        <description>畸变

一、畸变的定义与类型

畸变（distortion）是一种十分独特的几何像差。它并不影响成像的清晰程度，却会使实际场景中原本平直的线条发生弯曲，从而改变物像之间的几何相似性。



畸变是主光线的行为，不同视场的实际横向放大率不同，畸变现象也不同。$$D = \frac{\Delta H}{H} \cdot 100$$$\Delta H$$H$$(x_{real}, y_{real})$$r_{\text{real}} = r_{\text{ideal}} \left(1 + k_1 r^2 + k_2 r^4\right)$$$          A      =          \frac{A_{1}+A_{2}}{2}      $$$$ SMIA= \frac{A-B}{B} \times100% $$$A_{1}$$A_{2}$…</description>

        <description>畸变

一、什么是畸变？

畸变（Distortion）是指光学系统对物体所成的像相对于物体本身产生的几何失真。它由透镜边缘与中心区域的横向放大倍率不一致引起。畸变仅改变物体的空间几何形状，而不影响图像的清晰度（分辨率）。</description>

概念

在车载摄像头监控系统（CMS）中，畸变指成像结果与理想投影模型的偏差，其定义随理想基准不同而变化。

为适配工程应用，主要分为两类：


	*  TV 畸变：以单一参考值表征画面整体弯曲程度，是快速评估系统畸变水平的实用指标。$h_{ideal}$$\text{RadialDistortion} = \frac{\Delta h}{h_{ideal}} = \frac{h_{monitor} - h_{ideal}}{h_{ideal}} = \frac{h_{monitor}}{h_{ideal}} - 1$$h_{monitor}$$h_{ideal}$$h_{monitor}$$h_{monitor}(i) = \frac{1}{2}\left[ w_{monitor}(i) - w_{monitor}(i_{centre}) \right]$$w_{monitor}(i)$$i$$i_{centre}$$h_{ideal}$$h_{monitor}$$h_{ideal}$…</description>

        <description>成像质量评价

 概述

成像质量评价（Image Quality Assessment, IQA）指在给定条件（如相机的被摄场景、照明环境及显示设备的输入等）下，对成像系统的成像性能（如分辨率、噪声、畸变、色彩、动态范围等）进行主客观分析与评估。成像质量直接影响图像的实用价值 —— 例如人类观察者的视觉体验（如欣赏照片或影片）或目视效果（如使用</description>

        <description>色差

一、什么是色差


色差，也称为“色边”或“紫边”，是一种常见的光学问题，当透镜不能将所有波长的颜色聚焦到同一焦平面时，或当颜色的波长聚焦在焦平面的不同位置时，就会出现这种问题。色差是一种常见的镜头像差现象，常在图像最暗或最亮的边界区域显现出彩色条纹或紫色条纹。它是如何产生的呢？</description>

        <description>入瞳及其在相机成像测试中的应用

当我们观察人眼时，可见一黑色小孔（即瞳孔），所有入射光均通过瞳孔进入人眼。从生理上说，瞳孔是虹膜中央的孔，但我们观察到的并不是瞳孔本身，而是瞳孔通过其前面的屈光结构（如角膜、前房等）所成的像。相似地，如果我们在一个明亮的环境，从正面观察一个照相机镜头，会看到一个明亮的斑，这个斑便是镜头的光圈（通常置于镜片之间）经过其前面的镜片所成的像，称为入射光瞳（以下简称入瞳）。在相机的成像测试中，入瞳是一个十分重要的概念，有着广泛的应用。在本文中，我们就与大家一同来认识入瞳。…</description>

        <description>点云 (Point Cloud)

一、定义：

点云是激光雷达输出的对三维空间获取的点的集合。它通过记录激光脉冲在物体表面的反射，将物理世界的几何形状转化为海量离散的空间坐标点，是自动驾驶环境感知、定位与高精地图构建等的核心底层数据。</description>
