Aqua-Vision (An underwater panoramic camera with computer vision and analytics)

In the present social media-bound lifestyle, capturing memories and keeping them accessible is gaining a significant demand globally. For this purpose, a robust, portable camera system for recreational or commercial purposes can be of substantial advantage to society. Aqua-Vision intends to bring an affordable underwater camera system with various innovative features to the hands of consumers. The smart module consists of a waterproof gimbal camera that can be used underwater, providing a hassle-free and reliable user experience and offers rotary motion along two axes. The camera features various general modes like panorama, burst shot, and smart modes using inbuilt computer vision algorithms. The gimbal camera setup can be controlled and switched remotely between all possible modes using a mobile application. All the above features will allow the user to capture photos/videos in any possible setup and use the camera module for various applications. The advent of such innovative, convenient, and robust modules will help cater to the market demands effectively.

Using GMSL Technology for Transmitting Stream of High-Quality Video Data

The article is devoted to the description and research of technologies for data flow transmission from video cameras designed for use in modern cars. The paper provides a theoretical analysis of the most popular wired and wireless data streaming technologies, such as Gigabit Ethernet and Wi-Fi. Analysis of the most important characteristics showed, that the mentioned technologies are not effective due to their significant shortcomings, which are critical in the production of cars, and will not allow their usage. The main disadvantages of Gigabit Ethernet technology are the lack of guarantees of full delivery of transmitted data. Given that the data obtained can be used for self-driving control systems, the technology cannot be used for transmitting the data stream to the camera, as there will be a possibility of endangering the safety of the passenger and accidents to the vehicle. Disadvantages of Wi-Fi technology include low data rates and lack of reliable protection against electromagnetic interference. Given the advantages and disadvantages of the above technologies, it was decided to abandon the possibility of their usage and consider suitable options. It is shown, that in the considered conditions, the most expedient solution for data transmission from the video camera is GMSL technology, which makes it possible to significantly increase the resistance to electromagnetic interference, the overall transmission rate, and the quality of the transmitted data. The technical features of GMSL technology, in particular SerDes technology, which is one of the main components of the above technology, are considered. For SerDes technology, the process and features of converting a parallel data stream into a serial, data transmission, and inverse data conversion into a parallel form are described. The usage of this technology makes it possible to transmit data over a distance of up to 15 meters (without significant loss of quality). Described is a method of encoding input data in the format 8b/10b. This encoding makes it possible to ensure the stability of data transmission and their overall resistance to electromagnetic interference. This is achieved by noise of the useful carrier signal. Describes the possibility of restoring the clock signal using the CDR block after receiving data on the differential pair, as it does not contain a separate line for this signal. At the same time the problem of current and voltage balance is solved. The methods of controlling the video camera module and SerDes components using I2C and UART interfaces are shown. The peculiarity of the control signals is that they can be directed in different directions due to the duplex transmission channel. The expediency of using GMSL technology in a device that implements data transmission from the camera module is considered. The advantages of using the described technology and their compliance with the established requirements are given. It is proposed to implement the ability to control the mode of operation of the camera from the control device using GMSL technology.

Rancang Bangun Sistem Pemberian Pakan Ikan Secara Otomatis Berdasarkan Perilaku Ikan Menggunakan Kamera Berbasis Mini PC

This research was conducted because fish feeders are often forgotten by fish owners, so the researchers created an automatic fish feeding system using the Raspberry Pi, Camera Module-v2, Accelerometer Sensor, and Servo Motor. The way this tool works is the reading of water ripples carried out by the accelerometer sensor which later can get a trigger value to turn on the camera module-v2 and take pictures of the fish, the resulting image will be processed to identify the fish's mouth and calculate the number of fish mouths that appear to the surface. When the system can detect the number of fish mouths, the fish is hungry and the servo motor will open the food valve to release the fish food, but when the number of fish mouths is 0 or not detected, the servo motor will not open.

RASPBERRY PI SEBAGAI PEMANTAU RUANG LABORATORIUM MENGGUNAKAN METODE PEREKAMAN TERJADWAL BERBASIS DATABASE

Practicum activities in higher education especially in State Polytechnic of Malang are generally carried out in a laboratory and based on a predetermined schedule. In the practicum activities are usually used equipment and practical materials borrowed by students from cabinets or warehouses for storage of tools and materials. In addition, in the laboratory where the practicum is carried out there are equipment and personal belongings belonging to students or teachers. From the experience that has happened, some campus-owned lab equipment and materials have been damaged and lost, or the personal property of students or teachers who have been left behind and even lost. Monitoring and recording using ordinary cameras has a disadvantage, that is, we cannot adjust the recording schedule that changes every day based on the space usage schedule. And record data is still one part or not grouped based on space usage schedule. Therefore, it is necessary to make a system that can monitor and record the process of laboratory practicum activities based on space usage schedule. In this study a system will be made using the embeded Raspberry Pi system and a camera module with MySQL as the database, this system is designed and created so that it can be used to record the laboratory practicum activities based on the space usage schedule in the database

Robotic Search and Rescue using Human Detection System

In this Technological advancement period, advanced construction improvements lead the formation of skyscrapers and homes which expanded the dangers of losing life because of natural and manmade catastrophes. In this system, we are proposing a radio-controlled bot that can identify live human beings from which are in the inaccessible region. Python libraries are used in Raspberry Pi microcontroller having Camera module to catch pictures of objects around it. This paper discusses about the mentioned system. The project takes live image samples and sends it to a network where this images can be accessed through a device. This images can be used for human detection. PIR sensor is used for the detection of human being trapped under debris. Whenever a human is detected the bot will send GPS co-ordinates to the device.
