该协议通过使用开源软件斐济跟踪和分析手工竞技场中苍蝇的运动来评估 果蝇 的运动活动,该软件与插件兼容,以基于高清视频录制分割每帧的像素以计算速度、距离等参数。

该方法基于开源软件,从录制的视频中系统评估成虫和幼虫苍蝇的跟踪行为的局部运动活动。这种方法需要低成本的设备集成来记录和分析行为,使其成为筛选苍蝇运动的一种经济有效的方法。该技术用于识别具有局部运动障碍的人类疾病的苍蝇模型中的行为改变,但不适用于治疗疾病,残疾或困难。

在分析过程中必须清除相关的视频窗口,即原始视频窗口和处理视频窗口。首先,根据制造商的说明,以1比1的比例混合二氧化硅试剂盒的试剂A和试剂B,以准备用于果蝇运动跟踪的开放场地竞技场。接下来,将高清摄像机放在三脚架上,对其进行调整,使摄像机镜头垂直于二氧化硅竞技场的表面。
