Merging Depth Maps for multi view stereo?

Is there a simple to implement way of merging depth maps? I take pictures of a statue from 3 different positions .Then each stereo pair produces a disparity map.I re-project it to depth using triangulation .Finally I get 3 set of 3d points.How can I…

Absolute depth from iPhone X back camera using disparity from AVDepthData?

I'm trying to estimate the absolute depth (in meters) from an AVDepthData object based on this equation: depth = baseline x focal_length / (disparity + d_offset). I have all the parameters from cameraCalibrationData, but does this still apply to an…

Problem with stereo rectification using OpenCV and Python

I am working on a stereo camera rig with 4 discrete cameras (of the same type) but at the moment only one pair (cam1 and cam2) are necessary. The aim is to calibrate the stereo pair and get 3D information about the scene. I am using Python 3.6 with…

Rotation and Translation from Essential Matrix incorrect

I currently have a stereo camera setup. I have calibrated both cameras and have the intrinsic matrix for both cameras K1 and K2. K1 = [2297.311, 0, 319.498; 0, 2297.313, 239.499; 0, 0, 1]; K2 =…

Stereo Disparity map generation

I am working on KITTI data set i am taking 2 images and finding the disparity to get 3D point cloud .The problem which i am facing is that i am not able to get a good disparity map.Most of the disparity value is less than 0.1 .The disparity values…

Pose from Fundamental matrix and vice versa

I have computed the Fundamental Matrix between two cameras using opencv's findFundamentalMat. Then I plot the epipolar lines in the image. And I get something like: Now, I tried to get the pose from that fundamental matrix, computing first the…

OpenCV Stereo rectification from manually created matrices

I am currently working on a 3d reconstruction of X-Ray images, and therefore I need to stereo-rectify images of two views before I can match some features with help of the epilines. I am using OpenCV 2.4 with C++. For this purpose I got a set of…

In a calibrated stereo-vision rig, how does one obtain the "camera matrices" needed for implementing a 3D triangulation algorithm?

I am trying to implement the (relatively simple) linear homogeneous (DLT) 3D triangulation method from Hartley & Zisserman's "Multiple View Geometry" (sec 12.2), with the aim of implementing their full, "optimal algorithm" in the future. Right now,…
