Software library for tracked ultrasound image acquisition, calibration, and processing.
Generic Sensor tracker

This device allows you to collect sensor data from sensors with drivers compliant with the Windows Sensor and Location platform.

Supported sensors

For now, this device can handle the following type of sensors:

  • accelerometer
  • gyrometer

The sensor drivers must be compliant with the Windows Sensor and Location platform.

The following sensors have been tested:

  • STMicroelectronics 3-axis Accelerometer

Supported platforms

Windows version: >= 7

Installation

Install the sensor drivers if not installed by default on the target platform.

        • Accelerometer Raw sensor measurement. The values are stored in the translation part of the transformation matrix. The rotation part is identity.
        • Gyrometer Raw sensor measurement. The values (angular velocity in degrees/s) are stored in the translation part of the transformation matrix. The rotation part is identity.
