Abstract
Vehicle monitoring employs three-dimensional (3D) information in a region adjacent to a vehicle to visually highlight objects that are closer to the vehicle than a threshold distance. A vehicle monitoring system includes a 3D scanner to scan the region adjacent to the vehicle and provide a 3D model including a spatial configuration of objects located within the scanned region. The vehicle monitoring system further includes an electronic display to display a portion of the scanned region using the 3D model and to visually highlight an object within the displayed portion that is located less than the threshold distance from the vehicle.
Claims16
A vehicle monitoring system comprising:
- a three-dimensional (3D) scanner configured to scan a region adjacent to a vehicle, the scan being used to provide a 3D model including a spatial configuration of objects located within the scanned region;
- a 3D electronic display configured to display a portion of the scanned region using the 3D model and to visually highlight an object within the displayed portion that is located less than a threshold distance from the vehicle, the threshold distance corresponding to a zero disparity plane associated with the portion of the scanned region displayed by the 3D electronic display;
- and
- an image processor configured to apply a projective transformation to the 3D model prior to the displayed portion being rendered on the 3D electronic display, the projective transformation being configured to enhance a relative size of the visually highlighted object in comparison to objects in the displayed portion at a distance greater than the threshold distance corresponding to the zero disparity plane and to provide a visual perception of the visually highlighted object as being in front of the zero disparity plane on the 3D electronic display,
- wherein visually highlighting an object is configured to enhance user perception of the object that is closer to the vehicle than the threshold distance.
A three-dimensional (3D) vehicle monitoring system comprising:
- a 3D camera configured to capture a 3D image of a region adjacent to a vehicle;
- an image processor configured to provide a 3D model of the 3D imaged region using the 3D image, the 3D model including a spatial configuration of objects within the 3D imaged region;
- and
- a 3D electronic display configured to display a portion of the 3D imaged region using the 3D model and to visually highlight an object within the displayed portion that is located less than a threshold distance from the vehicle,
- wherein the visually highlighted object is configured to provide collision avoidance when the vehicle is being moved in a direction of the adjacent region.
A method of vehicle monitoring, the method comprising:
- capturing a 3D scan of a region adjacent to a vehicle using a 3D scanner;
- producing a 3D model from the captured 3D scan comprising applying a projective transformation to the 3D model, the 3D model including a spatial configuration of objects located within the scanned region;
- and
- displaying using a 3D electronic display a portion of the scanned region using the 3D model, the projective transformation being applied prior to displaying the scanned region portion on the 3D electronic display,
- wherein displaying a portion of the scanned region comprises visually highlighting an object within the displayed portion at a distance from the vehicle that is less than a threshold distance, the visually highlighted object appearing to be in front of a zero disparity plane of the 3D electronic display corresponding to the threshold distance,
- wherein the visually highlighted object is configured to enhance user perception of the object that is closer to the vehicle than the threshold distance, the projective transformation including a depth compression of the displayed portion to enhance a relative size of the visually highlighted object in comparison to objects in the scanned region at a distance greater than the threshold distance corresponding to the zero disparity plane.
