The most frequently mounting problems of the roads are facing is Damaged road conditions. For many
reasons like earth quakes, accidents on roads, wear and tear of top layers of roads make the drivers to drive
on those roads. Unexpected Obstacles on roads may cause number of accidents. Also because of worse road
conditions, the vehicles consumes a lot of fuel unnecessarily. For these are the reasons it is very significant to
get the data of such damaged roads. POTHOLES are the crack-up’s on roads that are formed on the roads for
many reasons where the top road layers will get tattered by heavy traffic. Once after formation ofpothole the
size of hole will keep increasing till we ready that road or repair the pothole, which is main causes for Road
mishap’s. Potholes on roads are particularlyaffects for drivers rushing at high speed. At high speeds a driver
almost inconceivably can notice the potholes on road surface. None the less the drivers may see the potholes
before they cross it, it normally will be too late for a driver to respond to the pothole. A sudden turn or
sudden braking will mostly causes car roll-over. Triggered to the above reasons, we introduced a system that
detects potholes and the proposed system will produce the three dimensional data of potholes and save data
information data and we can retrieve that data and get pothole image. In this paper we use different edge
detection techniques to detect potholes on road. Canny edge detection technique, the most important
algorithm we used here to detect potholes. It detects potholes very accurately and stores the data for future
maintenance of roads. We use a web camera to record the roads and click the images because comparing to
the costly high speed Three Dimensional traverse scanning equipment, web camera is cheap and expensive.

This has crystal rectifier to several accidents inflicting loss of lives and severe injury to vehicles. several
techniques are planned within the past to sight these issues victimization image process ways. however there
has been very little work specifically dispensed for detective work such problems with Indian roads. Potholes
will generate injury like pneumatic alloys injury, jolt and injury of bottom side of vehicles, car or bike
destructions, and big mishap’s. Hence, precisely and hastily detective work potholes should be one amongst
all of the necessary processes of detecting correct methods in ITS services. Many attempts many efforts are
created for progressing the technology which might mechanically sight and acknowledge potholes. during
this project, a hole 2 dimensional (2D) pictures primarily based hole detection technique is employed for
rising the prevailing technique. this method proposes a system Automatic sight the amount of recently
revealed papers addressing crack detection Associate in Nursing classification of asphalt surface affliction
displays an alluring interest during this space. A recent journal, a stratified gift in [1], that cope with
disclosure of roads and inclinations. During this paper, unique groundwork is planned for separating roads
pictures in an exceedingly stratified presence so that may divide the subsequent things. The analysis displays
that the accession during this paper are able to do a glad output on the varied images of road. The lanes
square measure disorganized, that square measures additional advanced more than the organized roads. In [2]
the multi scale accession supported Andre Mark off odd field is planned to section adepts in road concrete
surface pictures. Adepts square measure increased employing one dimensional filter of Gaussian used for
smoothing and so handled by the filter that matches two dimensional to sight them. Complete sixty four road
or lane asphalt layer pictures exhibiting many adepts sorts square measure thought of for experimentation,
manufacturing a qualitative analysis. Characteristic details of image or sort detector accustomed will click
them aren’t given. Another paper [3] evidences the problem of detective work cracks of but three millimeter
dimension once victimization edge detectors. A non-sub sampled contour let rework that has been ratified in
[4] for sight adepts, whereby restricted collection of developmental outputs are conferred. A whole
methodology to mechanically sight and characterize top surface defects are planned at [5], victimization gray
scaled pictures that are clicked with line scanning cameras where lasers lit them throughout road analysis
executed employing an image acquisition system with high speeds. Detection of Adepts uses tentative texture
property activity for every picture. The outputs conferred square measure encouraging, however
developmental analysis doesn’t brace excellence of number of cracks within same picture. In paper [6],. NN
technique is employed. The machine-driven pavement defect detection will solely establish crack kind
defects. To classify defect, a multi-layer perceptron neural network (MLPNN) is employed. NN is employed
to segregate the pictures into four classes: defect-free, crack, joint and bridged. Experimental results square
measure performed on real road pictures that square measure labeled by human operators. There square
measure additional further filters needed for this method. In paper [7], Vision-based approaches square
measure accustomed address functionalities like detection of marking lanes, recognition of traffic signals,
