High-integrated structured light 3-D measurement system based on ARM

This paper proposes a high-integrated structured light 3-D measurement system based on ARM9 development platform and embedded Linux system. System scheme, system control and system measurement were investigated. First embedded operation system based on hardware platform of S3C2440 was analyzed, peripheral expansion device camera and serial controlled projector were used to constitute measurement system. Then image acquisition was realized through Video for Linux, projector was controlled through serial communication. Finally coordinates of object were obtained by structured light 3-D measurement method. This paper describes the hardware and software of measurement system; experimental results show that miniaturization and integration were realized in structured light 3-D measurement system.
