MOBILE MAPPING SYSTEM (IMS3)
IMS3 Mobile Mapping System (MMS) is high-efficient, easy-to-use, end-to-end solution that provides tremendous flexibility in collecting, accessing, displaying, and analyzing 360° geo-referenced spherical imagery. IMS3 is purely an optical MMS based on Iwane Camera Vector (CV) Technology. The mobile mapping system by Iwane does not rely entirely on GPS. It is image based MMS and perfectly suitable to map urban and rural area. IMS3 system is the only MMS system which can provide a unique geo content using which one can extract meaningful information (3D Map & coordinates), create by-products like 3D computer graphic model, extract road markings, ortho photo of road surface, road markings and other geo digital content for web like unique intelligent 3D street views.
Simple, Robust and Flexible
IMS3 is a very simple and robust MMS system. User can mount all the MMS equipment very quickly on to a shooting vehicle for example less than an hour. It is also designed in way that users can easily calibrate the distance between two cameras and between top camera and center head of GNSS. In order to work in extreme hot condition, we have designed a metallic cap which protects camera from direct heat and act as insulation. This facilitates the use of IMS3 system even in harsh and hot conditions.
The concept is to use minimum sensors and can able to extract much more meaningful information from MMS content. The strength of IMS3 lies in post processing and application software’s. IMS3 mount design is so much flexible that it can be mounted on any kind of vehicle like land cruiser, wagon, sedan, pickup truck, and small car and that too in a very less time.
Components and Acquisition
IMS3 consist of two sets of omni-directional cameras (top & bottom) with 6 CCD (2MP×6) of which total resolution is 2,700 X 5,400 Pixel ( Approx. 12 M Pixel /Frame ) at Maximum. It can capture 16 frames per second. IMS3 has also accelerometer for vertical inclination, GPS & antennas for positioning.
The optimal speed for data acquistion is less than 60km/hr. However, it is also possible to collect data at the speed of 100km/ hr at maximum. Normally the speed can vary but it does not affect in the accuracy of the MMS datasets.
Generally one driver and operator can acquire data but it is also poissible for driver alone to acquire MMS data because driver can set all the paramters before the start of data acquistion and just click stop at the end of shoot.
The capacity of stream data in shooting by two cameras is around 20-30 GB/km and user can shoot long distances by just changing the HDD’s.
