Abstract
Mono-plotting from a single photo is an efficient method to 3D spatial information collection. The core of the monoplotting process is an algorithm to determine the ground coordinates of pixel points in a single image by intersecting the view ray with the DEM-defined surface. A traditional algorithm used in photogrammetry is to iteratively calculate the coordinates based on the inverse collinearity equations. Being an iterative method, this algorithm may induce errors to the derived coordinates. When the iteration precision (the distance between the last two iterated points) becomes less than a predefined precision threshold, the iteration is considered convergent and the ground coordinates are produced. However, the true error of the output coordinates may be still worse than the threshold. This paper theoretically investigates the error budget of the iterative algorithm, models the true error from the iteration precision, and estimates the algorithm-induced error in the ground coordinate output.
