My project is a greeting system that utilizes face detection through the Vision AI mode of the UNIHIKER K10. This system identifies guests and greets them through a speaker while displaying a welcome message on a 2.8-inch color screen.
The greeting system is built around the UNIHIKER K10, which includes a camera, a microSD slot, a speaker, and a 2.8-inch color screen. A code block for the greeting system is generated using the programming tool “Mind+,” which works on a PC, and is then uploaded to the UNIHIKER K10. The code block captures guest images from the camera and detects their faces. When a guest's face is detected, the system plays a greeting message through the speaker, saying "Welcome to the Hotel." This greeting audio data is stored on the microSD card. Additionally, the code block displays a greeting message and details about the detected face information on the 2.8-inch color screen.
Step 1: Create the code block
The code block for the greeting system uses libraries such as "cache text," "camera show," "face detection," "get face attributes (length, width, center x/y)," and "play TF card audio" in Mind+. The code block is structured as follows:
Step 2: Create guest images
Guest images are representations of hotel guests. These images feature a lady figure attached to a wooden stick and are scanned using the camera of the UNIHIKER K10.
Step 3: Create voice data
The greeting voice message is “Welcome to Hotel,” and it plays when the system detects the face of a hotel guest. This voice data is saved on a microSD card using the Audacity app. The Audacity app records the voice and saves it as a file after editing the voice data.
Step 4: Upload and run the code block
To upload the created code block to the UNIHIKER K10, use the Mind+ app. Click on “Connect Device,” select the “COM9-UNIHIKER K10” from the drop-down menu, and then press the “Upload” button.
Demo:
The Greeting System operates as follows: It scans the guest's image, and when it detects a face from the image, the system displays a green rectangle around the detected face on the 2.8-inch color screen. At the same time, it plays the voice message “Welcome to Hotel” from the microSD card.
