Web7 de jul. de 2015 · I have a set of 2D image keypoints that are outputted from the OpenCV FAST corner detection function. Using an Asus Xtion I also have a time-synchronised depth map with all camera calibration parameters known. Using this information I would like to extract a set of 3D coordinates (point cloud) in OpenCV. In one of our previous posts, we created a custom low-cost stereo camera setup and calibrated it to capture anaglyph 3D videos. In this post, we used the calibrated stereo camera setup for depth estimation. Based on this experience, it is clear that building a custom stereo camera is a time consuming and involved … Ver mais In the first post of the Introduction to spatial AI series,we discussed two essential requirements to estimate depth (the 3D structure) of a given scene: point correspondence and … Ver mais Given we have a horizontal stereo camera setup, the corresponding points for a rectified stereo image pair would have the same Y coordinate. So how do we go about finding the … Ver mais The basic concept of obstacle avoidance is determining if the distance of any object from the sensor is closer than the minimum threshold distance. In our case, the sensor is a stereo camera. Another type of device widely … Ver mais Till now, the grayscale images we have been obtaining are just the disparity maps and not the depth maps.
