The invention discloses an intelligent greenhouse nectarine fruit growth rate wireless monitoring system based on an embedded dual-camera platform. The system comprises a dual-camera module, a dual-core processor and a remote server, wherein the dual-core processor comprises an ARM module and a DSP (Digital Signal Processor) module; the dual-camera module is used as signal input of the monitoringsystem and used for fruit image acquisition of nectarine; a signal output end of the dual-camera module is connected with an image signal input end of the ARM module; the ARM module and the DSP module are in bidirectional connection; the DSP module is used for processing the image data and extracting the volume of the nectarine fruit; and the ARM module communicates with the remote server througha 3G communication module. In the invention, two USB cameras are matched with the embedded technology and the 3G wireless transmission technology to perform remote real-time monitoring on the growth of the greenhouse nectarine fruit, and the problems in terms of data acquisition and data teletransmission in the detection process of fruit growth rate are solved.
