Embodiment 1

[0040] like figure 1 As shown, the present invention provides a test site for panoramic parking calibration. The test site 1 is used to provide a site for panorama correction for vehicles equipped with a panorama parking system. The test site 1 includes: a parking line 11 , a central axis 12 , a first calibration test area 13 , a second calibration test area 14 , and a third calibration test area 15 .

[0041] The parking line 11 is used to indicate the parking position of the front end of the vehicle. In this embodiment, the stop line 11 is located at the middle front of the test site 1 to remind the driver of the vehicle to stop the front of the vehicle above the line.

[0042] The central axis 12 is perpendicular to the parking line 11 and is used to demarcate the central axis of the vehicle. In this embodiment, the central axis 12 bisects the parking line 11 , which is used to prompt the driver of the vehicle to park the vehicle in the middle on the central axis 12 .

Embodiment 2

[0072] The present invention also provides a method for building a test site 1 for panoramic parking calibration.

[0073] The method of constructing the test site 1 is as follows:

[0074] Mark the parking line 11 used to indicate the parking position of the front end of the vehicle at the test site 1, and the central axis 12 perpendicular to the parking line 11 and used to mark the central axis of the vehicle;

[0075] In the first calibration test area 13 in front of the vehicle, the first calibration point a5 is arranged on the central axis 12 according to a preset value away from the parking line 11;

[0076] In the first calibration test area 13 in front of the vehicle, the first calibration points a1 and a2 symmetrical along the central axis 12 are arranged obliquely in front of the vehicle according to the preset distance from the parking line 11 and the central axis 12, wherein The preset distance d1 of the central axis 12 is greater than half of the stop line 11;

...

Embodiment 3

[0086] As a preferred option, such as Figure 2a , 2b , 2c, according to the above-mentioned respective first calibration points, second calibration points and third calibration points and the corresponding positional relationship between the parking line 11 and the central axis 12, the above-mentioned first calibration test area is made in advance 13. The patch of the second calibration test area 14 and the third calibration test area 15 . The first calibration test area 13 , the second calibration test area 14 , and the third calibration test area 15 can be made of polyvinyl chloride, polypropylene and other non-deformable plastic cloth or advertising cloth.

[0087] The method of constructing the test site 1 is as follows:

[0088] Mark the parking line 11 used to indicate the parking position of the front end of the vehicle at the test site 1, and the central axis 12 perpendicular to the parking line 11 and used to mark the central axis of the vehicle;

[0089] Accordin...

Abstract

The invention provides a testing site for whole scene calibration and a constructing method of the testing site for the whole scene parking calibration. The testing site for the whole scene parking calibration comprises a parking line, central axial lines perpendicular to the parking line and evenly dividing the parking line, a first calibration testing zone arranged in front of a vehicle and connected with the parking line, second calibration testing zones arranged at two sides of the vehicle respectively and a third calibration testing zone arranged behind the vehicle and keeping a preset distance away from the parking line. The first calibration testing zone comprises a plurality of first calibration points and a plurality of second calibration points. Each second calibration testing zone comprises second calibration points. The third calibration testing zone comprises a plurality of second calibration points and a plurality of third calibration points. A straight line parallel to the central axial lines is formed by the first calibration points, the second calibration points and the third calibration points, wherein the first calibration points, the second calibration points and the third calibration points are arranged at the same side of the vehicle. The first calibration points and the third calibration points are arranged on the central axial lines. Each first calibration point, each second calibration point and each third calibration point are respectively marked with a sequence number. The testing site is constructed according to positional relationship of the calibration points and the positional relationship of the calibration points, the parking line and the central axial lines in the testing site.

Description

technical field [0001] The invention relates to a test site for panoramic parking calibration and a construction method thereof. Background technique [0002] The panoramic parking calibration test is used to correct the images captured by the cameras installed at the front, rear, left and rear of the vehicle body, with the purpose of seamlessly splicing the images captured by each camera. The panoramic parking calibration test site is used to provide a convenient test environment. At present, the commonly used test site is a test site with zebra crossings or checkerboard patterns. Seam errors (such as zebra crossing misalignment, checkerboard dislocation, etc.) are used to adjust the deflection angle of the corresponding image, so that the gap between the stitched images is the smallest. [0003] The above-mentioned test site needs to ensure that the pattern is complete when laying, and the mismatch of zebra crossings or checkerboards will affect the accuracy of the panora...
