Size and color are two important indexes to measure the external quality of apples. The current apple size and color detection methods are mostly designed on PC platform, which are difficult to be popularized to smaller companies and growers for the high expense. This research designed and implemented a novel detection system based on embedded platform that covers full function of apple size and color detection but with much lower cost. The hardware of system was mainly composed of ARM11 processor, CMOS camera and stepping motor. The real-time image of apple was acquired by CMOS camera and diameter value was extracted from image as index of size after image preprocessing. Considering that HSI color model is more close to human visual perception than RGB color model, the RGB image acquired by the CMOS camera was transformed to HSI color model. The H component was calculated to determine the percents of red component, which was used for color grading of apple. Preliminary experiments show that the average detection time is 300ms, color detection accuracy is 90% and size (60∗60 pixel) detection accuracy is 93%, respectively. Compared with the traditional apple detection system, this system has the advantages of higher detection speed, lower cost, and smaller size. It will have a good prospect of application in apple quality detecting areas.

IEEE International Workshop on Intelligent Robots and Systems (IROS)

作者： T. Hoeniger Department of Computer Science Institute for Process Control and Robotics University of Karlsruhe Karlsruhe Germany

An intelligent robot control scheme is presented which enables a cooperative work of humans and robots through direct contact interaction in a partially known environment. The control of the degrees of freedom of the manipulator is shared through a hybrid controller between the operator and the intelligent control system. The allocation of the control among human and robot occurs dynamically according to the state of the task execution and the capabilities of the human and the robot. Experiments were conducted to prove the effectiveness of our concept.

IEEE International Symposium on Assembly and Manufacturing (ISAM)

This paper presents a new approach to optimized notion planning for industrial robot arms with six degrees of freedom in an online given 3D environment. The method is based on the A*-search algorithm and needs no essential off-line computations. The algorithm works in an implicitly discrete configuration space. Collisions are detected in the Cartesian workspace by hierarchical distance computation based on the given CAD model. The collision-free result path is then optimized in execution time using rounding, a common command of every standard robot controller in the industry.

Earlier investigations show that the results of hazard identification (HAZID) and analysis (e.g. HAZOP or FMEA) can effectively be used for knowledge-based diagnosis of complex process systems in their steady-state operation. In order to extend this approach for transient operating conditions controlled by operating procedures, the notion of nominal input-output event sequences of qualitative signals has been introduced, and the deviations used in the procedure HAZID analysis have been defined therefrom. The diagnosis can then be performed algorithmically by matching the deviation sequences of the observed input-output event sequences and the nominal ones generated by qualitative dynamic models. The concepts and methods are illustrated using a simple case study consisting of a simple tank, controlled by an operating procedure. © 2011 Springer-Verlag.

The MIR research community requires coordinated strategies in dealing with databases for system development and experimentation. Manually annotated files can accelerate the development of accurate analysis tools for music information retrieval. This paper presents background information on an annotated database of vocal queries that is freely available on the Internet. First we outline the design and set up of the experiment through which the vocal queries were generated. Then attention is drawn to the manual annotation of the vocal queries. © 2003 Johns Hopkins University.

Hyperspectral imaging is a promising technique for identifying variety of seeds. But the hyperspectral features of seeds are vulnerable to the influence of years. Present modeling methods mostly depend on the training samples in the same year and prediction accuracy of these models will be decreased when these models are used to discriminate the same kind of seeds from the other different years. To improve the stability and robustness of the model, hyperspectral image coupled with model updating strategy based on support vector data description (SVDD) algorithm and Least squares support vector machine (LSSVM) was proposed. SVDD was used to find new samples which were not contained in the original model to update present SVDD model, respectively. Recognition experiments on four kinds of maize seeds under different years showed that the model updating strategy based on SVDD and LSSVM worked well, and the prediction accuracy of model was improved from 84.13% to 93.91% by adding 11.5% to 13.15% of samples under testing from other years to the original training set.

Intelligent manufacturing systems support a number of new functions, both for the real-time adaptive control of the machining process and for the supervision and control of the part and tool flow at the cell level. The paper presents a method and implementation solution for the intelligent control of machine tools tended by industrial robots, integrated in a CIM environment. An adaptive extension of the CNC processor provides on-line optimization of machine loading and batch productivity with tool monitoring by means of a machine vision subsystem, integrated in a local supervision computer. The local supervisor links hierarchical feature-based representation of parts and tools with the on-line built process-knowledge data base, generating intelligent commands for the NCAC and robot controllers.

The article discusses the theoretical foundations of the design of a single-channel ultrahigh frequency moisture meter with direct measurement of the moisture content of bulk materials. In accordance with the requirements of the methodology for selecting efficiency criteria, it is necessary to develop structural diagrams of measuring devices. For these purposes, the standard deviation of the random error is determined, characterizing the accuracy. It includes the main components: sensitivity error, zero error and additive component. Mathematical models of structures are constructed and the standard deviation of random errors, which are caused by certain parameters and additive fluctuations, is calculated. A single-parameter ultrahigh-frequency method for determining the moisture content is proposed. This method provides high accuracy of a single-channel ultrahigh frequency moisture meter with direct measurement of the moisture content of bulk materials. The measuring device can be used in the agricultural industry, where humidity is one of the important parameters, starting with harvesting and ending with the release of finished products. © 2024 IEEE.
