Abstract: The invention relates to a method for generating a chapter structure constructed from individual chapters (no. 1, no. 2, no. 3, . . . ) for video data from a video data stream containing images captured in successive image frames from an object area of a surgical microscope, for which different operating states can be set. Here, an item of chapter information is determined for some of the successive image frames, and the successively captured image frames of the video data stream are classified in a chapter (no. 1, no. 2, no. 3, . . . ) of the chapter structure depending on the chapter information determined for some of the image frames. The chapter information is determined taking into account meta data containing an item of operating state information relating to the surgical microscope.

Abstract: A surgical microscope comprises microscopy optics, a camera, a display system and a controller comprising a data memory storing object data of at least one surgical tool. The microscopy optics are variable optics for changing an imaging scale of an imaging of a field of view onto the camera. The controller is configured to process the camera images and to identify the at least one tool in the camera images by object recognition using the object data of the at least one tool and the set imaging scale.

Abstract: A method for determining a surface topography of a body includes the following steps: recording a stereoscopic image of the surface of the body with an image recording device; and, generating a topography data set from the stereoscopic image in a coordinate system set by the image recording device. The invention further relates to apparatuses for determining a surface topography of a body in a coordinate system fixed in space and/or a coordinate system fixed on the body.

Abstract: A microscope system includes a microscope for generating a microscopic image of an observation region to be examined and a display unit for visualizing the microscopic image. The system further includes a registration unit and an evaluation unit. The registration unit is configured to register the three-dimensional structure of an observation object from available data to the position of the observation object in the observation region. The evaluation unit is configured to calculate a depth preview map of the three-dimensional structure of the observation object from available data and to transmit the depth preview map to the display unit for visualizing the three-dimensional structure in relation to the position of the observation object in the observation region.

Abstract: The invention relates to a method for the image-based calibration of multi-camera systems with adjustable focus and/or zoom, including the following method steps: calculating a number of beams from an optics simulation for different focus and/or zoom settings or combinations of focus and zoom settings; reading out the focus and/or zoom settings and storing these values with the beams such that a unique assignment is ensured; parameterizing a continuous pinhole camera model for extrinsic and intrinsic calibration of different zoom and/or focus settings of the multi-camera system on the basis of the data from the optics simulation.

Abstract: A microscope system (1) includes a microscope and a camera (3) for generating and recording image-based information on an area of observation. A storage and evaluation unit (4) is connected to the microscope (2) and the camera (3) for detecting parameter settings of the microscope associated with the image-based information. A display (5) renders visible the digital image of the area of observation, and a control unit (6) is connected to the storage and evaluation unit (4) and to the display (5). The control unit (6) places digital markers for marking observed objects in a digital image of the area of observation and displays the digital markers on the display (5). The storage and evaluation unit (4) selects and stores information on each digital marker so that the marker can be associated at a later point in time with the position of the observed object.
