SYSTEMS AND METHODS FOR DYNAMIC REGISTRATION OF MULTIMODAL IMAGES

摘要

Various techniques are disclosed for a system and method to dynamically co-register images captured by two or more separate imaging modules. For example, in one embodiment, a method includes: capturing a thermal image of an object; capturing a visible light (VL) image of the object; determining a plurality of thermal image reference points from the thermal image; determining a plurality of VL image reference points from the VL image; determining a geometric transform based on the plurality of thermal image reference points and the plurality of VL image reference points; and applying the geometric transform to the thermal image or the VL image to align the thermal image and the VL image. In another embodiment, an imaging system comprises two or more separate imaging modules and one or more processors configured to perform the method above to dynamically co-register images.

1. An imaging system, comprising:
a thermal imaging device comprising a thermal imaging module configured to capture a thermal image of an object; a visible light (VL) imaging device comprising a VL imaging module configured to capture a VL image of the object; and one or more processors communicatively coupled to the thermal imaging module and the VL imaging module, the one or more processors configured to:
determine a plurality of thermal image reference points from the thermal image,determine a plurality of VL image reference points from the VL image,determine a geometric transform based on the plurality of thermal image reference points and the plurality of VL image reference points, such that the geometric transform at least approximately maps the plurality of thermal image reference points to the plurality of VL image reference points or at least approximately maps the plurality of VL image reference points to the plurality of thermal image reference points, andapply the geometric transform to the thermal image or the VL image to align the thermal image and the VL image.
