Abstract
From a survey vehicle, two types of data are obtained: images from a camera and reflections from a laser. The laser data is filtered in order to detect assets. The detected assets are then processed to locate and measure the assets. Once this information has been obtained, it is combined with the images captured by the camera in order to recognize the assets.
Claims19
A method for asset inventory using a survey vehicle, the method comprising:
- concurrently capturing images on a camera as said vehicle advances and assigning geographical locations to said images, and emitting a beam of light from a laser mounted on said vehicle and capturing laser data reflected off of various objects;
- detecting an object of interest from said various objects by processing said laser data using at least one parameter unique to said object;
- locating said object of interest geographically by aggregating proximal laser scanned points into a single object and identifying an (X,Y,Z) position thereof;
- measuring said object of interest by approximating object size of said single object;
- and
- recognizing said object of interest by locating said single object in one of said images captured by said camera.

A survey vehicle comprising:
- at least one two-dimensional laser scanning device;
- reception means to capture laser data reflected off various objects;
- at least one camera for capturing images as said vehicle advances;
- a positioning system to attach geographical locations to said images;
- and
- a data capture computer adapted to;
- receive said laser data and said images;
- detect an object of interest from said various objects by processing said laser data using at least one parameter unique to said object;
- locate said object of interest geographically by aggregating proximal laser scanned points into a single object and identifying an (X,Y,Z) position thereof;
- measure said object of interest by approximating object size of said single object;
- and
- recognized said object of interest by computing a location of said single object in one of said image capture by said camera.
