In this paper, we present detailed studies for measuring the production cross sections and setting model independent limits on the anomalous magnetic and electric dipole moments $\tilde{a}_\tau$ and $\tilde{d}_\tau$ of the $\tau$-lepton, through the tau pair production channels $pp \to p\tau\bar \tau \gamma p$, $e^-p \to e^- \tau\bar \tau \gamma p$ and $e^+e^- \to e^+\tau\bar \tau \gamma e^-$ via the $\gamma^*\gamma^* \to \tau^+\tau^-\gamma$ subprocess. Measurements of the anomalous electromagnetic couplings of the tau-lepton provide an excellent opportunity to probe extensions of the Standard Model. We found that of the three colliders considered LHC, FCC-he and CLIC, the prediction of the future CLIC at high energy and high luminosity should provide the best sensitivity on the dipole moments of the $\tau$-lepton $\tilde a_\tau=[-0.00128, 0.00105]$ and $ |\tilde{d}_\tau({\rm ecm})|= 6.4394\times 10^{-18}$ at the $95\%$ Confidence Level.
