Three-dimensional (3D) point cloud analysis has become one of the attractive
subjects in realistic imaging and machine visions due to its simplicity,
flexibility and powerful capacity of visualization. Actually, the
representation of scenes and buildings using 3D shapes and formats leveraged
many applications among which automatic driving, scenes and objects
reconstruction, etc. Nevertheless, working with this emerging type of data has
been a challenging task for objects representation, scenes recognition,
segmentation, and reconstruction. In this regard, a significant effort has
recently been devoted to developing novel strategies, using different
techniques such as deep learning models. To that end, we present in this paper
a comprehensive review of existing tasks on 3D point cloud: a well-defined
taxonomy of existing techniques is performed based on the nature of the adopted
algorithms, application scenarios, and main objectives. Various tasks performed
on 3D point could data are investigated, including objects and scenes
detection, recognition, segmentation and reconstruction. In addition, we
introduce a list of used datasets, we discuss respective evaluation metrics and
we compare the performance of existing solutions to better inform the
state-of-the-art and identify their limitations and strengths. Lastly, we
elaborate on current challenges facing the subject of technology and future
trends attracting considerable interest, which could be a starting point for
upcoming research studies
