手眼标定

AX=XB，其中，A 是机器人本体的运动变换，B 是相机观测到的目标物运动变换，X 即为待求的手眼矩阵。

坐标系定义

$F_b$: 基座坐标系(Base Frame),固定在机械臂的底座上，是机械臂运动的全局参考坐标系。
$F_e$: 末端执行器坐标系(End-Effector Frame)固定在机械臂末端执行器（例如夹爪或工具）上。
$F_c$: 相机坐标系（Camera Frame）,固定在相机光心的位置，是视觉感知的参考系。
$F_t$: 标定目标坐标系（Calibration Target Frame）：固定在标定目标固定在标定目标（如棋盘格、圆点板）上。

Eye In Hand

眼在手上：相机固定在机械臂末端时，相机与末端执行器之间的变换是固定的。
利用标定板与基座的位置关系保持不变，进行计算：
$$T_t^b=T_{e1}^b{T}_{c1}^{e1}{T}_t^{c1}=T_{e2}^b{T}_{c2}^{e2}{T}_t^{c2}$$
$$T_{e1}^{e2}{T}_c^e=T_c^e{T}_{c1}^{c2}$$
其中$T_c^e$就是最终需要求解的X。

Eye To Hand

眼在手外：相机固定在机械臂以外时，相机与末端执行器的相对位置会随着机械臂的运动而改变。
利用标定板与末端执行器的位置关系保持不变，进行计算：
$$T_t^e=T_b^{e1}{T}_c^b{T}_{t1}^c=T_b^{e2}{T}_c^b{T}_{t2}^c$$
$$(T_{e2}^b{T}_b^{e1})T_c^b=T_c^b(T_{t2}^c{T}_c^{t1})$$
其中$T_c^b$就是最终需要求解的X。

sam和深度估计

Segment Anything Model (SAM)

SAM发展历程

特性	SAM 1 (2023)	SAM 2 (2024)	SAM 3 (2025)
核心能力	静态图像通用分割 (Zero-shot)	视频流实时分割与记忆 (Temporal Memory)	概念理解 + 全量实例分割 (Semantic/Concept)
主要输入	点、框 (Prompts)	点、框 + 记忆库上下文	文本 (Text) + 图像示例 + 点/框
语义理解	无 (只懂几何边界)	弱 (仅靠时序关联)	强 (懂"什么是猫"、“什么是红色的”)
输出逻辑	一次交互 → 一个掩码	一次交互 → 一个时序轨迹	一个概念 → 所有实例的轨迹
典型缺陷	不懂物体是什么；无法处理视频	需要持续交互来修正遮挡	对极其抽象的文本概念可能仍有歧义
最佳场景	PS抠图、辅助标注	视频剪辑、物体追踪	视频搜索、自动驾驶语义分析、机器人指令

单目深度估计

单目深度估计（Monocular Depth Estimation）就是利用人工智能，仅从单张 RGB 图像中，推断出这个丢失的深度信息。单目深度估计通过物体的相对大小，纹理等进行判断相对深度。
