scaning error for Laser Scan Matcher [closed]

edit

Hello,

I am using ZED camera and the wheel odometry, fused together with robot_localization. My code uses laser_scan_matcher with gmapping to build the map of the environment. I am using deptimage_to_laserscan to convert 3D point cloud to 2D laser scan.

    <launch>

<!--EKF Launch -->
<include file="$(find robot_localization)/launch/EKF_Odom.launch" />

<!--Zed Camera Launch -->
<include file="$(find zed_wrapper)/launch/zed.launch" />

<arg name="base_frame"              default="zed_camera_center"/>

        <param name="range_max" value="60"/>
        <remap from="image" to="/zed/depth/depth_registered"/>

</launch>

This is my launch file. When I launch it I get error:

[ WARN] [1552782652.945326528]: Laser has to be mounted planar! Z-coordinate has to be 1 or -1, but gave: 1.14000
  icp_loop: failed: after trimming, only 51 correspondences.
icp: ICP failed for some reason.

[ WARN] [1552782652.978282773]: Laser has to be mounted planar! Z-coordinate has to be 1 or -1, but gave: 1.14000

Any idea how I can fix this? Any suggestions are appreciated.

Thanks, Hdbot
