Challenges of Using LiDAR in Coal Mining 1. Surface Reflectivity: Black objects (coal body) tend to absorb more light than they reflect, which can reduce the effectiveness of LiDAR detection. High frequencies like 240 kHz can help improve resolution and detail, but they do not completely solve the issue of low reflectivity. 2. Measurement Noise: LiDAR sensors can be affected by noise, which can reduce the accuracy of the data collected 3. Range Limitation: The effective range of LiDAR sensors can be limited, especially in large-scale mining operations 4. Environmental Occlusion: water body, vegetation, and other structures can leading to incomplete data 5. Feature Degradation: The complex and irregular surfaces in mining environments can degrade the quality of the LiDAR data This snapshot is an example of a LiDAR survey in coal mining that did not take into account the capabilities of the sensor and a good flight plan. There are gaps in the data. So, what best practice to do Lidar survey in coal mining? I will share it in the next post...... stay linked in #tetaproduktif #dronelidar #aerialmapping #mining #coalmining #lidar

What kind of IMU did you use?
Interesting, but have you tried with 500 kHz pulse repetition rate?
