Answer

Improving obstacle detection accuracy in a mobile robot using LIDAR and cameras involves integrating sensor data to enhance environmental perception. This process typically involves sensor fusion techniques, which combine LIDAR's precise distance measurements with the rich visual information from cameras.

Access both LIDAR and camera data streams through your robot's middleware, such as ROS/ROS2.
Use a sensor fusion algorithm, like Kalman Filter or Particle Filter, to merge data from LIDAR and cameras, enhancing spatial awareness.
Implement a perception pipeline that includes point cloud processing for LIDAR and image processing for cameras, ensuring synchronized data.
Calibrate the sensors to ensure accurate alignment and transformation between LIDAR and camera coordinate frames.
Test the integrated system in various environments to validate improvements in obstacle detection accuracy.

Additional Comment:

LIDAR provides high-accuracy distance measurements, while cameras offer detailed visual context.
Sensor fusion can mitigate the limitations of each sensor type, such as LIDAR's difficulty with transparent objects or cameras' challenges in low light.
Consider using existing ROS packages like `robot_localization` for sensor fusion and `image_pipeline` for camera processing.
Regular calibration is crucial to maintain accuracy, especially if sensors are subject to mechanical shifts or environmental changes.
