  • Patent number: 11030436
    Abstract: A method of recognizing an object includes comparing a three-dimensional point cloud of the object to a three-dimensional candidate from a dataset to determine a first confidence score, and comparing color metrics of a two-dimensional image of the object to a two-dimensional candidate from the dataset to determine a second confidence score. The point cloud includes a color appearance calibrated from a white balance image, and the color appearance of the object is compared with the three-dimensional candidate. The first or second confidence score is selected to determine which of the three-dimensional candidate or the two-dimensional candidate corresponds with the object.

  • Publication number: 20210104071
    Abstract: A deep learning method employs a neural network having three sub-nets to classify and retrieve the most similar 3D model of an object, given a rough 3D model or scanned images. The most similar 3D model is present in a database and can be retrieved to use directly or as a reference to redesign the 3D model. The three sub-nets of the neural network include one dealing with object images and the other two dealing with voxel representations. Majority vote is used instead of view pooling to classify the object. A feature map and a list of top N most similar well-designed 3D models are also provided.

  • Patent number: 10872178
    Abstract: In an example implementation, a method of processing a 3D object includes receiving a 3D object model representing a new 3D object to be processed. The method includes computing attributes of the object and comparing the object attributes with stored object attributes from previously processed 3D objects. When the comparison provides a match between the object attributes and stored object attributes, then a print recipe associated with the matching stored object attributes is retrieved.

  • Patent number: 9710926
    Abstract: A system and method for processing an image of a retail shelf area. According to one aspect, a portion of an image that depicts the retail shelf area at an angled and depthwise perspective is determined to depict shelves. The image can be modified so that the portion of the image determined to depict shelves is substantially parallel to a predefined horizontal reference frame. Products can then be detected in the remainder portion of the image, separate from the portion of the image determined to depict shelves. An applicable planogram can be used to generate compliance information based on the detected products and the determined portion of the image depicting shelves.
