Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. 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 application.
Like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Fig. 1 is a schematic flow chart of a rescue alarm method provided in an embodiment of the present application, and as shown in fig. 1, the method includes:
step 101, sending rescue alarm information to a target alarm person to obtain a short message based on a mobile phone number used by the target alarm person for calling rescue; the rescue alarm information acquisition short message comprises longitude and latitude, altitude and live-action photo acquisition links.
Specifically, the target area where the target alarm person is located in the embodiment of the invention refers to an urban overpass area, a mountain land terrain road section, a remote area road section, a scenic spot and other areas with complex terrains. The traffic conditions in such areas are often complex, and the difficulty is increased for confirming the accurate position of the target alarm personnel when the demand of rescuing and alarming is required. When an alarm person in a region with a complex terrain gives an alarm and calls for help, the alarm person usually needs to wait for a long time for a rescue to give an alarm because the navigation precision is insufficient or the electric quantity of mobile terminal equipment carried by the alarm person is insufficient to continuously navigate to find an escape exit or a specific rescue place to give an alarm.
When a trapped alarm person (namely, a target alarm person) in a target area dials an alarm phone to call for rescue through communication equipment such as a mobile phone, a background server of a rescue alarm-out center can quickly acquire a mobile phone number used by the target alarm person to call for rescue, and sends a rescue alarm-out information acquisition short message to the target alarm person, wherein the rescue alarm-out information acquisition short message is used for acquiring longitude and latitude, altitude and live-action photos of the position of the target alarm person so as to determine the accurate position of the target alarm person, and the rescue alarm person can conveniently and efficiently carry out rescue. Correspondingly, the rescue alarm-outgoing information acquisition short message comprises a longitude and latitude, an altitude and a live-action photo acquisition link, and after receiving the rescue alarm-outgoing information acquisition short message, the target alarm personnel can click the longitude and latitude, altitude and live-action photo acquisition link to trigger the uploading operation of the longitude and latitude, altitude and live-action photo, and send the longitude and latitude, altitude and live-action photo of the position to the rescue alarm-outgoing center. It will be appreciated that the rescue police dispatch center is an access center for the alarm phone of the target alarm personnel and is also a dispatch center for the rescue alarm personnel. The latitude, longitude and altitude may be obtained through a positioning device of the communication device of the target alarm person, and may also be obtained through positioning software in the communication device, which is not specifically limited in this embodiment of the present application. The live-action photo may be obtained by the target alarm person through the communication device, and the live-action photo is preferably a photo including scenes (hereinafter referred to as identification scenes) which are helpful for identifying the location of the target alarm person, for example, a photo including identification scenes such as roads, road signs, mountain peaks, trees, and the like. According to the embodiment of the application, the identification scene prompt information can be added into the rescue alarm information acquisition short message based on the type of the target area where the target alarm personnel is located, so that the target alarm personnel can conveniently shoot the corresponding live-action picture, and the position where the target alarm personnel is located can be accurately determined subsequently.
It is worth noting that the difference between the residential area and the target area is fully considered, for the residential area, due to the fact that the terrain is simple, the longitude and the latitude of the alarm personnel can be located through a corresponding locating means, the accurate position information of the alarm personnel can be determined, and the alarm personnel can be quickly searched even if certain deviation exists in the longitude and the latitude. However, for the target area, for example, the scenic spot, since the terrain is complex, there are many obstacles (such as trees, etc.), and the position identifiers (such as road signs, buildings, etc.) are few, it is difficult to determine the location accurately by dictation of the alarm person, and even if the latitude and longitude deviation is large due to the above-mentioned terrain, etc., by collecting the latitude and longitude positioning information of the alarm person, it is difficult to obtain the accurate location of the alarm person. However, for areas with complex terrain, the requirement for positioning accuracy is higher, and the alarm is usually missoured, for example, the alarm is trapped at the peak a, but the alarm is positioned at the adjacent peak B due to the longitude and latitude errors, when the alarm is rescued to reach the peak B, the alarm finds that the position information is wrong, and only turns back to reach the peak a, which greatly reduces the rescue efficiency, and for the alarm in critical conditions, the rescue may fail because of the wrong position information. Meanwhile, for a target area, altitude information is also important, and the traditional mode of determining the position of the person to be rescued is not suitable, for example, the alarm person is located on the top of a mountain, but the information cannot be acquired through the longitude and latitude, so that the accurate position of the alarm person cannot be positioned.
Based on the reasons, the embodiment of the application sends the rescue alarm-giving information acquisition short message comprising the longitude and latitude, the altitude and the live-action photo acquisition link to the target alarm person to acquire the longitude and latitude, the altitude and the live-action photo of the position of the target alarm person, and accurately determines the position of the target alarm person through the longitude and latitude, the altitude and the live-action photo of the position of the target alarm person, so as to perform efficient rescue in the subsequent process. It can be understood that the longitude and latitude, altitude and live-action photo obtaining link may be three separate links or one combined link as long as the longitude and latitude, the altitude and the live-action photo of the position where the target alarm person is located can be obtained, and the specific implementation manner of the embodiment of the present application is not specifically limited.
And 102, receiving longitude and latitude information, altitude information and a plurality of live-action pictures which are fed back by the target alarm personnel based on the longitude and latitude, the altitude and the live-action pictures, and determining the position range of the target alarm personnel according to the longitude and latitude information and the altitude information.
Specifically, after receiving the longitude and latitude information, the altitude information and the multiple live-action pictures fed back by the target alarm person based on the longitude and latitude, the altitude and the live-action pictures, the rescue alarm center can determine the position range of the target alarm person according to the longitude and latitude information and the altitude information. Based on the foregoing, it can be understood that the latitude and longitude information and the altitude information may have a large deviation due to the influence of factors such as the terrain of the target area, and therefore, in the embodiment of the present application, the position range of the target alarm person is determined based on the preset latitude and longitude information and the preset altitude information fluctuation range, and the target alarm person is ensured to be located in the position range, so as to lock the accurate position of the target alarm person subsequently. It is to be understood that the preset latitude and longitude information and the fluctuation range of the altitude information may be determined in advance based on the fluctuation result of the field measurement, or may be determined based on experience, and this is not particularly limited in the embodiment of the present application. Meanwhile, in order to quickly determine the accurate position of the target alarm person through the live-action pictures, the live-action pictures are multiple pictures shot at different angles, and correspondingly, live-action picture shooting angle and shooting quantity prompt information can be added to the rescue alarm information acquisition short message, so that the target alarm person can send the live-action pictures meeting the shooting angle and quantity requirements, and the accurate position of the target alarm person can be determined subsequently.
Step 103, sampling the live-action corresponding to a plurality of preset positions within the position range in the live-action map of the target area at a first frequency to obtain a first live-action sampling picture set, matching the first live-action sampling picture set with the live-action photos, and determining the estimated position of the target alarm personnel and the corresponding position matching degree.
Specifically, in the embodiment of the application, live-action pictures (namely, live-action sampling pictures) corresponding to different positions in the target area can be acquired based on the live-action map of the target area, and the accurate position of the target alarm person can be determined based on the comparison result between the live-action sampling pictures and the live-action pictures fed back by the target alarm person. It can be understood that the target area real scene map may be an existing map software, or may be a map software designed for a target area scene and only including a target area real scene, which is not specifically limited in this embodiment of the present application. More specifically, this application embodiment is confirming after target warning personnel's position scope, can be based on target warning personnel's position scope is confirmed target area that target warning personnel are located at present, recall the outdoor scene map that the target area corresponds can be to being in outdoor scene that a plurality of preset positions in the position scope correspond samples obtains first outdoor scene sampling picture set, because only with right outdoor scene that a plurality of preset positions in the position scope correspond samples, can improve target warning personnel position search's efficiency greatly. As for the specific number of the preset positions, the preset positions may be set as required, and this is not specifically limited in the embodiment of the present application.
The sampling, with a first frequency, the real scenes corresponding to a plurality of preset positions within the position range in the real scene map of the target area specifically includes: and carrying out multi-angle sampling on the live-action scenes corresponding to the preset positions to obtain sampling pictures with a first preset number, wherein the first preset number corresponds to the first frequency. It can be understood that the live-action sampling pictures corresponding to the live-action pictures fed back by the target alarm personnel and corresponding to the preset positions are also multi-angle pictures, preferably, the number of the sampling angles of the live-action sampling pictures is larger than the number of the shooting angles of the live-action pictures, so that on the basis of ensuring the subsequent matching efficiency, the matching precision is ensured as far as possible, and the matching failure caused by too low richness of the sampling angles is avoided. The first preset number may be equal to the first frequency, or may be in other proportional relationship with the first frequency, as long as it is ensured that the first preset number is greater than the number of the live-action photos. Based on this, for each preset position in the plurality of preset positions, a first preset number of sampling pictures can be obtained, and the live-action sampling pictures corresponding to each preset position are collected, so that the first live-action sampling picture set can be obtained.
After the first live-action sampled picture set is obtained, the first live-action sampled picture set and the live-action photos can be matched. It is to be understood that, substantially, matching the first set of live-action sampled pictures with the live-action photos matches the live-action sampled pictures corresponding to the preset positions with the live-action photos respectively, so as to determine the preset position with the highest matching degree with the live-action photos. Regarding the matching degree metric, the embodiment of the present application is determined based on the similarity between the live-action sampled picture and the live-action photo, specifically: for a certain preset position, firstly obtaining a real scene sampling picture corresponding to the preset position, then comparing each real scene sampling picture corresponding to the preset position with each of a plurality of real scene pictures, determining a target real scene sampling picture with the highest similarity to each real scene picture, then carrying out summary operation on the similarities corresponding to the target real scene sampling pictures, and taking the summary operation result (namely, the comprehensive similarity) as the position matching degree of the preset position and the position where a target alarm person is located. Preferably, the summarizing operation is an averaging operation, and of course, the summarizing operation may also adopt other operation modes capable of reflecting the comprehensive similarity, such as summation, and the embodiment of the present application is not particularly limited to this. It can be understood that the similarity between the live-action sampled picture and the live-action photo can be determined based on a corresponding picture comparison algorithm, and as for a specific type of the picture comparison algorithm, this embodiment of the present application is not specifically limited thereto.
It should be noted that, in a normal situation, the target preset position completely matched with the position where the target alarm person is located, among the corresponding live-action sample pictures, the target live-action sample picture with the highest similarity to each live-action photo should have the corresponding similarity of 100%. Taking the summary operation as an example of averaging, the corresponding position matching degree is 100%. However, as can be seen from the foregoing, the number of sampling angles of the live-action sampled pictures is greater than the number of shooting angles of the live-action pictures, but in consideration of ensuring the matching efficiency, the first frequency in the embodiment of the present application is not set too large (accordingly, the first predetermined number is not set too large), so as to avoid a huge matching workload. The setting mode may cause that the sampling angle of the live-action sampling picture may be different from the shooting angle of the live-action picture, so that a certain deviation may exist in a final matching result, and if the sampling angle of the live-action sampling picture corresponding to the target preset position is greatly different from the shooting angle of the live-action picture, the matching degree of the corresponding position may even be lower than that of other preset positions, thereby causing that the position of the target alarm person cannot be determined.
However, it can be understood that, since the target preset position is the same as the position where the target alarm person is located, even if the sampling angle of the live-action sampling picture is different from the shooting angle of the live-action picture, the position matching degree is not too low. Based on this, the embodiment of the application presets a first position matching degree threshold, screens out one or more candidate positions (namely estimated positions) based on the first position matching degree threshold, and then further collects and matches the real scenes corresponding to the estimated positions to determine the accurate positions of the target alarming personnel. Based on the mode of the embodiment of the application, the position of the target alarm personnel can be prevented from being eliminated in the matching process on the basis of reducing the matching workload as much as possible, and the efficiency and the accuracy of determining the position of the target alarm personnel are ensured. It can also be understood that if the estimated positions meeting the requirements are obtained based on the non-screening of the matching degree threshold, a plurality of preset positions are reselected, and corresponding live-action sampling and matching processes are executed until one or more estimated positions are determined.
And 104, determining a second frequency corresponding to each estimated position according to the position matching degree, sampling the real scene corresponding to each estimated position in the real scene map of the target area by using the second frequency to obtain a second real scene sampling picture set, and matching the second real scene sampling picture set with the real scene picture to obtain the confirmed position of the target alarm personnel.
Specifically, after the estimated positions and the corresponding position matching degrees of the target alarming personnel are determined, the second frequency corresponding to each estimated position can be determined according to the position matching degrees, and the live-action corresponding to each estimated position in the live-action map of the target area is sampled by the second frequency. The sampling of the real scenes corresponding to the pre-estimated positions in the real scene map of the target area at the second frequency specifically includes: and carrying out multi-angle sampling on the real scenes corresponding to the pre-estimated positions to obtain sampling pictures with a second preset number, wherein the second preset number corresponds to the second frequency. It is understood that the second predetermined number may be equal to the second frequency or in other proportional relationship with the second frequency, but preferably, the proportional relationship between the second predetermined number and the second frequency is the same as the proportional relationship between the first predetermined number and the first frequency. On this basis, the value of the second frequency can be determined quickly.
More specifically, based on the foregoing, it can be seen that the sampling angle of the live-action sampled picture obtained based on the first frequency sampling may be different from the shooting angle of the live-action picture, and therefore, a certain deviation may exist in a final matching result, and if the sampling angle of the live-action sampled picture corresponding to the target preset position is greatly different from the shooting angle of the live-action picture, the corresponding position matching degree may be even lower than that of other preset positions. Based on this, in the embodiment of the present application, in order to ensure the accuracy of the final matching result, the second frequency corresponding to each estimated position is determined according to the position matching degree, and it can be understood that, in order to ensure that the sampling angle covers the shooting angle of the live-action photograph as much as possible, the second frequency should be greater than the first frequency. Meanwhile, when a target preset position exists in the estimated positions, if the position matching degree corresponding to the target preset position is lower than that of other preset positions in the estimated positions, sampling is performed on each estimated position by adopting the same second frequency, so that the corresponding position matching degree is still lower than that of other estimated positions when the target preset position is subjected to secondary matching (namely the second live-action sampling picture set is matched with the live-action picture), and further the position where a target alarm person is located is determined wrongly. Based on this, the second frequency corresponding to each estimated position is determined according to the position matching degree in the embodiment of the present application, and specifically, the position matching degrees corresponding to each estimated position are sorted, and the lower the position matching degree is, the higher the corresponding second frequency is. By adopting the method, the position determination error of the target alarm personnel can be avoided as much as possible on the basis of reducing the workload of secondary matching. As for the corresponding relationship between the position matching degree and the second frequency, the determination and the adjustment may be performed according to actual needs, which is not specifically limited in the embodiment of the present application.
It should be understood that, similar to the aforementioned process of matching the first real-scene sampled picture set with the real-scene pictures, the second real-scene sampled picture set is matched with the real-scene pictures, that is, the real-scene sampled pictures corresponding to the estimated positions are respectively compared with each of the real-scene pictures to determine the position matching degree of each estimated position, and the confirmed position of the target alarm person (i.e., the aforementioned target preset position) is determined based on a preset second position matching degree threshold. It can also be understood that, taking the summary operation as an example of averaging, the corresponding second position matching degree threshold should be 100% theoretically, but considering the influence of factors such as environmental factors, the similarity calculation itself may have a certain deviation, and therefore, in the actual application process, the second position matching degree threshold may be finely adjusted based on specific situations, for example, adjusted to 99%, and the embodiment of the present application is not limited to this specifically.
It is understood that if the confirmation location meeting the threshold requirement still cannot be obtained by the second matching, step 103 and step 104 are executed in a loop until the confirmation location of the target alarm personnel is determined.
And 105, determining target rescue police-out personnel and a corresponding rescue police-out route based on the confirmed positions of the target alarm personnel and the current state of the rescue police-out personnel, and indicating the target rescue police-out personnel to rescue out police based on the rescue police-out route.

Specifically, since the terrain of the target area is complex and the road conditions are relatively complex, unlike rescue in residential areas, a person who rescues an alarm can go to the corresponding rescue vehicle (e.g., a car) to perform rescue, the rescue in the target area first needs to consider whether a vehicle equipped with the person who rescues an alarm is suitable for going to the rescue, and if so, a rescue alarm route and corresponding time consumption are determined based on the vehicle equipped with the person who rescues an alarm. Meanwhile, in residential area rescue, due to the fact that road and road condition information is very clear, a rescue path can be conveniently planned only through existing map software, but due to the fact that terrain and road conditions of a target area are complex, effective rescue paths cannot be planned through the existing map software. Based on this, after determining the confirmed position of the target alarm person, the embodiment of the application needs to determine the current position of the rescue alarm person and the equipped transportation means, so as to determine the rescue alarm person capable of implementing rescue, further plan a rescue alarm route and determine the target rescue alarm person capable of implementing rescue at the fastest speed.

It can be understood that, for a target area provided with a road sign, the embodiment of the application can quickly and accurately determine the currently available road information by combining the road image and the road sign image, and for a part of target areas not including the road sign, the currently available road information can also be accurately determined by the target identification algorithm. The current available road information comprises a current available road and corresponding road condition information, and due to the fact that the road condition in the target area is complex, the corresponding road condition information must be fully considered besides the current available road is determined, and the situation that rescue alarm output efficiency is reduced due to unreasonable rescue alarm output route planning and time-consuming calculation deviation is avoided. After the current available road information is accurately determined, optional rescue alarm routes between different rescue alarm personnel and the target alarm personnel and time consumption corresponding to the optional rescue alarm routes can be determined based on the confirmed positions of the target alarm personnel, the current positions of the rescue alarm personnel and the equipped vehicles and by combining the current available road information in the real-scene map of the target area. It can be understood that the selectable rescue alarm-giving route includes a specific rescue alarm-giving route and a travel mode corresponding to different road sections in the rescue alarm-giving route, for example, the first road section travel mode of the rescue alarm-giving route a is motorcycle, the second road section travel mode is walking, of course, the travel mode is determined based on a vehicle equipped for the rescue alarm-giving personnel, and is not limited to motorcycle, walking, climbing, rowing and the like, which is not exhaustive in the embodiments of the present application.

It is understood that the target rescue alarm personnel can reach the rescue alarm personnel at the position of the target alarm personnel most quickly.
According to the method provided by the embodiment of the application, based on the confirmed position of the target alarm personnel, the current position of the rescue alarm personnel and the equipped transportation means, the current available road information in the target area live-action map is combined, and the selectable rescue alarm routes between the rescue alarm personnel and the target alarm personnel and the time consumption corresponding to the selectable rescue alarm routes are determined; the current available road information comprises a current available road and corresponding road condition information; the current available road information is determined based on the road image and the road identification image in the target area live-action map, and the target rescue police-out personnel and the corresponding rescue police-out route are determined based on the corresponding time consumption of each selectable rescue police-out route, so that the accurate scheduling of the rescue police-out personnel can be realized, the rescue of the rescue police-out personnel can be implemented in the shortest time, and the rescue police-out efficiency is improved.

Based on the reasons, the embodiment of the application can update the available road information based on the current weather information, and further adjust the rescue alarm route based on the updated current available road information, so that the situation that the rescue alarm route is unavailable due to the weather reasons and further the rescue alarm efficiency is influenced is avoided. Specifically, the method comprises the following steps:
and a background server of the rescue police-out center can acquire the current weather information in real time and determine the updating frequency of the available road information based on the current weather information. It will be appreciated that the more severe the weather conditions, the higher the corresponding update frequency. After the update frequency of the available road information is determined, the current available road information in the real-scene map of the target area can be updated according to the update frequency, and the update mode of the current available road information is as follows: and determining whether the road corresponding to the current rescue police-out route can pass or not based on the road image in the target area live-action map. The determination method of whether the vehicle can pass or not may be to determine whether the road still exists or whether the road includes an obstacle that affects the passing, and of course, other feasible determination methods may also be adopted, which is not specifically limited in this embodiment of the application.
