Tech Hill has developed a Smart Building Concrete Radar Non-invasive Structure Scanner with solid-state LiDAR, mmWave radar, pyrogen, thermal imaging camera, and hardware image accelerator to detect the structure, strength, density, and steel reinforcement of buildings. Among its key technologies include a shape and texture shaping processor (US patented IP) engine in the hardware image accelerator. This obtains the crack map using preprocessing, image segmentation and feature extraction of the image data of the multi-array point cloud. Tech Hill has also developed a deep-learning neural network for crack detection to save time and labour.
