In order to realize non-contact test of commodity over-package, a commodity over-package test system based on grating projection was designed. First obtain the three-dimensional point cloud of an object using one projector and two high-resolution cameras, then extract the bounding box of object point cloud to obtain algorithm, calculate the volume of bounding box and point cloud, and at last, test whether commodity package is over or not according to volume fraction and voidage. Experimental results showed that the system is capable of generating a bounding box effectively based on point cloud shape, and point cloud volume calculation accuracy reaches up to 95%, with time consumption reduced significantly in comparison with the widely used Poisson method.
