3D Sensing and Vision System 
Spark is equipped with a 3D Sensing System 1, consisting of a 3D infrared module at the front of the air-
craft, which scan for obstacles during flight.
The main components of the Vision System are located on the underside of\
 the aircraft body. This in-
cludes a camera 2 and a 3D infrared module 3. The Vision System uses 3D infrared module and image 
data to help the aircraft maintain its current position, enabling precis\
ion hovering indoors or in environ-
ments where GPS signal is not available. 
The 3D Sensing System constantly scan for obstacles, allowing Spark to a\
void obstacles when lighting is 
sufficient.

Detection Range
The detection range of the 3D Sensing System is depicted below. Note tha\
t the aircraft cannot sense or 
avoid obstacles that are not within the detection range.
Using the Vision System
The Vision System is activated automatically when the aircraft is turned\
 on. No  further  action  is required. 
The Vision System can be used in indoor environments where GPS is unavai\
lable. Using the Vision 
System, the aircraft can hover precisely, even without GPS.

Follow the steps below to use the Vision System:
1.  Ensure  the  aircraft  is  in  P  Mode  and  place  the  aircraft  on  a  flat  surface.  Note  that  the  Vision  System 
cannot work properly on surfaces without clear pattern variations. 
2.  Turn  on  the  aircraft.  The  aircraft  will  hover  in  place  after  takeoff.  The  aircraft  status  indicators  will  flash 
green twice, which indicates the Vision System is working.
Powered by the 3D Sensing System, the aircraft is able to actively brake\
 when obstacles are detected in 
front. The 3D Sensing System works best when lighting is adequate and th\
e obstacle is clearly marked or 
textured. The aircraft must fly at no more than 6.7 mph (10.8 kph) to allow for sufficient braking distance.
3D Sensing and Vision System performance are affected by the type of surface being flown over. 
The aircraft will switch from P Mode to ATTI Mode automatically if neith\
er GPS or Vision System 
are available. Please be vigilant when operating Spark in the following \
situations:
 Flying at high speeds below 0.5 meters.
 Flying over monochrome surfaces (e.g., solid black, solid white, solid red, or solid green).
 Flying over highly reflective surfaces.
 Flying over water or transparent surfaces.
 Flying over moving surfaces or objects.
 Flying in an area where the lighting changes frequently or drastically.\
 Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
 Flying over surfaces without clear patterns or texture.
 Flying over surfaces with identical repeating patterns or textures (e.g., tiling).
 Flying over small and fine objects (e.g. tree branches and power lines).
 Flying at speeds of over 6.7 mph (10.8 kph) at 2 meters above the ground.
 Keep sensors clean at all times. Dirt or other debris may adversely affe\
ct their effectiveness.

Return-to-Home (RTH)
The Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There are
three types of RTH: Smart RTH, Low-Battery RTH, and Failsafe RTH. This following section describes the
three RTH scenarios in detail.
GPSDescription
Home Point
If a strong GPS signal was acquired before takeoff, the Home Point is 
the location from which the aircraft launched. The GPS signal strength 
is  indicated  by  the  GPS  icon  (   ).  The  aircraft  status  indicator  will 
blink rapidly when the home point is recorded.  
Low-Battery RTH
Low-Battery RTH is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect 
the safe return of the aircraft. Users are advised to return home or lan\
d the aircraft immediately when 
prompted.  DJI  GO  4  will  display  a  notice  when  a  low-battery  warning  is  triggered.  If  no  action  is  taken 
after the 10-second warning, the aircraft will automatically return to the Home Point. The user can cancel 
the RTH procedure by pressing the RTH button or Flight Pause button on the remote controller. The 
thresholds for these warnings are automatically determined based on the \
aircraft’s current altitude and 
distance from the Home Point. Low-Battery RTH will only appear one time during flight.
The aircraft will land automatically if the current battery level can on\
ly support the aircraft long enough to 
descend from its current altitude. 
The Battery Level Indicator is displayed in DJI GO 4, and is described b\
elow:
Smart RTH
Initiate Smart RTH when GPS is available. Tap the RTH button in DJI GO 4\
 and follow the onscreen 
instructions. The user can also immediately exit Smart RTH by pressing t\
he Stop icon × in DJI GO 4.
Pressing and holding the RTH button on the remote controller can also initiate Smart RTH. Press it again 
to exit.

N/AN/AN/A
 When the Critical Low Battery level warning is triggered and the aircra\
ft begins to land 
automatically, throttle up using the virtual joysticks or control sticks to keep the aircraft at 
its current altitude. This gives you an opportunity to navigate to a more appropriate landing 
location.
  The  colored  zones  and  markers  on  the  battery  level  indicator  bar  reflect  the  estimated 
remaining  flight  time.  They  are  automatically  adjusted  according  to  the  aircraft’s  current 
location and status.
Failsafe RTH
If the Home Point was successfully recorded, GPS signal is strong and th\
e compass is functioning 
normally, Failsafe RTH will be automatically activated if the wireless signal is lost for a specified amount of 
time (three seconds when using the remote controller and 20 seconds when using Wi-Fi). The user may 
cancel Failsafe RTH to regain control when the wireless signal connectio\
n is reestablished.
RTH Procedure
1. Home Point is recorded automatically. 
2. RTH procedure is triggered i.e., Smart RTH, Low-Battery RTH and Failsafe RTH.
3. Home Point is confirmed and the aircraft adjusts its orientation. 
4. a. The aircraft will ascend to the pre-set RTH attitude and then fly to the Home Point when the aircraft is 
further than 20 m from the home point.
b. When the aircraft is between 3 m and 20 m from the Home Point, it wil\
l return to the Home Point at 
the current altitude with the RTH at Current Altitude option enabled (the default setting in DJI GO 4) if 
flying at or above 2.5 m. It will ascend to 2.5 m then return to home if flying lower than 2.5 m.

Obstacle Avoidance during RTH
Spark will Return to Home at a flight speed of 10 m/s and cannot avoid obstacles when RTH is triggered and 
the aircraft is further than 100 m from the home point.
Spark can sense and actively attempt to avoid obstacles during RTH, prov\
ided that lighting conditions are 
adequate enough for the 3D Sensing System and RTH is triggered when the \
aircraft is less than 100 m from 
the Home Point. Upon detecting an obstacle, the aircraft will act as fol\
lows:
1. The aircraft decelerates when an obstacle is sensed at 16 ft (5 m).
2. The aircraft stops and hovers then starts flying backward until the 3D Sensing System cannot sense any 
obstacles. 
3. The aircraft ascends vertically for about five seconds. 
4. RTH procedure resumes. The aircraft will continue flying to the Home Point at the current altitude.
 The aircraft cannot return to the Home Point when GPS signal is weak or\
 unavailable.
 It is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app, tap 
“GO FLY” and tap  to set the Failsafe Altitude.
 The aircraft will stop ascending and immediately return to the Home Poin\
t if you move the 
throttle stick in the aircraft reaches 65 feet (20 meters) altitudes or beyond during Failsafe.

 Obstacle sensing will turn off and the aircraft will ascend to the Fail\
safe altitude automatically 
and will fly to the Home Point at a flight speed of 10 m/s if the obstacle can still be sensed after 
the aircraft has flown backward for 10 m.
 The aircraft will repeat steps 1-3 if the obstacle is sensed again during ascent. 
 The aircraft cannot avoid obstacles above, beside, or behind the aircra\
ft.
 Precision Landing performance is subject to the following conditions:
a. Home Point is recorded upon take off, and cannot not be refreshed during flight.
b. The aircraft must take off vertically. Takeoff altitude must be greater than seven meters.
c. Home Point terrain features remain largely unchanged.
d. Home Point terrain with no distinctive features will affect performance.
e. Lighting conditions cannot be too light or too dark. The following actions are available during landing:
a. Throttle down to accelerate landing.
b. Moving the control sticks in any other direction will stop Precision Landing. Spark will descend 
vertically after the control sticks are released.
Precision Landing
Spark  automatically  scans  and  attempts  to  match  the  terrain  features  underneath  it  during  Return-to- 
Home. When the current terrain matches Home Point terrain, Spark will be\
gin landing immediately to 
achieve precision landing. DJI GO 4 will show a terrain feature mismatch\
 prompt if matching fails.
Intelligent Flight Modes
Spark supports Intelligent Flight Modes, including QuickShot, ActiveTrack, TapFly, Gesture, and Tripod 
Mode. Tap  in DJI GO 4 or press the Function button on the remote controller to en\
able an Intelligent 
Flight Mode.
QuickShot
QuickShot shooting modes include Rocket, Dronie, Circle, and Helix. Spark will record a video according 
to  the  selected  shooting  mode  and  then  automatically  generate  a  10-second  short  video.  The  video  can 
then be viewed, edited, or shared to social media from the Playback menu\
. 
 Dronie : Fly backward and upward, with the camera locked on your subject\
.
  Circle: Circle around your subject.
  Helix: Fly upward, spiraling around your subject.
   Rocket: Ascend with the camera pointing downward.
