Software Overview

LPX SCAN DESIGNER is a monitoring ﬁeld conﬁguration software developed by SLAMTEC for the LPX series LIDAR sensors. With this software, you can easily conﬁgure the ﬁeld to be monitored, and when the sensor is runnig, the sensor’s built-in monitoring program monitors the conﬁgured ﬁeld without the need for external equipment to process and calculate the LIDAR data. You can also conﬁgure the lidar’s operating parameters, simulate the ﬁeld monitoring program function, and view the device status in LPX SCAN DESIGNER. Before using this software for the ﬁrst time, please make sure to read this document in full to avoid endangering personal safety or causing property damage.

Glossary

Monitor Field / Field

A monitoring ﬁeld refers to an ﬁeld monitored by a sensor. It can contain one or more polygons, circles, sectors, rectangles, etc. A sensor can monitor one or more ﬁelds at the same time. For example, LPX-E3P1 can monitor three ﬁelds at the same time.

Field Set

Field Sets are ﬁelds that sensors monitor simultaneously. An ﬁeld set can contain one or more ﬁelds. When the sensor is working, it will monitor all ﬁelds in an ﬁeld set and output the intrusion status of all ﬁelds in the ﬁeld set.

Monitor Case / Case

The monitoring case is a collection of all status information currently monitored by the sensor. A case contains a ﬁeld set and the corresponding input and output conﬁguration. A sensor can store one or more cases. For example, the LPX-E3P1 can store up to 64 cases. When the sensor is working, the monitoring case can be switched through the external output to adapt to diﬀerent working cases.

Starting

Double-click the installation package and follow the prompts to install. After the installation is complete, double-click the shortcut or SLAMTEC LPX ScanDesigner.exe in the installation directory to start the application. After starting, the program will display the “Overview” interface, where you can see the connected device information and device overview.

Connect to sensor

Refer to the sensor’s operating guide to connect the power and signal cables, and connect the lidar to the computer via the Type-C conﬁguration cable. Click “Connect to Device” in the upper left corner of the interface to automatically refresh the devices available for connection. Select the device to be connected and click “Connect”.

Conﬁg Fields

Select the “Monitoring Field Design” tab in the “Conﬁguration” page on the left. The “Create Design from Template” interface will pop up by default. Select “Simple Conﬁguration” here to continue.

The “Simple Conﬁguration” template provides a ﬁeld set containing two monitoring ﬁelds, which are conﬁgured as “Warning Field” and “Protection Field” respectively. The ﬁeld mon-itoring software provides a variety of monitoring ﬁeld types, and you can freely choose the type of each ﬁeld. The total number of conﬁgurable ﬁeld sets in this software, the number of monitoring ﬁelds contained in a single ﬁeld set, and the conﬁgurable monitoring ﬁeld types are determined by the speciﬁc sensor model. Please refer to the data sheet of the corresponding model device for details, or query in the “Overview” page of this program. This document takes LPX-E3P1 as an example. The sensor supports up to 64 ﬁeld sets, each with three simultaneously monitored monitoring ﬁelds, and each ﬁeld can be conﬁgured as a recognition, warning, or a alarming ﬁeld. The maximum radius of its warning ﬁeld is 10 meters, and the maximum radius of the alarming ﬁeld is 4 meters, and it provides excellent black low-reﬂectivity object monitoring capabilities. Select the preset ﬁeld in the “Field Settings” on the right, and you can see that a circle within the ﬁeld monitoring range is drawn in the preset monitoring ﬁeld, and the sensor will monitor the entire ﬁeld of the circle.

Create Monitor ﬁelds

The software provides the function of drawing polygons, rectangles, circles, and sectors. When drawing a polygon, ﬁrst select “Draw Polygon” in the top toolbar, click the left mouse button to add the ﬁrst point, continue to click the drawing ﬁeld with the left mouse button, and double-click the left mouse button to end the polygon drawing. The software will automatically connect the head and tail of the polygon to form a closed ﬁgure. After completing the polygon creation, left-click to adjust the coordinates of each point of the polygon in the right toolbar, and you can also add and delete points.

When drawing a rectangle, ﬁrst select “Draw Rectangle” in the top toolbar, hold down the left button, drag to a satisfactory size and release the left button to complete the drawing. Similarly, click on the newly drawn shape, and you can adjust the starting point coordinates, length, width, and rotation angle of the rectangle in the toolbar on the right, or you can directly drag and adjust in the ﬁgure.

If you need to draw a circle, select “Draw a circle” in the top toolbar, hold down the left button, drag to a satisfactory size and release the left button to complete the drawing. You can adjust the center coordinates and diameter of the circle in the right toolbar, or you can directly drag and adjust in the ﬁgure.

Drawing a sector is similar to drawing a circle. You can also adjust the starting angle of the sector in the toolbar on the right.

The ﬁnal monitoring range will be clipped according to the maximum range of the monitoring ﬁeld: for graphics that are completely within the monitoring ﬁeld, the ﬁeld inside the graphics and between the graphics and the lidar will be used as the monitoring range; for graphics that are partially within the monitoring ﬁeld, the part outside the monitoring ﬁeld will not be used as the monitoring range; for graphics that are completely outside the monitoring ﬁeld, no related monitoring range will be generated.

Adding Fields and Fieldsets

When no graphics are selected, the toolbar on the right is “Field Settings”, where you can create, delete, or copy ﬁelds or ﬁeld sets.
For the created ﬁelds and ﬁeld sets, you can rename them to easily identify the monitoring purpose of the current ﬁeld or ﬁeld set.
The maximum number of ﬁeld sets that can be created and the number of ﬁelds in each ﬁeld set are limited by the currently connected sensor model. The maximum number of ﬁeld sets will not exceed the maximum number of ﬁeld sets supported by the current sensor model, and the number of ﬁelds in each ﬁeld set will not exceed the maximum number of simultaneously activated ﬁelds supported by the current sensor model.

Draw concentric ﬁelds using associative (mask) mode

In obstacle avoidance cases, it is often necessary to generate cases with diﬀerent ranges based on the same shape. You can use the association (mask) function of this software to draw concentric ﬁelds. First draw the maximum monitoring ﬁeld range in the current ﬁeld, add an ﬁeld to the current ﬁeld set in “Field Settings”, turn on the association (mask) mode below, and select the pre-ﬁll type. The software provides multiple types of circular ﬁlling, forward ﬁlling, and proportional ﬁlling. Select the required ﬁlling type, and then set the ﬁlling distance in the ﬁgure or in the toolbar on the right.

By dragging the newly added ﬁeld, you can change the ﬁeld it is associated with.

You can still draw additional monitoring range graphics in this mode.

Note that the extent of the ﬁeld generated in this way will still not exceed the maximum size of the current ﬁeld mode.

Adjust the position and angle of the sensor

When the center of the drawn graphic is diﬀerent from the actual lidar installation orientation, you can adjust the monitoring ﬁeld with one click by adjusting the direction and position of the lidar.

Select “Edit Lidar Placement Parameters” in the top toolbar or select the lidar in the picture (default is at the coordinate origin), and the lidar’s coordinates, rotation angle, and installation direction (upright or inverted) can be adjusted in the right toolbar. The monitoring ﬁeld in the software will be regenerated with the new orientation of the lidar.

Conﬁg Monitor Case

The monitoring case is the actual output mode of the conﬁgured monitoring ﬁeld, including parameters such as the number of resampling times, output delay, hold time, and output ports corresponding to diﬀerent ﬁelds in the current monitoring ﬁeld. By conﬁguring the monitoring case, you can ﬂexibly control the monitoring signal output parameters you need.
Select “Case Design Conﬁguration” in the left tab to start conﬁguring the monitoring case.

Add and edit Monitor Case

Click “Add New Case” to create a monitoring case. You can also create a new monitoring case by copying an existing monitoring case.

For the monitoring case you created, you can rename it to easily identify the monitoring purpose of the current monitoring case. The instance number corresponds to the number of instances called in the sensor (starting from 0).
The “Multi-sampling” option can adjust the number of resampling. A high number of resampling helps improve the accuracy of monitoring applications, but it also increases the output delay. The “Angular Resolution” option can adjust the monitoring resolution of the instance. Diﬀerent resolutions can adapt to monitoring objects of diﬀerent sizes. “Output Delay” is the delay from the sensor identifying an object within the monitoring range to the output signal; “Output Hold” is the delay from the disappearance of the object to the cancellation of the signal output (in extreme cases, the output signal will be triggered only after the object disappears. At this time, the output signal will be used as the starting point, and the output hold time will be delayed once before stopping the output, that is, the minimum signal hold time). If the currently connected sensor does not support the adjustment of an option, the option will remain ﬁxed and cannot be edited.

On the right, you can bind the ﬁeld set corresponding to the monitoring case. The corresponding order of the ﬁelds in the ﬁeld set and the output ports defaults to the order of arrangement in the ﬁeld set. If you need to change the port corresponding to the ﬁeld, just drag it to the port you want to conﬁgure. If the order of the ﬁelds in the ﬁeld set corresponding to the instance changes, or if an ﬁeld set is added or deleted, a warning symbol will appear at the corresponding position in the current instance. Pay attention to update the current instance.

Upload and download monitoring cases

Upload the newly created monitoring case

Click “Write to Device” on the left to jump to the monitoring case writing interface, as shown below:

The left side is the newly created monitoring case, and the right side is the currently connected device. You can choose whether to use the “Update Mode” to update the monitoring case according to your needs. When writing to the device using the update mode, only the newly designed instance data will be updated without erasing the existing data in the sensor. When the update mode is not used, all the data in the sensor will be erased, and then the monitoring case data to be written will be written.

Load conﬁgured monitoring cases from sensors

Click on the “Stored ﬁeld information” on the left, the software will read all monitoring cases in the sensor and display them in a list.

Click on the monitoring case to be modiﬁed, and click “Import selected to the editor”, you can view the imported case in the “Monitoring ﬁeld design” interface, modify it as needed, and conﬁgure it to an existing or new case in the “Case design conﬁguration”, and then click “Write to device” to write it to the device.

Test monitoring case conﬁguration

After completing the above monitoring case conﬁguration, you can verify its validity as de-scribed in this section. Make sure that the sensor is powered and connected normally. Click “Monitoring ﬁeld design” to switch to the case number corresponding to the current input IO pin, as shown in the ﬁgure below:

Click “Switch to start device measurement preview”, the sensor starts working and outputs real-time point cloud images. At this time, you can move the obstacle to the speciﬁed ﬁeld and observe whether the corresponding output IO or corresponding channel indicator light changes, so as to complete the monitoring case test.
