Abstract

The invention relates to a video acquisition system supporting parallel preprocessing. A hardware realization apparatus of the video acquisition system comprises a data acquisition end and a data processing end. The data acquisition end comprises two SOC systems, i.e., an image sensor module and an online preprocessor, for acquiring monitoring video information and performing real-time analysis and preprocessing on data. Modules of the data processing end are integrated on one SOC system, for performing further operation processing and storage on the received data. According to the invention, sampling data is preprocessed in real time in a parallel and efficient mode, the modules are integrated on the SOC system, the data high-speed computation performance is enhanced, occupation of buses and memory resources and burden of a microprocessor can be reduced, the system cost and power consumption are reduced, and the system provided by the invention can be applied to such scenes as smart street lamps, wearable equipment, smart glasses, intelligent medical service, intelligent houses, enhanced reality equipment and the like at the same time.

Description

technical field [0001] The invention relates to a video acquisition system supporting a parallel preprocessor, which is a video acquisition system with an online parallel preprocessing function, including a data acquisition terminal and a data processing terminal. Background technique [0002] In recent years, monitoring equipment has spread all over the streets and alleys. The monitoring system is one of the most widely used systems in the security system, and video monitoring is now the mainstream. From the earliest analog monitoring to the fiery digital monitoring in the past few years to the current network video monitoring in the ascendant, the development status of monitoring equipment has undergone earth-shaking changes. However, these devices often have a single function, usually only recording but no analysis and processing functions. In a busy working environment, people often have to check a lot of monitoring data to find the information they want, and it is diff...
