Deep Learning Based Real-time Object Detector for DJI Drones

https://www.youtube.com/watch?v=WSf7hw8HY1g

This project involves real-time object detection for DJI drones from the ground station using TensorFlow Object Detection API. The TensorFlow Object Detection API is an open source framework built on top of TensorFlow making it easier to construct, train and deploy object detection models. This results in machine learning models capable of localizing and identifying multiple objects in images streaming from DJI drones to the ground station with more computational power.

The ground station code is available at the GitHub repo to apply object detection for streaming videos from DJI drones.

Requirements

Configuration at DJI GO

  1. General Settings -> Select Live Broadcasting Platform -> Customer 
  • rtmp://<ip address>/live/djidrone
  • Be sure to substitute the IP address of your computer running docker for <ip address>

Command at the Ground Station

  1. python object_detection_multithreading.py --source=1 --width=1280 --height=720
  2. python object_detection_multithreadng.py Optional arguments (default value):
  • Device index of the camera --source=0
  • Width of the frames in the video stream --width=480
  • Height of the frames in the video stream --height=360
  • Number of workers --num-workers=2
  • Size of the queue --queue-size=5

Thanks

Special thanks to  our sponsors and team members. It was a really cool endeavor and an unforgettable experience that is almost impossible to get anywhere else

The What, Why, and How of Protecting Your Drones

Drone protection is essential for those who do not want their investment in this expensive technology to go to waste. Therefore, there are a few critical areas in which drone owners can make sure their drones will last as long as the owner expects and be an enjoyable experience.

Safely transporting the drone by choosing the right equipment to prevent drone damage and purchasing a case and drone supplies are both critical for ensuring the proper protection of a drone.

Safe Battery Use

To prepare a drone for safe transportation, especially on an aircraft, the battery level should be about 35-50 percent due to the increased fire risk and their susceptibility to damage. The terminals of the batteries should also be protected from short circuit by using adhesive strips or films.

Since lithium batteries are at risk of spontaneous combustion, packing the batteries in a LiPo safe bag means it will be fireproof during transportation, and there will also be not as many problems while at the security checkpoint. Additionally, it is essential to make sure the lithium batteries can be put in a carry-on bag, and since these batteries are quite large, using a carry-on bag that is large enough to fit backup batteries.

Using a Carrying Case

A quality carrying case is essential for drone protection. A hard-shell case will not only protect the drone from damage, but it will also make it easier to carry around with no worry. Many people who choose to use a garment bag that is carried over the shoulder put their drones at risk since there is no hard protection.

A hard-shell case also provides the drone owner with slots that fit the drone perfectly into a secure place in which it cannot move. Drone users will find that an investment in a hard-shell carrying case is worth the investment as it will provide extra drone protection.

Overall, using a drone comes with the responsibilities of ensuring that it will be protected while the owner wishes to transport it. Investing in equipment, such as a fireproof battery case and a hard-shell carrying case will eliminate much of the risks associated with potential damage to the drone and its batteries. It is also a matter of convenience for the user to transport the drone and equipment in cases that are specially designed for it. For anyone wanting to use their drone in travel photography, taking the proper precautions is a must.

New Report Benchmarks Drone Industry and Refutes Hyperbole

We just released the results of our third annual drone industry benchmark survey and it’s a kicker.

The 2018 Drone Market Sector Report examines worldwide drone sales, service providers, business and public agency users, and software services. This independent research, which is sponsored by DJI, DroneDeploy, DroneInsurance.com, and Trimble, finds a growing demand for businesses to use drone-acquired data in their day-to-day operations as well as other fresh insights on major drone industry segments.

Research

Our online market survey garnered over 2,500 respondents representing over 60 industries worldwide. Our analysis yields 10 key insights that summarize the current state of the industry, plus detailed analysis of drone adoption by businesses and enterprises.

Report

The 107-page report presents the results and analyses from each survey question. It’s organized to match our survey, with four sections that correspond to the four major segments of the drone industry:

  1. Drone aircraft and payloads purchased
  2. Service providers that offer drone-based imaging or sensing services for outside hire or sale
  3. Businesses and public agencies with drone programs
  4. Software apps or online services for drone operations and imaging

The report features more than 60 helpful figures and tables and offering insight and analysis on:

  • Who’s buying what types of drones from which makers at what prices and for what uses.
  • How large the drone-based service providers are, and how they position themselves to their target industries.
  • Who the business users of drone-based projects are, and which industries have traction.
  • How much service providers, business users, and public agencies are using flight management, mission planning, and image processing software for drone-based projects.

Findings

Among the more interesting findings are that commercial drone fleet sizes are smaller than most people think. If you believe the hyperbole, there are hundreds of thousands of drones in the airspace at the same time, but the survey finds that the average commercial user has just two drones that are only flying two projects a month and most of those flights consume less than flight three hours.

There are many other insights in the report, but these three are especially worth highlighting:

  • Professional use of drones is growing. We find that almost three-quarters of all drones weighing over 250 grams are purchased for professional purposes—either governmental or business. This is up from last year.
  • DJI continues to dominate the market and has made gains this year in every category from drone aircraft at all price ranges, to add-on payloads, to software. Survey data shows DJI is still the dominant brand for drone aircraft purchases, with a 74% global market share in sales across all price points.
  • Most businesses and public agencies are new to drones, have small programs, and perform their own services. The survey finds that nearly three-quarters of businesses or public agencies have only had a drone program in place for two or fewer years.
