Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of an image stitching test method according to an embodiment of the present invention, which is applicable to a situation that a stitching test is required, and the method may be executed by an image stitching test apparatus, and the apparatus may be implemented in a software and/or hardware manner, and may be integrated on a device, for example, a multi-view stitching device.
Referring to fig. 1B, point a is a perfectly stitched point in the stitched image, and point B is a point with abnormal stitching. The distance from point a to the camera is the optimal stitching distance for point a. Therefore, if the optimal splicing positions of all the points on the splicing seams are deduced, the measurement of the splicing effect of the equipment can be realized. From fig. 1B it can be deduced that point B and the real plane intersect at two points B' and B ". The points B ' and B ' can completely replace the points B in the visual angle of the spliced camera, and are equivalent points of the points B, namely in an optical system, the results generated by the points B ', B ' and B ' are the same. Hereby two points can be used to test the optimal stitching distance of the camera. Specifically, referring to fig. 1c, if there are two non-coincident points B ' and B ″ in a real plane, if B ' and B ″ intersect at the same point in the stitching camera frame, it is determined that the corresponding point B of B ' and B ″ on the virtual plane is the optimal stitching distance of the camera. On the basis, the method for carrying out the image splicing test indoors comprises the following steps:
s101, shooting two entities or non-entities in a real plane in real time, and splicing the shot images, wherein the relative positions of the two entities or the non-entities in the real plane are dynamically adjusted.
After the multi-view splicing device is erected indoors, parameters of the multi-view splicing device are recorded, for example, the distance from the multi-view splicing device to a real plane and the distance between two cameras on the multi-view splicing device are recorded. In the embodiment of the invention, the relative positions of the two entities or the non-entities in the real plane are dynamically adjusted, for example, the two entities or the non-entities are controlled to move oppositely, meanwhile, the two entities or the non-entities moving oppositely in the real plane are shot in real time by utilizing a multi-view splicing device, and the shot images are spliced.
And S102, repeating the step S101 until the specified points on the two entities or the non-entities in the spliced image are superposed.
The designated point may be two real or non-real predetermined points, for example, two non-real points are triangles with opposite vertices, and the opposite vertices of the two triangles may be the designated point. When the two designated points coincide, the designated points on the two entities or the non-entities are two equivalent points of the target point on the image seam. Therefore, the optimal splicing distance of the target point on the image splicing seam can be calculated according to the distance between two solid or non-solid designated points.
S103, determining the distance between the designated points on the two entities or the non-entities, and calculating the optimal splicing distance from the target point to the multi-view splicing device by combining the parameters of the multi-view splicing device, wherein the optimal splicing distance is used for measuring the splicing effect of the multi-view splicing device.
The distance between two designated points of an entity or a non-entity comprises a transverse distance and a longitudinal distance, wherein the transverse distance is the horizontal distance of one designated point relative to the other designated point, and the longitudinal distance is the vertical distance of one designated point relative to the other designated point; illustratively, a xoy coordinate system is established in a real plane, wherein the transverse distance is the distance between two entities or non-entities along the direction of an x axis, and the longitudinal distance is the distance between the two entities or non-entities along the direction of a y axis; the parameters of the multi-view splicing equipment at least comprise the distance from the multi-view splicing equipment to a real plane and the distance between two cameras, wherein the real plane is a real planeThe plane is a plane on which the solid or non-solid is placed. The operation of calculating the optimal splicing distance from the target point to the multi-purpose splicing device comprises the following steps: and calculating the optimal splicing distance of the multi-view splicing equipment according to the distance from the multi-view splicing equipment to a real plane, the distance between the two cameras, the transverse distance and the longitudinal distance. Illustratively, it can be according to a formula
And calculating, wherein K represents the optimal splicing distance, D represents the distance from the multi-view splicing device to a real plane, D represents the distance between two cameras of the multi-view splicing device, and x represents the transverse distance between two designated points on an entity or a non-entity. Therefore, the optimal splicing distance of a target point on the splicing seam can be calculated.
Based on the same theoretical method, taking a double-sided splicing device as an example, by placing a plurality of pairs of entities or non-entities on a real plane, the respective splicing distances of a plurality of points on a splice can be measured simultaneously. Illustratively, as shown in fig. 1d, two rows of test cards (i.e., non-solid) are placed on a solid plane, each row includes 8 isosceles triangle cards numbered 1 to 8, the positions of the two rows of test cards in the solid plane are adjusted, the two rows of test cards are photographed in real time during the adjustment process, and the photographed images are spliced until the positions of the vertexes (i.e., designated points) of the two rows of test cards in the camera picture are all overlapped, the overlapped images are referred to fig. 1e, the transverse distance and the longitudinal distance between each pair of triangular test cards (i.e., test cards with the same number) in the solid plane are calculated, and the optimal splicing distance between 8 points in the splice can be calculated through the above formula. For exemplary, measured data see table 1.
TABLE 1 measurement results
Furthermore, after the optimal splicing distance from each point on the seam to the multi-purpose splicing device is obtained, a curve graph of the optimal splicing distance from each point on the seam is drawn, wherein the curve graph is used for analyzing the splicing effect of the multi-purpose splicing device. Illustratively, the splicing effect of the equipment can be judged according to the trend of the graph because the splicing distance of the points is smaller as the points are closer to the camera.
The embodiment of the invention shoots two entities or non-entities moving oppositely in a real plane in real time, splices the shot images until the appointed points on the two entities or non-entities in the spliced image coincide, the appointed points on the two entities or non-entities are two equivalent points of a target point on the image splicing seam, and calculates the optimal splicing distance from the target point to the multi-view splicing device by determining the distance between the appointed points on the two entities or non-entities and combining the parameters of the multi-view splicing device. Therefore, the embodiment of the invention can finish the test of the optimal splicing distance of the splicing points only by measuring the distance between equivalent entities or non-entities of the splicing points in the real plane and integrating the equipment parameters, does not need real-scene test, reduces the test labor and improves the test precision.

As shown in fig. 2a, the method comprises:
s201, aiming at any actual scene, calculating a standard splicing distance of the multi-view splicing equipment in the actual scene according to the corresponding installation parameters of the multi-view splicing equipment.
In the embodiment of the invention, each actual scene is respectively corresponding to a mathematical model for calculating the optimal splicing distance. For example, referring to fig. 2b, taking an open and building-free blocked spliced scene as an example, a mathematical model for calculating an optimal splicing distance K in the scene is a function of a viewing angle bisection coefficient n, specifically as follows, where α is a bisection angle, h is an installation height, and θ is an included angle between a connecting line between a closest point captured by the camera and a ground plane:
K＝h*tan(θ+nα)
and calculating to obtain the standard optimal splicing distance under the scene, which is shown in table 2.
TABLE 2 results of calculation
S202, calculating the deviation between the optimal splicing distance and the standard splicing distance, and determining the adaptability of the multi-view splicing equipment in the actual scene according to the calculation result.
After the optimal splicing distance is measured in the above embodiment, the deviation between the optimal splicing distance and the standard splicing distance is calculated only according to a deviation calculation formula, and the adaptability of the multi-view splicing device in the actual scene is determined according to the calculation result. In addition, a standard splicing distance curve graph can be drawn according to the data measured in the scene, the optimal splicing distance curve graph measured in the embodiment is fitted with the standard splicing distance curve graph through a fitting tool, and the adaptability of the multi-view splicing device in the actual scene is judged according to the set result.
In the embodiment of the invention, the adaptability of the multi-view splicing equipment in an actual scene can be determined by calculating the deviation between the optimal splicing distance and the standard splicing distance, so that a basis is provided for the installation of the subsequent multi-view splicing equipment.
