Closed-form and iterative weighted least squares solutions of Helmert transformation parameters
Journal of Geodetic Science, 2013 The Helmert transformation is the most common transformation between different geodetic systems. In 2-D, in contrast to higher dimensions, it is a well-known procedure how to determine the 4 transformation parameters in a closed form.

On the Use of the Helmert Transformation, and its Applications in Panel Data Econometrics [PDF]
Journal of Econometric Methods, 2022 Abstract We revisit the Helmert transformation, and provide a useful and simple derivation of the joint distribution of the sample mean and the sample variance in samples from independently and identically distributed normal random variables.

DEVELOPMENT OF A TIME-DEPENDENT 3-PARAMETER HELMERT DATUM TRANSFORMATION MODEL: A CASE STUDY FOR MALAYSIA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 This paper aims to develop a time-dependent 3-parameter Helmert datum transformation model for Malaysia as a proposed solution to the current non-geocentric issue of the Geocentric Datum of Malaysia 2000 (GDM2000).

Weak Nonlinearity in a Model Which Arises from the Helmert Transformation [PDF]
Applications of Mathematics, 2003 Parameters of a linear conform transformation between two dimensional coordinate systems (Helmert transformation) are estimated from coordinates, so called ``identical points'', measured in both coordinate systems. The regression model characterizing this situation is nonlinear.

Mobile 3D visual search using the Helmert transformation of stereo features [PDF]
2013 IEEE International Conference on Image Processing, 2013 This paper presents a scheme for mobile 3D visual search that facilitates mobile recognition of 3D objects. We use a multi-view approach to extract the 3D geometric information of the query objects and integrate it into SIFT descriptors. To meet a given transmission bandwidth, we use a rate-constrained quad-tree representation for feature selection and

TRANSFORMATION METHODS FOR USING COMBINATION OF REMOTELY SENSED DATA AND CADASTRAL MAPS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 In order to examine using cadastral maps as base maps for aerial orthophotos, two different 2D transformation methods were applied between various coordinate systems. Study area was chosen from Kagithane district in Istanbul.

Remote Sensing, 2018 The noise characteristics of the Global Navigation Satellite System (GNSS) position time series can be biased by many factors, which in turn affect the estimates of parameters in the deterministic model using a least squares method.

Significance of application of the nine parametric coordinate transformation where local state network is not enough reliable [PDF]
Tehnika, 2016 The most commonly used method for establishing the mathematical basis of surveying and spatial data collection is the method of Global Navigation Satellite Positioning System (GNSS).
