The invention provides a parking space multi-discrimination fusion analysis method, and the method comprises the following steps: S1, obtaining a visual parking space region and an ultrasonic parking space region; s2, calculating the visual parking space area and the ultrasonic parking space area through an overlapping equation to obtain an overlapping rate and an overlapping area; judging whether the parking space is fused or not according to the overlapping rate and the overlapping area, if yes, calculating fusion parking space attributes through a fusion equation to obtain an actual safe parking space area, and if not, analyzing according to the visual parking space area and the ultrasonic parking space area to obtain the actual safe parking space area; s3, according to the actual safe parking space area and the vehicle attribute information, a vehicle door opening angle limit value is calculated through a comparison equation, whether the parking space is abandoned or not is judged according to the angle limit value, if yes, a parking space reselection instruction is given to the vehicle, and if not, a parking space entering instruction is given to the vehicle; the method has the advantages that the existing visual analysis and ultrasonic analysis can be reasonably fused, and the actual safe parking space range can be accurately analyzed.

    本发明提供一种车位多判别融合分析方法,包括以下步骤,步骤S1,获取视觉车位区域和超声波车位区域;步骤S2,将视觉车位区域和超声波车位区域通过重叠算式计算得到重叠率和重叠面积;根据重叠率和重叠面积判断是否融合车位,若是,则通过融合算式计算融合车位属性得到实际安全车位区域,若否,则根据视觉车位区域和超声波车位区域分析得到实际安全车位区域;步骤S3,根据实际安全车位区域与车辆属性信息通过比较算式计算得到车门打开的角度极限值,根据角度极限值判断是否放弃车位,若是,则给予车辆重新选择车位指令,若否,则给予车辆入库指令;本发明的优点是能够将现有的视觉分析和超声波分析合理的融合准确的分析出实际安全的车位范围。
