QUALITY ASSURED MANUFACTURING
First Claim
1. A tool location system for a handheld tool in a manufacturing environment where a workpiece is manufactured, the tool comprising:
- a camera for capturing images; and
a numerical evaluator means configured to determine a tool-location of the tool by a simultaneous location and mapping (SLAM) navigation calculation based on the images from the camera;
wherein the tool-location is determined with respect to a global coordinate system in relation to the manufacturing environment from portions of the images which comprise a view of the manufacturing environment, andwherein the tool-location is determined with respect to a local coordinate system in relation to the workpiece from portions of the images which comprise a view of the workpiece,

Abstract
The invention relates to a tool location system for a handheld tool in a manufacturing environment, wherein the tool is equipped with a camera for capturing images. According to the invention, the location system comprises numerical evaluator means, which is built to determine a tool-location of the tool by a simultaneous location and mapping (SLAM) navigation calculation based on the images from the camera. Therein the tool-location is determined with respect to a global coordinate system in relation to the manufacturing environment from portions of the images which comprise a view of the manufacturing environment and the tool-location is determined with respect to a local coordinate system in relation to the workpiece from portions of the images which comprise a view of the workpiece.

14. A method for locating a handheld tool in a manufacturing environment where a workpiece is manufactured, wherein the tool is equipped with a camera for capturing images, the method comprising:
-
determining a tool-location of the tool by a SLAM navigation calculation based on the images from the camera, that further comprises; determining the tool-location with respect to a global coordinate system in relation to the manufacturing environment from portions of the image which comprise a view of the manufacturing environment, and determining the tool-location with respect to a local coordinate system in relation to the workpiece from portions of the image which comprise a view of the workpiece; wherein the local coordinate system is moving with respect to the global coordinate system. - View Dependent Claims (15, 16)

18. One or more non-transitory computer-readable media storing one or more programs that are configured, when executed, to cause one or more processors to execute a SLAM navigation algorithm based on images from a camera at a tool in a manufacturing environment in which a workpiece is manufactured, with a moving workpiece in an assembly line configuration, wherein a location of the tool is established:
-
with respect to a global coordinate system relative to the environment by portions of the images depicting the environment and also with respect to a local coordinate system relative to the workpiece by portions of the image depicting the workpiece.
