When the contours of any obstacle have a human shape, analyzing an extent of the range of the blind area of the vehicle from the images and determining whether an obstacle is within the blind area range of the driven vehicle. If any obstacle is determined to be in the blind area, generating an alarm to the driver of the vehicle by implementing the 5G communication method to activate the alarm device.

Abstract: A method comprises obtaining an intermediate representation of the machine learning model written in a source language. The intermediate representation is independent of the source language and a target language and comprises a structured text. The method also comprises generating a computation graph based on the intermediate representation. Nodes in the computation graph represent functions related to the machine learning model and a directed edge in the computation graph represents a dependency between functions. The method further comprises partitioning the computation graph into sequential parts in sequence such that the parts are executed sequentially, and functions corresponding to nodes in each part are executed in parallel.

Abstract: The present invention provides a reference fingerprint of virgin olive oil, and an establishment method and an application thereof. By using UPLC-FLD, the chromatographic information of various components in the extra virgin olive oil is obtained, breaking through the limitation of establishment of fingerprints by means of conventional GC-MS method and based on the fatty acid composition of edible oil, and further solving the problem that traditional fingerprints only use a single component for determination and thus result in false positivity.
