DJI Mavic Pro

Overview:

Compact

The DJI Mavic Pro is a small yet powerful drone that turns the sky into your creative canvas easily and without worry, helping you make every moment an aerial moment. Its compact size hides a high degree of complexity that makes it one of DJI’s most sophisticated flying cameras ever. 24 high-performance computing cores, an all-new transmission system with a 4.3mi (7km) *range,5 vision sensors, and a 4K camera stabilized by a 3-axis mechanical gimbal, are at your command with just a push of your thumb or a tap of your finger.

No Bumps and Scrapes

Ultrasonic waves and Time of Flight (ToF) sensors are often used to measure distance from an obstacle, but both methods calculate distance based on signal reflection and are therefore reliant on the shape of the obstacle. This means distances from common obstacles such as rocks and branches cannot be sensed. Flight Autonomy gives the Mavic long range, high precision obstacle sensing, enabling it to scan its environment in 3D before taking off. Flight Autonomy ensures the Mavic precisely locates obstacles around it.

Detecting obstacles requires getting information about the obstacle to the Mavic. Ultrasonic and ToF sensors measure distance by detecting the first reflected wave. In other words, they can only measure the distance from a single point, instead of getting a 3D depth image of a particular obstacle. Another method of creating a depth image is structured light projection. For this, a structured light sensor projects infrared in a specific shape onto the obstacle in front of it. The infrared then reflects back and the sensor then calculates the strength of the reflected signal so that it can create a 3D depth image of the obstacle. However, due to the limited strength of infrared and interference from visible light, the maximum sensing distance for a structured light sensor is only 3 to 5 meters. It is also ineffective in bright light significantly reducing its reliability and effectiveness on a sunny day.

Flight Autonomy is made up of 7 components including 5 cameras (forward and downward dual vision sensors and the main camera), dual-band satellite positioning (GPS and GLONASS), 2 ultrasonic rangefinders, redundant sensors, and a group of 24 powerful, specialized computing cores. Cameras on the left and right side in the front of the Mavic are fixed in place using an aluminum bracket to ensure the optimum alignment of the vision sensor lenses.

As the Mavic flies, dual forward and downward vision sensors measure the distance between itself and obstacles by taking photos from all four cameras and using the information to create a 3D map that tells it exactly where obstacles are. The dual forward and downward vision sensors require visible light to function, and in bright light can see as far as 49ft (15m) out in front.

This obstacle avoidance system is activated in every Intelligent Flight Mode including all Active Track modes, Tap Fly and Terrain Follow. It is also available during automatic Return to Home, so that the Mavic can easily make its way back without bumping into anything in its path.
