Fig. 1. Localization setup in 2D. The measured distance dmn and thedirected angle αmn can be be mutually expressed with the vectorvmn or, equivalently, with the signed projections on the x- and y-axis: xmn and ymn. Triangle ∆ℓ is such that vi − vh = vk.

We define the edge vector vmn corresponding to the pair of points(xn,xm) by

vmn = xm − xn. (1)

The length of the edge vector is the distance between the points,denoted by

dmn = ∥xn − xm∥2, (2)

while dmn refers to its noisy measurement. The orientation of thevector is defined with a directed angle, meaning that it lies between0 and 2π with respect to some common reference direction (in thiscase the x-axis). This assumption is realistic because devices areoften equipped with a compass, providing their absolute orientation.Therefore, we can use any off-the-shelf method [17] to measure thedirections of arrival and then convert them into directed angles. Wedenote the noiseless and noisy measured directed angles by αmn

and αmn, respectively, as depicted in Fig. 1. Then, the coordinatesof edge vectors relate to distances and angles as

(vmn)x = dmn cosαmn and (vmn)y = dmn sinαmn. (3)

Our goal is to estimate the points X , given noisy measurementsof distances dmn and angles αmn.

3. EDGE-KERNEL BASED SOLUTIONS

Before describing our constrained edge-kernel approach, we firstsummarize the original edge-kernel method [16].

3.1. The Edge-Kernel Formulation

In [16], Macagnano et al. propose a new MDS formulation, referredto as edge multidimensional scaling (E-MDS), which allows a uni-fied processing of angle and range information. In the E-MDS-basedformulation, the entities are the vectors pointing from one point toanother, while the measure of dissimilarity is their inner product.

To simplify the notation and allow the construction of a matrixwhose elements depend on two edge vectors i and j, we first re-index

the edges vmn from (1) to vi with i = (m− 1)N − m(m+1)2 + n,

where m = 1, . . . , N − 1, n = m + 1, . . . , N , and i = 1, . . . , E,E = N(N−1)

2 . If we consider a matrix consisting of elements vmn,this corresponds to flattening the elements of its upper triangle in arow-wise order. Then, we define the edge-kernel KE ∈ RE×E of afully connected point set with E edges and the element (i, j) as

(KE)ij = ⟨vi,vj⟩ = ⟨xm − xn,xq − xp⟩= dmndpq cos (φij),

(4)

where dmn is defined in (2), and φij is the inner angle between vec-tors vi and vj . In matrix form, (4) simplifies to

KE = V V ⊤ = dEd⊤E Ω, (5)

where V ∈ RE×2 is the matrix of the edges, dE ∈ RE is the vectorof the edge lengths and represents the Hadamard (entrywise) prod-uct. The elements Ωij of the angle matrix Ω contain the cosines ofthe inner angles between vi and vj . From (5), it is easy to verifythat the rank of the edge kernel is at most 2. Given noisy angle anddistance measurements, the authors in [16] propose to reconstruct adenoised kernel by imposing this low-rank constraint and positive-semidefiniteness:

V = argminV ∈RE×2

∥KE − V V ⊤∥F

= diag!dE

"· [U Ω]1:E,1:2 · [ΛΩ]

121:2,1:2 ,

(6)

where KE = dEd⊤E Ω is the measured edge kernel and U Ω and

ΛΩ are the matrices of eigenvectors and eigenvalues of Ω, respec-tively. Recovering the point set X from V is straightforward oncewe set the translation of X by fixing one point. It consists of solvinga sparse linear system of equations defined in [16].

3.2. Constrained Edge-Kernel

The above solution outperforms previous approaches, which includedistance-only techniques [18] as well as methods combining bothdistances and angles [18, 19]. However, it neglects certain geometricconstraints, which means the recovered vectors are not guaranteedto be geometrically consistent. Indeed, imposing the kernel struc-ture ignores triangle equalities of the edge vectors. Therefore, wepropose a new method, which we call constrained edge-kernel, toaddress this limitation.

To better exploit geometric information for denoising, we intro-duce the novel notion of a triangle constraints matrix M ∈ RC×E .This matrix incorporates the mutual dependencies of edge vectorsforming a triangle, with Mℓi = 1, Mℓk = Mℓj = −1, assumingthat the vectors vi, vj and vk form the triangle ∆ℓ (see Fig. 1).The number of constraints C equals to the number of triangles in thepoint set, C =

#N3

$. The problem given in (6) can then be written as

the rank-constrained optimization,

KE =argminK

∥KE −K∥F

subject to K ∈ C and K ∈ R,(7)

where we introduce the feasibility sets

R =%X ∈ RE×E : X ≽ 0, rank (X) = 2

&, (8)

C =%X ∈ RE×E : MX = 0

• We proposed two algorithms for multimodal sensor localization:• Constrained Edge-Kernel improves on the existing Edge-Kernel

method by adding geometric constraints on triplets of points.• Coordinate Difference Matrices allow us to estimate the sensors’

coordinates independently for each dimension.• Numerical simulations demonstrate that both proposed methods significantly

outperform existing distance-based and multimodal localization algorithms.

State-of-the-art• Distance-only: MDS [1]

• Distance + angles: E-MDS [3]

Experiment• 6 points chosen uniformly in the unit square

• Compute RMSE on reconstructed points

RMSE vs. angular noise• RMSE vs. angular noise for two representative distance noise levels

RMSE vs. distance noise• RMSE vs. distance noise for two representative angle noise levels

Compute W 0, S0

and 0by removing the first row and column W , S and .
