This paper describes the integration of publicly available geoinformation into a simulation environment. Within the research project `AutoBin', the autonomous control of an inland vessel is to be tested in a simulated environment and the developed algorithms are to be validated. This requires a photorealistic simulation within a modern game engine. In this paper, the different sources of the used geodata are presented. Furthermore, the necessary adaptations of the data for the desired integration into the simulation are shown. At the end of the integration of the different data sources, an environment model of the entire test field in the project `AutoBin` - a part of the Dortmund-Ems-Canal from the lock Waltrop to the port of Dortmund - is created. The last section of this paper describes the necessary adaptations to integrate the environment model into the simulation infrastructure of the research and control center for autonomous inland vessels `VeLABi'.

Imaging confocal microscopy (ICM) and focus variation (FV) are two of the most used technologies for 3D surface metrology. Both methods rely on the depth of focus of the microscope objective, which depends on its numerical aperture and wavelength of the light source to compute an optical section. In this paper we study how several methods of structured illumination microscopy affect the metrological characteristics of an areal optical profiler. We study the effect of the projection of different structured patterns, the sectioning algorithms, and the use of high and low frequency components onto the optically sectioned image. We characterized their performance in terms of system noise, instrument transfer function and metrological characteristics such as roughness parameters and step height values.

Jointly computing the square root (SQRT) and the inverse square root (ISQRT) of floating-point numbers is common in many algorithms, e.g., in image or time series data processing when computing norms or vector normalization. Existing designs suffer from high latency and inefficient resource utilization due to the separate architectures that carry out these two operations. In this paper, we first propose a non-iterative approximation method for computing SQRT and ISQRT based on the Chebyshev min-max criterion to reduce the latency while meeting the accuracy requirements of various applications;thereafter a shared architecture of these two operations is designed and implemented in FPGA with less logic units. In contrast with other approximation solutions, our method does not need to perform any iterations and the accuracy can be mathematically estimated. A comparison with vendor-provided IP cores for FPGAs revealed that our proposed SQRT/ISQRT floating-point IP core utilizes less resources while reducing the clock-cycle latency by nearly four times.

This paper introduces an intelligent delta robot system enhanced with imageprocessing to optimize Pick & Place operations in Agricultural Produce Centers (APCs). Facing a critical demand for mechanization in agriculture due to a shrinking rural workforce, our system utilizes camera-based segmentation and depth estimation to efficiently automate the packaging of fruits and vegetables. It concentrates on essential tasks such as precise gripping and ungripping, supported by advanced camera-based visual sensors. Integrating these vision technologies with delta robot kinematics and specialized imageprocessingalgorithms allows the robot to execute highly accurate movements. Our implementation showcases significant enhancements in the efficiency and reliability of APC operations, advancing the field of agricultural robotic automation and establishing a new standard for future developments in automated food production.

With the increase of image data scale, a faster and more efficient image acquisition and processing system is needed. FPGA has good parallel performance, which is very suitable for algorithms dealing with basic parallel features, and can greatly improve the efficiency of image acquisition and processing system. Aiming at the problem of FPGA image acquisition, processing and display, this paper carries out the design of real-time image acquisition system, which has the function of real-time display after processing the acquired image. In this paper, the chip of EP4CE6F17C8 of Cyclone IV series is used, the CMOS camera is OV5640 and the monitor is VAG. After full experimental verification, the system is extensible, the later expansion goal can not be achieved without the cooperation of Bluetooth and other facilities, with the role of recognizing and positioning license plates, obviously this series of application prospects are considerable; With flexibility, can customize the algorithm for optimization; Low cost a series of advantages.
