Many applications require the verification of exact dimensional measurements according to their specified manufacturing tolerances. This process is referred to as ‘gauging’.
A digital camera together with the right vision software tools can easily automate this inspection step for a variety of products and parts. Alignment and gauging can also be used in conjunction with vision guided motion applications. In that case the visual feedback is being used to align mechanical or optical components.
This is an example of a battery clamp inspection. The vision software (NI Vision Builder for Automated Inspection) is automatically locating specific part features, regardless of whether the part has shifted or rotated within the field of view of the camera.
