Abstract:
Understanding the 3D space is crucial for autonomous vehicles for planning and navigation. Traditionally autonomous vehicles use LiDAR sensor to 3D map its environment. LiDAR sensor data are often noisy and sparse making it not fully reliable for real-time applications like autonomous driving, thus redundant such sensors are used for the purpose. The array of cameras in an autonomous vehicle purposed for detection and tracking can be reused for depth estimation as well. In this paper, an unsupervised monocular depth estimation approach for autonomous vehicles which can be used as redundant depth estimators replacing multiple LiDAR sensors. Here, a deep learning based method is used with a multiscale encoder-decoder network to estimate depth. Target view among the stereo pairs is reconstructed by inverse warping the source view using geometric camera projection. The network is guided by the stereo positive–negative(SPN) loss which minimizes the loss between reconstructed view and corresponding stereo ground truth and, also maximizes the loss between reconstructed views and corresponding opposite stereo ground truth. The proposed approach shows state of the art accuracy in autonomous driving dataset KITTI.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
