距离#
介绍#
距离传感器可以探测正前方的物体并测量其距离。第一代传感器使用声纳进行探测,而第二代传感器使用教室安全激光,还可以估算物体的大小和速度。
For the examples below, the configured Distance Sensors will be named distance_1
and will be used in all subsequent examples throughout this API documentation when referring to Distance
and Sonar
class methods.
以下是所有可用方法的列表:
Getters – 从距离传感器返回数据。
is_object_detected
– (1st and 2nd Gen) Returns whether an object is within range.distance
– (1st Gen) Returns the distance to the nearest object.object_distance
– (2nd Gen) Returns the distance to the nearest object in inches, millimeters, or centimeters.object_velocity
– (2nd Gen) Returns the speed of a detected object in meters per second.object_size
– (2nd Gen) Returns the estimated size of the detected object (small, medium, large).installed
– (1st and 2nd Gen) Returns whether the Distance Sensor is connected to the Brain.

is_object_detected#
is_object_detected
returns a Boolean indicating whether the Distance Sensor detects an object within range.
True
- The Distance Sensor detects an object.False
- The Distance Sensor does not detect an object.
Usage:
distance_1.is_object_detected()

distance#
distance
returns the current distance from the Distance Sensor and a detected object as a float.
**注意:**这是一种(第一代)距离传感器方法。

object_velocity#
object_velocity
returns the velocity of a detected object as a float, measured in meters per second. A positive value indicates the object is moving toward the Distance Sensor (2nd gen), while a negative value indicates it is moving away.
**注意:**这是一种(第二代)距离传感器方法。
Usage:
distance_1.object_velocity()

# Example coming soon
object_size#
object_size
returns an ObjectSizeType
, which represents the estimated size of the detected object based on how much of the Distance Sensor (2nd gen)’s field of view it occupies:
ObjectSizeType.NONE
– No object is detected, or the object is so close that it fills the entire field of view.ObjectSizeType.SMALL
– The object occupies a small portion of the field of view.ObjectSizeType.MEDIUM
– The object occupies roughly half of the field of view.ObjectSizeType.LARGE
– The object occupies most of the field of view.
**注意:**这是一种(第二代)距离传感器方法。
Usage:
distance_1.object_size()

installed
returns a Boolean indicating whether the Distance Sensor is connected to the Brain.
True
- The Distance Sensor is connected to the Brain.False
- The Distance Sensor is not connected to the Brain.

构造函数#
Constructors are used to manually create Distance
and Sonar
objects, which are necessary for configuring a Distance Sensor (2nd gen) or (1st gen) outside of VEXcode.
Sonar#
Sonar
creates a Distance Sensor (1st gen).
Usage:
distance_1 = Sonar(port)
