MUMBAI, India, Oct. 12 -- Intellectual Property India has published a patent application (202621068419 A) filed by Balkrishna Industires Limited on June 01, 2026, for Systems And Methods For Automated Tire Tread Depth Assessment.
Inventors include Yadav, Sushen Shekhar; and Rao, Prahalada.
The application for the patent was published on October 09, 2026, under issue no. 41/2026.
Abstract: An automated tire inspection system (100) and method (200) determine tire tread condition from a mobile-device-captured session package (120). A mobile device (102) captures a video (122) of a tread surface (112) of a tire (110) with camera pose data (124), camera calibration parameters (126), inertial sensor data (128), and operational metadata (130). A backend processing system (104) stores the operational metadata (130) in a hierarchical entity graph (150) and generates route-specific depth representations (160) using geometrically independent processing routes (170), including a photogrammetric reconstruction route (172), a monocular depth- estimation route (174), and a mesh reconstruction route (176). A common non-skid-depth extraction module (180) generates a depth distribution (182), fits a Gaussian mixture model (184), identifies a tread-surface component (186) and a groove-floor component (188), computes a non-skid depth value (190), and stores a tire tread condition result (192).
