It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1, a method for testing a camera of an automatic positioning test card according to an embodiment of the present invention is described, which includes the following steps:
101. and detecting a first characteristic region from a test image shot by the camera to be tested, and determining the coordinate of the first characteristic region in the test image shot by the camera to be tested.
Referring to FIG. 7, for example, color test card A (color CHART) has a plurality of feature areas a1-a18, each representing a different color. The test image shot by the camera to be tested is C, so that the color test chart A is slightly deviated and does not form an image in the center of the test image C; in the prior art, the camera needs to be manually adjusted to eliminate the situation to remove the shooting error, but the present invention does not need to perform such an operation. In step 101, the feature region a1 may be selected as a first feature region, the first feature region a1 is detected from a test image C captured by a camera under test, and coordinates of the first feature region a1 in the test image C are determined.
102. And determining the coordinates of other characteristic areas in the test image shot by the camera to be tested according to the coordinates of the first characteristic area in the test image shot by the camera to be tested and the position relation of the first characteristic area and the other characteristic areas in the test image shot by the camera to be tested.
Referring to fig. 7, taking color test CHART a (color CHART) as an example, step 101 has detected the coordinates of first feature region a1 in test image C, the coordinates of feature regions a2-a18 in test image C can be determined according to the positional relationship between first feature region a1 and feature regions a2-a18 in test image C. For example, in the test image C, the distance between each feature region in the color test chart a and its upper, lower, left, and right feature regions is x, the coordinates of the feature region a2 in the test image C, and the coordinates of the feature regions a3-a18 in the test image C can be calculated from the coordinates of the first feature region a1 in the test image C.
103. And extracting each characteristic region from the test image shot by the camera to be tested according to the coordinate of each characteristic region in the test image shot by the camera to be tested, and generating a test result.
The embodiment of the invention adopts the method for determining the specific coordinates of the test chart according to the characteristics of the test chart to make up for the deviation caused by the deviation of the photographing view center of the camera, saves the manual method for adjusting the photographing view center of the camera, shortens the test time and greatly improves the test efficiency.
Referring to fig. 2, a method for testing a camera of an automatic positioning test card according to an embodiment of the present invention is described, which includes the following steps:
201. and detecting a first characteristic region from a test image shot by the camera to be tested, and determining the coordinate of the first characteristic region in the test image shot by the camera to be tested.
Referring to fig. 7, a test image shot by the camera to be tested is C, and it can be seen that the color test chart a is slightly shifted and does not form an image at the center of the test image C; in the prior art, the camera needs to be manually adjusted to eliminate the situation to remove the shooting error, but the present invention does not need to perform such an operation. In step 201, a first feature region a1 is detected from the test image C captured by the camera under test, and the coordinates of the first feature region a1 in the test image C captured by the camera under test are determined.
202. And calculating the deviation between the coordinates of the first characteristic region in the test image shot by the camera to be tested and the coordinates of the first characteristic region in the standard test image, and executing step 203.
Referring to FIG. 6, which shows a standard test image, it can be seen that color test card A is imaged in the center of standard test image B. In step 202, the deviation between the coordinates of first feature region a1 in standard test image B and the coordinates of first feature region a1 in test image C is determined.
Standard cameras can be used to pre-shoot to obtain standard test images: firstly, moving a standard camera to enable a test chart to be positioned in the center of the visual field of the standard camera, and then shooting to obtain a standard test image; and detecting the standard test image, determining the coordinates of the first characteristic region in the standard test image, and further determining the coordinates of other characteristic regions in the standard test image. Alternatively, the standard test image may not be obtained by real shooting, but the standard test image may be calculated according to the test constraint condition, so as to obtain the coordinates of the feature region in the standard test image.
203. And judging whether the deviation is within an allowable range, if so, executing step 204, and if so, executing step 205.
204. The coordinates of the other respective feature areas in the test image taken by the camera under test are calculated, i.e. in this embodiment, the coordinates of the feature areas a2-a18 in the test image C are determined. Step 206 is then performed.
The coordinates of the characteristic region a2-a18 in the test image C shot by the camera to be tested can be calculated in two ways:
one is to determine the coordinates of the other feature areas a2-a18 in the test image C taken by the camera to be tested according to the coordinates of the first feature area a1 in the test image C taken by the camera to be tested and the positional relationship of the first feature area a1 and the other feature areas a2-a18 in the test image C taken by the camera to be tested. Which may be shown with particular reference to the previous embodiment.
And the other one is to determine the coordinates of the other characteristic regions a2-a18 in the test image C shot by the camera to be tested according to the coordinates and the deviation of the other characteristic regions a2-a18 in the standard test image B.
205. And prompting that the camera to be detected is unqualified. If the deviation exceeds the allowable range, the assembly error of the camera to be detected is too large, and the camera to be detected is an unqualified product, so that the condition that the camera to be detected is unqualified is prompted.
206. And extracting each characteristic region from the test image shot by the camera to be tested according to the coordinate of each characteristic region in the test image shot by the camera to be tested, and generating a test result.
