Abstract
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.
Claims29
A camera head, comprising:
- a housing, including:
- a front housing element including a section having a rounded, half-spherical shaped section;
- 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 about the rounded section so as to capture images from circularly offset angles relative to each other;
- and
- a plurality of illumination modules disposed on or within the front element between ones of the imaging modules so as the plurality of imaging modules including a first set of one or more imaging modules and a second set of one or more imaging modules;
- wherein the illumination modules are selectively controlled in conjunction with an imaging operation of one or more of the imaging modules, where the operation includes adjusting the level of the light output from the first set of illumination modules so that the light output level from the first set of illumination modules is higher during a first imaging time interval than during non-imaging time intervals and the level of the light output from the second set of illumination modules is maintained at a low output level during the first time interval, and adjusting the light output of the second set of illumination modules so that the light output of the second set of illumination modules is higher during a second imaging time interval, different from the first imaging time interval while the level of the light output from the first set of illumination modules is maintained at a low output level during the second time interval;
- and
- wherein a plurality of images captured by one or more of the imaging modules at different light output levels are combined to generate a high dynamic range (HDR) image or video.
