  • Publication number: 20220166907
    Abstract: Various techniques are provided for implementing an imaging system with multiple infrared imaging modules provided in proximity to a visible light imaging module with overlapping fields of view. In one example, a system includes an array of infrared imaging modules configured to capture infrared images overlapping in a shared field of view of the array. The system also includes a visible light imaging module configured to capture a visible light image with a field of view overlapping with the shared field of view of the array. The system also includes a logic device configured to process the infrared images to provide an increased resolution infrared image corresponding to the shared field of view of the array, and generate a combined image comprising content from the increased resolution infrared image and content from the visible light image. Additional methods and systems are also provided.

  • Patent number: 10728517
    Abstract: A method for facilitating parallax mitigation includes capturing a first image of a scene using a first imaging device, where the first imaging device is associated with a first optical axis. The method further includes tilting a second optical axis associated with a second imaging device to obtain a tilted optical axis. The method further includes capturing a second image of the scene using the second imaging device and the tilted optical axis.
