Recent progress in free space estimation provides precise segmentation between the ground and obstacles on flat plane. However, it remains challenging on nonflat plane, especially with the varying latitudinal and longitudinal slope or in the case of multiground plane. This letter presents a well-integrated framework for free space estimation in this challenge. Our approach couples an improved V-disparity...

The adsorption of diesel oil in seawater on biodegradable adsorbing material and the influencing factors such as salinity, pH and temperature were studied. Results showed the adsorption of diesel fitted the second-order reaction model, and the saturated adsorption capability was 6.69g/g which can be reached in 10-20min. The diesel oil removal efficiency increased with the increment of salinity and...
