示例1: trilateration_phase
# 需要导入模块: from circle import Circle [as 别名]
# 或者: from circle.Circle import intersection_with [as 别名]
def trilateration_phase(points_in, distance_matrix):
points_out = [points_in[0]] # force point 0 to stay at origin
for target_idx in range(1, len(points_in)):
approximations = [] # points which are approximate 'target'
# we want pairs of circles which intersect at target. Will have circle A and circle B.
for source_a_idx, source_b_idx in itertools.combinations(range(0, len(points_in)), 2):
# ensure the centre of the circle isn't target.
# It must be defined by another point and target
if (source_a_idx != target_idx) and (source_b_idx != target_idx):
a_center = points_in[source_a_idx]
a_rad = distance_matrix[source_a_idx][target_idx]
a = Circle(a_center, a_rad)
b_center = points_in[source_b_idx]
b_rad = distance_matrix[source_b_idx][target_idx]
b = Circle(b_center, b_rad)
intersections = a.intersection_with(b)
approximations.append(points_in[target_idx].get_closest(intersections))
approximation = get_centroid(approximations)
points_out.append(approximation)
