New Firmware Release for the Matrice 4 Series

Here is everything you need to know about the DJI Matrice 4 Series's new firmware update

By DJI EnterpriseJune 10, 20255 min readRegulations

DJI Matrice 4 Series releases new firmware that supports manual flight with real-time terrain following, intelligent detection with adjustable confidence levels, and enhanced features for spotlight and speaker.

On April 15th, this flagship flight platform received a new firmware upgrade, adding a number of practical functions and once again elevating its operational potential.

Manual Flight with Real-time Terrain Follow

This feature enables the aircraft to dynamically adjust its altitude during manual flight based on real-time terrain data collected by the downward vision sensors. Maintaining a consistent relative altitude above ground, it ensures safe and stable operations even in complex or uneven terrain.

  • Maintains consistent Above Ground Level (AGL) altitude
  • Temporary altitude adjustment with control stick
  • Returns to preset AGL after stick release
  • Combines with Cruise Mode and Add Point for efficient missions
Notes: Supported AGL: 30-200m. Requires sufficient lighting and clear ground textures. Not supported at night, in fog, over water, snow, or textureless terrain.
Terrain Follow ExampleReal-time terrain-follow in action

Intelligent Recognition with Adjustable Confidence Threshold

Set custom confidence levels for intelligent recognition, with presets for target counting and search. The confidence value (0-1) indicates certainty about a target in the detection box.

  • High Confidence (e.g., 75%): Precise target localization, ideal for counting
  • Low Confidence (e.g., 35%): Higher sensitivity, ideal for search
Confidence Threshold ExampleConfidence threshold setting in DJI Pilot 2

Cruise Control Fine-tune via C4 Dial

After enabling Cruise Control, flight speed can be finely adjusted in 0.1 m/s increments using the C4 dial. This allows for more convenient and precise speed adjustments, reducing operator workload in large-scale operations.

Spotlight and Speaker Function Upgrades

The DJI AL1 Spotlight now supports multiple strobe modes, and the AS1 Speaker supports multiple languages.

  • Spotlight Strobe Modes: Slow, Fast, Alternating
  • Speaker Languages: Mandarin, English, Korean, Japanese, French, Spanish
