Abstract:
Inspired by the unique structure of insect compound eyes, a multi-channel image acquisition system is designed to photograph a cylindrical panorama of its surroundings with one shot. The hardware structure consists of an embedded ARM system and one array of 16 micro-image sensors. The system achieves the synchronization of captured photos in 10 ms, as well as 10 f/s video capture. The software architecture includes the TCP/IP protocol, video capture procedures in “Poll/Read” or “video streaming” modes, thread pool monitoring in multi-threading mutex, synchronization control with the“event” “mutex signal” and “critical region” functions, and a synthetic image algorithm characterized by its portability, modularity, and remote transmission. The panoramic imaging system is expected to be a vision sensor for mobile robotics.
