Blocks Tab Pixy can detect/track literally hundreds of objects at the same time. Each detected object is reported as a “block,” with a specific signature number, location within the image, and size (width and height). The blocks are reported through one of its serial ports (UART, SPI, I2C, USB, analog and digital output) for each frame (every 20 milliseconds) . This tab contains some parameters for controlling the number of blocks Pixy will report for each frame. To bring up the Block Tab, firs…

Can I replace the lens on Pixy? You can! Pixy ships with a 75-degree field of view lens (2.8mm focal length, F2.0 aperture), which is great for robotics applications, but your application may need something different, perhaps something that can see distant objects better (longer focal length) or see more objects (wider field of view and shorter focal length). Or a lens without an IR-cut filter, so that Pixy can sense infrared.

PixyMon is crashing! This has only been reported by Mac users. We think there is an OSX version problem/incompatibility with the binaries we're building. We avoid this problem in Linux by not distributing PixyMon in binary form. If PixyMon is crashing, we'd like you to send us a note (

PixyMon Overview PixyMon is an application that allows you to configure Pixy and see what it sees. It runs on several different platforms including Windows, MacOS and Linux, as well as other smaller embedded systems like Raspberry Pi and BeagleBone Black.

Running the Pan/tilt Demo OK, you've assembled the pan/tilt mechanism and it looks cool, but it would look even cooler if it moved. One nice thing is that you don't need a battery to move the pan/tilt -- the pan/tilt can use the USB cable for power, as long as the cable is 4 ft or shorter

Signature Labels Tab The Signature Labels Tab allows you to label objects that are detected by Pixy. This feature only works within PixyMon when in Default and Cooked modes. Note also that the signature labels are stored on Pixy. So if you set some signature labels and then plug your Pixy into another computer running PixyMon, the labels will be there.

Some Tips on Improving Detection Accuracy Pixy's color filtering algorithm can process an entire frame in 20 ms (50 times a second). But discrimination can sometimes be a problem -- false positives and false negatives. False positives are when Pixy thinks an object matches a particular signature, but it's not the object you want to detect. It's often an object with a similar hue. For example, Pixy thinks your light green shirt matches a green ball. False negatives are when Pixy fails to detect …

Teach Pixy an Object Teaching Pixy an object is super easy, but first let's talk about which objects will work well with Pixy. Pixy uses a hue-based color filtering algorithm to detect objects. Since Pixy uses hue (color), the object needs to have a distinct hue. Here are some objects that are good because they have good, distinct hues.

Uploading New Firmware Pixy uses a ROM-based algorithm to upload new firmware into flash memory over USB, which makes Pixy “unbrickable” - that is, you will always be able to recover Pixy from an unsuccessful firmware upload or a “bad” version of firmware.

wiki:v1:using_color_codes

Anonymous (anonymous@undisclosed.example.com) — 2018-02-05T23:47:55+0000

Using Color Codes Introduction So, what’s a “color code”? A color code (CC) is two or more color tags placed close together. Pixy can detect and decode CCs and present them as detected objects (firmware versions 1.0.0 and higher). For example, using 2-tag CCs (like the photo above) and limiting yourself to a palette of 4 colors (i.e. teaching Pixy 4 different color signatures), you can generate up to 12 unique objects. That's just the tip of the iceberg - 3, 4, and 5-tag CCs with more / dif…

What about Raspberry Pi support? It appears that Qt is ported for Raspberry Pi. We haven't played with it, but we assume it works well enough to run PixyMon (which isn't a complex Qt program). Libusb certainly works on Raspberry Pi -- so our guess is it would be an easy recompile. Maybe someone could shed more light on this, but we're thinking it'll be easy to get working, especially once Linux support is released.

Anonymous (anonymous@undisclosed.example.com) — 2018-10-24T21:40:34+0000

What is the maximum distance that Pixy can detect objects? Pixy can detect an object that is miles away as long as the object is large enough. Described another way -- Pixy will detect an object that's as small as 4×1 pixels in the image. This means it can detect a ping-pong ball sized object at 10 feet (a 40mm object at 3 meters), assuming a 75 degree field-of-view lens (the lens Pixy ships with). A lens with a longer focal length can greatly extend the detection distance, but with a narrower …

Will Pixy track/sense IR light? Pixy ships with a lens with an IR-cut filter because infrared light interferes with the color response, but Pixy's image sensor is quite responsive to infrared light. Replacing the IR-cut lens is quite easy, so the answer is yes, Pixy can track and sense IR light.
