With the advent of new generation d

With the advent of new generation depth sensors, the use of three-dimensional (3-D) data is becoming increasingly popular [19]. 3D object recognition can be defined as the problem of finding all instances of the database models in an arbitrary scene with determining the pose of the detected objects. The pose of the object is the rigid transformation that aligns the object in the database to the object's instance in the scene [1]. In 2D, the rigid transformation has three components. They are two translations in each of the x and y directions and a rotation in the xy-plane. In 3D, the pose has six components which are the translations in each of the of x, y, and z directions as well as a rotation about each of these three axes. Therefore, solving the problem of 3D object recognition is the problem of finding a known object in the scene along with its 6D pose [1]. 3D data can be captured from a multitude of methods including 2D images and acquired sensor data. Acquisition from 2D images, 3D data acquisition and object reconstruction can be performed using stereo image pairs. Stereo photogrammetry or photogrammetry based on a block of overlapped images is the primary approach for 3D mapping and object reconstruction using 2D images. Acquisition from acquired sensor data, Can using a variety of sensors, including [1, 20]: stereo cameras, time of fight laser scanners such as LiDARs, as well as infrared sensors such as the Microsoft Kinect or Panasonic DI-Imager. All of these sensors can only capture a single view of the object with a single scan. This view is referred to as a 2½D scan of the object. Therefore, to capture the entire 3D shape of the object, the sensor captures multiple instances of the object from different viewpoints
