2017-06-01 12:40:39 -0600 | asked a question | Using OpenCV solvePnP for Augmented Reality in OpenGL I'm trying to build an Augmented Reality application in Android using BoofCV (OpenCV alternative for Java) and OpenGL ES 2.0. I have a marker which I can get the image points of using BoofCV's solvePnP function. I want to be able to draw the marker in 3D using OpenGL. Here's what I have so far: On every frame of the camera, I call This is what I have defined as the world points I'm feeding it a square that has origin at its center, with a sidelength in millimeters. I can confirm that the rotation vector and translation vector I'm getting back from I pass the result from solvePnP into my renderer I'm also using the camera intrinsics I get from camera calibration to feed into the projection matrix of OpenGL The square I'm drawing is the one defined in this Google example.

2017-04-24 11:40:46 -0600 | asked a question | OpenCV tracker: The model is not initialized in function init On the first frame of a a video, I'm running an object detector that returns the bounding box of an object like this: I want to pass this bounding box as the initial bounding box to the tracker. However, I get the following error: The frame shape is I'm not sure if the order I'm sending the bounding box is wrong, or if I'm doing something else wrong. It doesn't error out when I do something like X-posting from this SO question, as this is kind of time sensitive - would appreciate any help! |
