+ | ====== RESULTS ====== | ||
+ | * Image Processing Algorithm used to process video/ | ||
+ | * Many different techniques used for point positioning of camera objects (described in the previous section) | ||
+ | * **Final Result:** Gradual build-up of points to obtain 3D point cloud | ||
+ | |||
+ | ===== POINT CLOUD ===== | ||
+ | The following 3D point cloud of a specific target area is visualized in terms of depth, using colour gradients, identifying objects that are nearer and further from the point of reference of the instrument.\\ | ||

+ | ====== FUTURE PROSPECTS ====== | ||
+ | The demand for high accuracy 3D model has rapidly increased in many fields such as engineering, | ||
+ | |||
+ | Point clouds can be directly rendered and inspected. They can also be transformed or converted to polygon mesh, triangle mesh, surface models or CAD models. These collectively can be described under the following umbrella terms: | ||
+ | |||
+ | * 3D Modeling | ||
+ | * 3D Scene Reconstruction | ||
+ | * Surface Reconstruction | ||
+ | |||
+ | Starting from the generated cloud, LAMP therefore offers the ability to **Measure, Map** and **Model** a given target object or area. | ||

+ | ====== NOVELTY AND FUTURE INNOVATION ====== | ||
+ | The following points summarize the novelty of a product as LAMP: | ||
\\ | \\ | ||
+ | * Uniquely designed 3D mapping system uses two lasers, one camera to produce 3D maps of arbitrary indoor environment. | ||
+ | * Separate Laser Range System. Uniquely designed by the team (T-Platform). | ||
+ | * Functions well with different types of camera quality. | ||
+ | * Customizable and can work with different visual or ranging sensors as well. | ||
+ | * Effective and affordable robotic platform. | ||
+ | * Sophisticated visual techniques. | ||
+ | * Produces comparable accuracy within its high effective range. | ||
+ | |||
+ | This product also has the potential to bring innovative changes in many different Geomatics fields. The possible future innovation is summarized below: | ||
+ | * Survey Industries - capture 3D positional data in areas of no GPS coverage. | ||
+ | * Construction Purposes- Mapping neighbourhood location and buildings that needs to be | ||
+ | * Transportation industry – Modeling smart transportation. | ||
+ | * Automobile industry – Mapping assembly line and modeling prototype. | ||
+ | * Defense and Public health safety. | ||
