Systems and techniques for performing a scan-free reading of a structured identifier are provided. One technique involves obtaining a first set of images of an object within a scanning volume of an environment. The object is passed through the scanning volume without an explicit presentation of the structured identifier to an optical scanner within the environment. For each image of a plurality of the first set of images, an indication of a first region of interest of the structured identifier on the object within the image is obtained, based in part on a second set of images of the object having a lower quality than the first set of images. The first region of interest of the structured identifier is extracted from a first image of the plurality of the first set of images. The structured identifier within the first region of interest within the first image is decoded.

Scan-free barcode reading

Image data from a camera is used to identify one or more items in a dynamic field of view for item identification and tracking. The camera focus setting may be adjusted to different depth of field based on estimated distances to the items within the image data. After adjusting the focus setting, additional image data may be collected to capture a sharper image of the item and ensure sufficient clarity for item recognition based on item identifiers visible on the items within the image data.

High speed continuously adaptive focus and deblur

Features are disclosed for providing guidance regarding robotic traffic density to humans working in the same physical area as robots. Through analysis of the planned and/or historical routes of the robotic traffic, traffic densities can be identified for the physical area. The densities may be used to generate a heat map or other visual display for presentation to human workers. This allows the workers to move through the physical area with a better understanding of where robot traffic is dense and how to best avoid interrupting those assets.
