Description

technical field [0001] The invention relates to the field of automobile auxiliary braking devices, in particular to an automobile auxiliary braking device for fast braking. Background technique [0002] The emergence of automobiles has changed the way humans travel. In recent years, intelligent driving has become a hot field. With the advancement of society and science and technology, the application of automobile auxiliary braking devices has had a huge impact on all aspects of people's lives. However, the current vehicle auxiliary braking device has a slow target recognition speed, which not only limits the application of the vehicle auxiliary braking device, but also greatly increases the danger during driving. [0003] Target contour recognition is an important means of target recognition. Due to the influence of noise, quantization error and other factors in practical applications, the target contour will inevitably be distorted. In order to accurately describe the cont...
