Ice hockey shot motion extraction from stereo videos

为一个给定的冰球运动员选择最好的冰球棒是一项重要的任务，目前通过使用昂贵且难以操作的动作捕捉设备来获得冰球的运动。考虑到任务的复杂性和价格，这种类型的分析只适用于专业玩家，并且只适用于专门设计的工作室。这个项目的目标是使这个过程无处不在，并可供所有人使用。该项目的目标是设计一个低成本的系统，该系统仅使用立体摄像机设置来捕捉冰球射击中的球杆和冰球运动，并提取出球杆运动、变形和冰球轨迹的抽象3D表示。该系统紧凑，可移动，因此可以带到冰球场或可以设置在零售商店，在那里将帮助主流曲棍球运动员，儿童和成人都选择最好的曲棍球棒为他们的风格。我们通过为棍球和冰球开发几种最先进的跟踪算法来实现这一目标。在这个项目的第一阶段，在参与资助期间进行，我们已经朝着目标取得了重大进展，并展示了一个研究原型，并将其与MOCAP系统进行了比较。我们在这个项目上与CCM密切合作，CCM是一家在曲棍球装备制造方面领先的公司，在蒙特利尔拥有大量业务。我们提出的系统将在至少25家商店中部署，立即为我们系统的关键人群提供访问权限。这有可能彻底改变摇杆选择机制，从而使公司和整个加拿大游戏行业受益。

Selecting the best hockey stick for a given hockey player is an important task that is currently achieved by acquiring the stick an puck motion using expensive and difficult to operate motion capture equipment. Given the complexity and price of the task, this type of analysis is only available to professional players and only in specially designed studios. The goal of this project is to make this process ubiquitous and available to all. The goal of this project is to design a low cost system that only uses a stereo camera setup for capturing the stick and puck motion in a hockey shot, and to extract an abstracted 3D representation of the stick movement, deformation, and puck trajectory. This system is compact and mobile and therefore can be brought to hockey arenas or can be setup in retail shops where will help mainstream hockey players children and adults alike select the best hockey stick for their style. We achieve this by developing several state of the art tracking algorithms for both stick and puck. In the first phase of this project, carried out during the Engage grant, we have made significant progress towards the goal and demonstrated a research prototype and compared it agains the MOCAP system. We are collaborating closely on this project with CCM, a leading company in hockey equipment manufacturing that has a large presence in Montreal. Our proposed system will be deployed in at least 25 stores instantly giving access to a critical mass of people to our system. This has the potential of revolutionizing the stick selection mechanism, thus benefiting the company as well as the Canadian gaming industry as a whole.
