Abstract
A method and system are provided for controlling a measurement device remotely through gestures performed by a user. The method includes providing a relationship between a command and a gestures. A gesture is performed by the user with the user's body that corresponds to the user gesture. The gesture performed by the user is detected. A command is determined based at least in part on the detected gesture. Then the command is executed with the laser tracker.
Claims19
A method for controlling a measurement device, the method comprising:
- providing a relationship between a command and a gesture, the gesture corresponding to a skeletal model of a body position of a user;
- measuring a three-dimensional coordinate of a point on a surface based on a first light projected from a first light source of the measurement device;
- projecting a second light from a second light source on the user;
- acquiring, with a camera, the body position of the user performing the gesture;
- generating, at a processor, the skeletal model of the body position of the user;
- identifying, at the processor, the gesture performed by the user from the skeletal model of the body position;
- determining, at a processor, the command based on the gesture and the relationship between the command and the gesture;
- and
- executing, by the processor, the command at the measurement device.
A method for controlling a measurement device, the method comprising:
- providing a relationship between a command and a gesture, the gesture corresponding to a body position of the user;
- acquiring, with a camera, an image of a user performing the gesture;
- determining, at a processor, the command based on the gesture and the relationship between the command and the gesture;
- executing, by the processor, the command at the measurement device;
- determining that the user is in the image;
- acquiring with the camera a proceeding image;
- aligning the proceeding image with the image;
- and
- subtracting the image from the proceeding image to identify foreground shapes.
A measurement device, including:
- a first camera configured to measure a three-dimensional coordinate of a point on a surface based on a first light projected from a first light source of the measurement device;
- a projector configured to project a second light from a second light source on the user
- a second camera configured to acquire an image of a user performing a gesture;
- and
- a processor configured to:
- provide a relationship between a command and a gesture, the gesture corresponding to a skeletal model of a body position of the user;
- generate the skeletal model of the user;
- identify the gesture performed by the user from the skeletal model of the body position;
- determine the command based on the gesture acquired by the camera and a relationship provided between the command and the gesture, and
- execute the command at the measurement device.
