This utility model discloses a tunnel wall ring reinforcement forming device, relating to the field of tunnel ring reinforcement processing technology. The tunnel wall ring reinforcement forming device includes an integrated steel frame, which houses a primary forming mechanism, a straightening mechanism, a matrix laser sensor, and an encoder. The matrix laser sensor is located on the reinforcement inlet side of the primary forming mechanism. The primary forming mechanism includes a pair of driving wheels and driven wheels, with the driving wheel connected to the encoder and the driven wheel connected to a linear avoidance actuator. The straightening mechanism includes a pair of driving wheels and driven wheels, with the driven wheel connected to a linear avoidance actuator. The matrix laser sensor and the encoder are electrically connected to a control box, which is controlled by the linear avoidance actuators. This tunnel wall ring reinforcement forming device can avoid sleeve collisions, improve ring reinforcement forming accuracy, and ensure forming quality.

The invention relates to a display screen correction method and device, equipment and a storage medium, the pixel color components are divided into two types and collected by adopting different exposure time by analyzing the brightness ratio of each pixel color component of a display screen in a specified display state, short exposure or a preset value is adopted for the pixel color component with the small brightness ratio to shorten time, and the display screen correction efficiency is improved. And if the brightness ratio is not small, standard exposure is adopted to ensure the data accuracy. Correction parameters are determined according to the two types of data, display screen correction is achieved, the collection time is shortened, and the correction effect is guaranteed.
