描述

Pixy CMUcam5 高清攝像頭圖像識別感測器模組 美國 SparkFun 原裝進口

Pixy CMUcam5是一款速度非常快的圖像傳感器,可以教授如何查找各種形狀,尺寸和顏色的物體。Pixy能夠同時跟踪數百個物體,可以用於機器人,家庭自動化,顏色編碼等等,而只是為您提供您實際需要的信息。Pixy確實是一個快速且易於使用的視覺系統,配備專用恩智浦LPC4330處理器,使其能夠處理來自其圖像傳感器的大量數據,并快速處理,同時輸出每秒50次的檢測結果。

Pixy處理來自圖像傳感器的圖像,僅將有用的信息發送到微控制器,以每秒50幀的速度進行。這意味著每個Pixy CMUcam5每1/50秒(20毫秒)處理一個完整的640×400圖像幀。該信息可通過以下幾種接口之一獲得:UART串行,SPI,I 2 C,USB或數字/模擬輸出。因此,您的Arduino,Raspberry Pi,BeagleBone或其他微控制器可以輕鬆與Pixy交談,並且仍然有足夠的CPU可用於您需要他們執行的其他任務。

Pixy使用基於顏色的過濾算法來檢測對象。基於顏色的過濾方法是流行的,因為它們快速,高效且相對健壯。Pixy從圖像傳感器計算每個RGB像素的色相和飽和度,並將其用作主要濾波參數。物體的色調在照明和曝光的變化上基本保持不變。照明和曝光的變化會對濾色算法產生令人沮喪的影響,從而導致它們被破壞。Pixy的濾波算法在照明和曝光變化方面非常強大。

原廠技術文件與範例

The Pixy CMUcam5 is a remarkably fast image sensor that is able to be taught to find objects of various shapes, sizes, and colors. With the capability of tracking hundreds of objects simultaneously, the Pixy can be used in robotics, home automation, color coding, and more all the while only providing you with the information that you actually want. Pixy really is a fast and easy-to-use vision system equipped with a dedicated NXP LPC4330 processor making it capable of handling large loads of data from its image sensor and processing it quickly while outputting what it detects 50 times per second. Pixy processes images from the image sensor and only sends the useful information to your microcontroller, doing so at 50 frames per second. This means each Pixy CMUcam5 processes an entire 640×400 image frame every 1/50th of a second (20 milliseconds). The information is available through one of several interfaces: UART serial, SPI, I2C, USB, or digital/analog output. So your Arduino, Raspberry Pi, BeagleBone, or other microcontroller can easily talk with Pixy and still have plenty of CPU available for other tasks you need them to do. Pixy uses a color-based filtering algorithm to detect objects. Color-based filtering methods are popular because they are fast, efficient, and relatively robust. Pixy calculates hue and saturation of each RGB pixel from the image sensor and uses these as the primary filtering parameters. The hue of an object remains largely unchanged with changes in lighting and exposure. Changes in lighting and exposure can have a frustrating effect on color filtering algorithms, causing them to break. Pixy’s filtering algorithm is robust when it comes to lighting and exposure changes.
