Systems and methods for determining regions suitable for gas imaging processes
First Claim
1. A portable, hand-held camera system comprising:
- a camera module including a sensor configured to receive radiation from a target scene and generate image data representative of the target scene, the sensor being sensitive to at least a first wavelength of light; and
a processor;
wherein the system is configured to;
capture an image of a target scene, the image comprising a plurality of regions, each region comprising a set of one or more pixels;
analyze a plurality of regions in the image;
determine which of the analyzed plurality of regions in the image are unsuitable for performing a gas imaging process of a target gas; and
alert a user of the presence of one or more regions that are unsuitable for performing a gas imaging process of a target gas.

Abstract
Aspects of the invention generally relate to illumination gas imaging and detection. Camera systems can illuminate a target scene with light sources configured to emit absorbing and non-absorbing wavelengths with respect to a target gas. An image of the target scene illuminated with a non-absorbing wavelength can be compared to a non-illuminated image of the target scene in order to determine information about the background of the target scene. If sufficient light of the non-absorbing wavelength is scattered by the scene toward a detector, the target scene comprises an adequate background for performing a gas imaging process. A camera system can alert a user of portions of the target scene suitable or unsuitable for performing a gas imaging process. If necessary, the user can reposition the system until sufficient portions of the target scene are recognized as suitable for performing the gas imaging process.

12. A non-transitory computer-readable medium comprising executable instructions for causing one or more programmable processors to:
-
receive a first set of image data representative of a target scene at a first point in time; receive a second set of image data representative of the target scene at a second point in time, the second point in time being different from the first; compare one or more regions in the first set of image data to corresponding regions in the second set of image data; for each of the one or more regions, based on the comparison; determine whether or not the region is suitable for detecting a gas in the target scene; if the region is suitable for detecting a gas in the target scene, consider such region to be an operable gas detection region; and if the region is not suitable for detecting a gas in the target scene, consider such region to be an inoperable gas detection region; generate gas detection image data representative of the target scene, wherein regions in the gas detection image data corresponding to operable gas detection regions are visually distinguishable from regions in the gas detection image data corresponding to inoperable gas detection regions. - View Dependent Claims (13, 14)

15. A portable, hand-held camera system comprising:
-
a first light source capable of emitting light at a first wavelength, the first wavelength not being an absorption wavelength of a target gas; a second light source capable of emitting light at a second wavelength, the second wavelength being an absorption wavelength of the target gas; a camera module comprising a lens assembly having an associated sensor for detecting images of a target scene, the sensor being sensitive to a range of wavelengths of light including the first wavelength and the second wavelength; and a processor in communication with the camera module and configured to; capture image data of a target scene, the image data comprising a plurality of regions, each region comprising a set of one or more pixels; analyze a plurality of regions in the captured image data; determine which of the analyzed plurality of regions in the image data are suitable for performing a gas imaging process of the target gas; and determine which of the analyzed plurality of regions that are suitable for performing the gas imaging process are representative of gas in the target scene. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
