MANAGING FEATURE DATA FOR ENVIRONMENT MAPPING ON AN ELECTRONIC DEVICE

An electronic device [100] reduces localization data [230] based on feature characteristics identified from the data [225]. Based on the feature characteristics, a quality value can be assigned to each identified feature [343], indicating the likelihood that the data associated with the feature will be useful in mapping a local environment of the electronic device. The localization data is reducedby removing data associated with features have a low quality value, and the reduced localization data is used to map the local environment of the device [235] by locating features identified from thereduced localization data in a frame of reference for the electronic device. 种电子设备[100]基于从数据识别的特征特性[225]简化的定位数据[230]。基于所述特征特性，质量值能够被分配给每个所识别的特征[343]，指示与该特征相关联的数据在映射电子设备的本地环境中将是有用的可能性。通过去除与具有低质量值的特征相关联的数据，定位数据被简化，并且通过在针对电子设备的参考系中定位从简化的定位数据中识别的特征，所述简化的定位数据被用于映射该设备的本地环境[235]。
