3-dimensional vision system for stitching along a predetermined path
Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate 3-dimensional vision systems that may enable operations on non-flat objects and paths. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.
1. A system for 3-dimensional vision-assisted sewing operations, the system comprising:
a guiding apparatus configured to perform actions along one or more predetermined paths;
a 3-dimensional vision system wherein the 3-dimensional vision system is configured to direct the guiding apparatus to avoid performing an operation on a non-processable feature of an operational object based on at least the 3-dimensional vision system detecting the non-processable feature; and
an operational area.
2. The system of claim 1 , wherein the 3-dimensional vision system is configured to adjust the one or more predetermined paths based at least on one or more detected errors, wherein the errors comprise at least one of: deformation of a substrate, deformation of a patch, deformation of an operational object, translations of an operational object introduced by an operation of the guiding apparatus, rotations of an operational object introduced by an operation of the guiding apparatus, and variation in a spatial dimensions of an operational object.
3. The system of claim 1 , wherein the 3-dimensional vision system comprises a stereoscopic camera.
4. The system of claim 1 , further comprising a tacking system.
5. The system of claim 1 , further comprising a patch library system.
6. A computer implemented method for utilizing a guiding apparatus having a 3-dimensional vision system, the method comprising:
capturing, by the 3-dimensional vision system, a plurality of images of a substrate in an operational area of the guiding apparatus under a range of illumination and image capture parameters wherein the 3-dimensional vision system is configured to direct the guiding apparatus to avoid performing an operation on a non-processable feature of an operational object based on at least the 3-dimensional vision system detecting the non-processable feature;
capturing, by the 3-dimensional vision system, 3-dimensional features of the substrate; and
determining, by the 3-dimensional vision system, visual feature information of a substrate, based at least on the plurality of images and 3-dimensional features.
7. The method of claim 6 , further comprising:
saving the visual feature information to a patch library system, the patch library system configured to store visual feature information in a non-transient computer readable medium.
8. The method of claim 6 , further comprising:
performing an action on an operational object disposed on a surface of the substrate.
9. The method of claim 8 , wherein the operational object is a patch; and wherein the action is sewing the patch to the substrate.
10. The method of claim 9 , further comprising:
performing a tacking operation to secure the patch to the substrate prior to sewing the patch to the substrate.
11. A guiding apparatus comprising:
a 3-dimensional vision system wherein the 3-dimensional vision system is configured to direct the guiding apparatus to avoid performing an operation on a non-processable feature of an operational object based on at least the 3-dimensional vision system detecting the non-processable feature; and
an operational area;
wherein the guiding apparatus is configured to perform actions along one or more predetermined paths.
12. The guiding apparatus of claim 11 , further comprising a patch library.
13. The guiding apparatus of claim 11 , further comprising a multi-patch multi-view system.
