The present techniques relate to controlling unmanned aerial vehicles (UAVs). More specifically, the techniques relate to dynamically controlling UAVs.
According to an embodiment described herein, a system can include processor t receive media and an event from a deployed unmanned aerial vehicle (UAV). The processor can also further send the media and the event to an artificial intelligence (AI) service and receive smart insights from the AI service. The processor can also dynamically generate an execution block based on the smart insights. The processor can also send the generated execution block to an edge device for generating vehicle specific commands.
According to another embodiment described herein, a method can include receiving, via a processor, media and an event from a deployed unmanned aerial vehicle (UAV). The method can further include sending, via the processor, the media and the event to an artificial intelligence (AI) service and receiving smart insights from the AI service. The method can also further include dynamically generating, via the processor, an execution block based on the smart insights. The method can also include sending, via the processor, the generated execution block to an edge device for generating vehicle specific commands.
According to another embodiment described herein, a computer program product for dynamically controlling unmanned aerial vehicles (UAVs) can include computer-readable storage medium having program code embodied therewith. The computer readable storage medium is not a transitory signal per se. The program code executable by a processor to cause the processor to receive media and an event from a deployed UAV. The program code can also cause the processor to send the media and the event to an artificial intelligence (AI) service and receive smart insights from the AI service. The program code can also cause the processor to dynamically generate an execution block based on the smart insights. The program code can also cause the processor to send the generated execution block to an edge device for generating vehicle specific commands.
Unmanned aerial vehicles (UAVs), also referred to herein as drones, may be programmed to perform services autonomously. For example, a UAV route and invocation of drone payload may be pre-planned. The payload may include all equipment installed and carried by a deployed drone. The pre-programming may include instructions that determine which data the UAV gathers, which sensors are used to collect the data, and how the data is collected. However, information about real-time environmental conditions may be very limited before the flight of a UAV. Furthermore, a lot of data may be potentially collected during a drone flight from which various insights could potentially be retrieved. Such insight could be used to change various aspects of UAV operation to improve performance. A pre-planned static operation does not allow such insights from real-time environmental conditions to be taken into account when performing services.
According to embodiments of the present disclosure, a computing device can dynamically control UAVs using execution blocks. As used herein, execution blocks are self-contained sequence of commands that can be executed by a deployed UAV without additional information from a server. In some examples, execution blocks may also be executed without additional information from an UAV. An example system includes a processor to receive media and an event from a deployed UAV. The processor is to send the media and the event to an artificial intelligence (AI) service and receive smart insights from the AI service. The processor is to also dynamically generate an execution block based on the smart insights. The processor is to further send the generated execution block to an edge device for generating drone specific commands. Thus, embodiments of the present disclosure allow UAVs to be dynamically controlled in response to particular conditions or detected objects in real-time. In addition, the execution blocks are agnostic to any particular UAV. Thus, the techniques described herein may be used with a variety of different types and specific models of UAVs.
With reference now to
The system 100 of
In the example of
The AI analytics service 106 may be trained to generate smart insights 114 based on the received media and events 112. For example, the AI analytics service 106 may include one or more trained AI models. For example, the AI models may include object detection models, etc., that can be used to identify and locate specific objects or conditions that are included in the generated smart insights 114. In some examples, the AI analytics services 106 may include AI models that are not related to visual recognition and be based on other sensors of the drone. For example, the AI models may be trained to detect temperature, air quality. As one examples, such AI models may use a regressor model to predict a likelihood of fire. In various examples, the AI model used by the AI analytics service 106 may also be changed to a different model in response to the smart insights 114. For example, the different model may be generated by retraining the AI model based on new inputs. The drones solution engine 102 may receive the smart insights 114 from the AI analytics services 106 and generate execution blocks 116 based on the smart insights 114. For example, the execution blocks 116 may each include a particular sequence of commands or set of actions to perform. The execution blocks 116 may include particular routes, and which sensors to activate at which times or locations. In some examples, at least some of the execution blocks may be a predefined sequence of commands. For example, if an area is to be scanned in order to search for a person, a first execution block 116 may be a predefined route that scans the area in some pattern. However, while executing this execution block 116, the system 100 might identify a person. Then, the drones solution engine 102 can generate a new execution block 116 that navigates the deployed drone 108 to a location where the person was detected. In various examples, all execution blocks are dynamically generated. The drones solution engine 102 may then send the generated execution blocks 116 to the drones solution edge 104. The drones solution edge 104 may then generate drone specific commands 118 based on the execution blocks 116. In some examples, the drones solution edge 104 can also use local AI models or services to perform filtering or to adjust execution blocks 116 before generating drone specific commands 118 to be transferred to the drone 108. The drones solution edge 104 can transmit the drone specific commands 118 to the deployed drone 108 as the deployed drone 108 is flying.
The drone specific commands 118 are received by the deployed drone 108. The deployed drone 108 may then execute the drone specific commands 118. For example, the drone specific commands 118 may be used instead of a previous set of specific commands to travel a particular route, select sensors to activate, and when and where to activate the selected sensors. In some examples, the drone specific commands 118 may be received subsequently to a previous set of drone specific commands 118. For example, the deployed drone 108 may request for additional drone specific commands 118 from the drones solution edge 104 and the drone solutions edge 104 may request additional execution blocks 116 from the drones solution engine 102.
In some examples, the drones solution engine 102 may not have an execution block 116 available to send to the drones solution edge 104 when a previous set of drone specific commands 118 associated with a previous execution block have been fully executed by the deployed drone 108. In this case, an idle execution block 116 may be sent by the drones solution engine 102 to the drones solution edge 106 in response to detecting a request for a new execution block before the execution block is generated. The drones solution edge 106 may then generate drone specific commands 118 based on the idle execution block 116. As one example, the idle execution block 116 may be an execution block 116 that is predefined in advance. For example, the idle execution block 116 may indicate to hover in a same position for a predetermined amount of time and request for another execution block. In various examples, the drones solution edge 106 may include a buffer (not shown) to receive a subsequently generated execution block or a predefined execution block before the previously drone specific commands 118 are executed by the deployed drone 108. In some examples, the drones solution edge 106 may send drone specific commands 118 to the deployed drone 108 as the drones solution edge 106 receives execution blocks. In some examples, the drones solution edge 106 may send drone specific commands 118 to the deployed drone 108 in response to receiving a request for additional drone specific commands 118 from the deployed drone 108.
As one example, a deployed drone 108 may be deployed to scan an area. The deployed drone 108 may have imaging sensors, including thermal imaging sensors, among other sensors. The deployed drone 108 may send sensor data in the form of raw media and events 110 to the drones solution edge 104 to eventually be analyzed by the AI analytics services 106. Based on smart insights 114 from the AI analytics services 106, the drones solution engine 102 generates a number of execution blocks 116 and sends the execution blocks to the drones solution edge 104. In some examples, the execution blocks 116 may be a sequence of predefined execution blocks 116 that are sent to the drones solution edge 104 for execution. For example, the execution blocks 116 may be predefined based on the particular scanning task to be performed. The drones solution edge 104 may generate drone specific commands 118 and sends the drone specific commands 118 to the deployed drone 108. The deployed drone 108 may then execute the drone specific commands 118 and send feedback in the form of raw media and events 110 to the drones solution edge 104. For example, the raw media and events 110 may include all sensor data from the particular area being scanned. For example, the sensor data may include captured images and associated location data. For example, the location data may include data from a global navigation satellite system (GNSS), such as Global Positioning System (GPS) sensor data or any other GNSS. In some examples, the location data may be received from an inertial navigation system (INS). For example, the INS may include a computer, motion sensors and rotation sensors to continuously calculate by dead reckoning the position, the orientation, and the velocity of a moving object without the need for external references.
In various examples, new execution blocks 116 may be generated by the drones solution engine 102 based on smart insights 114 from the AI analytics serves 106 with respect to the raw media and events 110 received from the deployed drone 108. In some examples, the predefined sequence of execution blocks 116 may be modified based on the smart insights 114 from the AI analytics serves 106. For example, the AI analytics services 106 may be visual analytics services that analyze images captured by image sensors of the deployed drone 108. The smart insights 114 may thus be based on the analyzed images and other sensor information from the deployed drone 108. In some examples, the events may include a detected object in one or more images captured by the deployed drone 108. As one example, a crack in a wall may be included in the raw media and events 110 and the deployed drone 108 may receive drone specific commands 118 from the drones solution edge 104 to change position and capture additional images of the wall in order to inspect the detected crack in the wall in greater detail in response to detecting the crack via the smart insights 114. In some examples, an additional AI model may be used in response to the raw media and events 110. For example, an additional AI model may be used to revive additional raw media and events to be used to estimate the width of the detected crack. For example, the additional AI model may be located in either the drones solution edge 104 or the AI analytics services 106. In some examples, a sequential execution block 116 may be generated accordingly to estimate the width of the crack.
As another example, the raw media and events 110 may include thermal imaging with a detected thermal object that may be inspected more closely via the drone specific commands 118. For example, the altitude of the deployed drone 108 may be modified, the angles of the thermal imaging sensor may be modified, etc.
In another example, the deployed drone 108 may be deployed using a predefine sequence of execution blocks used to generate drone specific commands 118 to inspect a parking lot of various cars. The deployed drone 108 may detect a particular car to be inspected. In response to detecting the particular car during execution of a first execution block, the deployed drone 108 may receive drone specific commands 118 to change its operation to inspect the license plate or other features of the car in a second execution block. The deployed drone 108 may then execute drone specific commands 118 corresponding to the second execution block and send additional raw media and events 110 to the drones solution engine 102 via the drones solution edge 104. The deployed drone 108 may execute drone specific commands 118 corresponding to a third execution block 116 by flying to a home position and landing. In various examples, the first and third execution block 116 may have been pre-planned.
In another example, a deployed drone 108 may be deployed as a first aid response. The deployed drone 108 may scan an area and detect persons in danger or laying on the ground. The deployed drone 108 may then dynamically return to the exact location of the detected persons to capture a close video feed of the situation. The deployed drone 108 may then return to a home position afterwards. In this example, the execution blocks 116 generated may include a first execution block 116 that includes taking off and scanning an area. For example, this execution block 116 may have been generated in advance. The first execution block 116 may include receiving media and events concerning people in danger and sending them to the drones solution engine 102. A second execution block 116 may include flying to an identified location of a person in danger and sending a live video feed to a remote control center. For example, the second execution block 116 may be dynamically generated based on smart insights 114 on raw media and events 110 received during execution of the first execution block 116. A third execution block 116 in this example may include flying to a home position and landing. The third execution block 116 may also have been pre-planned rather than based on any smart insights 114 on raw media and events 110.
It is to be understood that the block diagram of
At block 202, media and events are received from a deployed UAV. For example, the media may be raw media, such as images or other sensor data received from any number of sensors in the UAV. In various examples, the events may include detected objects or detected conditions. For example, the UAV may have an edge device with detection capability onboard. In some examples, the media and events may include time stamps. In various examples, raw media and events from the deployed UAV to are filtered to generate the media and the event.
At block 204, the media and the events are sent to an artificial intelligence (AI) service and smart insights are received from the AI service. In some examples, a different AI model may then be selected based the smart insights. For example, the different AI model may be used to generate smart insights from additional media and events received from the deployed UAV.
At block 206, execution blocks are dynamically generated based on the smart insights. For example, the execution blocks may be generated on-the-fly or in real-time in response to receiving the media and events. In some examples, via the processor, a second execution block may be dynamically generated based on media and events received from the execution of vehicle specific commands of a first execution block.
At block 208, the generated execution block is sent to an edge device for generating vehicle specific commands. In some examples, a predefined execution block and sending the predefined execution block to the edge device. For example, the predefined execution block may be generated in advance of dynamically generating the execution block based on the smart insights. In some examples, the predefined execution block may be an idle block that is generated in advance and sent in response to detecting that a dynamically generated execution block has not been generated.

In some scenarios, the techniques described herein may be implemented in a cloud computing environment. As discussed in more detail below in reference to at least
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

In some examples, the AI analytics module 326 can cause a different AI model to be selected for generating additional smart insights in response to the smart insights. The execution block generator module 328 can dynamically generate an execution block based on the smart insights. The execution block generator module 328 can send the generated execution block to an edge device for generating vehicle specific commands. For example, the execution block is to be used to generate vehicle specific commands to be executed on a deployed UAV.
