The invention provides an energy-consumption -accuracy controllable sensor dual-
parameter distribution system comprising a sensor and a
server which are connected via a
transmission channel, wherein atraining mode of the
system statistically analyzes internal relations between performance indexes such as coding
energy consumption, transmission
energy consumption and scene classification, and twocontrol parameters, and builds an accuracy parameter optimization model between an accuracy threshold and an (S, Q) control parameter through analyzing how a sampling factor S and a quantization parameter Q influence characteristics such as coding complexity, a
bit rate and
image quality, of a monitoring image. The working mode of the
system can preset a proper (S, Q) control parameter according to an accuracy parameter optimization model, to gradually adjust
energy consumption of the sensor under the constraint of classification accuracy, and acquire approximately optimal energy-consumption-accuracy control performance. According to the system provided by the system, a computing method for the control parameter is provided through testing the characteristics such as the coding complexity,
bit rate and accuracy, of intelligent
wireless image monitoring, and an energy consumption-accuracy controllable mechanism is provided for a monitoring and imaging application.
