Landing protection
When the aircraft arrives above the return point, the landing protection function will be activated
to detect the ground environment. If the ground is flat, the aircraft will land automatically.
Otherwise it will hover on the spot to wait for the next instruction.
Precise landing
25
When the precise landing function is activated, the aircraft will land as close to the take-off point.
Important
The aircraft will record the take-off point as the default return point. The precise landing can
take effect only when the return point is not refreshed during flight.
Select an open and well-lit area as the take-off point.
When the aircraft is ready for precise landing, it is necessary to ensure that the take-off
environment has no change.
Landing protection and precise landing can be activated with App.
2.1.7 Omnidirectional binocular vision system
The forward, backward, leftward, rightward, upward and downward vision systems of the EVO II
Enterprise use the image data to calculate the distance between the aircraft and the potential
obstacles. Once any obstacle is detected, the system will stop the aircraft. The forward, backward
and downward binocular vision systems also have a Starpoint positioning system. The system
uses an ultrasonic sensor to calculate the height of the aircraft, and at the same time the binocular
camera obtains position information through image analysis.

Remark
Omnidirectional obstacle sensing directions include front, back, up, down, left and right.
However, there are blind spots in the four diagonal directions. In manual flight, attention
should be paid to the surrounding environment and App prompts to guarantee safety.
Do not operate the aircraft in a complex environment where there is insufficient light, small
object (such as twig, line, net), moving object, transparent surface (such as window) or
reflected surface (such as mirror).
In the case of flight with car or other vehicles, please select a field or closed road for driving.
Never use it on highway.
Preconditions
Ensure that the aircraft is in GPS or vision positioning mode.
The aircraft shall take off when the flight LED indicator flashes green slowly or red twice.
When the GPS signal is weak or fails to meet the vision positioning requirement(e.g., when
there are small visible textures on the surface or when the aircraft flies at an altitude of more
than 12 m (36 ft) above sea level), it is necessary to be extremely careful.
The binocular vision sensation system and Starpoint positioning system are affected by the
brightness and texture of the surface below the aircraft. Avoid flying above the following
surfaces:
- Single color
- High reflectivity, such as water surface
- Particularly bright or dark surface
- Surface with frequently changing light
- Surface composed of highly repetitive pattern, such as tile
- Sound absorbing surface, such as thick carpet
- Moving surface, such as road with heavy traffic
The binocular camera lens and sensor shall be kept clean.
In order to avoid disturbing the Starpoint positioning system, do not use 40 kHz ultrasonic
device, such as ultrasonic range finder, fault detector, cleaner or welding machine.
Function description
Intelligent tracking
Intelligent tracking uses deep learning algorithms to detect six types of objects in real time:
pedestrians, cyclists, cars, trucks, boats and animals. Real-time tracking algorithms are used to
automatically track selected objects while avoiding obstacles in flight. This function can use three
modes to track objects.
Pointed flight
Pointed flight allows the user to set the flying direction of the aircraft by touching points on the
screen.
28
Gesture recognition
The main camera uses deep learning algorithms to recognize and respond to three gesture
instructions: straighten your arms up to set yourself as a target, raise your arms to take a photo,
and raise one arm to start or stop recording.
Precise landing
Regarding precise landing, the binocular vision system below the aircraft is used to record the
information at its take-off position. During the return and landing process, the visual algorithm is
used to calculate the position error between the aircraft and its take-off point in real time, so as to
control the aircraft to precisely land at its take-off position.
Safe landing
Regarding the safe landing function, the downward vision system of the aircraft is used to create a
density depth map, and the flatness and angle of the depth map are calculated to detect whether the
surface is flat enough to ensure a safe landing.

Q7. The camera is automatically turned off in the video recording process:
Do not take out the Micro SD card from the camera, but restart the camera and wait that the
video files may be recovered as much as possible.
Q8. The video link is disconnected when the aircraft is not in the range of visibility:
Activate the auto return instruction to return the aircraft to the return point.
Q9. Cautions to use the omnidirectional binocular vision system:
Before flying, make sure that the 12 cameras are clean and free of obstructions.
Omnidirection refers to six directions, including forward, backward, leftward, rightward,
upward and downward.
There is a blind zone of 30º in the four diagonal directions of the aircraft. Please pay attention
to the surrounding environment and the safety instructions of the APP.
Obstacle detection is achieved by detecting the surface texture of the obstacle. In case of no
texture, repeated texture, pure color surface, moving object, tiny object, etc., the detection
function will not be realized normally.
Q10. The precise landing function is not realized normally:
The precise landing function is realized by detecting the texture of the ground when the
aircraft takes off with the binocular camera below.
If there is no texture on the ground, or the camera below is damaged, this function will not be
51
realized normally.
Q11. The omnidirectional binocular vision system cannot work normally:
Restart the aircraft, and check whether it can work normally or not again.
Q12. The video is obliqued during flight:
Horizontally place the aircraft and keep it steady.
Calibrate the gimbal according to the "Gimbal Calibration" function in the APP.
If the problem is still not solved, adjust the gimbal according to the instructions in the
"Gimbal Fine Tuning" function.
Q13. The lens of the binocular camera is stained:
Please wipe the lens with the glasses cloth gently. It is recommended to use the glasses cloth
provided in the packing box.
Q14. Vision errors in the flight process:
Please calibrate the binocular parameters by using the PC calibration tool which can be
downloaded from the official website.
