Abstract

The present invention provides a vehicle target detection method, wherein the vehicle target detection method includes: acquiring an image in front of the vehicle; dividing the image into a plurality of sub-images; judging whether the sub-images meet a predetermined condition; Any sub-image in a plurality of predetermined conditions is excluded, and the remaining sub-images are set as target sub-images, wherein the plurality of predetermined conditions include: the real distance of the object in the sub-image in front of the vehicle is greater than the first A predetermined distance, the real height of the object in the sub-image exceeds the predetermined height range, the real width of the object in the sub-image exceeds the predetermined width range, the distance between the center point of the sub-image and the side portion adjacent to the sub-image on the vehicle The distance between them is greater than a second predetermined distance; identifying the target in the target sub-image. The invention also provides a vehicle object detection device and a vehicle. Whether an image includes a target can be quickly detected by using the target detection method for a vehicle.

Description

technical field [0001] The present invention relates to the field of assisted driving, and in particular, relates to a vehicle target detection method, a vehicle target detection device and a vehicle including the vehicle target detection device. Background technique [0002] With the development of intelligent technology, many driving assistance devices have been produced. For example, there have been devices that assist parking, devices that automatically detect objects in front of the vehicle and generate reminder signals, and so on. [0003] The above-mentioned driving assistance device can detect the device in front of or behind the vehicle through infrared technology, and can also detect the device in front of or behind the vehicle by taking pictures. [0004] In order to improve the degree of intelligence, the method of taking pictures is currently used to detect objects in front of or behind the car. However, due to the computationally intensive process of identify...
