If they do it would be a horrible mistake.
The decision will not be based on the right to camp, as there is no such right. It will be based on whether being homeless is a status and whether the ordinance forbidding sleeping outdoors in a public space criminalizes that status and is therefore a violation of the 8th amendment forbidding cruel and unusual punishment.
That it is even being considered under that amendment is thanks to the Warren court which gave us a decision referred to as Robinson which decided being a drug addict was a status and unlike the conduct of possessing, using, or dealing drugs could not be regarded as a criminal act. Which meant it was cruel and unusual to treat addiction as a crime. THANKS EARL WARREN! Sarc.
