Contemplate over improve  and write a program in C++ that includes relevant libraries:

    Accessing Camera Feed:

    Initialize the camera and set up the feed.
    Use image processing techniques to detect movement in a specified area.
    Once movement is detected, capture the image and store it in memory.

    Overlaying Sensor Data:

    Obtain sensor readings for temperature, voltage, humidity, and other relevant parameters.
    Overlay the sensor data onto the captured image using appropriate visualization techniques.

    Sending Data as SPI Serial:

    Set up the SPI serial communication with the microcontroller or computer.
    Packetize the image and sensor data, and send it over the serial communication.

    Receiving Data and Translating to Picture:

    Set up the serial communication on the receiver side to receive the packetized data.
    Unpack the data and translate it back to an image with overlays for temperature in Celsius degrees, voltage in volts, and relative humidity in percent.

Here's a high-level pseudocode for the program in C++ that implements the functionality you described:

cv::Mat processedFeed;

}

cv::putText(sensorData, "Temperature: " + std::to_string(temperature), cv::Point(20, 30), cv::FONT_HERSHEY_SIMPLEX, 1, cv::Scalar(0, 255, 0), 1);
