Embodiment Construction

[0029] According to the teachings herein, an orientation tracking system can be provided that can measure the orientation of a movable target object in an absolute coordinate system after the motion is completed, eg incrementally tracked using a position encoder. If the absolute coordinate measurement system determines that the current orientation of a temporarily stationary target object deviates from the desired orientation by more than a configurable tolerance, the target object can be commanded to move towards the corrected orientation. Therefore, errors in relative coordinate measurements can be corrected using the absolute coordinate measurement process disclosed herein.

[0030] One example of an incremental motion measurement system is a system based on dead reckoning odometry. Any dead reckoning based scheme will have measurement inaccuracies as small errors will accumulate over time. Measurement inaccuracies can be caused by systematic errors in the device, or by di...

Abstract

The automated process uses a local positioning system to obtain position (ie, position and orientation) data for one or more movable target objects. Where the target object has the ability to move under computer control, the automated process can use measured orientation data to control the position and orientation of such target object. The system utilizes the measurement and image capture capabilities of local positioning systems and integrates controllable marker lights, image processing, and coordinate transformation calculations to provide tracking information for vehicle orientation control. The resulting system is capable of tracking the position and orientation of objects within a frame of reference.

Description

technical field [0001] The present disclosure generally relates to systems and methods for tracking the orientation of a movable target object, such as a tracked vehicle or other electromechanical machine guided by a computer program, as it moves relative to a workpiece or part. Background technique [0002] Applications involving manufacturing processes using tracked vehicles or other computer-controlled electromechanical machines often employ orientation tracking within a frame of reference. Existing orientation tracking solutions can be divided into two categories: absolute motion tracking and incremental motion tracking. Absolute motion tracking involves tracking a position and / or orientation defined within a reference frame, such as an aircraft frame. Known technologies for absolute motion tracking include optical motion capture, laser tracking, depth cameras, magnetic tracking, and acoustic wave-based tracking. [0003] Incremental motion tracking measures displaceme...
