System and method for measuring irregular objects with a single camera
First Claim
1. An optical system for measuring an irregularly shaped object, the system comprising:
- a dimensioning station including a base and a first wall extending from the base;
a first collimated light source, a first collimated light passing from the first collimated light source generally parallel to the base, illuminating the first wall, and defining a shadow, anda camera arranged to obtain image data representing the shadow,wherein the system is configured to collect the image data for determining at least one dimension of an object.

Abstract
An optical system for measuring an irregularly shaped object includes a dimensioning station having a base, a first wall extending from the base, and a second wall extending from the base. A collimated light is passed from each of first and second collimated light sources arranged generally parallel to the base, illuminating the first and second walls and defining first and second shadows, respectively. A camera is arranged to obtain image data representing each of the first and second shadows. The system is configured to collect the image data for determining at least one dimension of an object from each of the first and second shadows. Each of the first and second collimated light sources may be a light with a collimating lens arranged between the light and the respective wall. The light source may be an LED and the collimating lens may be a collimating Fresnel lens.

17. A method of measuring an irregularly shaped object, the method comprising:
-
providing a dimensioning station including a base and a first wall extending from the base; illuminating the first wall with a first collimated light arranged generally parallel to the base; placing an object to be measured on the base; and measuring a size attribute of a first shadow formed on the first wall by the first collimated light and the object to be measured. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
