1. A biological information measuring apparatus comprising:
a cover member configured to cover a position of a biological part of a subject, the cover member including a plurality of sensors configured to detect biological signals from the biological part of the subject; and
processing circuitry configured to estimate a positional relation of the position of the biological part of the subject with respect to the cover member at a first time point,
wherein the estimating the positional relation includes, estimating the positional relation of the position of the biological part of the subject with respect to the cover member at the first time point with respect to six degrees of freedom, and
superimposing a first point cloud and a second point cloud,
the first point cloud being acquired by a non-contact mechanism from the subject at the first time point, the first point cloud representing a surface of the biological part of the subject in a coordinate system of the sensors, and
the second point cloud being created based on a morphological image of the subject captured by a biological structure acquiring apparatus, the second point cloud representing the surface of the biological part of the subject.
