/visual_slam/status is incorrect ?

[sandeepdutta]

Hello,

I am seeing this message on the launch console . [component_container-1] [WARN] [1707351289.041480251] [visual_slam_node]: Visual tracking is lost but the vo_state field in the status message remains 1. Is there some parameter I should set to enable the status reporting ? Parameters in the visual slam launch file are.

+1 for this. I also would expect the vo_state to report when the IMU is being fused or not. I need to be able to differentiate between a VIO and VO solution.
