Ice hockey shot motion extraction from stereo videos

为给定的曲棍球运动员选择最好的曲棍球杆是一项重要的任务，目前通过使用昂贵且难以操作的动作捕捉设备获取曲棍球杆来实现这一任务。考虑到这项任务的复杂性和代价，这种类型的分析只适用于专业球员，而且只适用于专门设计的演播室。该项目的目标是使这一过程无处不在，并可供所有人使用。这个项目的目标是设计一个低成本的系统，只使用一个立体摄像机来捕捉曲棍球投篮中的球杆和冰球运动，并提取球杆运动、变形和冰球轨迹的抽象3D表示。该系统结构紧凑，便于移动，因此可以被带到曲棍球竞技场，也可以安装在零售店里，帮助主流曲棍球运动员、儿童和成年人选择最适合他们风格的曲棍球杆。我们通过为棍棒和冰球开发几种最先进的跟踪算法来实现这一点。在这一项目的第一阶段，在获得赠款期间，我们在实现这一目标方面取得了重大进展，展示了一个研究原型，并将其与MOCAP系统进行了比较。我们正在与CCM在这个项目上进行密切合作，CCM是一家领先的曲棍球设备制造公司，在蒙特利尔拥有大量业务。我们建议的系统将部署在至少25家商店，立即让足够多的人访问我们的系统。这有可能使棒子选择机制发生革命性的变化，从而使该公司以及整个加拿大博彩业受益。

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.
