The team just had dinner!

A neural network has been chosen to perform image segmentation. Our dataset is being manipulated to train properly on the model.

We are also working on transforming an image from standard car view to bird's eye view using OpenCV's perspective transform.

Xinyu Guan is working on loading the images into more immediate memory to be used in training the network.
AtlasCV 15 Jan 2019, 5:03 p.m. EST
For the network, we are using VGGNet with an additional deconvolution layer on top. The deconvolution layer is used to increase the resolution of the VGGNet network output to our desired output.

Interesting note by Zheng Xu: When transforming perspective from driver perspective to bird's eye perspective, it's better to keep the top portion of the road constant while shrinking the bottom of the road. This helps us keep more detail in the original image.

Shreyan Jaiswal is working on determining the curvature of the road given a perspective warped image.

Oshadha Gunasekara, contrary to popular belief, is not just wasting time. He is working on determining a control method for the buggy given calculated lane/road lines.

Having WiFi issues with the TX2 :O

We were able to fix wifi issues with the TX2!

Shane worked on training the neural while he was on a plane! What a baller! 😎😎😎

Frank was able to capture some test bagfiles using the D435 camera today to test our CV pipeline.

We can now use BOTH keyboard and mouse on the TX2 using the Dell Monitors! O:
AtlasCV 16 Jan 2019, 10:06 p.m. EST
OpenCV is "somewhat" installing on the TX2!
AtlasCV 17 Jan 2019, 12:37 p.m. EST
Most dependencies have been successfully installed on the TX2.
AtlasCV 17 Jan 2019, 12:38 p.m. EST
On the CV side of things, we have fully integrated the D435 onto ROS and are able to run our perspective transform natively on ROS.
AtlasCV 17 Jan 2019, 12:39 p.m. EST
Further, we are able to identify lane lines given a segmented image and calculate an approximate curvature of the road.
