AI-supported Framework of Semi-Automatic Monoplotting for Monocular Oblique Visual Data Analysis

arXiv.org Artificial Intelligence

In the last decades, the development of smartphones, drones, aerial patrols, and digital cameras enabled high-quality photographs available to large populations and, thus, provides an opportunity to collect massive data of the nature and society with global coverage. However, the data collected with new photography tools is usually oblique - they are difficult to be georeferenced, and huge amounts of data is often obsolete. Georeferencing oblique imagery data may be solved by a technique called monoplotting, which only requires a single image and Digital Elevation Model (DEM). In traditional monoplotting, a human user has to manually choose a series of ground control point (GCP) pairs in the image and DEM and then determine the extrinsic and intrinsic parameters of the camera to establish a pixel-level correspondence between photos and the DEM to enable the mapping and georeferencing of objects in photos. This traditional method is difficult to scale due to several challenges including the labor-intensive inputs, the need of rich experience to identify well-defined GCPs, and limitations in camera pose estimation. Therefore, existing monoplotting methods are rarely used in analyzing large-scale databases or near-real-time warning systems. In this paper, we propose and demonstrate a novel semi-automatic monoplotting framework that provides pixel-level correspondence between photos and DEMs requiring minimal human interventions. A pipeline of analyses was developed including key point detection in images and DEM rasters, retrieving georeferenced 3D DEM GCPs, regularized gradient-based optimization, pose estimation, ray tracing, and the correspondence identification between image pixels and real world coordinates. Two numerical experiments show that the framework is superior in georeferencing visual data in 3-D coordinates, paving a way toward fully automatic monoplotting methodology.


Artificial Intelligence Projects with Python

#artificialintelligence

In this course, we aim to specialize in artificial intelligence by working on 14 Machine Learning Projects and Deep Learning Projects at various levels (easy - medium - hard). Before starting the course, you should have basic Python knowledge. Our aim in this course is to turn real-life problems that seem difficult to do into projects and then solve them using latest versions of artificial intelligence algorithms (machine learning algortihms and deep learning algorithms) and Python(3.8). This course was prepared in August 2021. We will carry out some of our projects using machine learning and some using deep learning algorithms.


The incoming AI revolution in media

#artificialintelligence

Whether it plays go, drives cars or learns to speak, artificial intelligence (AI) is now everywhere, benefitting a wide range of industries. Like many others, the media industry has already been radically changed by the rise of the internet and new technology. It is thus all the more logical to reflect on what's coming next, and there's no doubt that artificial intelligence will play a significant role. I was at MaddyKeynote 2021 to discuss this topic with two professionals of the industry, Guillaume Doret, CEO of Synchronized, and Arnaud Maupin, director of innovation at Group TF1. According to Guillaume Doret, AI provides cable news channels with a tremendous opportunity to index and monetize their video archives.


Will Nathan Drake Make This Jump in the Uncharted Trailer?

WIRED

You've played the video game, but now there's a movie coming out based on Uncharted. One part of the trailer really got me interested--from a physics perspective. It shows a cargo plane with a long string of large boxes roped together and hanging out the back. He climbs the string of boxes one by one until he reaches one closest to the plane, then he jumps, making a leap towards the interior. I have no idea why Drake is doing this, but it opens up a great physics question: Does he make it?
