Yield Mapping with Digital Aerial Color Infrared (CIR) Images

1999-09-14
1999-01-2847
Yield potential was predicted and mapped for three corn fields in Central Illinois, using digital aerial color infrared images. Three methods, namely statistical (regression) modeling, genetic algorithm optimization and artificial neural networks, were used for developing yield models. Two image resolutions of 3 and 6 m/pixel were used for modeling. All the models were trained using July 31 image and tested using images from July 2 and August 31, all from 1998. Among the three models, artificial neural networks gave best performance, with a prediction error less than 30%. The statistical model resulted in prediction errors in the range of 23 to 54%. The lower resolution images resulted in better prediction accuracy compared to resolutions higher than or equal to the yield resolution. Images after pollination resulted in better accuracy compared to images before pollination.

Yield Mapping of Soybeans and Corn Using GPS

Data obtained when harvesting with a combine equipped with a yield monitor were used to develop yield maps. A prototype yield monitor was developed that uses a combination of light emitters and receivers mounted in a rectangular frame. The monitor was mounted in the combine in the top of the clean grain elevator. As grain flows through the monitor, a voltage change proportional to light reduction was recorded. This voltage was then correlated to grain flow rate. At the same time, site-specific location was recorded using the global positioning satellites (GPS) system. The location data, yield monitor output, cutting width, and combine forward speed were stored in a spreadsheet format. The data were then used to prepare the yield maps.

Weed Recognition Using Machine Vision and Color Texture Analysis

1996-08-01

The environmental impact from herbicide utilization has been well documented in recent years. The reduction in weed control with out a viable alternative will likely result in decreased per acre production and thus higher unit production cost. The potential for selective herbicide application to reduce herbicide usage and yet maintain adequate weed control has generated significant interest in different forms of remote sensing of agricultural crops. This research evaluated the color co-occurrence texture analysis technique to determine its potential for utilization in crop groundcover identification. A program termed GCVIS (Ground Cover VISion) was developed to control an ATT TARGA 24 frame grabber; and generate HSI color features from the RGB format pixel data, HSI CCM matrices and the co-occurrence texture feature data.

Web-Based Vehicle Remote Access and Its Application to In-Vehicle Network Integrated Fleet Management

The demands for effective and efficient management of commercial vehicles and freight transport have led to the increasing needs for sophisticated fleet management systems (FMS) for reducing the operation cost of commercial vehicle operation, improving custom service and asset management as well as maintaining the safety and security. The availability and declining costs of telecommunications and information technologies afford opportunities for using real-time information to achieve these targets and the emergence of internet technology make it possible to transfer updated real-time information through more widely available communication media. This paper introduces the web-based remote-access concept for the real-time information acquisition, which has been used to enhance functionality of a dynamic fleet management system.
