PIXY2-CMUAM5

Addedto yourshopping cart

PIXY2 CMUCAM5更小,faster and more capable than the original Pixy.Like its predecessor,the Pixy2 can williamhill英格兰learn to detect objects that you teach it,just by pressing a button.此外,the Pixy2 has new algorithms that detect and track lines for use with line-following robots.有了这些新算法,您还可以检测交叉口和“道路标志”。The road signs can tell your robot what to do,such as turn left,向右拐,slow down,等。最好的部分是PixY2以每秒60帧的速度完成所有这些工作,so your robot can be fast,太!

无需使用微型电线-PixY2配有一条专用电缆,可直接插入Arduino,USB电缆可插入覆盆子PI,所以你可以很快开始。No Arduino or Raspberry Pi?No problem!PIXY2有几个接口,包括SPI,I2CUART和USB,通信简单,so you get your chosen controller talking to the Pixy2 in short order.

PIXY2使用基于颜色的过滤算法来检测对象。Color-based filtering methods are popular because they are fast,效率高,而且相对稳健。PIXY2从图像传感器计算每个RGB像素的色调和饱和度,并将其用作主要过滤参数。随着光线和曝光的变化,物体的色调基本上保持不变。光线和曝光的变化会对颜色过滤算法产生令人沮丧的影响,causing them to break.Pixy2's filtering algorithm is robust when it comes to lighting and exposure changes.

客户意见

  • Anyone know what 'J5' is about on the back of the board?I'm hoping to be able to remove the camera module and tether one off board.

  • 虽然最初的Pixy非常擅长物体检测,getting the coordinates out was a nightmare though!!!We tried using it to detect 2 retro-flective markers,尽管标记的检测工作异常出色,检索数据的I2c接口协议是如此复杂,我们最终放弃了,因为我们不能可靠地完成它。

    最大的问题似乎是从I2c中检索到的数据基本上是一个带有假定的同步标记的流。You would expect this to be a great system,但是,当试图在一个视频帧中处理多个对象时,该实现根本无法可靠地工作。It was also almost as though the coordinates were cleared out at the start of each video frame,所以经常你会读取块数据,它会返回一个零坐标和/或是完全不同步。

    我真的想要一个“捕获”命令,"status" command and a "retrieve coordinates" command.

    我将查看接口文档。Hopefully they have moved away from the stream format and/or made sure that once you start to retrieve a frame set nothing else is updated until you finished.

  • 这是一个庞大的国家名单,它不能运送到。有什么原因吗?

  • So in general,this is almost meant for use in the autonomous vehicle competition?:)

  • 我是最初的皮克斯的后援,他们说人脸检测很快就要开始了。As far as I know,从来没有发生过。Will the pixy2 威廉希尔公司在哪support face tracking?
