A quadcopter-based express delivery system, express delivery method and monocular obstacle avoidance method

Abstract

An express transportation system, express transportation method and monocular obstacle avoidance method based on a four-axis aircraft belong to the field of UAV technology application, and specifically relate to an express transportation system, an express transportation method and a monocular obstacle avoidance method based on a four-axis aircraft. . The invention provides an efficient and convenient express transportation system, express transportation method and monocular obstacle avoidance method based on a quadcopter. The invention includes a client mobile phone, a PC management platform, a server and a four-copter aircraft with a C / S architecture. The key structural points of the invention are the GPRS mode for data communication between the PC management platform and the four-copter aircraft. The client mobile phone is used to send express delivery information to the server. The PC management platform is used to send GPS coordinates, customer information, positioning and express delivery information to the quadcopter. The server stores and transfers the express delivery information from the customer's mobile phone and PC management platform.

Description

technical field [0001] The invention belongs to the technical application field of unmanned aerial vehicles, and specifically relates to a four-axis aircraft-based express delivery system, an express delivery method and a monocular obstacle avoidance method. Background technique [0002] UAVs are used in a wide range of fields due to their reliable performance and the ability to complete complex tasks such as investigation, rescue, video surveillance, agricultural pest control, and geological exploration. Among them, the quadcopter, as a multi-axis aircraft, has become a research hotspot today due to its small size, light weight, and portability. Like large unmanned aerial vehicles, it can carry a certain amount of mission load and has the ability to navigate autonomously. [0003] The quadcopter has four inputs and six outputs of an underactuated rotor helicopter, so it can be seen that the system can realize quasi-static flight (circling flight and close-range hovering fl...

AI Technical Summary

Problems solved by technology

[0009] In Australia, Australian drones deliver express delivery. The drone uses a combination of laser ranging and sonar for obstacle avoidance, but it is not equipped with a camera. The cost of obstacle avoidance for laser ranging is high.

[0010] The four-axis aircraft used in the above-mentioned UAV transportation will generate a large amount of real-time data whether it uses the combination of base station and GPS to calculate the path and navigate, or simply uses GPS navigation, or uses the combination of laser ranging and sonar to avoid obstacles. Processor power requirements are high, reducing the processing power of resource-constrained aircraft processors

And neither proposes an effective low-cost obstacle avoidance solution

Most drones are controlled manually, and humans and drones form a system. There is no system-level solution that can directly connect express companies and customers.
