Acquire Data
The laser profiler obtains data by scanning the object line by line. A raw image is acquired as each
line is scanned. A single pixel is extracted from each column of pixels in the raw image, and this
pixel is called a spot. Spots make up a profile. Finally, the profiles of many lines are combined to
generate the intensity image, depth map, and point cloud.
Mech-Eye Viewer provides two data acquisition modes:
•Profile Mode: Adjust the parameters relevant to the profile to obtain the satisfactory profile.
•Scan Mode: Adjust the parameters relevant to the images and point cloud to obtain the
satisfactory intensity image, depth map, and point cloud.
Example Scenario
The following content is based on this example scenario:
•Data acquisition is triggered by Mech-Eye Viewer.
•The scan of each line is triggered by the encoder.
•The target object moves in one direction relative to the laser profiler.
•The target object is a metal block, and the dimensions are about 80 × 35 × 8 mm.
Obtain the Profile
Follow these steps to obtain the satisfactory profile:
1. Click to acquire the raw image once.
2. Click on the data types below the scan buttons to switch between the raw image and profile.
◦Raw image: used to adjust the brightness of the laser line.
◦Profile: Used to check the profile extraction result, such as the gaps in the profile.
3. Determine if the brightness of the laser line in the raw image meet the requirement: The
grayscale values of the pixels at the center of the laser line should be between 200 and 255.

Too dark
Good
Too bright
In the lower-right corner of the raw image, you can check the grayscale value of the pixel
where the cursor is located. If not displayed, please check the Image Information Box
option in the View menu.
4. If the brightness of the laser line does not meet the requirement, please adjust the following
parameters in the Parameters tab on the right.
The metal block is made of a single material. Therefore, in the Brightness Settings category,
select Timed for the Exposure Mode parameter. Now, adjusting the Exposure Time parameter
will change the brightness of the laser line in the raw image.
a. Adjust the Exposure Time parameter based on the brightness of the laser line.
▪If the laser line is too dark, increase the value of the Exposure Time parameter.
▪If the laser line is too bright, decrease the value of the Exposure Time parameter.
b. Acquire the raw image again, and check the brightness of the laser line. If needed, keep
adjusting the parameter until the brightness of the laser line meets the requirement.
If the target object is made of multiple materials or has multiple colors, you can use
the HDR exposure mode. For more information, please refer to Exposure Mode.
5. Click Profile below the acquisition buttons to check the quality of the profile.
The profile should be mostly complete without gaps.

If the profile quality is not good, please adjust the brightness of the laser line in the raw
image again.
Obtain Intensity Image, Depth Map, and Point Cloud
The profile obtained in the profile mode is the foundation for generating the intensity image, depth
map, and point cloud.
After the profile meets the requirement, follow these steps to obtain the intensity image, depth
map, and point cloud.
1. Click [ Scan Mode ]in the upper right of the interface to switch to the scan mode.
2. Set the parameters relevant to scan triggering based on the actual scenario:
◦When the data acquisition is triggered by Mech-Eye Viewer, set the Data Acquisition
Trigger Source parameter in the Trigger Settings category to Software.
◦When the scanning of each line is triggered by the encoder, set the Line Scan Trigger
Source parameter in the Trigger Settings category to Encoder.
◦When the target object moves in one direction relative to the laser profiler, set the Trigger
Direction parameter to Channel A leading or Channel B leading based on the actual output
signals of the encoder.
3. Click . The laser profiler will complete the current round of data acquisition based on the set
value of the Scan Line Count parameter, and generate the intensity image, depth map, and
point cloud.
4. Click the data types below the acquisition buttons to view the intensity image, depth map, and
point cloud.
For more information on image capturing and data types, please refer to Acquire and
View Data.
5. Determine the data quality.
In the intensity image, depth map and point cloud, the data corresponding to the target object
should be complete. Refer to the following table for examples of good-quality data.

Adjust Parameters
If the obtained data is not complete, please refer to the following example and adjust the Scan Line
Count parameter in the Scan Settings category:
1. Set the Scan Line Count parameter to 2000 and acquire data again. Check the intensity image.
The metal block in the intensity image is not complete.
2. Based on the proportion of the metal block that was scanned, estimate and set the value of the
Scan Line Count parameter to 6000. Then, acquire data again. Check the intensity image. The
metal block in the intensity image is complete now.
This scenario does not take into account the aspect ratio of the target object in the scan data.
If you need the aspect ratio of the target object in the scan data to match that of the actual
object, please adjust Trigger Signal Counting Mode and Trigger Interval.
Use Data
The intensity image, depth map and point cloud obtained through Mech-Eye Viewer can be saved
locally or can be output to Mech-Vision or third-party machine vision software for subsequent
