The invention provides an inspection
robot instrument image recognition method and
system based on
computer vision, and the method comprises the steps: constructing a three-dimensional
space model ofa to-be-inspected scene, presetting an inspection
route of an inspection
robot, and presetting a photographing point position according to the position, orientation and illumination conditions of a target instrument; performing shooting calibration on the specified instrument based on the designed inspection
route and the designed shooting point to obtain the model, the range, the instrument template picture and the shooting point number of the specified instrument; enabling the inspection
robot to arrive at each inspection point along the inspection
route according to a specified serial number sequence, shooting the instrument according to a preset shooting point position, encoding the obtained instrument picture, positioning the instrument according to a
template matching algorithm, andperforming reading identification by utilizing an instrument identification
algorithm corresponding to a pointer instrument or a digital instrument. According to the invention, the problems of insecurity of manual inspection and
instability and difficult parameter adjustment of a traditional instrument image recognition method are solved, and the accuracy of instrument image recognition is greatlyimproved.
