Abstract:
A camera vision system for creating 3D reconstructions of objects may include a camera, a distance sensor having a fixed spatial relationship with the camera, and a system controller. The system controller receives distance sensor signals from the distance sensor indicating a sensor-to-object distance, determines a camera-to-object distance and a corresponding camera focus state based on the sensor-to-object distance, and transmits camera focus state control signals to cause the camera to adjust to the camera focus state. The system controller retrieves camera intrinsic parameter values for the camera focus state, transmits image capture control signals to cause the camera to capture an object image of the object, receives object image data from the camera for the captured object image, and stores the object image data and the camera intrinsic parameter values in an image database for use in the 3D reconstruction.
