Abstract:
A hybrid phantom having marker patches that are visible both in a thermal image captured by a thermal camera and a 3D point cloud generated by a 3D camera. A thermal insulation between the marker, patches and a carrier part of the phantom maintains a temperature difference between the marker patches and the carrier part such that the marker patches are visible in the thermal image. Different optical properties of the marker patches and the carrier part make them distinguishable in the 3D point cloud.
