Due to interference sources such as dial cleanliness, light pollution, light angle, and severe weather during the reading process of outdoor instruments, a design of outdoor instrument cleaning and reading devices based on wireless positioning is proposed. The focus is on the influence model of reading distance on outdoor instrument reading, composition, deployment, and positioning accuracy testing of wireless positioning. The feasibility and utility of wireless positioning in outdoor instrument cleaning and reading are verified through practical applications. Outdoor instrument cleaning and reading devices can be operated independently through wireless positioning and laser rangefinders. The entire process does not require edge recognition, image rotation, translation, or deformation conversion of instrument panel images, achieving accurate reading and reliable reading of outdoor instruments. This reduces the outdoor work intensity and improves the efficiency for workers.
