# VEHICULAR EDGE COMPUTING SYSTEM

# PROBLEM:

As more and more research has been conducted on mobile edge computing, we propose that a mobile edge computing server in application can be deployed on-board a vehicle. But when performing tasks, the server will heat up very quickly and traditionally, the air-conditioner is needed. We try to avoid the use of air-conditioner, but put the server exposed to the air.

# SOLUTION OVERVIEW:

The vehicular mobile edge computing server is designed with a general server installed on-board vehicle. To make full use of the server, it will be accessed to the Internet and realize functionalities according to the existing theory of edge computing. To solve the problem of heating when performing intensive computational tasks, we utilize the wind to cool it down while designing waterproof to protect the server from rain.

# SOLUTION COMPONENTS:

## Modules on Waterproof and Shelter:

- The waterproof: To protect the server from rain or snow.

- The shelter: To carry the server with high stability.

- The airpath on the shelter: To utilize the wind to cool down the server effectively, even in relatively low car speed.

## Server Modules:

- The wireless communication access to the Internet.

- The server can perform relatively complex tasks like deep learning effectively.


# CRITERION FOR SUCCESS:

- Functionality: The mobile edge computing server can do computation tasks in the complexity level of deep learning, and access to the Internet to send or receive data. The waterproof and shelter should be stable and firm to fasten the server and protect it from rain. Also it can dissipate heat effectively.

- User experience: The user can get real-time access via the Internet and enjoy plentiful services like online video, etc.

- Durability and stability: The server needs to maintain a stable access to the Internet, and it can be used in rainy environment.

# 3D Scanner

# Problem

Our problem is how to design an algorithm that uses a mobile phone to take multiple angle photos and generate 3D models from multiple 2D images taken at various positions. At the same time, we will design a mechanical rotating device that allows the mobile phone to rotate 360 degrees and move up and down on the bracket.

# Solution Overview

Our solution for reconstructing a 3D topology of an object is to build a mechanical rotating device and develop an image processing algorithm. The mechanical rotating device contains a reliable holder that can steadily hold a phone of a regular size, and an electrical motor, which is fixed in the center of the whole system and can rotate the holder 360 degrees at a constant angular velocity.

# Solution Components

## Image processing algorithms

- This algorithm should be capable of performing feature detection which is essential for image processing. It should be able to accurately identify and extract relevant features of an object from multiple 2D images, including edges, corners, and key points.

- This algorithm should be designed to minimize the memory requirement and energy consumption, because mobile phones have limited memory and battery.

## Mechanical rotating system

Phone holder that can adjust its size and orientation to hold a phone steadily

Base of the holder with wheels that allows the holder to move smoothly on a surface

Electrical motor for rotating the holder at a constant angular velocity

Central platform to place the object

The remote-control device can be used to control the position of the central platform. Different types of motors and mechanisms can be used for up and down, such as the stepper motors, servo motors, DC motors, and AC motors.

# Criterion for Success

- Accuracy: The app should be able to produce a 3D model that is as accurate as possible to the real object, with minimal distortion, errors or noise.

- Speed: The app should be able to capture and process the 3D data quickly, without requiring too much time or processing power from the user's device.

- Output quality: The app should be able to produce high-quality 3D models that can be easily exported and used in other software applications or workflows.

- Compatibility: Any regular phone can be placed and fixed on the phone holder with a certain angle and does not come loose

- Flexibility: The holder with a phone must be able to rotate 360 degrees smoothly without violent tremble at a constant angular velocity
