 <p>This document outlines the high-level design strategies, goals and related rationales in the development of the Perception Component. Through this document, it is expected that all OSS developers will comprehend the design philosophy, goals and constraints under which the Perception Component is designed, and participate seamlessly in the development.</p>

 <h2 id="overview">Overview<a class="headerlink" href="#overview" title="Permanent link">#</a></h2>
 <p>The Perception Component receives inputs from Sensing, Localization, and Map components, and adds semantic information (e.g., Object Recognition, Obstacle Segmentation, Traffic Light Recognition, Occupancy Grid Map), which is then passed on to Planning Component. This component design follows the overarching philosophy of Autoware, defined as the <a href="https://autowarefoundation.github.io/autoware-documentation/main/design/autoware-concepts/">microautonomy concept</a>.</p>
 <h2 id="goals-and-non-goals">Goals and non-goals<a class="headerlink" href="#goals-and-non-goals" title="Permanent link">#</a></h2>
 <p>The role of the Perception component is to recognize the surrounding environment based on the data obtained through Sensing and acquire sufficient information (such as the presence of dynamic objects, stationary obstacles, blind spots, and traffic signal information) to enable autonomous driving.</p>
-<!-- Perception コンポーネントの役割は、Sensingで得られたデータを基に、周囲の環境を認識し、自動走行を実現するために充分な情報（たとえば、周囲の動物体や、静止障害物、死角、信号機の情報）を得ることです。 -->

 <p>In our overall design, we emphasize the concept of <a href="https://autowarefoundation.github.io/autoware-documentation/main/design/autoware-concepts">microautonomy architecture</a>. This term refers to a design approach that focuses on the proper modularization of functions, clear definition of interfaces between these modules, and as a result, high expandability of the system. Given this context, the goal of the Perception component is set not to solve every conceivable complex use case (although we do aim to support basic ones), but rather to provide a platform that can be customized to the user's needs and can facilitate the development of additional features.</p>
-<!-- Perceptionの全体設計において、我々は [microautonomy architecture](https://autowarefoundation.github.io/autoware-documentation/main/design/autoware-concepts) の概念を重視しています。microautonomy とは、適切な機能のモジュール化やインターフェースの明確な定義に基づき、システムの高い拡張性を焦点を当てた設計コンセプトです。そのため Planning component の目標は、すべての考えられる複雑なユースケースを解決することではなく（基本的なものはサポートすることを目指していますが）、ユーザーのニーズに合わせてカスタマイズでき、第三者によって機能が容易に追加可能なプラットフォームを提供することに設定されています。 -->

To address this challenge, we will discuss methods for conducting detailed performance measurements for Autoware and provide case studies.

For example, when we plot <code>minor-faults</code> on the horizontal axis and turnaround time on the vertical axis, we can see the following dominant proportional relationship.</p> <p></p> <p>To achieve zero soft page faults, heap allocations must only be made from areas that have been first touched in advance.

A callback that takes sensor data message types as input and output should be written in an in-place algorithm as much as possible.

This is a wasteful copying process and should be avoided. We should eliminate unnecessary type conversions by removing dependencies on PCL (e.g., https://github.com/tier4/velodyne_vls/pull/39).

First, calculate the minimum enclosing circle that completely covers the detection area, and then check whether the points are contained in that circle.

For example, when we plot <code>minor-faults</code> on the horizontal axis and turnaround time on the vertical axis, we can see the following dominant proportional relationship.</p> <p></p> <p>To achieve zero soft page faults, heap allocations must only be made from areas that have been first touched in advance. We have developed a library called <code>heaphook</code> to avoid soft page faults while running Autoware callback. If you are interested, refer to the GitHub discussion and the issue.</p> <p>To reduce LLC misses, it is necessary to reduce the working set and to use cache-efficient access patterns.</p> <p>In the sensing component, which handles large message data such as LiDAR point cloud data, minimizing copying is important. A callback that takes sensor data message types as input and output should be written in an in-place algorithm as much as possible. This means that in the following pseudocode, when generating <code>output_msg</code> from <code>input_msg</code>, it is crucial to avoid using buffers as much as possible to reduce the number of memory copies.</p> <pre><code>void callback(const PointCloudMsg &amp;input_msg) {\nauto output_msg = allocate_msg&lt;PointCloudMsg&gt;(output_size);\nfill(input_msg, output_msg);\npublish(std::move(output_msg));\n}\n</code></pre> <p>To improve cache efficiency, implement an in-place style as much as possible, instead of touching memory areas sporadically.

This is a wasteful copying process and should be avoided. We should eliminate unnecessary type conversions by removing dependencies on PCL (e.g., https://github.com/tier4/velodyne_vls/pull/39).

First, calculate the minimum enclosing circle that completely covers the detection area, and then check whether the points are contained in that circle.
