→Real-timeness, frame dropping, and latency
A new frame is sent by the image sensor to the processing platform every 3ms approximately. Taking into account that the sensor has no buffering capabilities, this implies that the processing platform has to complete the acquisition of a frame in less than 3ms although the arrival of a new frame is an asynchronous event.
Despite these considerations, a system not specifically designed with real-time capabilities was used to limit the implementation effort and the costs. Rather, it was used decided to use a platform providing enough headroom in terms of processing powerand to verify experimentally the fulfillment of requirements. NeverthelessBasically, two methods were utilized for this verification.# At the application software implements level, a mechanism able to detect any frame loss allowing to verify if the system is operating properlywas implemented.Incidentally, this mechanism exploits frame timestamp described
