Innovation Solution
A smokestack inclination detection system that uses laser light to generate shape information and detect inclination based on reflected laser light, incorporating a light source unit with a light illumination and receiving unit, and an information generation unit to produce shape information, which is then used by an inclination detection unit to determine the smokestack's inclination.

Engineering Contradiction Analysis
1Measurement precision
If a corrosion scanning system with laser device and positioning arm is used, then corrosion detection capability is improved, but inclination detection capability deteriorates (cannot recognize inclination)
Solution Approach 1:
The laser scanning system is enhanced to perform multiple functions: both corrosion detection (surface state measurement) and inclination detection (shape information analysis). The same laser device and positioning arm used for corrosion scanning are also employed to capture shape information, allowing the system to derive both surface conditions and structural inclination from the collected data without requiring separate dedicated systems.
Solution Approach 2:
Shape information serves as an intermediary data element that bridges the gap between raw laser scanning data and inclination detection. The system first generates shape information from reflected laser light, then uses this intermediate representation to calculate inclination angles, enabling inclination detection to be integrated into the existing corrosion scanning workflow.
2Measurement precision
If laser light is used for surface scanning, then surface corrosion can be detected, but three-dimensional shape and inclination information is lost
Solution Approach 1:
The system transitions from two-dimensional surface scanning to three-dimensional shape capture by utilizing the positioning arm's spatial coordinates and the laser device's angular information. This dimensional enhancement allows the system to reconstruct the smokestack's three-dimensional shape from the reflected laser light data, enabling inclination detection while maintaining surface corrosion detection capabilities.
Solution Approach 2:
Shape information is generated in advance during the laser scanning process, before inclination calculation is performed. By pre-processing the reflected laser light data to extract shape characteristics (such as contour lines and surface geometry), the system prepares the necessary information foundation for subsequent inclination analysis, ensuring both surface and shape data are captured efficiently in a single scanning operation.
