On September 27, DJI's "Royal" Mavic drone was officially released. According to reports, the foldable design of this drone, the degree of intelligence greatly improved.Mavic brings together DJI core technology design, foldable body, built-in 24 high-performance computing kernel, 7km high-definition mapping, visual and ultrasonic environment perception system, 4K high-performance aerial camera, etc., so that the user is lightly loaded, enjoy the fun of flying.
In the human-computer interaction, the intelligent visual technology allows "Mavic" to realize "pointing flight", touching the screen of the cell phone, it can be converted into the direction of the command, flying in the selected direction and in the whole process, it can realize automatic obstacle avoidance and precise hovering flight. Mavic is equipped with the FlightAutonomy system to realize automatic obstacle avoidance and precise hovering flight, through the five-eye vision, GPS/GLONASS dual-mode satellite positioning system, ultrasonic module, sensor redundancy and 24 high-performance computing kernel fusion real-time distance detection of obstacles, and timely and accurate braking and hovering or go-around action. Obstacle perception and distance measurement is an important part in realizing automatic obstacle avoidance and precise hovering flight, which is mainly realized by ultrasonic, TOF and other sensors. At present, the ultrasonic sensor provided by Audiowell for Mavic UAV is mainly used to measure the relative height between the vehicle and the bottom.
Ultrasonic sensors are sensors that use ultrasonic waves as receiving or transmitting signals with high frequency, short wavelength, small diffraction, good directionality, etc. They also have good penetrability in liquids and solids, and are not affected by dust in the air or electromagnetic fields, or by the color and temperature of the solid surface.
At present, the ultrasonic sensors developed and produced by Guangdong Audiowell Sensing Technology Co., Ltd. are in the leading position in the market, and have been widely used in intelligent robot obstacle avoidance, UAV obstacle avoidance, automotive electronic distance measurement and other systems. Audiowell and according to the market demand launched the application program - ultrasonic distance measurement module.
Product features:
- Fast response speed (<5ms)
- High measurement accuracy (±10mm)
- Strong anti-interference ability, good directionality
