1. An endoscopic or borescopic vision system for inspecting an inside of a cavity or guiding operation on enclosed structures in said cavity, comprising:

  • an imaging system to receive selected images of a target object and to create output signals of the target object image;

    the imaging system comprising a camera system arranged to create output signals of different object images of portions of the target object structure or a direct environment thereof, the camera system comprising a first ocular system and at least a second ocular system, at deployment or in operational working state ocular distances between the first and second ocular systems or relative orientation of the first and second ocular systems arranged to be controllable to change different viewpoints relative to each other;

    the camera system comprising a first and a second camera or multiple secondary cameras designed to create said output signals of different object images of portions of the target object structure or the direct environment thereof based on multiple viewpoint wide baseline imaging, and further comprising an image processing or control arrangement, communicatively coupled to an image acquiring circuitry and configured to process the received signals of the target object image, which cannot be seen by the first camera, and which is under normal working situations not possible with a stereo system,the image processing arrangement being arranged to find corresponding image points between the images from different cameras based on a wide baseline matching system and comprising a computer program code arranged to carry out a turnkey technique to find corresponding regions of object images from separate cameras and to direct the cameras of the imaging system towards a shared working volume,the ocular systems having re-orientable camera heads configured to automatically fine-tune a field of view of the camera heads,wherein a baseline between the first and second ocular systems is arranged to be selectable at deployment or in operational working state in the range 20 to 250 mm, the distance between the ocular systems is arranged to be changeable and wherein the imaging system is configured to determine a configuration or constellation of the camera system fine-tuned using a cognitive control unit and combine the output signals into integrated video data taking into account said configuration or constellation of the camera system, the integrated video data comprising a synthetic overview image, in which generating the synthetic overview image comprises using texture blending with illumination correction on a depth modulated projection surface.
