Camera Self-Calibration by an Equilateral Triangle
نویسندگان
چکیده
In this article, we present a technique for self-calibration of a CCD camera with constant focal distance using a planar scene. The particularity of our technique is the use of triangle equilateral which two vertices are defined from the matches detected in images taken by the camera. Using these vertices to estimate all the projection matrices which are operated with homographies between the images to estimate the intrinsic parameters of the camera. Experimental results show the robustness of our algorithms in terms of stability and

Clean formation and dynamic exchange reactions of a supramolecular equilateral triangle that is both heterometallic and heteroleptic.
The self-assembly of an equilateral triangle that is both heterobimetallic and heteroleptic, its metal exchange to a homometallic triangle and further ligand exchange (= edge of the triangle) were elaborated.
متن کاملCamera Calibration Based on the Common Self-polar Triangle of Sphere Images
Sphere has been used for camera calibration in recent years. In this paper, a new linear calibration method is proposed by using the common self-polar triangle of sphere images. It is shown that any two of sphere images have a common self-polar triangle. Accordingly, a simple method for locating the vertices of such triangles is presented. An algorithm for recovering the vanishing line of the s...
متن کاملOn the Optimality of Napoleon Triangles
An elementary geometric construction, known as Napoleon’s theorem, produces an equilateral triangle, obtained from equilateral triangles erected on the sides of any initial triangle: The centers of the three equilateral triangles erected on the sides of the arbitrarily given original triangle, all outward or all inward, are the vertices of the new equilateral triangle. In this note, we observe ...
متن کاملA note on perfect dissections of an equilateral triangle
A perfect dissection of a polygon P into a polygon P ′ is a decomposition of P into internally disjoint pairwise incongruent polygons all similar to P ′. It is known that there is no perfect dissection of an equilateral triangle into smaller equilateral triangles. On the other hand, an equilateral triangle has trivial perfect dissections into any number n of right triangles where n ≥ 3. We give...
متن کاملAn Interactive Control Algorithm Used for Equilateral Triangle Formation with Robotic Sensors
This paper describes an interactive control algorithm, called Triangle Formation Algorithm (TFA), used for three neighboring robotic sensors which are distributed randomly to self-organize into and equilateral triangle (E) formation. The algorithm is proposed based on the triangular geometry and considering the actual sensors used in robotics. In particular, the stability of the TFA, which can ...
