This study focuses on the relationship between local compression and local bruise volume of kiwifruits by means of finite element method (FEM). The effects of four indenter shapes and three compression directions on the local kiwifruit bruise were considered. The local bruise volume and the irregular cross section area of kiwifruit were calculated. Multi‐scale kiwifruit 3D modelling based on irregular cross‐sectional area computed by slice‐integration method. Local compression bruise was simulated by FEM. The results of the local bruise test show that the contact force and the bruise volume of kiwifruit are positive linear correlation. Comparing the simulation with the experimental, the mean absolute percentage error (MAPE) of the reconstructed model is 0.0394, and the R2 of contact force–bruise volume curve is 0.8203. The maximum equivalent forces and abrasions occur in the 0° and 90° loading directions with the square indenter has been showed by FEM results.Practical applicationsSe‐enriched kiwifruit has high nutrition and economic value. Kiwifruits are often influenced by a variety of factors and processes from harvest to consumption time. Cleaning, transport, and various processing operations including peeling and slicing in the kiwifruit industry are responsible for local bruise to kiwifruit. Therefore, understanding the mechanism of local bruise caused by local contact force of kiwifruit plays an important role in reducing kiwifruit waste in the postharvest stage. Local bruise mechanisms can be used in harvesting and post‐harvest mechanical design and product transportation and positioning equipment.

“…The light projector will cast a series of high contrast light stripes patterns on the object and the processing part is to create a point cloud data based on the distortion of the light pattern casted on the object geometry captured by the camera [6] . Zhiping Xie performed a 3D image reconstruction of the Rosa Roxburghii fruit using structured light scanning method, where the point cloud processing algorithm developed achieved a volume error of 1.06% of the original fruit [7] .…”

The fruit industry has been known as one of the largest businesses in Malaysia, where most of the fruits pass through the peeling process well in advance before the final product as juice in a bottle or slices in a can. The current industrial fruit peeling techniques are passive and inefficient by cutting parts of the pulp of the fruit with peels leading to losses. To avoid this issue, a multi-axis CNC fruit peeler can be used to precisely peel the outer layer with the guidance of a 3D virtual model of fruit. In this work, a new cost-effective method of 3D image reconstruction was developed to convert 36 fruit images captured by a normal RGB camera to a 3D model by capturing a single image every 10 degrees of fruit rotation along a fixed axis. The point cloud data extracted with edge detection were passed to Blender 3D software for meshing in different approaches. The vertical link frame meshing method developed in this research proved a qualitative similarity between the output result and the scanned fruit in a processing time of less than 50 seconds.

Access to safe and secure food is an essential human requirement for a sustainable world. Ensuring the safety of fresh food products necessitates accurate analytical techniques. This study presents an innovative food safety approach using rapid 3D reconstruction and digital twin analysis in mixed reality. While 3D models offer comprehensive insights into fresh food, conventional reconstruction methods are often complex due to multiple cameras or sensors. To address this, the research employs monocular depth estimation for detailed 3D reconstruction from a single camera view. This architecture uses web service protocols and the Global-Local Path Networks (GLPN) model for monocular depth perception, effectively translating 2D images into intricate 3D structures. These digital twins establish a strong foundation for enhanced analysis of food products, facilitating a better understanding of safety risks. The study also explores the applicability of transferring 3D models to Microsoft HoloLens 2, enabling immersive visualization and novel avenues for analysis. These techniques hold significance for the food industry, spanning scene comprehension, precision agriculture, robotics, augmented reality, and medical imaging. The methodology includes assessing surface degradation, with a focus on bruises on fresh produce. Employing a mesh overlay technique on the resulting 3D models distinctly showcases the impact of bruising. Sequential data recordings effectively track bruise expansion, shedding light on structural compromises. This technique dynamically portrays bruise progression, thus enriching comprehension of its implications on produce quality.
