摘要:
Novel tools and techniques that can be used to enhance the effectiveness of photogrammetric tools, such as bundle adjustment. One set of techniques can include a photo-observable backsight operation, in which a position of target point can be observed non-photographically, and this observed position can be used to constrain a pixel coordinate location of the same target point in a bundle adjustment operation. Using another technique, a photo-observable check shot operation, the observed position of another target point can be used to verify the validity of a bundle adjustment calculation. Such techniques can be used together or separately.
摘要:
Novel solutions for position measurement, including without limitation tools and techniques that can be used for land surveying and in similar applications. One such tool is a greatly enhanced position measurement system that takes the form of a surveying rod with substantial independent functionality, which can be used with or without a total station or similar device.

In some embodiments, a crop feeler system automatically executes a navigational task based on a proximity of a vehicle to an obstacle. The crop feeler system includes a hub attached to the vehicle. Inside the hub are two oscillating circuits each having an oscillating frequency. A member is coupled to the hub. Two inductive elements are positioned within the member so that, when the obstacle comes into contact with the member, at least one of the inductive elements moves closer to at least one of the oscillating circuits and alters the oscillating frequency of that oscillating circuit. A navigation sensor measures the oscillating frequency of the oscillating circuit, identifies a navigational task using the oscillating frequency of the oscillating circuit, and executes the navigational task.

Automatic change propagation in an area-based open pit mine designer is disclosed. One example includes an economic shell receiver module to receive an economic shell. In addition a user input module receives a user parametric input denoting an open pit mine shape based on the economic shell. An open pit mine designer module automatically develops an open pit mine design from the user parametric input. The user input module receives an additional area to be incorporated into the open pit mine design. The open pit mine designer module automatically propagates the additional area into the open pit mine design to generate a modified open pit mine design.

A system for collaborative three-dimensional (3D) modeling in a browser application is stored as instructions on a computer-readable medium. The instructions include a browser interface module that executes on the one or more processors to receive user commands from the browser application for modifying a 3D model and cause a rendering of the 3D model to be displayed in a window controlled by the browser application. The instructions further include a modeling engine module that executes on the one or more processors to interpret model data corresponding to the 3D model to generate the rendering of the 3D model, and modify the model data in accordance with the received user commands. Still further, the instructions include a collaboration module that executes on the one or more processors to cause the modified 3D model to be synchronized in real time between the first computing and a second computing device at which the 3D model is being concurrently developed, where the first computing device and the second computing device operate independently of each other on a communication network.

Functional extensions are provided for use with a modeling software. The functional extensions provide functionality not otherwise provided by the modeling software. The functional extensions are received from a client device by a server and stored in a database. Thereafter, the server transmits the functional extensions to a second client device, sometimes in response to receiving a request for the functional extension from the second client device. The server may update a user profile to indicate that a functional extension was received from a user operating the client device and, additionally, may transmit the functional extension to the second client device when the server receives an indication that the user is operating the second client device.

Features of a 3D modeling software application are controlled based on a subscription status of a user. A user having an active subscription status is provided with 3D modeling functions that include functions for creating, inspecting, and modifying 3D models. If the user's subscription status changes to an expired status, the user is provided with at least one of the 3D modeling functions that was provided during the active subscription and is prevented from using at least one other of the 3D modeling functions that was provided during the active subscription.

Sugar cane harvester automatic cutter height control systems maintain consistent cutter heights even as a harvesting machine traverses changing field conditions. After an operator chooses an initial cutting height the automatic systems maintain that height even as ground conditions change.
摘要:
Here presented is information pertaining to water erosion management incorporating topography, soil type, and weather statistics. Also presented is a manner of exchanging water allocation credits. A method of dealing with crop treatment compatibility and a system of estimating crop characteristics are also set forth. Finally, a manner for wide-area agricultural monitoring and prediction is discussed.
