[0028] After connecting the device to the camera, photos of medium and large animals taken in the wild will have clear laser dots. Based on the length of the telescopic rod adjusted by the telescopic device 3 and the ratio of the two laser dots to the body length of the animal in the animal photo, the body length of the observed animal can be easily estimated, specifically:

[0029] Assuming the device can arbitrarily adjust the distance between the two laser lights 1 to l, after taking a photo of a medium-to-large animal, assuming the proportionally reduced length of the medium-to-large animal in the photo is X (measured using a ruler), and the distance between the two laser points on the medium-to-large animal's body is x, the formula for calculating the large animal's body length L is as follows:

[0030]

After the observation device is assembled, adjust the distance between the two laser lights and set it to l. Then, take a photo of a medium-sized or large animal. After taking a photo of the medium-sized or large animal, assume that the proportionally reduced length of the medium-sized or large animal in the photo is X (measured using a ruler), and the distance between the two laser points on the body of the medium-sized or large animal is x. Then, calculate the body length L of the medium-sized or large animal. The specific formula is as follows:

[0032]

[0033] The utility model proposes a body length observation device for large and medium-sized animals in the wild with a camera. The distance between laser lights is controlled by adjusting a telescopic device. In combination with a camera taking photo, the body length of the animal is calculated by observing the photo later.
