規格參數

  • 輸入電壓:5V
  • 像素:30萬
  • 分辨率:640*480, 320*240, 160*120
  • 串口波特率:9600~115200
  • 圖片JPEG壓縮,高、中、低三檔可選

  • 焦距可調

應用示例

這個demo會向展示如何利用Seeeduino及SD Card Shield,把攝像頭採集到的數據存到SD卡中,為了方便使用,加了一個Button,每按一下進行一次拍攝並保存。跟著下面的步驟,你可以快速的讓你的Grove – Serial Camera Kit跑起來!

硬件連接

SD Card Shield V4.0上有一個I2C和一個UART的Grove口,所以這裡不需要Base Shield。把Button接到SD Card Shield 上的I2C接口,攝像頭插到Uart接口。

下載程序及燒錄代碼

你可以上github下載示例代碼,點這裡
下載完後,把程序燒錄到Arduino/Seeeduino,就可以開始工作了。

拍一張照片

下載完程序之後,只需要按一下按鍵,就可以拍一張照片,照片會存放到SD卡里面。下面的照片是用平角鏡頭拍的我辦公室的天花板。

更換一個鏡頭

套件配有一個廣角鏡頭,下面會教你如何更換鏡頭。

首先你需要有一個十字小螺絲刀:

GSCK Step1.jpg

擰開鏡頭側面的螺絲:

嘗試旋動鏡頭,逆時針可以把它擰出來:

然後我們換上廣角鏡頭,同樣的拍了一張我辦公室天花板的照片!
看看跟上面用平角鏡頭拍的有什麼不同?

怎麼調焦

在安裝鏡頭的時候,旋入不同的深度表示不同的焦距,你可以嘗試一下並且發現它的規律。

Grove – Serial Camera Kit includes one control board and two interchangeble lenses, one is standard lens and the other is wide-angle lens. It’s a great camera for Arduino centered image recognition projects, because 30W pixel wouldn’t be overwhelming for Arduino, so that real-time image recognition is possible. To make it more fun and playable, lenses of two specs are shipped in this kit. The standard one is for common photo shots and the wide-angle one is specially suitable for monitoring projects.
Specifications
  • Input Voltage: 5V
  • Pixel: 300,000
  • Resolution: 640*480, 320*240, 160*120
  • Uart Baud Rate: 9600~115200
  • Communication: RS485 and RS232
  • Photo JPEG compression, high, medium and low grades Optional
  • AGC
  • Auto Exposure Event Control
  • Automatic White Balance Control
  • Focus adjustable

Demonstration

This demo will show you how to use Grove – Serial Camera Kit. We need a Seeeduino, an SD Card Shield and a Grove – Button. When the button pressed, we take a photo and save it to SD Card. Follow the below steps step by step, you can easily run your Grove – Serial Camera Kit. Then let’s go.

Hardware Installation

We can find that there are two Grove interfaces on SD Card Shield V4.0, so we needn’t a Base Shield, just plug Button to I2C Grove and plug Camera to Uart Grove.

Download Code and Upload

You can download demo code in github, click here

Then upload the code, and it works.

Take a Photo

After finish uploading demo code, we can take a photo now, just press the button, then wait for a few seconds, a photo will be saved to SD card.
The following image is the ceiling of my office use straight angle lens.

Replacing a Lens

There is another wide-angle lens, I will show you how to replace it.

Firstly you should have a screwdriver:

GSCK Step1.jpg

Then, unscrew the screws on the side of lens:

GSCK Step2.jpg

Try rotating the lens, it can be screwed out:

GSCK Step3.jpg

We use the wide-angle lens to take a photo, also, it’s the ceiling of my office!
Find anything different from the ceiling image previous?

How To Focus

Lens screwed different depths represent different focal length, you can have a try.
