Claim One:
1. A method of identifying potential construction objects from images, the method comprising: receiving, by one or more computing devices having one or more processors, 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 first template moving in a sliding window pattern over the image to identify a region of the image from the first channel and the second channel, wherein the first template includes a first area and identifying the region further includes determining from the first channel that image data within the first area of the first template corresponding to the region meets a brightness threshold value such that the region is identified as a potential construction object and wherein the first area is a first inner area that is situated within a second middle area of the first template that is situated within a third outer area of the first template and identifying the region further includes determining from the second channel whether a difference in image data values between the first inner area and the third outer area meets a threshold color value.
