Determining object dimension using offset pixel grids

A LIDAR system comprising:

• a light source and a sensor configured to acquire measurement data;
• a processor configured to:
• receive said measurement data and to generate therefrom object pixel data corresponding to measurement of an object, the object pixel data including a plurality of data pixels corresponding to an edge of the object, the plurality of data pixels including at least two pixels adjacent to each other in a first direction where the at least two pixels are offset from each other in a second direction by an offset distance which is less than a dimension of at least one of the at least two pixels in a second direction, where at least one outer pixel of the at least two pixels extends by the offset away from an outer edge of at least one inner pixel of the at least two pixels;
• determine a location of the edge of the object as located within an outer edge of the at least one inner pixel, to truncate an extent of the object from that of the plurality of data pixels.
