IMS3 MMS - Iwane Laboratories


Open the future by geo imaging advanced technology


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.




IMS3 overcomes the challenges of mapping linear features to a high level of accuracy. Accurate vehicle positions can be obtained using the combination of two technologies: Camera Vector (CV) and GNSS receiver establishes a geospatial position.





Iwane pipeline from capturing the images to processing and surveying consists of the following steps:

- Data Acquisition

-  refine Post production: Over 95 % automatic processing of the recorded imagery

- Geo-referencing of the result by using Ground Control Points ( GCP)  / GPS / or both.

- Surveying & measuring into your GIS system based on Images.

- Disseminate MMS data on Web



Post Processing

After the data acquisition, Iwane refine post production tools (95% automatic) are used to extract 3D feature points from identified features in the image sequence and respective camera position & posture is derived by using Iwane post processing software (CV maker).  The CV and GPS trajectory is fused together to geo reference all the video/ images in the sequence.





In the process of postproduction, image quality can be enhanced and output of the MMS content will be free from any vibration and dead hole i.e. a complete all surrounding image.




The capacity of processed data is around 5-8GB/km in average, however, it is possible to adjust the capacity of final output flexibly based on customers’ requirement or hardware environment by skipping frames or decreasing image size.


Since the correlation between the image sequences is very high, therefore relative accuracy is always higher in IMS3 system. The relative accuracy is irrespective of the quality of GPS. IMS3 supports direct & indirect geo referencing. It means that the positional accuracy can be increased even after data acquisition. This can be done by registering survey control points inside the image and geo reference all the sequence again. IMS3 can import post processed GPS trajectory (from external high end positioning device used at the time of data acquisition) in CV Maker software and geo reference the image sequence.




We offer cm level of accuracy both in case of positional & relative accuracy. Relative Accuracy is 2-5 cm (10-15 m from the center of camera). Positional accuracy depends on type of positioning device and quality of GPS data at the time of data acquisition. In our accuracy test’s using kinematic post process GPS data, we have achieved less than +/- 15cm cm (X, Y) and (+/- 20cm) Z of the positional accuracy nearby the camera (15-20 meter from the camera). With GPS + IMU/INS, positional accuracy is achieved less than 10 cm on Highways.

Users can easily check the positional & relative accuracy results by simple visualizing score graph. If required , user can rectify or enhance  accuracy by further processing e.g. import Control Points ( CP's )  and enhance the positional accuracy or jump to specific frame with low accuracy  and delete  moving feature point on moving objects ( e.g. car ,trucks , etc..)




Use of optional GPS/IMU with IMS3

Iwane MMS system is highly flexible to an extent that it can import external high accurate GPS sensor trajectory data and can geo reference videos /images using the time stamp. The fourth reference frame or the final position of GPS is derived from imaging techniques. The GPS position can always be seen in the footage. The center of the GPS can be easily calculated by clicking on the pixel of the footage only. In this way, we can calculate not only the coordinates of GPS but also parameter like distance (offset) between the camera center .Some of the GPS device which we have used with our MMS system are Hemispehere GPS ( A325 GNSS ), Leica GS14, Garmin 18x, Novatel SPAN CPT ( GPS +INS ), Applanix ( GPS +IMU ), etc. In short, user can choose GPS device as per the positional accuracy requirement.




Surveying and Measuring

Since IMS3 has two cameras, relative measurement is possible even in the areas with no GPS data or signals e.g. in urban area or tunnels. This is because the distance between two cameras is fixed and known scale helps to perform relative measurements. User can measure every point which you see in the images with ease and precision. Just click the point you want to measure in one image, and the system will track the same point in neighboring images to give the resulting 3D coordinates automatically. Measure in epipolar mode for highest precision: clicking a point from one image and then click the same point from different image will give you precise 3D coordinates.




With Iwane technology, less field supplementary survey is required! The frame rate per second and angle of views also ensures that every object is seen from different angles and in many subsequent images. Therefore it is very little that you can miss!

Geo Referencing

We use three ways to geo reference our MMS data.


(a) Direct Geo referencing:  The Smoothed, Best Estimated Trajectory” (SBET) by GPS + INS will be calculated and used a an ideal trajectory .


(b) In-direct Geo referencing:  If we cannot rely on SBET which we   calculate from GPS+ INS data, then in such case we use manual surveyed ground control points at certain interval on the same or opposite side of the road and geo reference images/video's.


(c ) Combination of SBET and GCP’s.

Although the system is totally independent of GPS during the data acquisition, a high accuracy GPS antenna is integrated with the system which can be used to compute geo referenced solutions without GCPs or to reduce the number of GCPs required.




After registering ground control points (GCP) to the sequences of images and using an advanced bundle adjustment, both the 3D surrounding and the system positions and orientations are known in the coordinate system of the GCPs. The accuracy of the geo referencing is such that we can easily identify outliers in the GCP dataset, thus enhancing the final result.





Mapping Underground (Tunnels)

Since we work with images, therefore we need some light to operate. But once we have enough light, the Iwane system can be used in tunnels. If there is only a small amount of light, we can work with reduced speed to be able to use longer shutter times. The amount of field work will greatly reduce, limiting the time the tunnel is not available for its normal use.





Mapping Railroad

IMS3 can quickly acquire geo-referenced 3D spatial data on railway infrastructure from a platform mounted on a moving rail car. Surveying an area of interest quickly, safely, efficiently and without the larger  scale interruption necessitated by traditional survey methods.


All surroundings including the railways tracks and asset can be mapped and measured. This is very helpful to map and maintain all the assets nearby the road, rail corridor monitoring, extracting height differences, measure and find all the clearances, measure height and proximity of trees and man-made objects surrounding the rail right-of-way.




Users and Application

IMS3 is used to populate GIS database Development, Asset Management, Simulation and Mission Planning, Survey and Analysis, Situational Awareness, Virtual Tourism, Property Display, Tracking and Navigation, and Other Tasks that cannot be conveniently accomplished without out-of-the-box any GIS Software.

A few of the government department who are using IMS3 system are Public works / Municipalities, Cadastral & Mapping Bureau, Land Management, Infrastructure, Housing, Development Ministry of Transportation, Planning Departments, Defense Sector, Housing Authorities, Disaster, Prevention and Mitigation.

Finally, IMS3 provide a platform to create 3D GIS and that can be used for many purposed like smart cities, e-governance, etc.
