A control method of a smart camera for a parking lot

Abstract

The invention discloses a method for controlling an intelligent camera for a parking lot. According to the technical scheme, the method for controlling the intelligent camera for the parking lot comprises an FPGA programmable device, a DSP, an ARM processor, an RAM memorizer and input / output interfaces, and the input / output interfaces comprise a CCD / CMOS interface, a video streaming interface, an I / O interface, an internet interface and a serial interface. The method for controlling the intelligent camera for the parking lot comprises the following steps that (1) the ARM processor monitors the input / output interfaces, receives control instructions, classifies the control instructions according to preset rules, and sends the control instructions to the FPGA programmable device and / or the DSP processor to process, wherein the control instructions comprise vehicle license plate recognition instructions and corresponding program instructions for calling internal storage, and if the control instructions are the vehicle license plate recognition instructions, a step 2 is executed to carry out vehicle license plate recognition process; (2) the vehicle license plate recognition process is carried out; (3) corresponding programs of the internal storage are called and executed.

Description

technical field [0001] The invention relates to a smart camera, in particular to a control method for a smart camera used in a parking lot for industrial detection. Background technique [0002] At present, the rapid development of industrial technology has prompted image processing technology to replace manual inspection of product surface defects under the increasingly high labor cost, which has brought a technological update revolution competition to domestic and foreign enterprises. For example, in the field of smart cameras for parking lots, the current smart cameras and system structures used in industrial inspection are mainly the following types: The first is that domestic companies can master more computer vision systems, which require PC + acquisition card + Camera + image processing software, its characteristics are: the camera adopts an ordinary analog camera for security monitoring, and after being collected by the acquisition card, it is analyzed by the license...
