This document summarizes a paper titled "DeepI2P: Image-to-Point Cloud Registration via Deep Classification". The paper proposes a method for estimating the camera pose within a point cloud map using a deep learning model. The model first classifies whether points in the point cloud fall within the camera's frustum or image grid. It then performs pose optimization to estimate the camera pose by minimizing the projection error of inlier points onto the image. The method achieves more accurate camera pose estimation compared to existing techniques based on feature matching or depth estimation. It provides a new approach for camera localization using point cloud maps without requiring cross-modal feature learning.
Onomichi Hirokazu gave an introduction to connecting ROS and VRChat. He discussed using VRChat as a virtual environment to interact with robots in simulation. Key points included using ROS and OSC messages to control virtual objects from a real robot, and using a virtual motion tracker and ROS tf to map robot joint states to an avatar in VRChat. He demonstrated controlling an avatar's limbs based on data from Dynamixel servos. The goal is to enable remote participation in robot events using VR.

16. YOLO V1 的核心精神
“We frame object detection as a regression
problem to spatially separated bounding
boxes and associated class probabilities.”
18. 每個grid cell 預測
1. B 個框框的位置 (x, y, w, h)
2. 框框有沒有物件(confidence)劃分成 S×S 個grid cell
框框中心落在某grid cell内部
則中心 cell 負責 classification
每個框框預測 C
個條件機率
最後輸出 S x S x (5*B + C) 的 tensor
eg.
S = 7, B = 2, C = 20 (20 classes)
=> 是7×7×30 的 tensor
