Camera VC0706，延时摄影
本帖最后由 code-AR 于 2015-3-22 22:48 编辑很长段时间没有混在论坛了，平时就是签个到。今天带了个新玩意吧，利用VC0706串口摄像头定时拍摄照片，以制作延时摄影
不知道什么是延时摄影的，自行度娘去。整个流程就是用arduino来控制摄像头拍摄照片，并存储到SD卡中，最后用SD卡中的照片来制作延时摄影的影片，利用了arduino UNO，外加SD卡模块，VC0706串口摄像头(可以在加个蓝牙模块，监控拍摄信息）。来个简陋的硬件图吧，
→_→
这些组合起来，再外加个5000mAH的移动电源。用个纸盒包装起来，即可成个延时摄影器材，电力可以支持十几个小时的拍摄工作。再来就是硬件的连接图（其中的蓝牙模块，可要，可不要。我主要是拿来检测拍摄信息的）

代码部分（基于vc0706的库文件的例程修改）
//自动延时摄影
//MCU内部自走时，设定时间，驱动VC0706进行拍照
//库文件定义声明
#include <Adafruit_VC0706.h>
#include <SPI.h>
#include <SD.h>
#include <SoftwareSerial.h>
// sd卡CS/SS端接pin 10
#define chipSelect 10
#define DelayTime 30000//定义延时时间
static long timer;
// 对于 Uno: camera TX 接 pin 2, camera RX 接 pin 3:
SoftwareSerial cameraconnection = SoftwareSerial(2, 3);
Adafruit_VC0706 cam = Adafruit_VC0706(&cameraconnection);
void setup() {
pinMode(10, OUTPUT); // SS on Uno, etc.
Serial.begin(9600);
Serial.println("VC0706 Camera test");
// see if the card is present and can be initialized:
if (!SD.begin(chipSelect)) {
Serial.println("Card failed, or not present");
// don't do anything more:
return;
}
// Try to locate the camera
if (cam.begin()) {
Serial.println("Camera Found:");
} else {
Serial.println("No camera found?");
return;
}
// Print out the camera version information (optional)
char *reply = cam.getVersion();
if (reply == 0) {
Serial.print("Failed to get version");
} else {
Serial.println("-----------------");
Serial.print(reply);
Serial.println("-----------------");
}
// 设置照片尺寸 -640x480, 320x240 or 160x120
//cam.setImageSize(VC0706_640x480); // biggest

// You can read the size back from the camera (optional, but maybe useful?)
uint8_t imgsize = cam.getImageSize();
Serial.print("Image size: ");
if (imgsize == VC0706_640x480) Serial.println("640x480");
if (imgsize == VC0706_320x240) Serial.println("320x240");
if (imgsize == VC0706_160x120) Serial.println("160x120");
timer = 0;
}
void loop() {
if (millis() > timer + DelayTime) {
timer = millis();
Serial.println("Delay Done!");
if (! cam.takePicture())
Serial.println("Failed to snap!");
else
Serial.println("Picture taken!");
char filename;
strcpy(filename, "IMAGE000.JPG");
//设定是最大1000张，即IMAGE000至999
for (int i = 0; i < 1000; i++) {
filename = '0' + i/100;
filename = '0' + (i%100)/10;
filename = '0' + (i%100)%10;
// create if does not exist, do not open existing, write, sync after write
if (! SD.exists(filename)) {
break;
}
}
File imgFile = SD.open(filename, FILE_WRITE);
uint16_t jpglen = cam.frameLength();
Serial.print(jpglen, DEC);
Serial.println(" byte image");
Serial.print("Writing image to "); Serial.print(filename);
while (jpglen > 0) {
// read 32 bytes at a time;
uint8_t *buffer;
uint8_t bytesToRead = min(32, jpglen); // change 32 to 64 for a speedup but may not work with all setups!
buffer = cam.readPicture(bytesToRead);
imgFile.write(buffer, bytesToRead);
//Serial.print("Read ");Serial.print(bytesToRead, DEC); Serial.println(" bytes");
jpglen -= bytesToRead;
}
imgFile.close();
Serial.println("...Done!");
cam.resumeVideo();
}
}
自己制作的视频（渣画质，慎点），外加vc0706库文件。。。

希望有兴趣的朋友，可以分享自己拍摄的作品那，也可以在这个基础上完成其他好作品，谢谢！！！
你好，按你说的，我出现这个情况
串口显示0 byte image，我在SD卡中也看到了图片。但都是0B，打开错误，怎么解决？ 支持一个！厉害啊！ mark! VC0706串口摄像头这个模块没用过，有机会玩下 谢谢分享学习一下 楼主，你的文件里怎么还有Py文件？求教 suoma 发表于 2015-3-25 08:58 static/image/common/back.gif

这个还有树莓派支持， code-AR 发表于 2015-3-25 10:12 static/image/common/back.gif
这个还有树莓派支持，
用树莓派的话，该怎么接线？ 那两个电阻是什么作用？不加可以吗？ 那个红色的RN是什么模块？ 如果用蓝牙模块，程序是什么样？如何与手机建立连接？ suoma 发表于 2015-3-31 18:35 static/image/common/back.gif

先看看接线问题，再发个代码看看吧。 code-AR 发表于 2015-4-4 16:35 static/image/common/back.gif

你检查了接线没有，有可能是接线问题。没识别到相机， VC0706接线一样，我用的是W5100上的SD模块，直接堆叠到arduino上
