“…From this assumption, there are many techniques developed by researchers that are related by mathematical models and numerical analysis. There are many published [18][19][20][21][22][23][24], using only top view image which acquired from single 2D computer vision to extracted maximum width and height of object to estimate whole volume from mathematic model. Some researchers used disk methods to improve the accuracy, by slicing the material as virtual slices.…”

The volume measurement using machine vision system is contactless techniques that play an important role in industries now a day. Basically, three-dimensional reconstruction is required to determine a depth using a special lighting system or multiple cameras. This increases the complexity of the measurement system. A fast and simple machine vision framework called RayVol for estimating the volume of axisymmetric objects in near real-time using a single camera and simple illumination is presented. The RayVol framework employs a shadow casting method to reconstruct the 3D shape of the object by tracing rays from the object’s shadow pixels to the light source location. The result of this technique shows a significant accuracy improvement from the area-projection method. A virtual slice representing the cross-section of an object is reconstructed using a cubic spline approximation from baseline points derived from the boundary pixels of the object image and a shadow casting method. The volume estimation was calculated by restricted integration using the Riemann sum estimation algorithm, and the closed area of the virtual slices was calculated using the shoestring algorithm. Mangoes were used as a case study of the RayVol framework. The volume estimation provides the correlation coefficient of 0.9849 between the developed system and the water replacement method.

“…We present an approach for volume estimation from a single top-view 2D image of the fruit with its shadow. In this research, we used the mango as the test material, which is considered an irregular or axisymmetric shape [3,23,24].…”
