Thermal imaging camera with range detection

摘要

A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes a range imaging camera module that captures the VL and an infrared camera module that captures the IR image. In such examples, the VL image may include a plurality of different portions that each correspond to a different portion of the scene and distance-to-target data associated with each of the different portions of the scene. The camera may align each of the plurality of different portions of the VL image based on the distance-to-target data associated with corresponding portions of the scene so as to correct a parallax error between the VL image and the IR image. The camera may then concurrently display the VL image in alignment with the IR image.

主权项

1. A camera comprising:
a range imaging camera module configured to capture a visible-light (VL) image of a scene along a first optical axis and generate distance-to-target data for the scene, the VL image including a plurality of different portions that each correspond to a different portion of the scene, and the distance-to-target data comprising data representative of distances from the ranging imaging camera module to different objects located at different depths in the scene, the distance-to-target data including a distance-to-target value for each of the different portions of the scene; an infrared camera module configured to capture an infrared (IR) image of the scene along a second optical axis, the second optical axis being offset from the first optical axis so that the IR image of the scene is from a different point of view than the VL image thereby causing a parallax error; a display; and a processor configured to align each of the plurality of different portions of the VL image with the IR image by shifting different portions of the VL image different amounts using the distance-to-target value associated with each portion of the VL image being shifted so as to correct the parallax error between the VL image and the IR image, and control the display to concurrently display at least a portion of the VL image in alignment with at least a portion of the IR image.
