Abstract
This assistance method is intended for assisting an operator in performing a task on a product (12). To that end, the method comprises a step of displaying, superimposed on a view of a scene including a monitored part of the product (12) on which a subtask of the task has to be performed, at least one assistance image (100, 136) intended to assist the operator in performing this subtask. Said at least one assistance image (100, 136) includes at least one highlighting image (100, 102) highlighting the monitored part.
Claims25
An assistance method for assisting an operator in performing a task on a product, the method comprising a step of displaying, superimposed on a view of a scene including a monitored part of the product on which a subtask of the task has to be performed, at least one assistance image intended to assist the operator in performing this subtask, characterized in that said at least one assistance image includes at least one highlighting image highlighting the monitored part, wherein the view of the scene is provided by a view source, and the method further comprises the following steps:
- tracking a displacement of the view source from a first viewing position in the scene, in which the product occupies a first relative position with a first relative orientation relatively to the view source, toward a second viewing position in which the product occupies a second relative position with a second relative orientation relatively to the view source,
- calculating an estimation of the second relative position and of the second relative orientation from the first relative position and orientation and from the tracked displacement, and
- refreshing the display of the at least one assistance image so as to adjust said at least one assistance image to the estimation of the second relative position and orientation,
- wherein the first viewing position consists of an initial viewing position in which the first relative position and orientation consist of predetermined relative position and orientation known by a display management unit in charge of displaying the at least one assistance image,
- wherein the method further comprises a step of equipping the product with a support comprising a slot able for receiving the view source and adapted so that, when the support is equipped on the product and the view source is received in said slot, the view source is placed in said initial viewing position, followed by a step of placing the view source in the slot of said support.
An assistance system for assisting an operator in performing a task on a product, the assistance system comprising a display management unit configured for displaying, superimposed on a view of a scene including a monitored part of the product on which a subtask of the task has to be performed, at least one assistance image intended to assist the operator in performing this subtask, characterized in that said at least one assistance image includes at least one highlighting image highlighting the monitored part,
- wherein the assistance system includes a view source, at least one sensor to track a displacement of the view source from a first viewing position in the scene, in which the product occupies a first relative position and a first relative orientation relatively to the view source, toward a second viewing position in which the product occupies a second relative position and a second orientation relatively to the view source, and the display management unit is configured to calculate an estimation of the second relative position and orientation from the first relative position and orientation and from the tracked displacement, and to refresh the display of the at least one assistance image so as to adjust said at least one assistance image to the estimation of the second relative position and orientation,
- wherein the first viewing position consists of an initial viewing position in which the first relative position and orientation consist of predetermined relative position and orientation known by the display management unit,
- the system further comprising a support able to be mounted on the product and including a slot able for receiving the view source, said support being adapted so that, when it is mounted on the product and the view source is received in said slot, the view source is placed in the initial viewing position.
