Technical Field

[0001] This disclosure relates to the field of computer technology, and specifically to a method, system, computer device, and storage medium for improving the safety of flying cars. Background Technology

[0002] Flying cars are vehicles equipped with flight capabilities. In related technologies, the safety of flying cars relies on their ability to automatically detect anomalies. If, due to malfunctions such as network failures preventing the acquisition of necessary data for anomaly detection, or if the software used for anomaly detection malfunctions, the flying car cannot perform this self-detection. Consequently, when anomalies occur, the driver will be unaware, and the system designed to troubleshoot will fail to take appropriate action, ultimately leading to safety risks. Therefore, improving the safety of flying cars is a problem that needs to be addressed. Summary of the Invention

[0006] The target system generates a flight status judgment result for each of the at least one target flying cars based on the current appearance characteristics of the target flying car and the registered appearance characteristics of the target flying car.

[0011] For each of the at least one target flying car, when the flight status judgment result of the target flying car indicates that the target flying car has an anomaly, an alarm is issued using a device with alarm function within a preset size area centered on the projection point of the target flying car's current location on the ground, so as to remind pedestrians on the road and drivers of vehicles on the road within the preset size area centered on the projection point of the target flying car's current location on the ground to pay attention to safety.

[0012] In one alternative implementation, a device with an alarm function is mounted on a calibration rod used to determine the altitude of the target flying car.

[0013] In one optional implementation, the device with alarm function is an LED light for alarm purposes, and the alarm is the flashing of the LED light for alarm purposes.

[0014] Secondly, embodiments of this disclosure provide a system for improving the safety of flying cars.

The target image is obtained by the target camera capturing airspace for flying car passage, and the target flying car is a flying car with registered appearance features.

For each of the at least one target flying car, when the flight status judgment result indicates that the target flying car is abnormal, the flight status judgment result is sent to the target flying car.

[0015] In one alternative implementation, the target system, which is not part of the target flying car but communicates with the target flying car, is further configured to determine the altitude of each of the at least one target flying car and to send the altitude of the target flying car to the target flying car.

[0016] In an optional implementation, the system for improving the safety of flying cars further includes: a device with an alarm function, which issues an alarm when the flight status judgment result of the corresponding target flying car indicates that the corresponding target flying car has an anomaly, so as to remind pedestrians on the road and drivers of vehicles on the road within a preset size area centered on the projection point of the current location of the corresponding target flying car on the ground, and the device with the alarm function within the preset size area centered on the projection point of the current location of the corresponding target flying car on the ground.

For each of the at least one target flying car, the target system generates a flight status assessment result based on the current appearance features and the registered appearance features of that target flying car.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0027] refer to Figure 1 The diagram illustrates an example flowchart of a method for improving the safety of flying cars provided by embodiments of this disclosure.

[0028] In step S101, when a target system that does not belong to the target flying car but communicates with the target flying car detects at least one target flying car based on the target image, it acquires the current appearance features of at least one target flying car based on the target image.

[0029] It should be noted that steps S101-S103 are executed repeatedly. Each time the target camera captures an image, that image is used as the target image, and steps S101-S103 are executed, thereby enabling real-time safety monitoring of the flying car.

[0030] In this embodiment of the disclosure, the target system does not belong to any particular flying car; that is, the target system is not part of any flying car system. The target system can communicate with any flying car to which the method for improving the safety of flying cars provided in this disclosure is applied via a wireless communication link.

[0031] As an example, a target system that is not part of the target flying car but communicates with the target flying car includes: a computer device for performing steps S101-S103. The computer device for performing steps S101-S103 communicates with the target flying car through a wireless communication link between the computer device for performing steps S101-S103 and the target flying car.

[0032] As an example, the target system that is not part of the target flying car but communicates with it includes: a computer device for performing steps S101-S102, and a traffic management system for performing step S103. The traffic management system for performing step S103 communicates with the target flying car through a wireless communication link between the traffic management system for performing step S103 and the target flying car.

[0033] In this embodiment of the disclosure, the target image is obtained by capturing the airspace used for the flying car's passage using a target camera. The airspace used for the flying car's passage is within the field of view (FOV) of the target camera.

[0034] The target image was captured by the target camera while at least one target flying car was flying in the airspace used for flying car passage.

[0035] As an example, the target cameras are set on corresponding poles on both sides of the road.

[0036] In this embodiment of the disclosure, the target flying car is a flying car with registered appearance features.

[0037] Multiple license plate numbers for flying cars can be pre-established to correspond to multiple registered appearance features. Each flying car's license plate number corresponds to one registered appearance feature.

[0038] In step S101, a target detection network such as YOLO can be used to perform target detection on the target image.

[0039] A target flying car can be detected by detecting its license plate number.

[0040] For a detected license plate and a detected vehicle in a target image, if the detected license plate is located within the area occupied by the detected vehicle, then the detected license plate can be identified as the license plate of the detected vehicle. It can also be determined whether the detected vehicle's license plate corresponds to a registered appearance feature. If the detected license plate corresponds to a registered appearance feature, then the vehicle to which the detected vehicle belongs is the target flying car, and the registered appearance feature corresponding to the detected license plate is the registered appearance feature of the detected vehicle.

[0041] In this embodiment of the disclosure, the current appearance features of the target flying car may include: the current profile of each rotor of the target flying car and the current profile of each detected door of the target flying car.

[0042] One of the rotors of the target flying car was detected because the rotor object in the target image was detected. The rotor object is the object representing the rotor in the target image.

[0043] A detected door of the target flying car is detected because the door object of the detected door is detected in the target image, which is the object in the target image that represents the detected door.

[0044] The current profile of one rotor of the target flying car is: the profile of the rotor object in the target image. The profile of the rotor object can be extracted from the target image, thus obtaining the current profile of the rotor.

[0045] The current contour of a detected door of the target flying car is: the contour of the door object in the target image. The contour of the detected door object can be extracted from the target image, thus obtaining the current contour of the detected door.

[0046] In step S102, the target system that does not belong to the target flying car but communicates with the target flying car generates a flight status judgment result for each of the at least one target flying car, based on the current appearance characteristics of the target flying car and the registered appearance characteristics of the target flying car.

[0047] In step S102, for a target flying car, when generating a flight status judgment result for the target flying car based on its current appearance features and its registered appearance features, the similarity between the current contour of each rotor and the preset contour of that rotor in the registered appearance features of the target flying car can be calculated for each rotor. If the similarity between the current contour of each rotor and the preset contour of that rotor in the registered appearance features of the target flying car is greater than a rotor similarity threshold, a detection result indicating that the rotor is normal can be generated. If the similarity between the current contour of each rotor and the preset contour of that rotor in the registered appearance features of the target flying car is less than or equal to a rotor similarity threshold, a detection result indicating that the rotor is abnormal can be generated. For each detected door of the target flying car, if the similarity between the current outline of the detected door and the preset outline of the detected door in the registered appearance features of the target flying car is greater than a door similarity threshold, a detection result indicating that the door is normal can be generated. For each detected door of the target flying car, if the similarity between the current outline of the detected door and the preset outline of the detected door in the registered appearance features of the target flying car is less than or equal to a door similarity threshold, a detection result indicating that the door is abnormal can be generated.

[0048] In step S102, for a target flying car, when the detection result of at least one rotor of the target flying car indicates a rotor abnormality and / or the detection result of at least one detected door of the target flying car indicates a door abnormality, a flight condition judgment result indicating that the target flying car has an abnormality is generated.

[0049] In step S102, for a target flying car, when the detection results of each rotor of the target flying car indicate that the rotor is normal and the detection results of each detected door of the target flying car indicate that the door is normal, a judgment result indicating that the target flying car is in normal flight condition is generated.

[0050] In step S103, for each of the at least one target flying car, when the flight status judgment result of the target flying car indicates that the target flying car has an anomaly, the flight status judgment result of the target flying car is sent to the target flying car.

[0051] In this embodiment of the disclosure, when a target flying car malfunctions, the flight status assessment result of the target flying car is sent to the target flying car. Thus, the driver of the target flying car can be notified of the malfunction, and the system for troubleshooting the malfunction can take appropriate actions to resolve the issue, thereby improving the safety of the target flying car.

[0052] In an optional implementation, the system further includes: a target system that is not part of the target flying vehicle but communicates with the target flying vehicle, determining the altitude of each of the at least one target flying vehicle, and sending the altitude of the target flying vehicle to the target flying vehicle.

[0053] As an example, calibration poles can be pre-installed on both sides of the road to determine the altitude of the flying car. A world coordinate system can be established with the top of the calibration pole as the origin. The target image includes a calibration pole object representing one of the calibration poles. Using an algorithm that calculates the distance between two points in space corresponding to two points based on the distance between the top of the calibration pole object and the target flying car object representing the target flying car in the target image, and the pose of the target camera, the distance between the target flying car and the top of the calibration pole is calculated. The altitude of the target flying car is obtained by adding the altitude of the calibration pole to the distance between the target flying car and the top of the calibration pole.

[0054] In this embodiment, a target system that is not part of the target flying car but communicates with it can also send the target flying car's altitude to it. This avoids the problem of the target flying car's altitude measurement system failing to obtain the altitude when it malfunctions, further enhancing the safety of the target flying car.

[0055] In an optional implementation, the method further includes: for each of the at least one target flying cars, when the flight status judgment result of the target flying car indicates that the target flying car has an anomaly, using a device with an alarm function within a preset size area centered on the projection point of the current location of the target flying car on the ground, to remind pedestrians on the road and drivers of vehicles on the road within the preset size area centered on the projection point of the current location of the target flying car on the ground to pay attention to safety.

[0056] The projection of the target flying car's current location onto the ground is obtained by projecting the target flying car's current location onto the ground.

[0057] The current location of the target flying car can refer to its location at the moment the target image was acquired.

[0058] The shape of the area of ​​a preset size centered on the projection point of the target flying car's current location on the ground can be a preset shape. As an example, the area of ​​a preset size centered on the projection point of the target flying car's current location on the ground can be a circular area with a preset radius centered on the projection point of the target flying car's current location on the ground.

[0059] When a target flying car malfunctions, it alerts pedestrians and drivers of vehicles on the road within a preset area centered on the projection of the target flying car's current location on the ground, allowing them to take appropriate measures to ensure their safety.

[0060] In one alternative implementation, a device with an alarm function is mounted on a calibration rod, which is used to determine the altitude of the target flying car.

[0061] In one optional implementation, the device with alarm function is an LED light for alarm purposes, and the alarm is caused by the flashing of the LED light for alarm purposes.

[0062] As an example, the LED light is red.

[0063] An anomaly can be clearly indicated by flashing LED lights. Pedestrians and drivers of vehicles on roads within a preset area centered on the projection of the target flying car's current location on the ground are likely to notice the anomaly.

[0064] This disclosure provides a system for improving the safety of flying cars.

For each of the at least one target flying car, a flight status judgment result is generated based on the current appearance features and the registered appearance features of the target flying car. For each of the at least one target flying car, when the flight status judgment result indicates that the target flying car has an anomaly, the flight status judgment result is sent to the target flying car.

[0066] In one alternative implementation, the target system, which is not part of the target flying car but communicates with the target flying car, is further configured to determine the altitude of each of the at least one target flying car and to send the altitude of the target flying car to the target flying car.
