Abstract

Fixed segmented lattice planning for a mobile automation apparatus is provided. A mobile automation apparatus is provisioned with a plurality of segments for a plurality of paths through an environment, each of the plurality of segments being fixed in a reference frame, the plurality of segments arranged in a lattice configuration, with adjacent segments defining fixed nodes in the lattice configuration. The apparatus navigates through the environment on a segment-by-segment basis, storing control inputs and error signals for each segment and then later, when again navigating a segment using stored control inputs and error signals to generate current control inputs, along with current error signals, and storing the current control inputs and the current error signals. Indeed, each time the apparatus navigates a segment in the lattice configuration, the control inputs and the error signals are updated to refine navigation through the environment at each navigation through a segment.

Abstract

First and second photodetectors having first and second collection areas receive return laser light that is reflected and scattered from a target, and generate first and second analog electrical output signals having first and second magnitudes. The second collection area is in close proximity to the first collection area. The first output signal is processed to obtain information related to the target. The first and the second output signals are processed, preferably by determining a ratio of the second magnitude to the first magnitude. A working distance to the target is determined based on the determined ratio. One or more reading parameters by which the target is electro-optically read are adjusted based on the determined working distance.

A radio is capable of communicating with a wireless network. A processor activates the radio in the mobile device. The processor generates an environmental profile of the mobile device based at least on the sensor signal. A memory is coupled to the processor for storing the environmental profile. The processor deactivates the radio when the environmental profile indicates that the rate of motion of the mobile device is above a predetermined threshold for a first period of time. The processor reactivates the deactivated radio when the environmental profile indicates that the rate of motion of the mobile device is below the predetermined threshold for a second period of time.

Abstract

A method of object detection includes obtaining a set of images depicting overlapping regions of an area containing a plurality of objects. Each image includes input object indicators defined by input bounding boxes, input confidence level values, and object identifiers. The method includes identifying candidate subsets of input object indicators in adjacent images. Each candidate subset has input overlapping bounding boxes in a common frame of reference, and a common object identifier. The method includes adjusting the input confidence levels for each input object indicator in the candidate subsets; selecting clusters of the input object indicators satisfying a minimum input confidence threshold, having a common object identifier, and having a degree of overlap satisfying a predefined threshold; and detecting an object by generating a single output object indicator for each cluster, the output object indicator having an output bounding box, an output confidence level value, and the common object identifier.

Abstract

Three-dimensional (3D) imaging systems and methods for segmenting and tracking package walls in commercial trailer loading are described. A 3D-depth camera is oriented in a direction to capture 3D image data of a vehicle storage area. A first portion of the 3D image data is captured by the 3D-depth camera during a first time period and a second portion of the 3D image data is captured by the 3D-depth camera during a second time period. A segmentation application (app) determines, based on the 3D image data, a first data wall slice corresponding to a first package wall and a second data wall slice corresponding to a second package wall, where each of the first package wall and the second package wall is defined by a plurality of packages each having a respective similar depth dimension and each packed within the vehicle storage area during a respective time period.

Abstract

Three-dimensional (3D) depth imaging systems and methods are disclosed for use in commercial trailer loading. In various aspects, a 3D-depth camera is configured and oriented in a direction to capture 3D image data of a vehicle storage area. A depth-detection application (app) executing on one more processors determines, based on the 3D image data, a void data region, and a floor data region within the 3D image data. Based on the determination of the void data region and the floor data region, the depth-detection app generates an out-of-range indicator that indicates that a wall (e.g., a package wall) situated at a rear section of the vehicle storage area is not detected. The determination that a package wall is not detected causes a dashboard app to modify a graphical representation of the capacity of the vehicle storage area.

Abstract

A system and method for density-based RFID network configuration. In various aspects, an RFID reader executes a read cycle defined by dwell times for a low RFID tag density and a high RFID tag density setting. Accordingly, a controller may cause the RFID reader to implement one or more RFID protocols. The controller may then receive data corresponding to the RFID tags from the RFID reader to determine a number of RFID tags within read range of the RFID reader. Based on the number of RFID tags, the controller may determine an adjustment to the read cycle executed by the RFID reader. The controller may then configure the RFID reader to execute the adjusted read cycle.
