Hi,  
I’m trying to implement **Collision Prevention** with Pixhawk 2.4.8 with **px4 1.11.1** firmware flashed in it. I’m using **realsense d435i** camera with **j\*\*\*\*etson nano**.[[Collision Prevention | PX4 User Guide](https://docs.px4.io/main/en/computer_vision/collision_prevention.html#companion)] as mentioned here i have changed all the param required but QGC mavlink inspector isn’t showing Obstacle Distance data. I am unable to find the exact issue. Please help
