1. Connecting to a 3D Scanner
1. Connecting to an INSPIRE 3D Scanner
Here's an example of how to connect to an INSPIRE 3D scanner using a USB cable.
Revopoint INSPIRE 3D scanner can connect to Windows and macOS devices with its 2-meter-long
USB cable.
1.1 USB Cable Connection
Plug into the INSPIRE's Type-C
po!.
Use the Type-A to Type-C
Adapter if there is no Type-A
po!on your PC.
Plug into the PC's USB 3.0 po!.
03
Connect to Revo
Scan via USB or Wi-Fi
on a compatible
Windows, macOS,
Android, or iOS device.

Revopoint INSPIRE 3D scanner can also connect to Windows and macOS devices over Wi-Fi.
1.2 Wi-Fi Connection
Step 1: Power on the 3D scanner.
Power on the 3D Scanner via the *Power Bank Handle or a power outlet.
(Minimum Power requirements: 5V,1A)
*Power Bank Handle sold separately
•Do not plug it into your PC, or it will be in USB
mode by default.
•To use the Wi-Fi connection the scanner must
be powered by a power bank or power outlet.
•When the power indicator turns solid green,
the scanner is successfully powered.
04

•Find the label on the scanner's bottom, and locate the Scanner Model and its SN.
•Go to your Wi-Fi setting, search for the network called: Model + REVO + the !rst eight characters.
For example: INSPIRE-REVO-A2340025
Click the network and wait for it to connect to the PC. (No password is required)
If using the Wi-Fi connection on your PC, please consider the following:
1. Check if your PC has Wi-Fi before connecting the scanner wirelessly. Older desktops may not
suppo!Wi-Fi.
2. Your PC won't have internet access when connected to the scanner's Wi-Fi. Disconnect from the
scanner's Wi-Fi network if you need to go online.
3. If your PC fails to connect to the scanner's Wi-Fi, check if other devices (including mobile devices)
are connected to the scanner or if your PC is linked to another scanner via USB. If none of these
scenarios apply, t#resta!ing the scanner or contact our Customer Se$ice Team for fu!her
assistance.

2.1 How to Use the Tripod
1. Connecting to a 3D Scanner
2. Setting Up a Scan
06
Image 1: Clip the scanner to
the top and extend the tripod's
suppo!legs. Put it onto a desk
for %xed scanning.
Image 3: The tripod can extend
up to 30 cm.
Image 2: Hold the tripod for
handheld scanning.

1) Incorrect Examples
2.2 How to Place an Object (Using the Agrippa Bust as an Example)
Cluttered Background Don't hold the turntable by hand, as the object
will be unstable.
Incorrect Color Scans
- Dim lighting conditions are bad for color
scanning.
Incorrect Color Scans
- Uneven illumination will a&ect texture
mapping.
07
2) Correct Examples
The surroundings are clear of any clutter and
consistently lit.
Using Magic Mat or black bin bag as the
background, and ensuring consistent and even
illumination.

2.3 How to Setup the Scanning Environment
Connect the scanner to a PC
and attach it to its tripod.
Angle the scanner toward the
Agrippa and slightly above it.
Use the Magic Mat or black
bin bag as the background.
The scanner is angled down
towards the object at a
distance of about 25 cm.
Scan Distance
Power on the turntable and
adjust it to its maximum speed.
Put Agrippa on the turntable.
Check the bust to ensure that
there are no shadows on its
su'ace and that the overall
lighting is even and bright.
Note：Working distance of INSPIRE is 250-500 mm.

3.1.1 Standard Accuracy
3.1 Scan Accuracy
1) In Standard Accuracy mode, the post-processing time will be longer, but the results are more
suitable for applications needing more detail.
2) Object Type Suppo!ed in Standard Accuracy Scans
General Object, Dark Object, and Face (Refer to the Object Type section for more details)
3) Advantages and Disadvantages
09
Advantages:
1. High scanning accuracy.
2. Captures much more of the object's details.
Disadvantages:
1. A lower scanning frame rate leads to lower scanning e"ciency.
2. The scanned model takes up a lot of memo#, and post-processing takes a long time.
1) In High-speed(18 fps) mode, the scanning speed can be up to 18 fps and is suitable for scanning
large objects and people.
3.1.2 High-speed(18 fps)

10
2) Object Type Suppo!ed in High-speed(18 fps) Scans
Human, Large Object (Refer to the Object Type section for more details)
3) Advantages and Disadvantages
Check the details of the lower eyelids, mouth corners, hair temples, cochlea, etc, for comparison
between Standard Accuracy and High-speed(18 fps) modes.

High-speed(18 fps)Standard Accuracy
3.1.3 Accuracy Comparison
Advantages:
1. High scanning frame rate for better scanning e"ciency.
2. Uses less memo#and has fast post-processing times.
Disadvantages:
1. Lower accuracy.
2. Less details captured.
3.2.1 Feature Tracking
3.2 Tracking Modes
1) Use Feature Tracking for objects with detailed, distinct su'ace features and no repeating
patterns.

11
3.2.2 Marker Tracking
1) Marker Tracking requires marker stickers placed on or around the object，or place Magic Mat
under the object. Use it for objects that have large )at areas with no distinct su'aces.*At least 5
markers must be in view for each frame during scanning.
2) How does the Feature Tracking Work?
Feature tracking identi%es and tracks an object's distinctive su'ace features. It works by extracting
feature points from the data, matching them across di&erent viewpoints, calculating their
relationships, and using this information to reconstruct a 3D model of the object.

2) What is a 3D Marker?
3D Scanning Marker is a small sticker with a black or white dot printed on it.
3) What's the function of a marker point?
4) How to place marker points?
Marker points work as reference points for the 3D scanner to track, so it knows where the frames
should be stitched.

3.3.1 General Object
13

1) This mode is used to scan objects with a black or dark su'ace, such as black or dark gray clothes,
shoes, black boxes, etc.
2) Objects with Black & Re)ective Su'aces
When scanning an object with a black re)ective su'ace, the high-gloss su'ace needs to be treated
%rst to make it di&used so the scanner can see it. When scanning, increase the exposure of the RGB
and Depth cameras.
3.3.2 Dark Object
14

This encompasses the entirety of the body, from the upper and lower regions to the limbs and hair.
(Apply d#shampoo to scan black hair.)
3.3.4 Body
15
Includes the face and neck.
3.3.3 Face

A scanner's Depth Cameras are infrared cameras that capture the 3D point cloud data. Take care
adjusting the Depth Cameras' exposure as this directly determines the quality of the 3D model
obtained.
This is the Depth Cameras preview window. It shows if an
object is underexposed or overexposed with the current
exposure settings.
Displays the exposure setting slider and exposure value.
Drag the slider bar to decrease or increase the exposure.
Red areas: Overexposed
Blue areas: Underexposed

1. Connecting to a 3D Scanner4. Depth and RGB Cameras' Exposure Settings
4.1 Depth Camera
This mode is for scanning objects that are equal to or larger than the size of a human body. The
object's main physical features and shapes are captured in this mode at a fast scanning speed.
3.3.5 Large Object

17
Correct Exposure Underexposed Overexposed
The RGB camera captures the object's color information during a scan. In the RGB Camera window,
you can see if the object is overexposed or underexposed.
4.2 RGB Camera
The blue crosshair can be used as a reference to aim at
the object to avoid it being out of frame.
Displays the exposure setting slider and exposure value.
Drag the slider bar to decrease or increase the exposure.
RGB Exposure Guidelines
Exposure Guidelines
Correct Exposure :
No obvious blue and red areas
on the object, and the details
are clear.
Underexposed :
Large blue areas on the object
and some details can't be seen,
so the exposure value needs to
be increased.
Overexposed :
Large red areas on the object
and some details can't be seen,
so the exposure value needs to
be decreased.

Shown in Red
Red indicates tracking lost. When a "Tracking
Lost" warning is displayed, re-target the scanner
to a previously scanned area (blue) and keep it
still for several seconds so that the scanner can
re-acquire tracking. When the red po!ion of the
display changes to green, scanning can resume.
Shown in Yellow
Yellow indicates the captured data is aligning. If
the yellow is shown for only a sho!time,
continue to capture data. If it doesn't disappear,
