Abstract: System and method for a computer vision technique for contactless measurement of vehicle toe are disclosed herein. The method includes capturing with a stereo camera an image containing a vehicle's wheel, segmenting the image, determining a suitable circular component of the wheel and computing the angle of the wheel relative to the camera and, subsequently, to the body of the vehicle. The method includes repeating the process for a plurality of wheels and computing the toe angle of the vehicle based on the obtained results.

Abstract: A computerized system for calibrating vehicle part measurements utilizes tire-based scale calibration with image processing and geometric compensation capabilities. The system automatically determines estimated tire size data from tire images using consensus-based algorithms, extracts actual tire specifications through optical character recognition, and calculates scale calibration data for converting pixel measurements to physical units. Geometric distortion detection and compensation handle angular misalignments between camera and tire planes. Real-time continuous calibration adapts to changing conditions during vehicle inspection operations. The calibration data integrates with defect detection and severity classification systems to enable accurate physical measurements of vehicle components and defects, providing calibration accuracy within 2% across varying operating conditions while accommodating diverse tire types and operational scenarios.

Abstract: There is provided a method of image processing for detection of damage on a vehicle, comprising: accessing time-spaced image sequences depicting a region of a vehicle, captured by image sensors positioned at different heights and/or angles relative to the vehicle, identifying candidate regions of damage in the time-spaced image sequences, performing multi-level redundancy validation by: executing spatial correlation between images captured by different images sensors at different heights and/or different angles, executing temporal correlation between consecutive images captured by each image sensor, and validating persistence of each candidate region of damage across a threshold number of consecutive frames, identifying redundancy in the candidate regions of damage corresponding to a common physical location of the vehicle denoting a single physical damage region based on the multi-level redundancy validation, and providing an indication of the common physical location of the vehicle corresponding to the sing

Abstract: Methods and apparatus for dermatological laser treatment, e.g. for the removal of unwanted tattoos or other skin pigmentation. Removal of multiple colors with a single pulsed laser beam may be achieved using intensities in excess of about 50 GB/cm2. Methods for reducing the pain and tissue damage associated with laser tattoo removal include using a spot size of less than 2 mm with a fluence in the range of 0.5-10 J/cm2. Scanning the laser beam over an area of skin to be treated allows such areas to be treated accurately with scanning patterns calculated to promote rapid dissipation of heat away from treated portions of the skin. Multiple treatment rooms may be served by a single pulsed treatment laser by beam toggling, splitting or pulse-picking to minimise downtime of the laser.

Abstract: An optical system and method are presented for use in measurements on an upper surface of a layered sample when located in a measurement plane. The optical system is configured as a normal-incidence system having an illumination channel and a collection channel, and comprises an objective lens unit and a light propagation affecting device. The objective lens unit is accommodated in the illumination and collection channels, thereby defining a common optical path for propagation of illuminating light from the illumination channel toward an illuminating region in the measurement plane and for propagation of light returned from measurement plane to the collection channel. The light propagation affecting device comprises an apertured structure located in at least one of the illumination and collection channels, and configured to provide angular obscuration of light propagation path for blocking angular segments associated with light propagation from regions outside the illuminated region.
