Embodiment Construction

[0049] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described below in conjunction with the accompanying drawings The program is described in further detail.

[0050]For the deep learning model of the safety driving assistance system, there may be target objects to be identified inside and outside the drivable area of ​​the vehicle. For example, the target objects can include motor vehicles, non-motor vehicles, and people driving on the road etc., as well as motor vehicles, non-motor vehicles, personnel, etc.

[0051] Among them, outside the drivable area, the target object may be occluded by the background (other objects except the target to be recognized), such target object c...

Abstract

The invention provides an alarm method and device for a driving assistance system and electronic equipment, and the method comprises the steps: inputting a collected current image into a trained deeplearning model, so as to enable the deep learning model to recognize a target object in the current image, wherein the deep learning model is obtained by training a sample image in a specified training sample set, the specified training sample set comprises a sample image carrying a specified negative sample, a target object does not exist in a position indicated by the specified negative sample of the sample image, a sample label of a sample image in the training sample set comprises a target attribute, and the target attribute represents whether a target object corresponding to the sample label is shielded or not; and determining whether a preset alarm strategy is satisfied based on an identification result of the deep learning model, and if yes, outputting alarm information. According to the invention, the false alarm probability is effectively reduced, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of intelligent driving, in particular to an alarm method, device and electronic equipment for a driving assistance system. Background technique [0002] The Safe Driver Assistant System (SDAS) can use the monitoring equipment installed on the vehicle (such as cameras and sensors) to collect environmental parameters inside and outside the vehicle, and carry out identification, detection and tracking of static and dynamic objects. Prompt the driver of possible dangers when necessary, so as to effectively reduce the probability of accidents and reduce accident injuries. [0003] In related technologies, a deep learning model is usually used to process the image collected by the monitoring equipment, output the position information and category information of the target object to be identified in the image, and further check whether the output result meets the preset alarm strategy, and then Alarm when the alar...
