance.
In one embodiment, whether a traffic event exists in the panoramic video can be judged by analyzing the panoramic video, and if so, a command scheme for the traffic event is generated according to traffic resources acquired in advance.
In another embodiment, a command scheme for a traffic event corresponding to alarm information may be generated according to traffic resources acquired in advance in the case that the alarm information is received.
For example, the traffic event may be a traffic accident, a traffic jam, a hit-and-run vehicle, or a vehicle passing by which special attention is required, and so on, which are not listed. The recognition model can be trained in advance by utilizing a machine learning algorithm, and whether a traffic event exists in the panoramic video or not can be recognized based on the recognition model. If so, a corresponding instruction scheme is generated for the identified traffic event.
Or the platform device may receive the alarm information sent by the other device, for example, if a traffic accident occurs at the location a, a witness on the scene of the traffic accident may send the alarm information to the platform device by using a mobile phone, where the alarm information may carry the geographical location of the location a, and thus, the platform device generates a command scheme for the traffic accident according to the geographical location of the location a.
For another example, the platform device may receive the alarm information pushed by other application software, for example, some map software may push the alarm information to the platform device when a traffic event is analyzed, and the alarm information may carry a geographical location of the traffic event, so that the platform device generates a command scheme for the traffic event. In addition, other application software can also push videos or snapshot images related to the traffic events to the platform, so that the platform device can acquire richer resources related to the traffic events.
For example, if the traffic event is the escape of a troublemaking vehicle, the generated command scheme may be to send a red-wave task, i.e. to block the troublemaking vehicle, to the control device at the gate through which the troublemaking vehicle may pass. For example, the control device at the gate may be a traffic signal controller, which may control the display of traffic lights, and the traffic signal controller may block the troublemaking vehicle by displaying red lights when the troublemaking vehicle appears, according to the received red wave mission.
If the traffic event is the passing of a ambulance, the generated command scheme may be to send a green wave task, i.e. to clear the ambulance, to the control device at the gate where the ambulance may pass. For example, the control device at the gate may be a traffic signal controller, which may control the display of traffic lights, and the traffic signal controller may allow the ambulance to be cleared by displaying green lights upon the occurrence of the troublemaking car according to the received green wave task.
In one embodiment, generating a command scheme for the traffic event according to the traffic resource acquired in advance may include: determining the geographical position of the traffic event as a first geographical position; determining a gate associated with the first geographical position as a target gate according to traffic resources acquired in advance; the traffic resources comprise resources of a plurality of checkpoints, and the resources of the checkpoints at least comprise the geographical positions of the checkpoints; and generating control information of each target gate according to the attributes of the traffic events.
The traffic resource may include various types, such as "resource at the gate" in this embodiment, and "information on the staff on duty at each geographic location", "positioning information acquired by positioning equipment carried by the staff on duty", and "scene image acquired by image acquisition equipment carried by the staff on duty" in the subsequent embodiments, and may further include information such as road resource, which is not listed. The "resource of the gate" in this embodiment may include a geographical location of the gate, an identifier of the gate, a video captured by a camera disposed at the gate, a snapshot image, and so on.
Attributes of a traffic event may include: hit-and-run, passing of a vehicle requiring special attention, etc., if the attribute is "hit-and-run", the generated control information is control information related to a red wave task, that is, control information for closing the gate, and if the attribute is "ambulance passing", the generated control information is control information related to a green wave task, that is, control information for opening the gate.
Specifically, determining the target mount may include: determining a gate, the distance between which and the first geographical position is less than a preset threshold value, as a target gate according to the geographical positions of a plurality of gates included in the traffic resources acquired in advance; or predicting the track of the monitoring target corresponding to the traffic event according to the geographical positions of a plurality of checkpoints and road resources included in the traffic resources acquired in advance, and determining the checkpoints in the track as target checkpoints.
The monitoring target corresponding to the traffic incident may be the above-mentioned incident causing vehicle, ambulance, etc., and is not limited specifically. The target mount is the mount through which the monitoring target may pass. As described above, the traffic resource may include a resource of the gate, the resource of the gate including a geographic location of the gate; it can be understood that the monitored target may pass through the gate closer to the monitored target with a high probability, and therefore, the gate closer to the first geographical position may be determined as the target gate.
As described above, the traffic resource may include a road resource, and in one case, the traffic resource and the geographic location of each gate may be used to predict gates that the monitoring target may pass through and time periods that the monitoring target passes through, so that the generated control information may include time periods corresponding to red wave tasks or green wave tasks.
For example, assume that the platform device predicts the troublemaking vehicle, based on the driving speed of the troublemaking vehicle, at 10: 00 through bayonet a, 10: 30, when passing through the gate B, the control information of the gate a generated by the platform device is: 10: 00, closing the bayonet A, and generating control information of the bayonet B by the platform equipment as follows: 10: and 30, closing the bayonet B. And the platform equipment sends the generated control information to the control equipment at the corresponding bayonet so as to control the bayonet.
Or, in another case, the platform device may identify a feature of the monitoring target as a feature to be processed, and thus, the generated control information may include the feature to be processed corresponding to the red wave task or the green wave task. And the platform equipment sends the generated control information to corresponding control equipment at the bayonet, a camera arranged at the bayonet extracts the features of the target passing through the bayonet, and if the extracted features are successfully matched with the features to be processed, the control equipment at the bayonet executes a corresponding red wave task or a corresponding green wave task.
For example, if the platform device identifies that the license plate number of the troublemish car is jing a0000, and the platform device determines that the gates through which the troublemish car may pass are gate a and gate B, the control information of gate a generated by the platform is: for closing bayonet A of Beijing A0000, the control information of generating bayonet B by the platform equipment is as follows: bayonet B is closed for jing a 0000. And the platform equipment sends the generated control information to the control equipment at the corresponding bayonet so as to control the bayonet.
For example, if the traffic event is a traffic accident or traffic jam, the generated command scheme may be: and dispatching related duty personnel to process the traffic accidents or the traffic jam. In this embodiment, the traffic resources acquired in advance include "the information of the staff on duty at each geographic location".
In one embodiment, generating a command scheme for the traffic event according to the traffic resource acquired in advance may include: determining the geographical position of the traffic event as a first geographical position; scheduling the on-duty personnel corresponding to the first geographical position to process the traffic event according to the traffic resources acquired in advance; wherein the traffic resources comprise the information of the staff on duty at each geographic location.
In one case, each on-duty person corresponds to a fixed on-duty range, in this case, the on-duty range to which the first geographical location belongs may be determined, and the on-duty person corresponding to the on-duty range may be scheduled to handle the traffic event. And under the other condition, the on-duty personnel carries positioning equipment, the positioning equipment sends the positioning information of the on-duty personnel to the platform equipment, and the platform equipment determines the on-duty personnel which is closest to the first geographical position or most convenient to go to the first geographical position according to the received positioning information, and the on-duty personnel is taken as a target on-duty personnel and is dispatched to process the traffic incident.
S103: and displaying the traffic resource associated with the command scheme in the video map in a label form.
As described above, in one embodiment, the generated command scheme is: generating control information of each target gate; in this case, the traffic resources associated with the command scheme, that is, the resources of the target gate; s103 may include: determining a position mapped to the video map by the target checkpoint according to the geographic position of the target checkpoint, and taking the position as a first video position; at the first video position, a tag of the target checkpoint is presented.
It can be understood that the target gate is a gate through which the monitoring target may pass; the pre-acquired traffic resources comprise the geographic position of the target gate, and the video map also carries geographic position information, so that the target gate can be mapped into the video map.
There are various ways to show the tags of the object checkpoint in the video map. In one case, a label symbol may be added only at the first video position of the video map, and the symbol may be a geometric figure such as an arrow, a triangle, and the like; alternatively, the identification or geographic location of the target checkpoint may also be presented in proximity to the tag symbol.
In another case, not only is a tag symbol added at the first video location, but tag content is displayed at other locations of the video map. As described above, the "resource of the gate" acquired in advance may include a video or a snapshot captured by a camera disposed at the gate, and in this case, the tag content may be a video or a snapshot captured by a camera disposed at the target gate. Referring to fig. 2, a tag symbol (the tag symbol in fig. 2 is a rectangular frame, which is merely an illustration) is presented at a first video position of the video map, and specific tag content is presented at the right side of the video map. This embodiment has a better visual effect.
As described above, in another embodiment, the generated command scheme is: scheduling the on-duty personnel to process the traffic incident; in this case, the traffic resources associated with the command plan, i.e., the information about the scheduled on-duty personnel; s103 may include: receiving positioning information sent by positioning equipment carried by the on-duty personnel as traffic resources associated with the command scheme; generating a mobile tag corresponding to the on-duty personnel according to the positioning information received each time; displaying the mobile tag in the video map.
In the embodiment, the on-duty personnel carry the positioning equipment, and the positioning equipment can send the positioning information of the on-duty personnel to the platform equipment in real time or at intervals. The platform device determines, for each received positioning information, a location at which the positioning information maps to a video map, and adds a tag. In this way, each piece of positioning information corresponds to one tag, each tag presents a moving effect in the video map, and reflects the moving track of the staff on duty, so that the tags are called as the moving tags corresponding to the staff on duty.
In one embodiment, after a duty worker corresponding to a first geographical position is scheduled to process the traffic event, a scene image sent by an image acquisition device carried by the duty worker can be received as a traffic resource associated with the command scheme; and after the mobile tag is presented in the video map, presenting the scene image as the content of the mobile tag in the video map.
In the embodiment, the on-duty personnel not only carry the positioning device, but also carry the image acquisition device, and the image acquisition device sends the scene image acquired by the on-duty personnel on the on-duty road to the platform device. For example, the executive may drive the vehicle to be on duty, so that the Positioning device may be a Global Positioning System (GPS) in the vehicle, and the image capturing device may be an on-board camera. Or, in another case, the positioning device and the image capturing device may be the same device, such as some law enforcement recorders, etc., without limitation.
In this embodiment, the above-mentioned mobile tag added in the video map may be only a tag symbol, and the tag content is displayed at other positions of the video map, and the tag content may be a scene image captured by the image capture device. Referring to fig. 2, a tag symbol is shown at a position where positioning information is mapped to a video map, and specific tag contents are shown at the right side of the video map. This embodiment has a better visual effect.
As an implementation manner, after a duty worker corresponding to a first geographical position is determined, a monitoring image acquired by a monitoring point at the first geographical position is acquired; and pushing the acquired monitoring image to terminal equipment carried by the on-duty personnel corresponding to the first geographical position. In this way, the progress of the traffic incident can be effectively made known to the staff.
As described above, videos collected by a plurality of guns can be spliced to obtain a panoramic video, in this case, a dome camera can be further provided, and the dome camera and the plurality of guns acquire images of a scene of the camera. For example, an eagle eye device may be used, which includes a plurality of bolt guns and a ball machine.
In this case, if a traffic event exists in the panoramic video, determining a corresponding position of the traffic event mapped to the dome camera video as a second video position according to a mapping relation between a coordinate system of the dome camera video acquired by the dome camera and a coordinate system of the video map; and carrying out focusing display on the second video position.
In addition, the labels displayed in the video map can be displayed in the dome camera video according to the mapping relation between the coordinate system of the dome camera video acquired by the dome camera and the coordinate system of the video map.
The zooming and focusing effects of the dome camera are good, so that the traffic events can be gathered and displayed in the dome camera, and the display effect is improved. The video of the dome camera is linked with the video map, and the labels in the video map are displayed in the video of the dome camera at the same time, so that the display effect is further improved.
In addition, a monitoring target (the above-mentioned troublemaker, ambulance, etc.) or a person on duty, etc. may be tracked by the ball machine. For example, the movement trajectory of the tracking target (the monitoring target or the duty person) may be predicted, and the ball machine may be controlled to follow the tracking target according to the movement trajectory. Therefore, related personnel can know richer information related to the tracking target, and the service efficiency is improved.
By applying the embodiment shown in fig. 1 of the invention, on the first hand, when a traffic incident exists, a command scheme for the traffic incident is automatically generated according to the acquired traffic resources, and compared with a mode of conducting command by telephone communication, the command efficiency is improved; in the second aspect, the traffic resources associated with the command scheme are displayed in the video map in a label form, so that the video effect is better.
In some existing schemes, traffic commanders rely on GIS maps and on manual experience to conduct traffic command; in the scheme, the command scheme is automatically generated, the dependence on the manual experience is reduced, the traffic resources related to the command scheme are displayed in the video map in a label mode, and the command process can be displayed more intuitively for traffic commanders.

S302: and if the traffic event exists in the panoramic video, determining the geographical position of the traffic event as a first geographical position.
S303: and determining a gate associated with the first geographical position as a target gate according to the traffic resources acquired in advance.

The resource of the gate may include a geographical location of the gate, an identifier of the gate, a video captured by a camera disposed at the gate, a snapshot, and the like.
In one embodiment, S303 may include: and determining a gate, the distance of which to the first geographical position is less than a preset threshold value, as a target gate according to the geographical positions of a plurality of gates included in the traffic resources acquired in advance.
In another embodiment, S303 may include: and predicting the track of the monitoring target corresponding to the traffic event according to the geographical positions and road resources of a plurality of checkpoints included in the traffic resources acquired in advance, and determining the checkpoints in the track as target checkpoints.
S304: and generating control information of each target gate according to the attribute of the traffic event.
Attributes of a traffic event may include: hit-and-run, passing of a vehicle requiring special attention, etc., if the attribute is "hit-and-run", the generated control information is control information related to a red wave task, that is, control information for closing the gate, and if the attribute is "ambulance passing", the generated control information is control information related to a green wave task, that is, control information for opening the gate.
In one case, the gates that the monitoring target may pass through and the time periods that the monitoring target passes through may be predicted according to the road resources and the geographic positions of the gates (traffic resources acquired in advance), so that the generated control information may include the time periods corresponding to the red wave tasks or the green wave tasks.
For example, assume that the platform device predicts the troublemaking vehicle, based on the driving speed of the troublemaking vehicle, at 10: 00 through bayonet a, 10: 30, when passing through the gate B, the control information of the gate a generated by the platform device is: 10: 00, closing the bayonet A, and generating control information of the bayonet B by the platform equipment as follows: 10: and 30, closing the bayonet B. And the platform equipment sends the generated control information to the control equipment at the corresponding bayonet so as to control the bayonet.
Or, in another case, the platform device may identify a feature of the monitoring target as a feature to be processed, and thus, the generated control information may include the feature to be processed corresponding to the red wave task or the green wave task. And the platform equipment sends the generated control information to corresponding control equipment at the bayonet, a camera arranged at the bayonet extracts the features of the target passing through the bayonet, and if the extracted features are successfully matched with the features to be processed, the control equipment at the bayonet executes a corresponding red wave task or a corresponding green wave task.
For example, if the platform device identifies that the license plate number of the troublemish car is jing a0000, and the platform device determines that the gates through which the troublemish car may pass are gate a and gate B, the control information of gate a generated by the platform is: for closing bayonet A of Beijing A0000, the control information of generating bayonet B by the platform equipment is as follows: bayonet B is closed for jing a 0000.
