20230236009 · 2023-07-27 · ·

A light source for structured light, comprising a plurality of light source elements arranged in an array, wherein the light source elements are configured to be driven in the following two modes:—a calibration mode, wherein only a part of light source elements are adapted to be driven; and—a normal mode, wherein the rest of the light source elements are adapted to be driven.

DEVICE AND METHOD FOR DETECTING THE SURROUNDINGS OF A VEHICLE

A device for detecting the surroundings of a vehicle and a method for detecting the surroundings, and a vehicle designed to carry out said method comprise a camera module, a camera control apparatus, an analysis unit and an illumination device. The illumination device is formed by a matrix headlight of the vehicle and is designed such that it can project a light pattern into the surroundings. The projected light pattern is imaged in the detection region of the camera module and the 3D position of measurement points formed by the light pattern in the surroundings is determined by the analysis unit. However, the illumination device projects the light pattern only into regions of the surroundings in which the analysis unit has ascertained, based on image data, a value that is critical for 3D position determination.

BORESCOPE WITH PATTERN PROJECTION

A borescope includes an electronic image capture unit having two image capture sensors as a borescope lens at an end of a shaft that is designed for being inserted into a borescope opening, a position and alignment of the image capture sensors in relation to one another being suitable for ascertaining three-dimension (3D) information using triangulation; and a pattern projector configured to project a pattern into a common recording region of the image capture sensors. The pattern projector includes: a fundamentally optically imaging light-guide bundle, which is made up of statistically distributed optical fibers having differing transmittances, to whose input surface a light source is coupled and whose output surface is aligned with the region captured by the image capture sensors.

METHODS FOR OPTICAL TRACKING AND SURFACE ACQUISITION IN SURGICAL ENVIRONMENTS AND DEVICES THEREOF

A computer assisted system is disclosed that includes an optical tracking system and one or more computing devices. The optical tracking system includes an RGB sensor and is configured to capture color images of an environment in the visible light spectrum and tracking images of fiducials in the environment in a near-infrared spectrum. The computer assisted system is configured to generate a color image of the environment using the color images, identify fiducial locations using the tracking images, generate depth maps from the color images, reconstruct three-dimensional surfaces of structures based on the depth maps, and output a display comprising the reconstructed three-dimensional surface and one or more surgical objects that are associated with the tracked fiducials. The computer assisted system can further include a monitor or a head-mounted display (HMD) configured to present augmented reality (AR) images during a procedure.
