Abstract：The optimal configuration of the field angle of industrial cameras plays an important role in improving the image quality of targets.However,there is a certain blindness in the configuration of field angle,which leads to a large number of wasted pixels of image sensors.To this end,an optimal configuration method for field angle of industrial cameras based on the imaging area model is proposed.Firstly,establishing a three-dimensional coordinate system in space to quantitatively describe the industrial imaging scene.Then,an imaging area model is established based on the spatial coordinate transformation to reveal the quantitative relationship among the field angle,imaging direction and imaging area of industrial cameras.Finally,an optimization configuration algorithm for field angle based on the bisection-particle swarm is designed to obtain the image of the complete target by the minimum field angle of industrial cameras.The experimental results show that after using the proposed method to optimize the configuration of field angle,the pixels of image sensors are fully utilized,and the image quality is significantly improved,which can provide a reliable reference for the selection of the field angle of industrial cameras.
