Abstract
A sensing apparatus for a host vehicle or the like, the apparatus comprises sensing means arranged to capture a first dataset of digital data comprising a set of data points representative of an image of a scene around the host vehicle, said image including at least one salient feature; first data processing means arranged to identify a subset of the data points which correspond to the at least one salient feature, and second data processing means arranged to apply a transformation to the subset of data points to produce a processed subset which corresponds to a digital image of the salient features in the scene that has been corrected for at least one type of distortion in the image.
Claims7
A sensing apparatus for a host vehicle comprising:
- sensing means arranged to capture a first dataset of digital data comprising a set of data points representative of an image of a scene around the host vehicle, said image including at least one salient feature;
- first data processing means arranged to identify a subset of said data points which correspond only to said at least one salient feature;
- and
- second data processing means arranged to apply a transformation to said subset of data points to produce a processed subset which corresponds to a digital image of said salient features in said scene that has been corrected for at least one type of distortion in said image.
A method of determining the position of salient features within a scene in an image around a host vehicle comprising:
- (a) capturing a first dataset of digital data comprising a set of data points representative of an image of a scene ahead of said host vehicle, said image including at least one salient feature;
- (b) identifying a subset of said data points which correspond only to said at least one salient feature;
- and
- (c) applying a transformation to said subset of data points to produce a processed subset which corresponds to a digital image of said at least one salient feature in said scene that has been corrected for at least one type of distortion in said image.
A non-transitory computer readable medium comprising a set of program instructions which, when running on a processor of a vehicle-mounted image processing apparatus that is arranged to receive signals from a host vehicle mounted image capture device, cause said apparatus to:
- (a) capture a first dataset of digital data comprising a set of data points representative of an image of a scene around said host vehicle as captured by said image capture device, said image including at least one salient feature;
- (b) identify a subset of said data points which correspond to only said at least one salient feature;
- and
- (c) apply a transformation to said subset of data points to produce a processed subset of data points which corresponds to a digital image of said at least one salient features in said scene that has been corrected for at least one type of distortion in said image.
