Abstract In view of the technical risks involved in the design, for development and manufacturing of visual equipment and smart equipment, factors such as long equipment development cycles were analyzed, and a truly reliable method for constructing a virtual simulation system of a virtual robot was proposed. Through the link based on OPC transmission protocol, the mechatronics MCD platform, the TIA platform, XSplit and Halcon were reorganized, and a virtual simulation system for visually guided robots was constructed for the first time in industrial production. In the real physical prototype e

Abstract:

In machine vision defects detection of pharmaceutical blister packaging, the traditional defects detection algorithms always do the binary image processing and edge feature extraction and other operations, and then locate the analysis image through these features. These operations are very tedious and inflexible. In this paper, the shape template matching algorithm is applied to pharmaceutical blister packaging defects detection. The algorithm can determine whether there is a positioning region of the sheet or pieces missing through search algorithm to locate the template image and comparing t

SummaryFour weeks of fieldwork in the forests of Mindoro, Philippines, in 1991 has elucidated the status of the six bird species endemic to the island. Of these, Ducula mindorensis and Otus mindorensis are high-altitude species with restricted ranges and in need of active conservation in the medium term. Three of the four lowland species, Gallicolumba platenae, Centropus steerü and Penelopides mindorensis are under immediate threat of extinction through forest clearance and fragmentation, while the fourth, Dicaeum retrocinctum, s i not under immediate threat but is certainly at risk of extinct

Abstract:

The technology is used to study and analyze the appearance defect characteristics of sprayed auto parts. The corresponding recognition method is developed by using MATLAB and Halcon software. Firstly, the causes of background noise and uneven brightness are described from the hardware and theory, and the specific treatment methods are given from the two perspectives of eliminating background noise and balancing illumination. A variety of frequency domain low-pass filters are constructed to eliminate background noise. The image preprocessing algorithm based on homomorphic filter is studied to a

Aiming at the problem of moving target recognition, a moving target tracking model based on FDRIG optical flow is proposed. First, the optical flow equation was analyzed from the theory of optical flow. Then, with the energy functional minimization, the FDRIG optical flow technique was proposed. Taking a road section of a university campus as an experimental section, 30 vehicle motion sequence images were considered as objects to form a vehicle motion sequence image with a complex background. The proposed FDRIG optical flow was used to calculate the vehicle motion optical flow field by the Hal

Abstract:

Chikungunya virus, a member of the Alphavirus genus, continues to present a global health challenge due to its widespread occurrence and the absence of specific antiviral therapies. Accurate detection of viral infections, such as chikungunya, is critical for antiviral research, yet traditional methods are time-consuming and prone to error. This study presents the development and validation of an automated image processing algorithm designed to improve the accuracy and speed of high-throughput screening for potential anti-chikungunya virus compounds.

Abstract:

Mechanical vibration in the high-temperature forging production line often causes large forging thermal dimensional measurement error in the detection task, so a vibration point cloud compensation method based on an acceleration sensor is proposed in this study. First, the vibration signal is obtained through the built-in acceleration sensor in the laser camera. After the acceleration of the camera vibration is detected, the displacement of the camera in three directions is solved by secondary integration. Subsequently, the coordinate value of the corresponding point is obtained by the rotatio
