Chromosome karyotype analysis has a wide range of applications in genetics, biology, medicine, and other fields. It is an important means of studying the transmission of genetic information in organisms, gene expression regulation, and disease diagnosis. Traditional chromosome karyotype analysis mainly relies on professional personnel to observe the morphology of chromosomes through a microscope, which is not only time-consuming but also susceptible to human factors. To improve the efficiency and accuracy of chromosome karyotype analysis, the development of a microscope chromosome karyotype analysis upper computer software is of great significance.

The development of microscope chromosome karyotype analysis upper computer software mainly includes the following aspects:

  1. Image Acquisition Module

The image acquisition module is a key part of the software, mainly responsible for obtaining chromosome images from microscope equipment. High-quality image acquisition provides a good foundation for subsequent image processing and analysis. To achieve this, we need to choose high-performance digital cameras or scanners and equip them with appropriate lighting equipment. In addition, the stability of the light source’s impact on image quality must be considered, so temperature and brightness control of the light source is necessary.

  1. Image Processing Module

The image processing module is mainly responsible for preprocessing the collected chromosome images, including denoising, smoothing, edge detection, and other operations. Denoising is to eliminate random noise in the image to improve image clarity; smoothing can eliminate minor fluctuations in the image, making the chromosome lines smoother; edge detection is to accurately extract the edge information of chromosomes for subsequent analysis.

  1. Chromosome Segmentation Module

The chromosome segmentation module is responsible for segmenting the processed images into individual chromosomes. This step is achieved by introducing morphological operations, region growing algorithms, and other methods. In addition, some thresholds and parameters need to be set based on professional knowledge and experience to better recognize chromosomes. The segmented chromosomes can be stored in a database for subsequent analysis.

  1. Chromosome Analysis Module

The chromosome analysis module is based on the segmented chromosome images for karyotype analysis. This module can automatically recognize information such as the arms, centromeres, and chromosome numbers of chromosomes, and calculate parameters such as the length and area of chromosomes. In addition, it can compare the results with human eye recognition to evaluate the accuracy of the analysis.

  1. Result Output Module

The result output module is responsible for displaying the analysis results to the user in a visual way. Through this module, users can intuitively view the analysis results, including the morphology, quantity, and order of chromosomes. In addition, the analysis results can be exported in common image formats for further processing and analysis.

  1. User Interface Module

The user interface module is the bridge between people and the software. It needs to provide an intuitive and easy-to-operate interface, allowing users to easily complete chromosome karyotype analysis. The interface should include the following functions: image import, processing parameter settings, analysis result viewing, and export, etc.

In summary:

The development of microscope chromosome karyotype analysis upper computer software has important practical significance. By introducing advanced image processing technology and artificial intelligence algorithms, the efficiency and accuracy of chromosome karyotype analysis can be improved, providing strong support for research in biology, medicine, and other fields. At the same time, the software can also be further optimized and expanded to meet the needs of different scenarios.

Development of an Intelligent Picking System for Robotic Arms Based on Machine Vision https://www.unicromtech.com/6876.html Mon, 22 Jan 2024 03:20:15 +0000 https://www.unicrom.cn/?p=6876 Intelligent manufacturing is gradually becoming an important development trend in the industrial field. Machine vision, as an artificial intelligence technology, is increasingly applied in the field of automation. This article will take the intelligent picking system for robotic arms based on machine vision as an example to explore the development and application of the system.

System Overview

The intelligent picking system for robotic arms based on machine vision mainly consists of four parts: the image acquisition module, the image processing module, the robotic arm control module, and the actuator module. The image acquisition module is responsible for capturing real-time images of the working scene, the image processing module performs pre-processing and feature extraction on the images, the robotic arm control module generates corresponding control strategies based on the results of image processing, and the actuator module is responsible for the precise movement of the robotic arm.

1、System Development Process

2、Requirement Analysis: Based on the actual application scenario, clarify the functions that the system needs to achieve, such as identifying target objects, precise picking, etc.

3、Hardware Selection: Choose the appropriate hardware equipment, including cameras, image processors, robotic arms, etc.

4、Image Processing Algorithm Design: Design appropriate image processing algorithms for the target objects in the requirement analysis, such as edge detection, morphological processing, feature extraction, etc.

5、Robotic Arm Control Strategy Design: Design the control strategy for the robotic arm based on the results of image processing, such as path planning, speed control, etc.

6、Software Development: Write the program code for image processing and robotic arm control to implement the core functions of the system.

Step 1: Image Acquisition
The first step in image processing is image acquisition. We can use cameras or other image sensors to obtain real-time images. In Python, the OpenCV library can be used for image acquisition. Here is a simple example of image acquisition code:

import cv2
# Create a VideoCapture object
cap = cv2.VideoCapture(0)
# Check if the camera is successfully opened
if not cap.isOpened():
    print("Failed to open camera")
    exit()
# Loop to get images
while True:
    # Read a frame
    ret, frame = cap.read()
    # If no image is read, exit the loop
    if not ret:
        print("Failed to read image")
        break
    # Display the image
    cv2.imshow('frame', frame)
    # Press 'q' to exit the loop
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
# Release resources and close the window
cap.release()
cv2.destroyAllWindows()

Step 2: Image Processing
After obtaining the image, we need to process the image to achieve the desired functions. For example, we can use image segmentation, feature extraction, and other methods to process the image. Here is a simple example of image processing code:

import cv2
import numpy as np
# Read the image
img = cv2.imread('image.jpg')
# Convert to a grayscale image
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
# Apply a Gaussian filter for blurring
blurred = cv2.GaussianBlur(gray, (5, 5), 0)
# Apply the Canny edge detection algorithm
edges = cv2.Canny(blurred, 30, 150)
# Display the original image and the processed image
cv2.imshow('Original Image', img)
cv2.imshow('Edges', edges)
# Press 'q' to close the window
cv2.waitKey(0)
cv2.destroyAllWindows()

Robotic Arm Control Program Code Writing

Step 3: Obtain the Status of the Robotic Arm
When writing the control program for the robotic arm, the first thing you need to do is to obtain the status of the robotic arm. We can write an interface program to communicate with the robotic arm controller. Here is an example of obtaining the status of the robotic arm using serial communication:

#include <stdio.h>
#include <pthread.h>
// Define the structure of the robotic arm status
typedef struct {
    int joint_positions[6];
    int gripper_position;
} ArmStatus;
// Function declaration
void *get_arm_status(void *arg);
int main() {
    // Initialize the status of the robotic arm
    ArmStatus arm_status;
    // Create a thread to obtain the status of the robotic arm
    pthread_t thread;
    pthread_create(&thread, NULL, get_arm_status, &arm_status);
    // Thread synchronization
    pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;
    pthread_mutex_lock(&mutex);
    // Loop to display the status of the robotic arm
    while (1) {
        printf("Joint 1: %d\n",
               arm_status.joint_positions[0]);
        // ... (Continue printing the status of other joints)
        // Delay
        sleep(1);
        // Unlock mutex
        pthread_mutex_unlock(&mutex);
    }
    // Wait for the thread to finish
    pthread_join(thread, NULL);
    return 0;
}
  1. System Integration and Debugging: Integrate all modules together, perform system debugging to ensure that all modules work together and achieve the expected effect.
  2. Application Fields of the System
  3. Manufacturing Industry: The intelligent picking system can be applied to material handling and assembly on the production line, improving production efficiency and reducing labor costs.

Development of a Serial Communication Upper Computer using QtQT https://www.unicromtech.com/6823.html Mon, 25 Dec 2023 02:47:26 +0000 https://www.unicrom.cn/?p=6823 In the modern field of industrial automation, serial communication technology is a very common method of data transmission. It is characterized by its low cost, high stability, and fast transmission speed, and is widely used in the communication between various electronic devices. To make better use of this technology, QT development offers an excellent solution. This article will detail how to implement a serial communication upper computer using QT development.

QT is a cross-platform C++ graphical user interface application development framework with a rich set of controls and powerful functionality. Utilizing QT for developing a serial communication upper computer enables data transmission, data display, and device control between devices. Here are the detailed steps for the development process:

Installing the Qt Development Environment

First, download and install the Qt development environment. Choose the appropriate version for your operating system and proceed with the installation. After installation, configure the relevant environment variables to ensure that Qt Creator runs smoothly.

Creating a New Qt Project

Open Qt Creator, select “File” – “New File or Project,” choose “Application” – “Qt Widgets Application,” then set the project name and save location, click “Next,” and complete the project creation.

Configuring the Serial Port

In the Qt project, you can use the QSerialPort class to implement serial communication. First, set the serial port parameters such as baud rate, data bits, stop bits, and parity. After project creation, open the mainwindow.ui interface design file, go to “Tools” – “Properties,” find the “Serial Port” tab, and make the necessary settings.

Initializing the Serial Port

In the mainwindow.cpp file, you need to implement the initialization of the serial port. First, include the header file:

cpp

复制

#include <QSerialPort>

Then, within the mainwindow class, define a QSerialPort object and implement the initialization function:

cpp

复制

m_serialPort = new QSerialPort(this);

m_serialPort->setPortName("COM1"); // Set the serial port name

m_serialPort->setBaudRate(QSerialPort::Baud9600); // Set the baud rate

m_serialPort->setDataBits(QSerialPort::Data8); // Set the data bits

m_serialPort->setParity(QSerialPort::NoParity); // Set the parity bit

m_serialPort->setStopBits(QSerialPort::OneStop); // Set the stop bits

m_serialPort->setFlowControl(QSerialPort::NoFlowControl); // Set the flow control

if (!m_serialPort->open(QIODevice::ReadWrite)) {
    qDebug() << "Unable to open serial port!";
}

Implementing Data Reception and Transmission

To enable data transmission between devices, you need to implement data reception and transmission functions. Add the following functions to the mainwindow class:

cpp

复制

void MainWindow::readData()
{
    QByteArray data = m_serialPort->readAll(); // Read serial port data
    // Process the received data
}

void MainWindow::writeData(const QString &data)
{
    m_serialPort->write(data.toLocal8Bit()); // Send data to the serial port
}

Connecting Signals and Slots

To make the serial communication function properly, you also need to connect signals to slots. Add the following code to the mainwindow class:
