Embodiment Construction

[0045] The present application will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0046] see figure 1 As shown, the embodiment of the present invention provides a facility system for AVM image calibration, including a scanning device 1, a control device 2, a first guiding device 3, a second guiding device 4, and a laser imaging system 5, and the control device 2 is connected to And control the scanning device 1 , the first guiding device 3 , the second guiding device 4 , and the laser imaging system 5 .

[0047] When the vehicle 6 enters the test room, the scanning device 1 scans the model logo of the vehicle 6 to obtain the vehicle model data. After the subsequent vehicle 6 enters the test room, the distance between the ground icons projected around the vehicle body can be adjusted according to the size difference of different models. distance, so that the four cameras installed around the body of the AVM can collect en...

Abstract

The invention discloses a facility system for AVM (All View Monitor) image calibration and a calibration method, and relates to the technical field of AVMs, and the method comprises the steps: scanning a vehicle model identifier of a vehicle to obtain vehicle model data, carrying out the processing of the vehicle model data to obtain a guide signal, guiding the vehicle to a first position in a test room according to the guide signal, and guiding the laser imaging system to a second position in the test room according to the guiding signal, and projecting four ground icons to designated positions around the vehicle after the laser imaging system reaches the second position. The vehicle and the laser imaging device can be guided to reach the designated position according to the vehicle type, the laser imaging device projects the calibration pattern to the periphery of the vehicle, and the problem that an existing calibration site limits the vehicle type is solved.

Description

technical field [0001] The present application relates to the technical field of AVM, in particular to a facility system and a calibration method for AVM image calibration. Background technique [0002] With the popularization of automobiles, the size of the body is increasing day by day, resulting in blind spots around the car, and the driver cannot see the surrounding conditions of the car clearly, which poses a safety risk. Therefore, more and more stringent driving requirements are put forward for the auxiliary driving equipment of automobiles, and the panoramic image monitoring system emerges as the times require. [0003] AVM is a system that shoots images through multiple (generally four) ultra-large wide-angle fisheye lenses, and performs distortion correction and splicing on the captured images through special algorithms to form a panoramic image around the object. The driver can observe the surroundings of the car through the vehicle multimedia screen. The 360° re...
