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 6):
A method for calibrating a volumetric estimation device for determining dimensions of an object comprising:\n projecting by each of at least a first laser source and a second laser source 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, capturing by a camera 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; measuring the camera distortion effects generating 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 are not collinear and wherein the point of laser projection from at least one of the a first laser source and a second laser source generating projected crosslines 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\n determining, based on locations of laser projected crosslines in camera images, 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.
