Yunkey Technology sales engineers found that many customers need to support multiple image sensors at the same time.Each image sensor needs to take pictures in full synchronously, using the same parameters.So we develop a variety of multi-eye cameras. Each camera can set whether a sensor above works, and then synthesize the working sensor image into one image and output it to the computer.
The following is our one-stop four products.
Some code
nowrap;">Write a simple code to introduce how this camera gets pictures and displays them using opencv.Use the code in "CKSDK 6 Steps to Obtain Cloud Key Industrial Camera Image" to slightly modify it.
#include <stdio.h>
#include <string>
#include <opencv2/opencv.hpp>
#include"CKCameraInterface.h"
void process_multi_sensors_ckcamera()
{
HANDLE hCamera;
intcameraNum;
//Step 1: Find all cameras
int ret = CameraEnumerateDevice(&cameraNum);
if (ret < 0 || cameraNum == 0)
return;
if (ret < 0 || cameraNum == 0)
return;
if (ret < 0 || cameraNum == 0)
return;
//Step 2: Turn on the first camera
ret = CameraInit(&hCamera, 0);
if (ret != CAMERA_STATUS_SUCCESS)
return;
ret;
ret;//Set the format of image output, this step is not necessary
//Set which sensors do work, bit0 represents sensor0, bit1 represents sensor1, bit2 represents sensor2, bit3 represents sensor3
//CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0x1); //Only output sensor0
//CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0x2); //Only output sensor1
//CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0x4); //Only output sensor2
//CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0x4); //Only output sensor2
//CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0x8); //OnOnly output sensor3
CameraSetIntValue(hCamera, IMAGE_CHANNEL_MASK, 0xf); //Set all sensor output images
cv::namedWindow("image");
//Step 3: The camera starts to collect pictures
CameraPlay(hCamera);
while (true)
{
stImageInfoimgInfo;
//Step 4: Obtain camera image data
unsigned char *pbuff = CameraGetImageBufferEx(hCamera, &imgInfo, 1000);
if (pbuff == nullptr)
continue;
continue;
continue;
if (pbuff == nullptr)
continue;
//Use opencv to display the image, which contains image data of 4 sensors
cv::Mat image(imgInfo.iHeight, imgInfo.iWidth, CV_8UC1, pbuff);
if (image.empty())
continue;
unsigned int width = imgInfo.iWidth;
unsigned int height = imgInfo.iHeight;
unsigned int height = imgInfo.iHeight;
unsigned int height = imgInfo.iHeight;
unsigned int subWidth = width / 4;
unsigned int subHeight = height / 4;
cv::Mat image1 = image(cv::Rect(0, 0, subWidth, subHeight));
cv::Mat image1 = image(cv::Rect(0, 0, subWidth, subHeight));
cv::Matimage2 = image(cv::Rect(subWidth, 0, subWidth, subHeight));
cv::Mat image3 = image(cv::Rect(subWidth * 2, 0, subWidth, subHeight));
cv::Mat image4 = image(cv::Rect(subWidth * 3, 0, subWidth, subHeight));
cv::Mat image4 = image(cv::Rect(subWidth * 3, 0, subWidth, subHeight));
cv::imshow("image", image);
cv::imshow("image1", image1);
cv::imshow("image2", image2);
cv::imshow("image3", image3);
cv::imshow("image4", image4);
int key = cv::waitKey(10);
if (key == 27)
break;
break;
}
}
if (key == 27)
break;
}
}
cv::destroyAllWindows();
//Step 5: End image acquisition for the camera
CameraPause(hCamera);
//Step 6: Turn off the camera
CameraUnInit(hCamera);
CameraUnInit(hCamera);
}
int main(int argc, char *argv[])
{
process_multi_sensors_ckcamera();
return0;
}
This code will output images of 4 image sensors at the same time.There is a window showing images of 4 image sensors, and the other 4 images showing images of each sensor individually.
