However, in practical applications, due to the complex on-site environment, there may be various interferences in the screen, so that the camera of the measurement equipment does not focus on the target object, resulting in virtual focus of the target object, and the measurement work cannot be completed
In addition, since the pixel coordinates of the laser landing point of the video measurement equipment on the screen will change with the distance, the camera cannot be used to focus on a fixed area to solve the above problems

Embodiment 1
[0052] An embodiment of the present application provides a focusing method for a measuring device, such as figure 1 shown, including:
[0053] S1: Obtain the focus area of the shooting picture of the camera in the measuring device;
[0054] S2: Obtain the sharpness of the laser focus image in the focus area;
[0055] S3: Use the area focus algorithm to adjust the focus lens of the camera to focus on the focus area;
[0056] S4: Obtain the area focus image definition of the focus area;
[0057] S5: When the laser focus image definition is greater than the area focus image definition, adjust the focus lens of the camera.
[0058] In the above embodiments, the measuring equipment at least includes a camera, a laser range finder, and a pan / tilt, and the camera and the laser range finder are all installed on the pan / tilt. The working principle of the measuring equipment is to use the camera to obtain the video image containing the target object, turn the pan / tilt according to...
Embodiment 2
[0088] The application provides a focusing device for measuring equipment, including:
[0089] A focus area acquisition module 1, configured to acquire a focus area of a picture captured by a camera in the measuring device;
[0090] The sharpness acquisition module 2 is used to acquire the laser focused image sharpness and regional focused image sharpness of the focus area;
[0091] The area focusing module 3 is used to adjust the focusing lens of the camera by using the area focusing algorithm to focus on the focus area;
[0092] The adjustment module 4 is configured to adjust the focus lens of the camera when the laser focus image definition is greater than the area focus image definition.
[0093] Obtain the focus area of the image captured by the camera in the measuring device, calculate the sharpness of the focus area, and use it as the sharpness of the laser focus image. Use the area focus algorithm to adjust the focus lens of the camera, focus on the focus area ag...

Abstract
The embodiment of the invention provides a focusing method and device of measurement equipment, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring a focus area of a shot picture of a camera in the measurement equipment; acquiring the laser focusing image definition of the focus area; adjusting a focusing lens of the camera by using a region focusing algorithm, and focusing the focus region; obtaining the area focusing image definition of the focus area; and adjusting a focusing lens of the camera according to the laser focusing image definition and the area focusing image definition. Compared with the prior art, focusing of the camera is completed according to the comparison result of the laser focusing image definition and the area focusing image definition, and the definition of the focus area can be improved.
Description
technical field [0001] The present application relates to the technical field of measuring equipment, and in particular, relates to a focusing method, device, electronic equipment, and computer-readable storage medium for measuring equipment. Background technique [0002] Video measurement equipment is a device that combines real-time video images and laser ranging technology for space measurement. When working, the camera needs to be clearly focused on the target object for measurement. However, in practical applications, due to the complex on-site environment, there may be various interferences in the screen, so that the camera of the measurement equipment does not focus on the target object, resulting in virtual focus of the target object, and the measurement work cannot be completed. In addition, since the pixel coordinates of the laser landing point of the video measurement equipment on the screen will change with the distance, the camera cannot be used to focus on a fi...
