The presently disclosed embodiments relate to the field of imaging and scanning technologies. More specifically, embodiments of the present disclosure relate to systems and methods for providing a visual feedback to a user showing rendering and 3D scanning of an object in real-time so that the user can monitor or review a quality of the scanning/rendering in the real-time.
A three-dimensional (3D) scanner may be a device capable of analysing environment or a real-world object for collecting data about its shape and appearance, for example, colour, height, length width, and so forth. The collected data may be used to construct digital three-dimensional models. Usually, 3D laser scanners create “point clouds” of data from a surface of an object. Further, in the 3D laser scanning, physical object's exact size and shape is captured and stored as a digital 3-dimensional representation. The digital 3-dimensional representation may be used for further computation. The 3D laser scanners work by measuring a horizontal angle by sending a laser beam all over the field of view. Whenever the laser beam hits a reflective surface, it is reflected back into the direction of the 3D laser scanner.
In the present 3D scanners or systems, there exist multiple limitations. For example, a higher number of pictures need to be taken by a user for making a 360-degree view. Also the 3D scanners take more time for taking or capturing pictures. Further, a stitching time is more for combining the more number of pictures (or images). Similarly, the processing time for processing the more number of pictures increases. Further, because of more number of pictures, the final scanned picture becomes heavier in size and may require more storage space. In addition, the user may have to take shots manually that may increase the user's effort for scanning of the objects and environment. Further, the present 3D scanner does not provide real-time merging of point clouds and image shots. Also a final product is presented to the user, there is no way to show intermediate process of rendering to the user. Further, in existing systems, some processor in a lab does the rendering of the object.
In light of above discussion, there exists need for better techniques for three-dimensional (3D) scanning and rendering of objects in real-time. The present disclosure provides 3D scanning systems and methods for 3D scanning of objects by providing visual feedbacks about scanning and rendering of object in real-time to a user. The user can check and make changes, if required, for enhancing a scanned image.

It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, may be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the acts specified in the flowchart and/or block diagram block or blocks. These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to operate in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the acts specified in the flowchart and/or block diagram block or blocks. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operations to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the acts specified in the flowchart and/or block diagram block or blocks.
In addition, methods and functions described herein are not limited to any particular sequence, and the acts or blocks relating thereto can be performed in other sequences that are appropriate. For example, described acts or blocks may be performed in an order other than that specifically disclosed, or multiple acts or blocks may be combined in a single act or block.
While the invention has been described in connection with what is presently considered to be the most practical and various embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements.
