“…A homologous window of the same size is searched on the other image that will maximize a correlation function. The process can be refined to obtain a precision that reaches one-tenth of a pixel in the ideal case [17,18] which is 0.25 m for a SPOT-5 image with a 2.5 m resolution. Various correlation functions can be used that can be statistical or defined in the frequency domain after the decomposition of the image signal in its frequency components.…”

“…Less noisy results can be obtained with larger windows but with less precision. Rosu et al [18] have tested the effect of window size on the precision of the results. Only the south-north component of the displacement measured by DGPS is available.…”

“…On two images acquired at different times and ortho-rectified (geometrically corrected from the topographic effect), homologous points are detected by correlation methods with a theoretical sensitivity of one-tenth of a pixel [17,18].The shift detected between the homologous points on the two images corresponds to the displacement that occurred between the acquisition of the two images. The correlation of ortho-rectified optical images has been applied to measure the co-seismic displacement fields [19,20], the displacement of glaciers [21,22], of landslides [23], and of dunes [24].…”

“…Thus, there is a democratization of data and techniques which were reserved until recently to specialists of image processing. Potential limitations of these correlation techniques applied to remote sensing data have been partially explored [18]. For an optimal result, it is better to work on bare soils with a series of images acquired with similar incidence angles to avoid the differences in geometries that can be produced by the ortho-rectification process using a DEM at low resolution.…”

Over the last 10 years, the accessibility of high spatial resolution remote sensing images has strongly increased. These images are available in ortho-rectified format which do not necessitate any further geometrical processing to be analyzed. In parallel, image correlation software has become more efficient and friendly. In this paper, image correlation methods are tested to evaluate their potential and limitations to measure the surface displacements in a complex case of a landslide located in a tropical environment. This studied landslide, called "Mare à Poule d'Eau", is located in the Salazie erosion watershed in Réunion Island (France). This landslide is monitored daily by a DGPS station which registers the south-north displacements. Two pairs of ortho-rectified SPOT-5 images at 2. The displacement can be estimated by applying a correction factor extracted from the ICP located in the stable areas. The potential and limits of the image correlation in such complex environments is discussed. A strategy is proposed to evaluate the quality of the results and to extract the displacement signal from the shift measurements.

ABSTRACT:This publication presents the RPC-based bundle adjustment implemented in the freeware open-source photogrammetric tool Apero/MicMac. The bundle adjustment model is based on some polynomial correction functions, enriched with a physical constraint that introduces the notion of a global sensor rotation into the model. The devised algorithms are evaluated against two datasets consisting of two stereo and a triplet pair of the Pleiades images. Two sets of correction functions and a number of GCPs configurations are examined. The obtained geo-referencing accuracy falls below the size of 1GSD.

Application of open‐source photogrammetric software MicMac for monitoring surface deformation in laboratory models

et al. 2016

Quantifying deformation is essential in modern laboratory models of geological systems. This paper presents a new laboratory monitoring method through the implementation of the open‐source software MicMac, which efficiently implements photogrammetry in Structure‐from‐Motion algorithms. Critical evaluation is provided using results from two example laboratory geodesy scenarios: magma emplacement and strike‐slip faulting. MicMac automatically processes images from synchronized cameras to compute time series of digital elevation models (DEMs) and orthorectified images of model surfaces. MicMac also implements digital image correlation to produce high‐resolution displacements maps. The resolution of DEMs and displacement maps corresponds to the pixel size of the processed images. Using 24 MP cameras, the precision of DEMs and displacements is ~0.05 mm on a 40 × 40 cm surface. Processing displacement maps with Matlab® scripts allows automatic fracture mapping on the monitored surfaces. MicMac also offers the possibility to integrate 3‐D models of excavated structures with the corresponding surface deformation data. The high resolution and high precision of MicMac results and the ability to generate virtual 3‐D models of complex structures make it a very promising tool for quantitative monitoring in laboratory models of geological systems.
