LiDAR : A review on generating digital true orthophoto

2011 IEEE 7th International Colloquium on Signal Processing and its Applications, 2011
Light Detection and Ranging (LiDAR) is a technology that has been used for years with the variety of applications including the production of digital terrain models (DTMs), and high-accuracy mapping. LiDAR offers a very detailed collection of 3-D point clouds of the earth surface which can be used in generating orthophotos.

Object-Oriented Automatic Identification of Forest Gaps Using Digital Orthophoto Maps and LiDAR Data

, 2020
Identification of forest gaps is a prerequisite for quantification of their size, shape, and dynamics, and for clarification of both complex structural forest species regeneration and understory species diversity.

Automatic extraction of building statistics from digital orthophotos

International Journal of Geographical Information Science, 2000
In this paper we discuss uses of image segmentation, feature extraction and Bayesian networks for identifying buildings in digital orthophotos and the utilisation of the results for the automated computation of building statistics. Our work differs from previous attempts in a number of ways. Firstly, image segmentation is accomplished using an adaptive

The Gray Processing of Moon Digital Orthophoto Map

Applied Mechanics and Materials, 2012
Considering the mosaic result of the lunar DOM (Digital Orthophoto Map) produced by China's “CE-1” satellite, there usually exists a sharp gray jump beside the joining line. As to a strip image, the gray distribution may be uneven because of the light changing or position difference during photographing.

Satellite true digital orthophoto map generation without elevation data: a New NeRF-based method

Remote Sensing Letters
Existing satellite true digital orthophoto map (TDOM) generation methods are designed for ground elevation data. Obtaining large-scale and high-precision ground 3D data is prohibitively costly, while low-precision elevation data introduces issues such as
