A method and device for prompting information to a target object

Abstract

An embodiment of the invention provides an information prompting method for a target object. The information prompting method comprises the steps of determining a first luminance value of the natural environment in the current geographic position of the target object; determining a second luminance value of the current region where the target object is located; determining the state of light source equipment in the current region according to a relation between the difference value, between the first luminance value and the second luminance value, and a threshold value; and prompting the state information of the light source equipment to the target object. In the scheme, the state of the light source equipment in the current region is determined according to the first luminance value of the natural environment and the second luminance value of the current region where the target object is located, and the state information is prompted to the target object; and therefore, the target object (such as a visual impaired person) can determine whether the light source equipment is started or closed, so that the problems existing in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method and device for prompting information to a target object. Background technique [0002] According to the data of the Second National Sample Survey on Disabilities, the number of visually disabled people in China is about 12.33 million, and about 450,000 people are blind every year. The visually impaired (including the blind) have limited mobility due to limited visual senses, which brings great troubles to life. [0003] At present, the following methods are mainly used to solve the inconvenience caused by the limited visual senses of the visually impaired: [0004] One way is to use a blind stick. As an auxiliary tool, the detection method is manual reciprocating point-by-point scanning. However, the spatial information obtained by using the blind stick is limited, and it is generally used to determine obstacles. It is used to determine the bicyc...

Problems solved by technology

[0004] One way is to use a blind stick. As an auxiliary tool, the detection method is manual reciprocating point-by-point scanning. However, the spatial information obtained by using the blind stick is limited, and it is generally used to determine obstacles. It is used to determine the bicycles parked in front, a wall in front, etc., and cannot be used to determine where there are traffic lights or zebra crossings and other targets;

[0005] There is also a way to use guide dogs. Guide dogs can generally remember a few fixed lines, but they can't judge where there are such targets as traffic lights or zebra crossings.

[0006] However, the above methods cannot help the visually impaired to identify whether the light source device needs to be turned off. For example, the blind is unable to determine if the light is turned on indoors.

[0007] Therefore, currently there is no method for identifying the need to turn off the light source device for the visually impaired
