The first photosensitive assembly is arranged near the target area, can sense the illumination change around the target area, and is convenient to judge whether the target area (target object) needs light supplement, and when the first photosensitive assembly senses that the illumination intensity value generated by the ambient illumination change is smaller than or equal to a certain threshold value, the light emitting assembly starts to work.
In S2, the brightness of the light emitting assembly is adjusted according to the illumination intensity value of the first photosensitive assembly and the initial distance between the ranging apparatus and the target object.
Specifically, S2 further includes:

The distance measuring device mentioned in the present application may be a distance meter, in particular, a laser distance meter; the Light Emitting component can be Light Emitting Diode (LED).
If the light-emitting component is not started, the illumination intensity of the target area is enough at the moment, and light supplement is not needed.
In S3, an illumination intensity value of the second photosensitive element is obtained according to the brightness of the light emitting element.
In specific implementation, the second photosensitive assembly is located in the center of a pattern formed by the light emitting assembly, when the light emitting assembly is started, the distance measuring equipment can be guided by utilizing a machine vision algorithm to project a laser spot of the distance measuring equipment on the second photosensitive assembly, and the second photosensitive assembly can sense the change of illumination intensity to acquire the illumination intensity value of the second photosensitive assembly.
In S4, it is determined whether the fill-in light source needs to be turned on according to the illumination intensity value of the second photosensitive element.
After the illumination intensity value of the second photosensitive assembly is obtained, the illumination intensity value needs to be further judged, and when the second photosensitive assembly senses that the illumination intensity value is larger than the second threshold value and the third threshold value at the same time, illumination change information is transmitted to the light supplement light source. It should be noted that, if the illumination intensity value is only greater than the second threshold or only greater than the third threshold, or is less than or equal to the second threshold or less than or equal to the third threshold, the light supplement light source will remain off and will not be turned on.
The second threshold is 2 times of the average value of the illumination intensity within a certain time, can be adjusted according to requirements, and can automatically compare the illumination intensity value of the second photosensitive component with the average value of the illumination intensity within a certain time.
In S5, the brightness of the fill-in light source is adjusted according to the illumination intensity value of the first photosensitive element and the initial distance between the distance measuring device and the target object.
Specifically, the luminance of the fill-in light source is calculated according to the following formula:
Tb＝min(1,Kb×ln(L)/m)；
in the above formula, TbThe brightness of the light source is compensated, L is the initial distance between the distance measuring equipment and the target object, and KbM is the illumination intensity value of the first photosensitive element for the preset constant parameter. Optionally, the light emitting component is an LED.
Further included after S6 is: recording the starting time of the supplementary lighting; judging whether the difference value between the current time and the light supplement starting time is greater than a time threshold value or not; if yes, turning off the light supplementing light source; if not, the light supplementing light source is kept on.
The time threshold of the embodiment of the application may be a preset fixed value, such as 300 seconds, and may also be adjusted as needed.
The light supplementing light source can supplement light to the target area. The supplementary lighting source can be arranged near the target area and faces the target area, and can also be arranged on the back of the target and increases the brightness of the target through the semitransparent plate. The light supplementing light source can be an LED lamp, an incandescent lamp or an energy-saving lamp, and the brightness of the light supplementing light source can be adjusted at will without any limitation.

The first photosensitive assembly (sensor) senses the ambient illumination intensity of the target area, and whether the light-emitting assembly needs to be started is further judged. When the light supplementing light source needs to be started, the imaging coordinates of the light emitting components in the image are identified by using a machine vision algorithm, and the pixel coordinates of the center point of the pattern formed by the imaging coordinates of the light emitting components are calculated.
And calculating according to the pixel coordinates of the central point of the pattern to obtain a rotational angle of the holder, and rotating the holder of the distance measuring equipment according to the rotational angle of the holder, so that the laser spot of the distance measuring equipment falls on the second photosensitive assembly of the light supplementing device. The light supplementing device starts the light supplementing light source by judging the change of the illumination intensity value of the second photosensitive assembly. The pan head of the distance measuring device is rotated so that the distance measuring device is directed to the target area (target object) and acquires an image of the target area (target object).

And starting the distance measuring equipment to obtain the laser distance, and obtaining the space coordinate of the target point according to the rotating angle of the holder and the laser distance. Therefore, the distance measurement work is completed under the light supplement effect.
