Inspection camera devices and methods with selectively illuminated multisensor imaging
Camera head apparatus, systems, and methods for providing wide angle/panoramic images and/or video of the interior of pipes or other cavities using multiple imaging and illumination modules are disclosed.
1. A camera head for use in a pipe inspection system, comprising: a housing, including: a front housing element including a section having a rounded shape; a transparent sapphire window disposed in the front housing element; and a rear housing element coupled to the front housing element, the rear housing element including a substantially cylindrical longitudinal section; a plurality of imaging modules disposed on or within the front element; a plurality of illumination modules disposed on or within the front element, wherein at least one of the illumination modules of the plurality of illumination modules is disposed between each one of the imaging modules of the plurality of imaging modules: and a push-cable for inserting or retrieving the camera head into a hidden or buried pipe and/or conduit.
2. The camera head of claim 1 , wherein at least two of the plurality of imaging modules have central optical axes that are oriented to align to a common point or centroid within the camera head.
3. The camera head of claim 1 , wherein data corresponding to images or video generated by the imaging modules may be provided to a processing element.
4. The camera head of claim 3 , wherein the images or video from separate imaging modules may be combined or stitched together by the processing element to generate composite wide-angle images covering a wider field of view than that covered by individual imaging modules.
5. The camera head of claim 4 , wherein the composite wide-angle images may be combined to form a wide-angle video file or stream.
6. The camera head of claim 3 , wherein the images or video from separate imaging modules may be transmitted or stored individually for later signal processing or viewing.
7. The camera head of claim 5 , wherein the generated video file or stream may be provided as an output from the processing element to a display element for rendering.
8. The camera head of claim 1 , wherein the push-cable comprises electrical and/or optical cabling for transmission of electrical power to the camera head as well as communication of data and/or images to and/or from the camera head.
9. The camera head of claim 1 , wherein the processing element is incorporated in the camera head.
10. A pipe inspection system, comprising: a camera head comprising: a housing, including: a front housing element including a section having a rounded shape; and a rear housing element coupled to the front housing element, the rear housing element including a substantially cylindrical longitudinal section; a plurality of imaging modules disposed on or within the front element; and a plurality of illumination modules disposed on or within the front element, wherein at least one of the illumination modules of the plurality of illumination modules is disposed between each one of the imaging modules of the plurality of imaging modules; a buried utility locator communicatively coupled to the camera head; and a push-cable for inserting or retrieving the camera head into a hidden or buried pipe and/or conduit.
11. The pipe inspection system of claim 10 , wherein at least two of the plurality of imaging modules have central optical axes that are oriented to align to a common point or centroid within the camera head.
12. The pipe inspection system of claim 10 , wherein data corresponding to images or video generated by the imaging modules may be provided to a processing element.
13. The pipe inspection system of claim 12 , wherein the images or video from separate imaging modules may be combined or stitched together by the processing element to generate composite wide-angle images covering a wider field of view than that covered by individual imaging modules.
14. The pipe inspection system of claim 13 , wherein the composite wide-angle images may be combined to form a wide-angle video file or stream.
15. The pipe inspection system of claim 12 , wherein the images or video from separate imaging modules may be transmitted or stored individually for later signal processing or viewing.
16. The pipe inspection system of claim 14 , wherein the generated video file or stream may be provided as an output from the processing element to a display element for rendering.
17. The pipe inspection system of claim 10 , wherein the push- cable comprises electrical and/or optical cabling for transmission of electrical power to the camera head as well as communication of data and/or images to and/or from the camera head.
18. The pipe inspection system of claim 12 , wherein the processing element is incorporated in the camera head.
