a support adapted to support the sensorized device in the hostile environment; a processor of the image data generating a spherical and/or three-dimensional image based on the image data; and a remote display device with respect to the sensorized device adapted to be positioned outside the hostile environment and in communication with at least the processor of the image data, the apparatus being adapted for a hostile environment with temperatures and/or atmospheric contaminants harmful or dangerous for human beings, and the plurality of sensors detecting contemporaneous image data of at least 60% of 4π steradians of the hostile environment. ## Claims ### Claim 1 An apparatus for inspection of a hostile or harsh environment comprising: a sensorized device (26) comprising a plurality of image sensors (42,44,46,48) positioned with different orientations with respect to each other, so as to detect image data or a plurality of images in a sequence forming a video of said hostile or harsh environment; a support (30) adapted to support said sensorized device in said hostile or harsh environment; a processor of said image data adapted to generate one or both of a spherical or three-dimensional image either static or as a sequence forming the video based on said image data; and a remote display device with respect to said sensorized device (26), adapted to be positioned outside the hostile or harsh environment and in communication with at least the processor of the image data, wherein said apparatus is adapted for said hostile or harsh environment, said hostile or harsh environment being in a high temperature furnace and having one or both of temperature characteristics or atmospheric contaminants harmful or dangerous for human beings, wherein said plurality of sensors having different orientations with respect to each other are sensors that detect contemporaneous image data of at least 60% of 4π steradians of said hostile or harsh environment, wherein said plurality of image sensors (42, 44, 46, 48) are housed inside a single protective shell (52), wherein said protective shell is polyhedral, and wherein said plurality of image sensors are disposed inside said protective shell to each view through a different one of at least five faces of said protective shell; further comprising a stable positioning system, adapted to position the sensorized device (26) consistently in a same, predetermined position within said hostile or harsh environment during subsequent inspections. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein said protective shell comprises a metal frame with transparent crystals applied to said frame, and is operatively connected to a cooling unit adapted to cool said shell with a cooling fluid. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein said image sensors (42,44,46,48) that detect the image data or the plurality of the images in the sequence forming the video are selected from the group consisting of sensors that are: sensitive to a visible portion of a light spectrum, sensitive to an infrared portion of the light spectrum, sensitive to an ultraviolet portion of the light spectrum; thermographic, or heat sensitive, or sensitive to X rays. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein said image sensors (42,44,46,48) are positioned so as to detect the contemporaneous image data of at least 90% of 4π steradians of said hostile or harsh environment. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein said image data comprise one or both of a video film or static images. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein there are five sensors disposed perpendicularly from one another. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein at least some of said plurality of sensors are disposed on a same plane spaced at less than 90° from one another. ### Claim 8 A method of inspecting a hostile or harsh environment in a high temperature furnace, comprising the following steps: a. detecting, with image sensors (42,44,46,48), image data of said hostile or harsh environment without use of any moving parts during image data acquisition; b. transmitting said image data outside of said hostile or harsh environment; and c. re-processing said image data in order to reconstruct an image, wherein said method is implemented for inspection of the hostile or harsh environment which has one or both of temperature characteristics or atmospheric contaminants that are harmful or dangerous for human beings, wherein the step of detecting is performed with the image sensors (42,44,46,48) that detect contemporaneous image data of at least 60% of 4π steradians of said hostile or harsh environment, thereby creating one or both of a spherical or three-dimensional image or a plurality of images in sequence forming a video based on said image data, said image sensors (42,44,46,48) being housed in a protective shell (52), and wherein said step a. comprises introducing a single sensorized shell (26) containing the image sensors (42,44,46,48) that acquires the image data in a predetermined position in said hostile or harsh environment, so as to detect the image data or a plurality of images in sequence forming a video comparable with other sets of image data acquired at a different time, to recognize pattern differences that are indicative of a dangerous situation taking place, said protective shell being polyhedral, and said plurality of image sensors being disposed inside said protective shell to each view through a different one of at least five faces of said protective shell. ### Claim 9 (depends on 8) The method according to claim 8, wherein said step a comprises detecting the image data of at least 90% of 4π steradians of said hostile or harsh environment. ### Claim 10 (depends on 8) The method according to claim 8, wherein said step a comprises detecting the image data using sensors sensitive to at least one of the following: a visible portion of a light spectrum, an infrared portion of the light spectrum, an ultraviolet portion of the light spectrum, thermographic, or heat sensitive, or sensitive to X rays. ### Claim 11 (depends on 8) The method according to claim 8, wherein said image data comprise one or both of video films or static images. ### Claim 12 (depends on 8) The method according to claim 8, further comprising the step of comparing the image data relating to a same area of the hostile or harsh environment taken at different moments.
