Holybro PX4FLOW Optical Flow Smart Camera Sonar Kit

The PX4FLOW Sensor utilises a specialised high resolution downward pointing camera, known as an Optical Flow Smart Camera to track ground velocity, along with a Sonar Sensor to measure distance. These two sensors together can provide Autpilots such as the Pixhawk 4 with the ability to position lock when no GPS signal is available, for example indoors. It can also be used in conjunction with the GPS data to provide a more accurate position lock. The sonar sensor can be used to provide a terrain tracking capability.

The Flow Kit has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 250 Hz (bright, outdoors), giving it a very high light sensitive. It also works indoors and in low outdoor light conditions without the need for an illumination LED (at 120 Hz (dark, indoors). The other great feature of this sensor is that it can be re-programmed to do any other low level computer vision tasks using the 752×480 pixel camera and the 168Mhz Cortex M4F CPU.

Features:

• MT9V034 machine vision CMOS sensor with global shutter
• Optical flow processing at 4×4 binned image at 120 (indoor) to 250 Hz (outdoor)
• Superior light sensitivity with 24×24 um super-pixels
• Onboard 16bit gyroscope up to 2000°/s and 780 Hz update rate, default high precision-mode at 500°/s
• Onboard sonar input and mount for Maxbotix sonar sensors. PX4 Flow comes with the sonar already mounted and installed. MB1043
• USB bootloader
• USB serial up to 921600 baud (including live camera view with QGroundControl)
• USB power option

Please Note: The PX4FLOW is supported from Copter 3.3 and higher. It is not yet supported in Plane or Rover.
