Precision Motor Control Using Visual Calibration

logo Calibration

In order to make high precision semi-automated injection, using the microscope’s built-in camera, the field of view of the camera is mapped to the steps of the stepper motor controlling┬áthe injection mechanism.

The camera vision software asks the user to move the stepper motor to two different points and click where they see the tip of the injection nano-pipette. Using the coordinates, the x and y components are mapped to steps of the stepper motors. The camera vision software communicates with the Virtual Instrument to perform the injection.
