1. A method of identifying potential construction objects from images, the method comprising: receiving, by one or more computing devices, an image captured by a camera associated with a vehicle as the vehicle is driven along a roadway; converting, by the one or more computing devices, the image into a first channel corresponding to an average brightness contribution from red, blue and green channels of the image; converting, by the one or more computing devices, the image into a second channel corresponding to a contribution of a color from the red and the green channels of the image; and using, by the one or more computing devices, a template to identify a region of the image corresponding to a potential construction object from the first channel and the second channel, wherein the template includes a first inner area that is situated within a second middle area that is situated within a third outer area, and using the template further includes processing image data within both the first inner area and third outer area to identify the region such that data within the second middle area exclusive of the first inner area is ignored.
