If for some bizarre reason you would want to stick to cameras only, you could use 2 cameras and calculate the distance to various points based on the difference between the images. Thats called stereoscopy and is precisely what gives our brains depth perception. The issue is that this process is expensive computationally so I'd guess that it would be cheaper to go back to lidar.
Subaru does that!
