The invention relates to a tire lateral force detection device based on binocular vision and a resolving method, the device is composed of a base frame, a linear loading adjusting mechanism, a rotary loading adjusting mechanism, a simulation pavement assembly, a visual detection system, a sensor and a tire, and the devices are fixedly installed according to corresponding positions; by applying a relative motion principle, rotation of a simulated road surface replaces steering of a tire, so that lateral deviation motion of the tire is realized; the sensor collects the vertical load borne by the tire; the visual detection system detects the rolling deformation condition of the side wall of the tire; the tire side stiffness is calculated through data collected by corresponding sensors, and the tire lateral force is calculated through a proposed new lateral force calculation method; the device can simulate tire sidewall rolling deformation on different road surfaces, solves the problems of difficult installation
