When the target object has a hole, the product will identify different distance information for the area with a hole and the area without a hole. For the area with a hole, the product will calculate the actual distance information of the object; for the area without a hole, because the returned light will travel a shorter distance, the product will calculate a nearer distance information.
By identifying the distance data of the target object, the product will upload the distance information of all objects in the entire image to the monitoring computer. The host computer will analyze the distance data to obtain the size information of the object.
