Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as figure 1 As shown, a monitoring method for security technical services, which includes the steps of three-dimensional scene full-truth modeling, intelligent recognition, geometric correction, color gamut adjustment, image splicing and image fusion, the specific steps are as follows:
[0020] Step 1, establish a static 3D scene corresponding to the monitoring area of each camera within the monitoring range;
[0021] Step 2, identify and match each monitoring area with the 3D scene;
[0022] Step 3, mapping the monitoring images of each camera from a two-dimensional image to a thre...

The invention relates to a monitoring method for security technology service, which comprises the following steps: step 1, establishing a static three-dimensional scene corresponding to the monitoringarea of each camera in the monitoring range; step 2, identifying and matching each monitoring area with the three-dimensional scene; step 3, mapping a monitoring image of each camera into a three-dimensional curved surface space from a two-dimensional image; step 4, carrying out color adjustment on each monitoring image mapped to the three-dimensional curved surface space, wherein the color gamutis unified, and the overall image color is displayed consistently; step 5, selecting continuous monitoring images mapped to the three-dimensional curved surface space, carrying out splicing at the joint between the continuous monitoring images, so that the space scenes in the three-dimensional curved surface space are continuously transmitted; step 6, fusing the overlapped edges of all the monitoring images, so that different cameras can obtain the monitoring images into a whole, a three-dimensional scene corresponding to the complete monitoring range is obtained; wherein a removing step is further included before the step 1 and is used for removing the invalid monitoring ranges in the monitoring area.
Description
technical field [0001] The invention relates to the field of technical services, in particular to a monitoring method for security technical services. Background technique [0002] Due to the lack of overall scene information of the monitoring area in the existing monitoring system, it is difficult to effectively associate the two-dimensional monitoring video with the actual three-dimensional environment. Due to the lack of seamless fusion and centralized display of multi-mode and multi-quantity image information, it is impossible to grasp and control the overall real-time situation of the large scene, so it cannot really provide effective means for overall correlation and comprehensive scheduling. [0003] Each sub-camera surveillance video has only a partial perspective. For areas covered by multiple cameras, in order to obtain the video with the best perspective, it mainly relies on time-consuming and laborious manual selection, which may cause analysis deviations, errors...
