In this paper, we propose a multi-sensor based incline measuring system. The systems include: g-sensor, e-compass sensor, and image-based incline measuring system install in a same structure, the solar cell system and wireless transmission system (zig-bee) also install in the same structure. The g-sensor and image-based incline measuring system use to measure the incline angle and the micro-vibration, and the e-compass sensor to measure the angle of rotation. The image-based incline measuring system include: a laser projector, a measuring board and a camera, and the system use the characteristic of laser, and the laser projector hanging on structure project a laser beam on the measuring board vertically. The camera captures an image to identify the coordinate of laser spot, and use the coordinate of laser spot to calculate the actual incline angle. The results of incline angle combine two different sensors to increase the accuracy of measurement result.
