present Nericell, a system that performs rich sensing by piggybacking on smartphones that users carry with them in normal course. To monitor road and traffic conditions in such a setting, Mohan et al. present experimental results from real urban driving data that demonstrate the usefulness of the system. The objective of the research is to improve traffic safety through collecting and distributing up‐to‐date road surface condition information using mobile phones. Analysing from the research activities, it is certain that this area will gain more importance in recent future. Smartphone sensors are gaining importance in this field, as they are cost effective and also increase scalability. present a detailed survey of methods for detecting road conditions. Another scientific study field is that using smartphone cameras together with the developing technologies has given the opportunity to achieve new study fields that have not been made before. Smartphone cameras used for acquiring image instead of conventional cameras have opened a new scientific study field. Cameras on mobile phones are as capable as compact cameras that we use in our daily lives. The characteristics of Olloclip lens used in this study are presented in Ref. Additionally, these lenses are cost efficient compared to conventional fisheye lenses. Since fisheye lenses integrated with mobile phones are lightweight and easy to use, they are advantageous. Fisheye lenses that are compliant to mobile phones are one of these new equipments. Some of those lens kits are presented in Refs. Other than these devices, there are tele, macro and fisheye lenses that can easily be integrated to the smartphones. Cameras and other integrated additional devices are found in almost every smartphone. Nowadays, mobile phones are more than a device that can only satisfy the communication need between people. The use of smartphones with fisheye lenses will give the possibility of practical applications to ordinary users in the near future. Moreover, as verified in this study, the accuracy of fisheye lenses used in smartphones is better than conventional fisheye lenses. The dimensions of fisheye lenses used with smart phones are getting smaller and the prices are reducing. This experimental study shows that Olloclip 3 in one fisheye lens developed for mobile phones has at least the similar characteristics with classic fisheye lenses. For this, standard calibration of ‘Olloclip 3 in one’ fisheye lens used with iPhone 4S mobile phone and ‘Nikon FC‐E9’ fisheye lens used with Nikon Coolpix8700 are compared based on equidistant model. Fisheye lens equipment used with mobile phones was tested in this study. In addition to this advantage, it is experimented whether fisheye lens and mobile phone combination can be used in a photogrammetric way, and if so, what will be the result. When you pick up the camera and install this super wide-angle lens to the mobile phone, you will immediately become the focus.Nowadays, mobile phones are more than a device that can only satisfy the communication need between people. Nowadays, the mobile phone shooting has become so popular and this is definitely the best partner for the mobile phone shooting. The equipped 37mm/1.46in mobile phone adapter clip is directly attached to the camera of the mobile phone after the lens is mounted, allowing your phone to change the SLR in 1 second. As a compact and convenient professional lens, it not only has a powerful professional-level effect but also has much more portability than a camera interchange lens. The 49mm/1.93 in UV port guarantees sufficient light transmittance, which not only ensures the brightness of the screen but also maintains the clarity of the picture. The lens adopts high-quality optical glass and multilayer optical coating that can effectively solve the defects of the clear focus yet fuzzy edges the phones have in the past. The camera's viewing angle can be expanded by 60% without affecting the shooting quality of the mobile phone when the lens is connected to the mobile phone through a multifunctional mobile phone adapter clip. It has a cool appearance and precise parameters and fine imaging effects. Mobile Phone Universal 49MM UV Super Wide Angle + Macro Lens, Effectively solves the problem of the hidden corner of the wide-angle lens on some mobile phones This is an external lens dedicated to professional photography equipment such as digital DV/DC. Macro lens can take clear photos of small objects 0.67 Wide-angle lens can shoot larger range of scenery 180 degrees of the scene can be captured by Fisheye lens, which can let you enjoy the unreal world. Three Great Lenses in One Kit: Three awesome lenses to help you get the most out of your mobile photography.
