Exploring LiDAR Technology with GNO-SYS

At GNO-SYS, our LiDAR systems are built to deliver high accuracy distance measurement and topographic mapping capabilities. We engineer custom hardware that includes high-frequency pulse generation, powerful laser emitters, and sensitive receivers. This advanced hardware is paired with robust data capture and processing software, enabling the creation of detailed 3D models of the environment.

Our LiDAR solutions serve diverse applications, from forestry and agriculture to urban planning and disaster management. Whether mapping a forest canopy or designing a cityscape, the precision and adaptability of our systems make them indispensable tools for geospatial professionals.

Behind the Scenes: Developing a Custom LiDAR Solution

At GNO-SYS, we specialize in engineering LiDAR systems that deliver precise distance measurement and topographic mapping. Currently, our team is engaged in an exciting project to develop a custom LiDAR system tailored for a specialized application.

Our development journey begins with an in-depth analysis to select the most suitable hardware components, starting with the core of the system: the laser. High-frequency pulse generation, powerful laser emitters, and sensitive receivers are carefully chosen to ensure optimal performance for the intended application. Our engineers then design and integrate the system components, ensuring seamless operation with our advanced data capture and processing software.

Once the system is assembled, we conduct rigorous bench testing to validate functionality and fine-tune performance under controlled conditions. This allows us to refine the system and address any potential challenges before progressing to operational testing in real-world environments. Our goal is to ensure that the final solution meets, and ideally exceeds, the demands of the application, whether it be forestry, agriculture, urban planning, or disaster management.

 

Case Study: Partners at Any Stage

LiDAR technology has been around for years, with numerous reputable companies manufacturing high-quality systems. At GNO-SYS, we play a critical role in the development process, providing expert calibration and quality assurance to ensure optimal performance.

In November, GNO-SYS collaborated with Lux Modus on a LiDAR sensor calibration project. Despite challenging snowy and icy conditions at Springbank Airport, our team successfully calibrated their system with precision. Sensor calibration is a vital component of the quality assurance process ensuring that even the most advanced LiDAR systems deliver accurate and reliable data.

The Calibration Process:

  1. Setup: We cleared snow to strategically place four reference target poles around the site. Using advanced GPS systems, we obtained precise coordinates for these poles and other identifiable objects, such as fire hydrants, electrical boxes, and building corners.
  2. Data Collection: Lux Modus’ LiDAR system was mounted on a truck and driven repeatedly along a pre-determined path, capturing raw data for calibration.
  3. Analysis: By comparing the point cloud data to the actual coordinates, our team calculated heading, roll, and pitch offset values, fine-tuning the system for optimal accuracy.

Results in Action: 

Through normal usage, even mapping-grade systems can experience slight drifts in offsets and sensor co-registration. Regular calibration is a standard practice to maintain optimal performance and consistency. The final calibrated point cloud demonstrated exceptional alignment with the target poles and surrounding objects, confirming the system’s ability to capture accurate data across diverse environments. For example, convergence plots helped determine the optimal heading offset value, further validating the system’s precision post-calibration. 

Applications of LiDAR: Bringing Data to Life 

LiDAR’s versatility extends far beyond calibration projects like this. Some applications include: 

  • Forestry: Monitoring tree growth and assessing biomass. 
  • Utilities: Assessing infrastructure and vegetation mitigation.  
  • Agriculture: Optimizing irrigation and crop management. 
  • Urban Planning: Creating detailed 3D models for infrastructure design. 
  • Disaster Management: Assessing damage and planning recovery efforts. 

 

Why Choose GNO-SYS for LiDAR? 

Our expertise lies in crafting systems tailored to meet specific project needs, supported by hands-on experience in challenging conditions at any stage of the hardware development process. Whether snow-laden roads or dense urban environments, GNO-SYS delivers cutting-edge solutions backed by precision engineering.

How We Design Custom Systems to Achieve the Best Possible Outcome

Many factors must be closely assessed when designing custom remote sensing systems. Whether using SAR, Optical Imagery, or Near Infrared, each system must align with the specific needs of the client and the data needed. From resolution to data collection to platform integration to budget, the timeline for all factors must be assessed for optimal results.
