Abstract: This disclosure relates to a system for monitoring walls. The system receives first and second image data representing two-dimensional locations of multiple points of the wall associated with a first and second point in time, the second point in time being later than the first point in time. The system also receives depth data from a depth sensor indicative of a change in depth of the wall between the first point in time and the second point in time. The system then determines data indicative of a change of the two-dimensional locations of the multiple points of the wall between the first point in time and the second point in time based on the first image data, the second image data, and the depth data. This means correlations between the image data and the depth data can be considered, which allows accurate perpendicular line of sight monitoring.

Abstract: The present invention provides a system and method (400) of generating a three-dimensional model of an object. The method (400) includes capturing first image and range data corresponding to a first portion of the object from at least two different positions (step 405) and generating a first three-dimensional model of the first portion of the object using the first image and range data (step 410). The method further includes capturing second image and range data corresponding to a second portion of the object from at least two different positions and generating a second three-dimensional model of the second portion of the object using the second image and range data (step 415). The first and second portions are overlapping. Finally, a third three-dimensional model is generated describing the first and second portions of the object by combining the first and second three-dimensional models into a single three-dimensional model (step 420).

Abstract: The disclosed invention relates to a system for and a method of providing a collision warning to an operator of a vehicle. The disclosed system, which is operable in accordance with the disclosed method, includes a range gated visual imaging means and a processing means. The imaging means is operable to acquire a visual image of an object located within a detection zone whose location relative to the vehicle is known. The processing means is operable to process the image to determine the location of the object relative to the vehicle, determine whether the vehicle might collide with the object, and warn the operator if it is determined that the vehicle might collide with the object.
