Abstract:
Disclosed are an apparatus and methods for calibrating a volumetric estimation device for determining dimensions of an object. Described is a first laser source and a second laser source, each projecting at least two laser lines onto an object from a point of laser projection, to form a rectangular calibration target having crossline locations on at least a portion of the object and a camera for capturing an image of the rectangular calibration target projected onto the object, the camera having a camera image plane and a camera image plane centre point. The camera captures the laser projected crosslines as camera images. Means for utilising locations of laser projected crosslines in camera images, means for determining a deviation angle of the laser projection from a direction perpendicular to the camera image plane and the distance between the camera image plane centre point and laser source can allow for laser calibration.

Claim (Index 1):
An apparatus for calibrating a volumetric estimation device for determining dimensions of an object, comprising:\n at least a first laser source and a second laser source, each projecting at least two laser lines onto an object from a point of laser projection, to form a rectangular calibration target having crossline locations on at least a portion of the object, a camera for capturing an image of the rectangular calibration target projected onto the object, the camera having a camera image plane and a camera image plane centre point; a processor configured to calibrate the camera to measure the camera distortion effects to generate a filter to remove the distortion effects so that the camera approximates a pinhole camera model, the camera configured to receive laser light; wherein the camera image plane centre point and the points of projection of the laser sources generating projected crosslines are not collinear; wherein the point of laser projection from at least one of the a first laser source and a second laser source are not collinear with the camera image plane centre point so that at least one of a first distance between the camera image plane centre point and a first laser source and a second distance between the camera image plane centre and a second laser source is unknown; and wherein the processor is further configured to\n utilise locations of laser projected crosslines in camera images to determine a deviation angle from a direction perpendicular to the camera image plane and the distance between the camera image plane centre point and laser source.
