Introduction

Project Definition

A free throw is a deciding factor in basketball. It can bring you the championship trophy or can send you home early. If your team is surrounded with good shooters, then you might not worry about missing free throws that can cost you the game, but if you have some bad free throw shooters, that can end up changing your whole strategy for the game. With our system, we are aiming to make the players more successful at the free throw line which will prevent the teams from changing their offensive strategies.

Project Plan

Work Breakdown Schedule

WBS will show our project plan with way things are going to work in. With this you can see the evaluation and the phases of work. Every phases will be detailed in our gantt chart. We will show the importance of the levels on other phases

Project Proposal

With our project, we are aiming to improve the free throw percentage of any player depending on some basic factors.

Field Research

As far as we know there are no programming project about that but there are some studies about probable best shot formula.

Proposal

Enhancing %20 of success of any player who had below %50 is our main proposal.

Project Plan

Preparing the Project Plan

We prepared this project plan document to be able to move forward easily and planned.

Analysis

Assumptions

-High definition free throw footage is required. (min 720p)

-The footage should have no other basketballs or players.

-The following footage angles are necessary:

-Left (Example Footage)

-Right

-Back

-Left and Right Shooter Close-up

Determining Requirements

After doing some research, we came up with these factors:

1) Before the shot, determine the following distances and angles from the video stream:

-Left Foot Position(Distance, Angle)

-Right Foot Position(Distance, Angle)

-Shooter(Length, Standing Reach)

-ShootingArmAngle(Ground,UpDown)

Ground is angle number 2

UpDown is angle number 1

-TheAngleBetweenFootAndLowerLeg

Angle number 4

-TheAngleBetweenLowerAndUpperLeg

Angle number 3

2) On release:

-Ball Position(Distance to Hoop, Release Velocity)

-Left Foot Position(Distance, Angle, HeelStatus)

-Right Foot Position(Distance, Angle, HeelStatus)

-ShootingArmAngle(Ground,UpDown)

Ground is angle number 2

UpDown is angle numer 1

-NumberOfShootingFingers

-TheAngleBetweenFootAndLowerLeg

Angle number 4

-TheAngleBetweenLowerAndUpperLeg

Angle number 3

Design and Programming

UI Design

For the UI, we are thinking about a simple screen which requests video streams, and returns the suggested factors for the player on the video.

Image Processing Implementation (Collecting Data)

To collect data, we selected to use OpenCV library. We are currently exploring different algorithms that can do what we are expecting.

Best Shot Formula Implementation

Still researching the impacts of the factors...

Estimates

We are aiming to finish the project by May, 2016. Detailed estimations on tasks can be found below:

   Project Proposal (September – End of September)

   Project Plan (End of September – End of October) 

   Analysis (Mid of October – Beginning of December)

   Design and Programming (Beginning of December – End of March)

   Testing (Beginning of February – End of May)

Resources

Software Development Process

We decided to develop our program with using Waterfall Method as a sequential design process because it is easy to understand. Also to proceed next part, each part must be completed fully. At the end of each section we have to determine if the project is on the right way.

Schedule

Logs

Week 1&2

We try to decide what we can do as a senior project. Since we are basketball fan we decided to work on one of the major basketball problem which is improvement of free throw percentage. To do that we outlined the basics of project then we decided that we could handle this via OpenCV with video processing. After we specified waterfall method as a sequential design process. We needed to some data for specifying factors.

Week 3&4

We went to gym to record some free throw shot. We needed some restrictions to record a clip and these were a camera with at least 720p video quality, no other basketball or player on the background (just one shooter and one ball), stable and tree different angle which are left, right and back. After some records we noticed what factor we should take care of for the calculating best free throw shot. For example distance between player and hoop, shooting elbow angle, .etc.

Week 5&6

We know that OpenCv is a powerful library and we read some manuals and did some research for video processing. –To be continued…

Gantt Chart will be uploaded...
