Problems solved by technology

[0004] However, for the outdoor parking lot, if the outdoor parking lot is in a scene of sandy soil, it is difficult to install a wireless geomagnetic detection sensor on the sandy soil, and it is difficult to identify the currently parked vehicles in the outdoor parking lot, and thus Unable to identify vacant parking spaces, unable to remind users of vacant parking spaces, and ultimately unable to guide users

Embodiment Construction

[0049] The specific implementation manners of a target object recognition method and device provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050]An embodiment of the present invention provides a method for identifying a target object, which is applied to an outdoor parking lot. The area where the outdoor parking lot is located includes at least one area to be identified, the area to be identified includes a plurality of sub-areas, and the area to be identified is correspondingly provided with a camera ;Such as figure 1 As shown, the identificati...

Abstract

The invention discloses a target object identification method and device. If more target objects exist in the reference image, the ratio of the first weight to the second weight can be increased, themisjudgment probability of the target objects in the recognition process can be reduced, the recognition accuracy of the target objects is improved, and the responsivity of the background in the recognition process is reduced, so that the authenticity of the recognition result of the target objects is improved. Moreover, according to the embodiment of the invention, the reference image is identified according to the target identification model; a target object in the subarea is determined according to an identification result; therefore, when the identification method is applied to the application scene of the outdoor parking lot, even if the outdoor parking lot is located in the sand land, the identification of the vehicle is not influenced, so that the idle parking space can be determined according to the determined parked vehicle, the user is guided, and the experience feeling of the user is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a target object recognition method and device. Background technique [0002] In the management process of the parking lot, in order to remind the user of the number of vehicles that can be parked in the parking lot and the number of current free parking spaces, it is necessary to count and identify the currently parked vehicles in the parking lot. [0003] At present, for indoor parking lots, wireless geomagnetic detection sensors can generally be installed in the indoor parking lot; specifically, the indoor parking lot includes several parking spaces, each parking space can be provided with a geomagnetic detection device, Connect with the signal receiving base station, so that the geomagnetism detection device can send the obtained parking space status to the signal receiving base station. When the signal receiving base station is connected to the application server, af...
