Questions tagged [pose-estimation]

The specific task of determining the position and orientation of an object in an image relative to the camera coordinates is called Pose Estimation.

The pose of a camera is also known as the camera Extrinsic Parameters. It is a 3x4 matrix where the first 3 columns are the rotation (orientation) and the las column is the translation (position).

Tensorflow pose estimation strange behaviour

I am trying to detect body parts/landmarks from pictures but I'm facing an issue. For some reason it prints the knee points even when there's no knees in the picture. Any ideas how and why to fix this ? Or what is the better/faster way to detect…

Python library to retrieve face pose from 68 landmark points

Can anyone point me in the direction of a library that can estimate face pose from 68 landmark points in Python? To be more specific, many such libraries exist. However, they usually start from an image. I want to skip the landmark detection because…

Is there a python only version of mediapipe?

I am currently working with a JeVois camera. Code I have previously written for pose estimation with high performance and only using a cpu uses Mediapipe. However, JeVois is not very friendly with added libraries like mediapipe as it is mostly c++…

What's the difference b/w RANSAC-based voting & Hough voting to estimate vector-field for keypoints

The paper "PVNet: Pixel-wise Voting Network for 6DoF Pose Estimation" use RANSAC based voting for localizing keypoints, and further use PnP to calculate object poses. The paper "6DoF Object Pose Estimation via Differentiable Proxy Voting…

Aruco marker : get orientation and position after pose estimation

I want to know the real position and orientation of my marker. If I understood well, tvecs gives me the real position of my marker, I measure the distance with a ruler and it seems be correct even I had sometimes weird values. If someone has an idea…

How a CNN based network developed for 2D RGB data, be trained on 3D data like LINEMOD dataset for object pose estimation?

PoseCNN (PoseCNN: A Convolutional Neural Network for 6D Object Pose Estimation in Cluttered Scenes) is using a CNN as backbone network. CNNs can be trained on 2D RGB data. How can we train the PoseCNN using 3D data (RGB-D like) like LINEMOD,…
