autoware_ndt_scan_matcher

Purpose

autoware_ndt_scan_matcher is a package for position estimation using the NDT scan matching method.

There are two main functions in this package:

• estimate position by scan matching
• estimate initial position via the ROS service using the Monte Carlo method

One optional function is regularization. Please see the regularization chapter in the back for details. It is disabled by default.

Regularization

Abstract

This is a function that adds the regularization term to the NDT optimization problem as follows.

\[\begin{align} \min_{\mathbf{R},\mathbf{t}} \mathrm{NDT}(\mathbf{R},\mathbf{t}) +\mathrm{scale\ factor}\cdot \left| \mathbf{R}^\top (\mathbf{t_{base}-\mathbf{t}}) \cdot \begin{pmatrix} 1\\ 0\\ 0 \end{pmatrix} \right|^2 \end{align}\]

, where t_base is base position measured by GNSS or other means. NDT(R,t) stands for the pure NDT cost function. The regularization term shifts the optimal solution to the base position in the longitudinal direction of the vehicle. Only errors along the longitudinal direction with respect to the base position are considered; errors along Z-axis and lateral-axis error are not considered.

Although the regularization term has rotation as a parameter, the gradient and hessian associated with it is not computed to stabilize the optimization. Specifically, the gradients are computed as follows.

\[\begin{align} &g_x=\nabla_x \mathrm{NDT}(\mathbf{R},\mathbf{t}) + 2 \mathrm{scale\ factor} \cos\theta_z\cdot e_{\mathrm{longitudinal}} \\ &g_y=\nabla_y \mathrm{NDT}(\mathbf{R},\mathbf{t}) + 2 \mathrm{scale\ factor} \sin\theta_z\cdot e_{\mathrm{longitudinal}} \\ &g_z=\nabla_z \mathrm{NDT}(\mathbf{R},\mathbf{t}) \\ &g_\mathbf{R}=\nabla_\mathbf{R} \mathrm{NDT}(\mathbf{R},\mathbf{t}) \end{align}\]

Regularization is disabled by default. If you wish to use it, please edit the following parameters to enable it.

Where is regularization available

This feature is effective on feature-less roads where GNSS is available, such as

• bridges
• highways
• farm roads

By remapping the base position topic to something other than GNSS, as described below, it can be valid outside of these.

Using other base position

Other than GNSS, you can give other global position topics obtained from magnetic markers, visual markers or etc. if they are available in your environment. (Currently Autoware does not provide a node that gives such pose.) To use your topic for regularization, you need to remap the input_regularization_pose_topic with your topic in ndt_scan_matcher.launch.xml. By default, it is remapped with /sensing/gnss/pose_with_covariance.

Limitations

Since this function determines the base position by linear interpolation from the recently subscribed poses, topics that are published at a low frequency relative to the driving speed cannot be used. Inappropriate linear interpolation may result in bad optimization results.

When using GNSS for base location, the regularization can have negative effects in tunnels, indoors, and near skyscrapers. This is because if the base position is far off from the true value, NDT scan matching may converge to inappropriate optimal position.

Parameters

{{ json_to_markdown(“localization/autoware_ndt_scan_matcher/schema/sub/ndt_regularization.json”) }}

Regularization is disabled by default because GNSS is not always accurate enough to serve the appropriate base position in any scenes.

If the scale_factor is too large, the NDT will be drawn to the base position and scan matching may fail. Conversely, if it is too small, the regularization benefit will be lost.

Note that setting scale_factor to 0 is equivalent to disabling regularization.

Example

The following figures show tested maps.

• The left is a map with enough features that NDT can successfully localize.
• The right is a map with so few features that the NDT cannot localize well.

The following figures show the trajectories estimated on the feature-less map with standard NDT and regularization-enabled NDT, respectively. The color of the trajectory indicates the error (meter) from the reference trajectory, which is computed with the feature-rich map.

• The left figure shows that the pure NDT causes a longitudinal error in the bridge and is not able to recover.
• The right figure shows that the regularization suppresses the longitudinal error.

Dynamic map loading

Autoware supports dynamic map loading feature for ndt_scan_matcher. Using this feature, NDT dynamically requests for the surrounding pointcloud map to pointcloud_map_loader, and then receive and preprocess the map in an online fashion.

Using the feature, ndt_scan_matcher can theoretically handle any large size maps in terms of memory usage. (Note that it is still possible that there exists a limitation due to other factors, e.g. floating-point error)

Parameters

{{ json_to_markdown(“localization/autoware_ndt_scan_matcher/schema/sub/dynamic_map_loading.json”) }}

Notes for dynamic map loading

To use dynamic map loading feature for ndt_scan_matcher, you also need to split the PCD files into grids (recommended size: 20[m] x 20[m])

Note that the dynamic map loading may FAIL if the map is split into two or more large size map (e.g. 1000[m] x 1000[m]). Please provide either of

• one PCD map file
• multiple PCD map files divided into small size (~20[m])

Here is a split PCD map for sample-map-rosbag from Autoware tutorial: sample-map-rosbag_split.zip

Scan matching score based on no ground LiDAR scan

Abstract

This is a function that uses no ground LiDAR scan to estimate the scan matching score. This score can reflect the current localization performance more accurately. related issue.

2D real-time covariance estimation

Abstract

Initially, the covariance of NDT scan matching is a fixed value(FIXED_VALUE mode). So, three modes are provided for 2D covariance (xx, xy, yx, yy) estimation in real time: LAPLACE_APPROXIMATION, MULTI_NDT, and MULTI_NDT_SCORE. LAPLACE_APPROXIMATION calculates the inverse matrix of the XY (2x2) part of the Hessian obtained by NDT scan matching and uses it as the covariance matrix. On the other hand, MULTI_NDT, and MULTI_NDT_SCORE use NDT convergence from multiple initial poses to obtain 2D covariance. Ideally, the arrangement of multiple initial poses is efficiently limited by the Hessian matrix of the NDT score function. In this implementation, the number of initial positions is fixed to simplify the code. To obtain the covariance, MULTI_NDT computes until convergence at each initial position, while MULTI_NDT_SCORE uses the nearest voxel transformation likelihood. The covariance can be seen as error ellipse from ndt_pose_with_covariance setting on rviz2. original paper.

Note that this function may spoil healthy system behavior if it consumes much calculation resources.

Parameters

There are three types in the calculation of 2D covariance in real time.You can select the method by changing covariance_estimation_type. initial_pose_offset_model is rotated around (x,y) = (0,0) in the direction of the first principal component of the Hessian matrix. initial_pose_offset_model_x & initial_pose_offset_model_y must have the same number of elements. In MULTI_NDT_SCORE mode, the scale of the output 2D covariance can be adjusted according to the temperature.
