CHECK_RS2

#define CHECK_RS2

(

)

Value:

        do {                                                                                                           \

        } while (0)

print_pose

#define print_pose	(		msg,
			pose
	)

Value:

        U_LOG_E(msg " %f %f %f  %f %f %f %f", pose.position.x, pose.position.y, pose.position.z, pose.orientation.x,   \
                pose.orientation.y, pose.orientation.z, pose.orientation.w)
